WordPress: Bitnami Docker Image for WordPress

WordPress packaged by Bitnami

What is WordPress?

WordPress is the world's most popular blogging and content management platform. Powerful yet simple, everyone from students to global corporations use it to build beautiful, functional websites.

Overview of WordPress

TL;DR

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-wordpress/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Warning: This quick setup is only intended for development environments. You are encouraged to change the insecure default credentials and check out the available configuration options in the Environment Variables section for a more secure deployment.

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading Linux distribution.
  • All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
  • Bitnami container images are released daily with the latest distribution packages available.

This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

How to deploy WordPress in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami WordPress Chart GitHub repository.

Bitnami containers can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

Get this image

The recommended way to get the Bitnami WordPress Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/wordpress:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

$ docker pull bitnami/wordpress:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/wordpress:latest 'https://github.com/bitnami/bitnami-docker-wordpress.git#master:5/debian-10'

How to use this image

WordPress requires access to a MySQL or MariaDB database to store information. We'll use the Bitnami Docker Image for MariaDB for the database requirements.

Run the application using Docker Compose

The main folder of this repository contains a functional docker-compose.yml file. Run the application using it as shown below:

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-wordpress/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Using the Docker Command Line

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

Step 1: Create a network

$ docker network create wordpress-network

Step 2: Create a volume for MariaDB persistence and create a MariaDB container

$ docker volume create --name mariadb_data
$ docker run -d --name mariadb \
  --env ALLOW_EMPTY_PASSWORD=yes \
  --env MARIADB_USER=bn_wordpress \
  --env MARIADB_PASSWORD=bitnami \
  --env MARIADB_DATABASE=bitnami_wordpress \
  --network wordpress-network \
  --volume mariadb_data:/bitnami/mariadb \
  bitnami/mariadb:latest

Step 3: Create volumes for WordPress persistence and launch the container

$ docker volume create --name wordpress_data
$ docker run -d --name wordpress \
  -p 8080:8080 -p 8443:8443 \
  --env ALLOW_EMPTY_PASSWORD=yes \
  --env WORDPRESS_DATABASE_USER=bn_wordpress \
  --env WORDPRESS_DATABASE_PASSWORD=bitnami \
  --env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
  --network wordpress-network \
  --volume wordpress_data:/bitnami/wordpress \
  bitnami/wordpress:latest

Access your application at http://your-ip/

Persisting your application

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the /bitnami/wordpress path. If the mounted directory is empty, it will be initialized on the first run. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define the Docker volumes named mariadb_data and wordpress_data. The WordPress application state will persist as long as volumes are not removed.

To avoid inadvertent removal of volumes, you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml file present in this repository:

   mariadb:
     ...
     volumes:
-      - 'mariadb_data:/bitnami/mariadb'
+      - /path/to/mariadb-persistence:/bitnami/mariadb
   ...
   wordpress:
     ...
     volumes:
-      - 'wordpress_data:/bitnami/wordpress'
+      - /path/to/wordpress-persistence:/bitnami/wordpress
   ...
-volumes:
-  mariadb_data:
-    driver: local
-  wordpress_data:
-    driver: local

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Mount host directories as data volumes using the Docker command line

Step 1: Create a network (if it does not exist)

$ docker network create wordpress-network

Step 2. Create a MariaDB container with host volume

$ docker run -d --name mariadb \
  --env ALLOW_EMPTY_PASSWORD=yes \
  --env MARIADB_USER=bn_wordpress \
  --env MARIADB_PASSWORD=bitnami \
  --env MARIADB_DATABASE=bitnami_wordpress \
  --network wordpress-network \
  --volume /path/to/mariadb-persistence:/bitnami/mariadb \
  bitnami/mariadb:latest

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Step 3. Create the WordPress container with host volumes

$ docker run -d --name wordpress \
  -p 8080:8080 -p 8443:8443 \
  --env ALLOW_EMPTY_PASSWORD=yes \
  --env WORDPRESS_DATABASE_USER=bn_wordpress \
  --env WORDPRESS_DATABASE_PASSWORD=bitnami \
  --env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
  --network wordpress-network \
  --volume /path/to/wordpress-persistence:/bitnami/wordpress \
  bitnami/wordpress:latest

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Configuration

Environment variables

When you start the WordPress image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. Please note that some variables are only considered when the container is started for the first time. If you want to add a new environment variable:

For docker-compose add the variable name and value under the application section in the docker-compose.yml file present in this repository:

wordpress:
  ...
  environment:
    - WORDPRESS_PASSWORD=my_password
  ...

For manual execution add a --env option with each variable and value:

$ docker run -d --name wordpress -p 80:8080 -p 443:8443 \
  --env WORDPRESS_PASSWORD=my_password \
  --network wordpress-tier \

Examples

SMTP configuration using a Gmail account

This would be an example of SMTP configuration using a Gmail account:

Modify the docker-compose.yml file present in this repository:

   wordpress:
    ...
    environment:
      - WORDPRESS_DATABASE_USER=bn_wordpress
      - WORDPRESS_DATABASE_NAME=bitnami_wordpress
      - ALLOW_EMPTY_PASSWORD=yes
      - WORDPRESS_SMTP_HOST=smtp.gmail.com
      - WORDPRESS_SMTP_PORT=587
      - WORDPRESS_SMTP_USER=your_email@gmail.com
      - WORDPRESS_SMTP_PASSWORD=your_password
  ...

For manual execution:

$ docker run -d --name wordpress -p 80:8080 -p 443:8443 \
  --env WORDPRESS_DATABASE_USER=bn_wordpress \
  --env WORDPRESS_DATABASE_NAME=bitnami_wordpress \
  --env WORDPRESS_SMTP_HOST=smtp.gmail.com \
  --env WORDPRESS_SMTP_PORT=587 \
  --env WORDPRESS_SMTP_USER=your_email@gmail.com \
  --env WORDPRESS_SMTP_PASSWORD=your_password \
  --network wordpress-tier \
  --volume /path/to/wordpress-persistence:/bitnami \
  bitnami/wordpress:latest

Connect WordPress container to an existing database

The Bitnami WordPress container supports connecting the WordPress application to an external database. This would be an example of using an external database for WordPress.

Modify the docker-compose.yml file present in this repository:

    wordpress:
     ...
     environment:
-      - WORDPRESS_DATABASE_HOST=mariadb
+      - WORDPRESS_DATABASE_HOST=mariadb_host
       - WORDPRESS_DATABASE_PORT_NUMBER=3306
       - WORDPRESS_DATABASE_NAME=wordpress_db
       - WORDPRESS_DATABASE_USER=wordpress_user
-      - ALLOW_EMPTY_PASSWORD=yes
+      - WORDPRESS_DATABASE_PASSWORD=wordpress_password
     ...

For manual execution:

$ docker run -d --name wordpress\
  -p 8080:8080 -p 8443:8443 \
  --network wordpress-network \
  --env WORDPRESS_DATABASE_HOST=mariadb_host \
  --env WORDPRESS_DATABASE_PORT_NUMBER=3306 \
  --env WORDPRESS_DATABASE_NAME=wordpress_db \
  --env WORDPRESS_DATABASE_USER=wordpress_user \
  --env WORDPRESS_DATABASE_PASSWORD=wordpress_password \
  --volume wordpress_data:/bitnami/wordpress \
  bitnami/wordpress:latest

In case the database already contains data from a previous WordPress installation, you need to set the variable WORDPRESS_SKIP_BOOTSTRAP to yes. Otherwise, the container would execute the installation wizard and could modify the existing data in the database. Note that, when setting WORDPRESS_SKIP_BOOTSTRAP to yes, values for environment variables such as WORDPRESS_USERNAME, WORDPRESS_PASSWORD or WORDPRESS_EMAIL will be ignored. Make sure that, in this imported database, the table prefix matches the one set in WORDPRESS_TABLE_PREFIX.

WP-CLI tool

The Bitnami WordPress container includes the command line interface wp-cli that can help you to manage and interact with your WP sites. To run this tool, please note you need use the proper system user, daemon.

This would be an example of using wp-cli to display the help menu:

  • Using docker-compose command:
$ docker-compose exec wordpress wp help
  • Using docker command:
$ docker exec wordpress wp help

Find more information about parameters available in the tool in the official documentation.

Logging

The Bitnami WordPress Docker image sends the container logs to stdout. To view the logs:

$ docker logs wordpress

Or using Docker Compose:

$ docker-compose logs wordpress

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Maintenance

Backing up your container

To backup your data, configuration and logs, follow these simple steps:

Step 1: Stop the currently running container

$ docker stop wordpress

Or using Docker Compose:

$ docker-compose stop wordpress

Step 2: Run the backup command

We need to mount two volumes in a container we will use to create the backup: a directory on your host to store the backup in, and the volumes from the container we just stopped so we can access the data.

$ docker run --rm -v /path/to/wordpress-backups:/backups --volumes-from wordpress busybox \
  cp -a /bitnami/wordpress /backups/latest

Restoring a backup

Restoring a backup is as simple as mounting the backup as volumes in the containers.

For the MariaDB database container:

 $ docker run -d --name mariadb \
   ...
-  --volume /path/to/mariadb-persistence:/bitnami/mariadb \
+  --volume /path/to/mariadb-backups/latest:/bitnami/mariadb \
   bitnami/mariadb:latest

For the WordPress container:

 $ docker run -d --name wordpress \
   ...
-  --volume /path/to/wordpress-persistence:/bitnami/wordpress \
+  --volume /path/to/wordpress-backups/latest:/bitnami/wordpress \
   bitnami/wordpress:latest

Upgrade this image

Bitnami provides up-to-date versions of MariaDB and WordPress, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the WordPress container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

The bitnami/wordpress:latest tag always points to the most recent release. To get the most recent release you can simple repull the latest tag from the Docker Hub with docker pull bitnami/wordpress:latest. However it is recommended to use tagged versions.

Step 1: Get the updated image

$ docker pull bitnami/wordpress:latest

Step 2: Stop the running container

Stop the currently running container using the command

$ docker-compose stop wordpress

Step 3: Take a snapshot of the application state

Follow the steps in Backing up your container to take a snapshot of the current application state.

Step 4: Remove the currently running container

Remove the currently running container by executing the following command:

docker-compose rm -v wordpress

Step 5: Run the new image

Update the image tag in docker-compose.yml and re-create your container with the new image:

$ docker-compose up -d

Customize this image

The Bitnami WordPress Docker image is designed to be extended so it can be used as the base image for your custom web applications.

Extend this image

Before extending this image, please note there are certain configuration settings you can modify using the original image:

If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:

FROM bitnami/wordpress
## Put your customizations below
...

Here is an example of extending the image with the following modifications:

  • Install the vim editor
  • Modify the Apache configuration file
  • Modify the ports used by Apache
FROM bitnami/wordpress
LABEL maintainer "Bitnami <containers@bitnami.com>"

## Change user to perform privileged actions
USER 0
## Install 'vim'
RUN install_packages vim
## Revert to the original non-root user
USER 1001

## Enable mod_ratelimit module
RUN sed -i -r 's/#LoadModule ratelimit_module/LoadModule ratelimit_module/' /opt/bitnami/apache/conf/httpd.conf

## Modify the ports used by Apache by default
# It is also possible to change these environment variables at runtime
ENV APACHE_HTTP_PORT_NUMBER=8181
ENV APACHE_HTTPS_PORT_NUMBER=8143
EXPOSE 8181 8143

Based on the extended image, you can update the docker-compose.yml file present in this repository to add other features:

   wordpress:
-    image: bitnami/wordpress:latest
+    build: .
     ports:
-      - '80:8080'
-      - '443:8443'
+      - '80:8181'
+      - '443:8143'
     environment:
+      - PHP_MEMORY_LIMIT=512m
     ...

Notable Changes

5.7.1-debian-10-r21

  • The size of the container image has been decreased.
  • The configuration logic is now based on Bash scripts in the rootfs/ folder.
  • Multisite support was added via WORDPRESS_ENABLE_MULTISITE and related environment variables.
  • Plugins can be installed and activated on the first deployment via WORDPRESS_PLUGINS.
  • Added support for limiting auto-updates to WordPress core via WORDPRESS_AUTO_UPDATE_LEVEL. In addition, auto-updates have been disabled by default. To update WordPress core, we recommend to swap the container image version for your deployment instead of using the built-in update functionality.
  • This image now supports connecting to MySQL and MariaDB databases securely via SSL.

5.3.2-debian-10-r30

  • The WordPress container has been migrated to a "non-root" user approach. Previously the container ran as the root user and the Apache daemon was started as the daemon user. From now on, both the container and the Apache daemon run as user 1001. You can revert this behavior by changing USER 1001 to USER root in the Dockerfile.
  • Consequences:
    • The HTTP/HTTPS ports exposed by the container are now 8080/8443 instead of 80/443.
    • Backwards compatibility is not guaranteed when data is persisted using docker or docker-compose. We highly recommend migrating the WP site by exporting its content, and importing it on a new WordPress container. In the links below you'll find some alternatives:
    • No writing permissions will be granted on wp-config.php by default.

5.2.1-debian-9-r9 and 5.2.1-ol-7-r9

  • This image has been adapted so it's easier to customize. See the Customize this image section for more information.
  • The Apache configuration volume (/bitnami/apache) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the Apache configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom Apache configuration files are advised to mount a volume for the configuration at /opt/bitnami/apache/conf, or mount specific configuration files individually.
  • The PHP configuration volume (/bitnami/php) has been deprecated, and support for this feature will be dropped in the near future. Until then, the container will enable the PHP configuration from that volume if it exists. By default, and if the configuration volume does not exist, the configuration files will be regenerated each time the container is created. Users wanting to apply custom PHP configuration files are advised to mount a volume for the configuration at /opt/bitnami/php/conf, or mount specific configuration files individually.
  • Enabling custom Apache certificates by placing them at /opt/bitnami/apache/certs has been deprecated, and support for this functionality will be dropped in the near future. Users wanting to enable custom certificates are advised to mount their certificate files on top of the preconfigured ones at /certs.

5.1.1-r28, 5.1.1-rhel-7-r31 and 5.1.1-ol-7-r30

  • Users reported that they wanted to import their WordPress database from other installations, such as this ticket. Now, in order to cover this use case, the variable WORDPRESS_SKIP_INSTALL can be set to avoid the container launch the WordPress installation wizard.

5.0.3-r20

  • For performance and security reasons, Apache will set the AllowOverride directive to None by default. This means that, instead of using .htaccess files, all the default directives will be moved to the /opt/bitnami/wordpress/wordpress-htaccess.conf file. The only downside of this is the compatibility with certain plugins, which would require changes in that file (you would need to mount a modified version of wordpress-htaccess.conf compatible with these plugins). If you want to have the default .htaccess behavior, set the WORDPRESS_HTACCESS_OVERRIDE_NONE env var to no.

5.0.0-r0

  • wp-cli tool is included in the Docker image. Find it at /opt/bitnami/wp-cli/bin/wp.

In addition, the syntax is rendered while editing to clearly show the expected result. Headings are larger, emphasized words are italicized, links are underlined, etc.

EasyMDE also features both built-in auto saving and spell checking. The editor is entirely customizable, from theming to toolbar buttons and javascript hooks.

  • imageUploadFunction: A custom function for handling the image upload. Using this function will render the options imageMaxSize, imageAccept, imageUploadEndpoint and imageCSRFToken ineffective.
    • The function gets a file and onSuccess and onError callback functions as parameters. onSuccess(imageUrl: string) and onError(errorMessage: string)
  • imageUploadEndpoint: The endpoint where the images data will be sent, via an asynchronous POST request. The server is supposed to save this image, and return a JSON response.

    • sbInit: Status message displayed initially if uploadImage is set to true. Defaults to Attach files by drag and dropping or pasting from clipboard..
    • sbOnDragEnter: Status message displayed when the user drags a file to the text area. Defaults to Drop image to upload it..
    • sbOnDrop: Status message displayed when the user drops a file in the text area. Defaults to Uploading images #images_names#.
    • sbProgress: Status message displayed to show uploading progress. Defaults to Uploading #file_name#: #progress#%.
    • sbOnUploaded: Status message displayed when the image has been uploaded. Defaults to Uploaded #image_name#.
    • sizeUnits: A comma-separated list of units used to display messages with human-readable file sizes. Defaults to B, KB, MB (example: 218 KB). You can use B,KB,MB instead if you prefer without whitespaces (218KB).
  • errorMessages: Errors displayed to the user, using the errorCallback option, where #image_name#, #image_size# and #image_max_size# will replaced by their respective values, that can be used for customization or internationalization:
    • noFileGiven: The server did not receive any file from the user. Defaults to You must select a file..
    • typeNotAllowed: The user send a file type which doesn't match the imageAccept list, or the server returned this error code. Defaults to This image type is not allowed..
    • fileTooLarge: The size of the image being imported is bigger than the imageMaxSize, or if the server returned this error code. Defaults to Image #image_name# is too big (#image_size#).\nMaximum file size is #image_max_size#..

  • errorCallback: A callback function used to define how to display an error message. Defaults to (errorMessage) => alert(errorMessage).
  • renderingConfig: Adjust settings for parsing the Markdown during previewing (not editing).
    • codeSyntaxHighlighting: If set to true, will highlight using highlight.js. Defaults to false. To use this feature you must include highlight.js on your page or pass in using the hljs option. For example, include the script and the CSS files like:
      <script src="https://cdn.jsdelivr.net/highlight.js/latest/highlight.min.js"></script>
      <link rel="stylesheet" href="https://cdn.jsdelivr.net/highlight.js/latest/styles/github.min.css">
    • hljs: An injectible instance of highlight.js. If you don't want to rely on the global namespace (window.hljs), you can provide an instance here. Defaults to undefined.
    • markedOptions: Set the internal Markdown renderer's options. Other renderingConfig options will take precedence.

    toolbar: false,
    toolbarTips: false,
});

Toolbar icons

Below are the built-in toolbar icons (only some of which are enabled by default), which can be reorganized however you like. "Name" is the name of the icon, referenced in the JavaScript. "Action" is either a function or a URL to open. "Class" is the class given to the icon. "Tooltip" is the small tooltip that appears via the title="" attribute. Note that shortcut hints are added automatically and reflect the specified action if it has a key bind assigned to it (i.e. with the value of action set to bold and that of tooltip set to Bold, the final text the user will see would be "Bold (Ctrl-B)").

Additionally, you can add a separator between any icons by adding "|" to the toolbar array.

Toolbar customization

Customize the toolbar using the toolbar option.

Only the order of existing buttons:

const easyMDE = new EasyMDE({
    toolbar: ["bold", "italic", "heading", "|", "quote"]
});

All information and/or add your own icons

const easyMDE = new EasyMDE({
    toolbar: [
        {
            name: "bold",
            action: EasyMDE.toggleBold,
            className: "fa fa-bold",
            title: "Bold",
        },
        "italics", // shortcut to pre-made button
        {
            name: "custom",
            action: (editor) => {
                // Add your own code
            },
            className: "fa fa-star",
            title: "Custom Button",
            attributes: { // for custom attributes
                id: "custom-id",
                "data-value": "custom value" // HTML5 data-* attributes need to be enclosed in quotation marks ("") because of the dash (-) in its name.
            }
        },
        "|" // Separator
        // [, ...]
    ]
});

Put some buttons on dropdown menu

const easyMDE = new EasyMDE({
    toolbar: [{
                name: "heading",
                action: EasyMDE.toggleHeadingSmaller,
                className: "fa fa-header",
                title: "Headers",
            },
            "|",
            {
                name: "others",
                className: "fa fa-blind",
                title: "others buttons",
                children: [
                    {
                        name: "image",
                        action: EasyMDE.drawImage,
                        className: "fa fa-picture-o",
                        title: "Image",
                    },
                    {
                        name: "quote",
                        action: EasyMDE.toggleBlockquote,
                        className: "fa fa-percent",
                        title: "Quote",
                    },
                    {
                        name: "link",
                        action: EasyMDE.drawLink,
                        className: "fa fa-link",
                        title: "Link",
                    }
                ]
            },
        // [, ...]
    ]
});

Keyboard shortcuts

EasyMDE comes with an array of predefined keyboard shortcuts, but they can be altered with a configuration option. The list of default ones is as follows:

Shortcut (Windows / Linux)Shortcut (macOS)Action
Ctrl-'Cmd-'"toggleBlockquote"
Ctrl-BCmd-B"toggleBold"
Ctrl-ECmd-E"cleanBlock"
Ctrl-HCmd-H"toggleHeadingSmaller"
Ctrl-ICmd-I"toggleItalic"
Ctrl-KCmd-K"drawLink"
Ctrl-LCmd-L"toggleUnorderedList"
Ctrl-PCmd-P"togglePreview"
Ctrl-Alt-CCmd-Alt-C"toggleCodeBlock"
Ctrl-Alt-ICmd-Alt-I"drawImage"
Ctrl-Alt-LCmd-Alt-L"toggleOrderedList"
Shift-Ctrl-HShift-Cmd-H"toggleHeadingBigger"
F9F9"toggleSideBySide"
F11F11"toggleFullScreen"

Here is how you can change a few, while leaving others untouched:

const editor = new EasyMDE({
    shortcuts: {
        "toggleOrderedList": "Ctrl-Alt-K", // alter the shortcut for toggleOrderedList
        "toggleCodeBlock": null, // unbind Ctrl-Alt-C
        "drawTable": "Cmd-Alt-T", // bind Cmd-Alt-T to drawTable action, which doesn't come with a default shortcut
    }
});

Shortcuts are automatically converted between platforms. If you define a shortcut as "Cmd-B", on PC that shortcut will be changed to "Ctrl-B". Conversely, a shortcut defined as "Ctrl-B" will become "Cmd-B" for Mac users.

The list of actions that can be bound is the same as the list of built-in actions available for toolbar buttons.

Advanced use

Event handling

You can catch the following list of events: https://codemirror.net/doc/manual.html#events

const easyMDE = new EasyMDE();
easyMDE.codemirror.on("change", () => {
    console.log(easyMDE.value());
});

Removing EasyMDE from text area

You can revert to the initial text area by calling the toTextArea method. Note that this clears up the autosave (if enabled) associated with it. The text area will retain any text from the destroyed EasyMDE instance.

const easyMDE = new EasyMDE();
// ...
easyMDE.toTextArea();
easyMDE = null;

If you need to remove registered event listeners (when the editor is not needed anymore), call easyMDE.cleanup().

Useful methods

The following self-explanatory methods may be of use while developing with EasyMDE.

const easyMDE = new EasyMDE();
easyMDE.isPreviewActive(); // returns boolean
easyMDE.isSideBySideActive(); // returns boolean
easyMDE.isFullscreenActive(); // returns boolean
easyMDE.clearAutosavedValue(); // no returned value

How it works

EasyMDE is a continuation of SimpleMDE.

SimpleMDE began as an improvement of lepture's Editor project, but has now taken on an identity of its own. It is bundled with CodeMirror and depends on Font Awesome.

CodeMirror is the backbone of the project and parses much of the Markdown syntax as it's being written. This allows us to add styles to the Markdown that's being written. Additionally, a toolbar and status bar have been added to the top and bottom, respectively. Previews are rendered by Marked using GitHub Flavored Markdown (GFM).

SimpleMDE fork

I originally made this fork to implement FontAwesome 5 compatibility into SimpleMDE. When that was done I submitted a pull request, which has not been accepted yet. This, and the project being inactive since May 2017, triggered me to make more changes and try to put new life into the project.

Changes include:

  • FontAwesome 5 compatibility
  • Guide button works when editor is in preview mode
  • Links are now https:// by default
  • Small styling changes
  • Support for Node 8 and beyond
  • Lots of refactored code
  • Links in preview will open in a new tab by default
  • TypeScript support

My intention is to continue development on this project, improving it and keeping it alive.

Hacking EasyMDE

You may want to edit this library to adapt its behavior to your needs. This can be done in some quick steps:

  1. Follow the prerequisites and installation instructions in the contribution guide;
  2. Do your changes;
  3. Run gulp command, which will generate files: dist/easymde.min.css and dist/easymde.min.js;
  4. Copy-paste those files to your code base, and you are done.

Docker manifest - A peek into image's manifest.json files

docker manifest – An experimental feature !

The image manifest provides a configuration and a set of layers for a container image.

This is an experimental feature. To enable this feature in the Docker CLI, one can edit the config.json file found in ~/.docker/config.json like :

{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "XXXXXXX"
                }
        },
        "HttpHeaders": {
                "User-Agent": "Docker-Client/19.03.8 (linux)"
        },
        "experimental": "enabled",
        "debug": true
}

What is ‘docker manifest’ ?

The docker manifest command does not work independently to perform any action. In order to work with the docker manifest or manifest list, we use sub-commands along with it. This manifest sub-command can enable us to interact with the image manifests. Furthermore, it also gives information about the OS and the architecture, that a particular image was built for.

A single manifest comprises of information about an image, it’s size, the layers and digest.

A manifest list is a list of image layers (manifests) that are, created by specifying one or more image names. It can then be used in the same way as an image name in docker pull and docker run commands.

Commands to get started with :

After enabling this feature, one would be able to access the following command :

docker-manifest-enter image description here

These commands are easy to use. It basically avoids the need for pulling and running and then testing the images locally, from a docker registry.

Next, to inspect an image manifest, follow this syntax,

 docker manifest inspect image-name

enter image description here
