Ansible Container Project That Manages The Lifecycle Of AWX on Docker

AWX (Built with Ansible Container)

DEPRECATED: This project has been deprecated. Please use the official AWX containers and docker-compose.yml file to run AWX instead.

This project is in its early stages. There will be bugs!

This project is composed of three main parts:

  • Ansible Container project: This project is maintained on GitHub: geerlingguy/awx-container. Please file issues, support requests, etc. against this GitHub repository.
  • Docker Hub Image: If you just want to use geerlingguy/awx_web and geerlingguy/awx_task in your project, you can pull it from Docker Hub.
  • Ansible Role: If you need an Ansible role to build AWX, check out geerlingguy.awx on Ansible Galaxy. (This is the Ansible role that does the bulk of the work in managing the AWX container.)

Versions

Currently maintained versions include:

  • geerlingguy/awx_web:
    • 1.x, latest: AWX 1.x
    • 1.0.5
  • geerlingguy/awx_task:
    • 1.x, latest: AWX 1.x
    • 1.0.5

Quickstart - Standalone Usage with Docker Compose

If you just want to get an AWX environment running quickly, you can use the docker-compose.yml file included with this project to build a local environment accessible on http://localhost:80/:

mkdir awx-test && cd awx-test
curl -O https://raw.githubusercontent.com/geerlingguy/awx-container/master/docker-compose.yml
docker-compose up -d

The Docker Compose file uses community images for postgres, rabbitmq, and memcached, and the following images for AWX:

After the initial database migration completes (this can take a few minutes; follow the progress with docker logs -f [id-of-awx_task-container]), you will be able to access the AWX interface at http://localhost/. The default login is admin/password.

Note: Switch the image for the awx_web and awx_task containers in docker-compose.yml if you want to use the geerlingguy/ maintained images rather than the ones from ansible/. If you're just kicking AWX's tires though, stick with the defaults.

Management with Ansible Container

Prerequisites

Before using this project to build and maintain AWX images for Docker, you need to have the following installed:

Build the AWX images

Typically, you would build the images as specified in the container.yml file using ansible-container --var-file config.yml build, but in this case, since there are many dependencies bundled in the AWX repository, we will build the Docker images using a helper playbook:

$ cd prebuild/
$ ansible-galaxy install -r requirements.yml --force
$ ansible-playbook -i 'localhost,' -c local prebuild.yml

After this playbook runs, you should see two new Docker images (which we'll use in the Ansible Container definition):

$ docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
awx_task            devel               26311794058d        29 seconds ago      938MB
awx_web             devel               3d38dccc9190        58 seconds ago      913MB

A Vagrantfile is included with this project to assist in building a clean environment with all the dependencies required to build the AWX images (in case you don't want to install everything on your local workstation!). To use it:

  1. Run vagrant up.
  2. Wait for Vagrant's provisioning to complete (it will run prebuild.yml automatically).
  3. Log in with vagrant ssh and use docker or ansible as needed.

Build the conductor

Build the conductor using ansible-container build:

ansible-container --var-file config.yml build

Note: If you get any permission errors trying to generate a Docker container, make sure you're either running the commands as root or with sudo, or your user is in the docker group (e.g. sudo usermod -G docker -a [user], then log out and log back in).

Run the containers

ansible-container --var-file config.yml run

You should be able to reach AWX by accessing http://localhost/ in your browser.

(Use stop to stop the container, and destroy to reset the containers and all images.)

Push the containers to Docker Hub

Currently, the process for updating this image on Docker Hub is manual. Eventually this will be automated via Travis CI using ansible-container push (currently, this is waiting on this issue to be resolved).

Log into Docker Hub on the command line:

docker login --username=geerlingguy

Tag the latest version (only if this is the latest/default version):

docker tag awx_web:devel geerlingguy/awx_web:latest
docker tag awx_web:devel geerlingguy/awx_web:1.x
docker tag awx_task:devel geerlingguy/awx_task:latest
docker tag awx_task:devel geerlingguy/awx_task:1.x

Push tags to Docker Hub:

docker push geerlingguy/awx_web:latest # (if this was just tagged)
docker push geerlingguy/awx_web:1.x
[etc...]

Top Android Projects with Source Code

Android Projects with Source Code – Your entry pass into the world of Android

Hello Everyone, welcome to this article, which is going to be really important to all those who’re in dilemma for their projects and the project submissions. This article is also going to help you if you’re an enthusiast looking forward to explore and enhance your Android skills. The reason is that we’re here to provide you the best ideas of Android Project with source code that you can choose as per your choice.

These project ideas are simple suggestions to help you deal with the difficulty of choosing the correct projects. In this article, we’ll see the project ideas from beginners level and later we’ll move on to intermediate to advance.

top android projects with source code

Android Projects with Source Code

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project

Android Projects for beginners

1. Calculator

build a simple calculator app in android studio source code

Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.

To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.

Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.

Source Code: Simple Calculator Project

2. A Reminder App

Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.

To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.

In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.

3. Quiz Application

Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.

To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.

In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.

4. Simple Tic-Tac-Toe

android project tic tac toe game app

Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.

To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.

Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.

Source Code: Tic Tac Toe Game Project

5. Stopwatch

Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.

This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.

6. To Do App

Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.

So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.

Now for users, they will sign up and get access to the write section. Here the users can note down the things and store them permanently. Users can also alter the data or delete them. Finally, they can logout and also, login again and again whenever they like.

7. Roman to decimal converter

Android Project: This app is aimed at the conversion of Roman numbers to their significant decimal number. It’ll help to check the meaning of the roman numbers. Moreover, it will be easy to develop and will help you get your hands on coding and Android.

You need to use Android Studio, Java for coding and XML for interface. The application will take input from the users and convert them to decimal. Once it converts the Roman no. into decimal, it will show the results on the screen.

The users are supposed to just enter the Roman Number and they’ll get the decimal values on the screen. This can be a good android project for final year students.

8. Virtual Dice Roller

Android Project: Well, coming to this part that is Virtual Dice or a random no. generator. It is another simple but interesting app for computer science students. The only task that it would need to do would be to generate a number randomly. This can help people who’re often confused between two or more things.

Using a simple random number generator you can actually create something as good as this. All you’d need to do is get you hands-on OnClick listeners. And a good layout would be cherry on the cake.

The user’s task would be to set the range of the numbers and then click on the roll button. And the app will show them a randomly generated number. Isn’t it interesting ? Try soon!

9. A Scientific Calculator App

Android Project: This application is very important for you as a beginner as it will let you use your logical thinking and improve your programming skills. This is a scientific calculator that will help the users to do various calculations at ease.

To make this application you’d need to use Android Studio. Here you’d need to use arithmetic logics for the calculations. The user would need to give input to the application that will be in terms of numbers. After that, the user will give the operator as an input. Then the Application will calculate and generate the result on the user screen.

10. SMS App

Android Project: An SMS app is another easy but effective idea. It will let you send the SMS to various no. just in the same way as you use the default messaging application in your phone. This project will help you with better understanding of SMSManager in Android.

For this application, you would need to implement Java class SMSManager in Android. For the Layout you can use XML or JSON. Implementing SMSManager into the app is an easy task, so you would love this.

The user would be provided with the facility to text to whichever number they wish also, they’d be able to choose the numbers from the contact list. Another thing would be the Textbox, where they’ll enter their message. Once the message is entered they can happily click on the send button.

10 Writing steps to create a good project brief - Mobile app development

Developing a mobile application can often be more challenging than it seems at first glance. Whether you’re a developer, UI designer, project lead or CEO of a mobile-based startup, writing good project briefs prior to development is pivotal. According to Tech Jury, 87% of smartphone users spend time exclusively on mobile apps, with 18-24-year-olds spending 66% of total digital time on mobile apps. Of that, 89% of the time is spent on just 18 apps depending on individual users’ preferences, making proper app planning crucial for success.

Today’s audiences know what they want and don’t want in their mobile apps, encouraging teams to carefully write their project plans before they approach development. But how do you properly write a mobile app development brief without sacrificing your vision and staying within the initial budget? Why should you do so in the first place? Let’s discuss that and more in greater detail.

Why a Good Mobile App Project Brief Matters?

Why-a-Good-Mobile-App-Project-Brief-Matters

It’s worth discussing the significance of mobile app project briefs before we tackle the writing process itself. In practice, a project brief is used as a reference tool for developers to remain focused on the client’s deliverables. Approaching the development process without written and approved documentation can lead to drastic, last-minute changes, misunderstanding, as well as a loss of resources and brand reputation.

For example, developing a mobile app that filters restaurants based on food type, such as Happy Cow, means that developers should stay focused on it. Knowing that such and such features, UI elements, and API are necessary will help team members collaborate better in order to meet certain expectations. Whether you develop an app under your brand’s banner or outsource coding and design services to would-be clients, briefs can provide you with several benefits:

  • Clarity on what your mobile app project “is” and “isn’t” early in development
  • Point of reference for developers, project leads, and clients throughout the cycle
  • Smart allocation of available time and resources based on objective development criteria
  • Streamlined project data storage for further app updates and iterations

Writing Steps to Create a Good Mobile App Project Brief

Writing-Steps-to-Create-a-Good-Mobile-App-Project-Brief

1. Establish the “You” Behind the App

Depending on how “open” your project is to the public, you will want to write a detailed section about who the developers are. Elements such as company name, address, project lead, project title, as well as contact information, should be included in this introductory segment. Regardless of whether you build an in-house app or outsource developers to a client, this section is used for easy document storage and access.

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.
