How To Deploy Containers to Azure ACI using Docker CLI and Compose

Running containers in the cloud can be hard and confusing. There are so many options to choose from and then understanding how all the different clouds work from virtual networks to security. Not to mention orchestrators. It’s a learning curve to say the least.

At Docker we are making the Developer Experience (DX) more simple. As an extension of that we want to provide the same beloved Docker experience that developers use daily and integrate it with the cloud. Microsoft’s Azure ACI provided an awesome platform to do just that.

In this tutorial, we take a look at running single containers and multiple containers with Compose in Azure ACI. We’ll walk you through setting up your docker context and even simplifying logging into Azure. At the end of this tutorial, you will be able to use familiar Docker commands to deploy your applications into your own Azure ACI account.

Prerequisites

To complete this tutorial, you will need:

• Docker installed on your development machine. You can download and install Docker Desktop Edge version 2.3.3.0 or later from the links below:
• Docker Desktop for Mac
• Docker Desktop for Windows
• Docker Hub account. Get your free account here.
• An Azure account. Sign up for free.
• Git installed on your development machine.
• An IDE or text editor to use for editing files. I would recommend VSCode

Run Docker Container on ACI

The integration with Azure ACI is very similar to working with local containers. The development teams have thought very deeply about the developer experience and have tried to make the UX for working with ACI as close as possible to working with local containers.

Let’s run a simple Nginx web server on Azure ACI.

Log into Azure

You do not need to have the Azure CLI installed on your machine to run Docker images in ACI. Docker takes care of everything.

The first thing you need to do is to login to Azure.

$ docker login azure

This will open a browser window which will allow you to login to Azure.

Select your account and login. Once you are logged in, you can close the browser window.

Running Azure Functions in a Docker Container

Azure Functions let us execute our code in a serverless environment. This does not require to create a solution or publish it as Azure Apps. In short, just focus on code and your functional aspect, and don’t need to worry about infrastructure.

#azure #azure function #docker #container

Docker Tutorial for Beginners 8 - Build and Run C++ Applications in a Docker Container

Docker is an open platform that allows use package, develop, run, and ship software applications in different environments using containers.
In this course We will learn How to Write Dockerfiles, Working with the Docker Toolbox, How to Work with the Docker Machine, How to Use Docker Compose to fire up multiple containers, How to Work with Docker Kinematic, Push images to Docker Hub, Pull images from a Docker Registery, Push stacks of servers to Docker Hub.
How to install Docker on Mac.

Ever Wondered Why We Use Containers In DevOps?

At some point we’ve all said the words, “But it works on my machine.” It usually happens during testing or when you’re trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.

Every machine has different underlying states depending on the operating system, other installed programs, and permissions. Getting a project to run locally could take hours or even days because of weird system issues.

The worst part is that this can also happen in production. If the server is configured differently than what you’re running locally, your changes might not work as you expect and cause problems for users. There’s a way around all of these common issues using containers.

What is a container

A container is a piece of software that packages code and its dependencies so that the application can run in any computing environment. They basically create a little unit that you can put on any operating system and reliably and consistently run the application. You don’t have to worry about any of those underlying system issues creeping in later.

Although containers were already used in Linux for years, they became more popular in recent years. Most of the time when people are talking about containers, they’re referring to Docker containers. These containers are built from images that include all of the dependencies needed to run an application.

When you think of containers, virtual machines might also come to mind. They are very similar, but the big difference is that containers virtualize the operating system instead of the hardware. That’s what makes them so easy to run on all of the operating systems consistently.

What containers have to do with DevOps

Since we know how odd happenings occur when you move code from one computing environment to another, this is also a common issue with moving code to the different environments in our DevOps process. You don’t want to have to deal with system differences between staging and production. That would require more work than it should.

Once you have an artifact built, you should be able to use it in any environment from local to production. That’s the reason we use containers in DevOps. It’s also invaluable when you’re working with microservices. Docker containers used with something like Kubernetes will make it easier for you to handle larger systems with more moving pieces.

What to do if a Docker container immediately exits

If you run a container using docker run and it immediately exits and every time you press the Start button in Docker Desktop it exits again, there is a problem.

The way to figure out what is wrong is to run docker logs, adding the name of the container at the end:

You can also click the Container name in Docker Desktop, and it will show a list of logs:

#docker #container #docker desktop #docker run
