Part 3: CI CD pipeline with MuleSoft and GitHub Actions MUnit testing

Some teams practicing continuous deployment elect to deploy daily or even hourly to production, though continuous deployment isn’t optimal for every business application. Here’s how software development teams automate continuous integration and delivery all the way through the CI/CD pipeline. In a traditional software development process, multiple developers would produce code, and only towards the end of the release, integrate their work together. This introduced many bugs and issues, which were identified and resolved after a long testing stage.

Now in the launch instance configurations page, give your instance a name. I have a Githubrepository you can use as a guide for this tutorial. In this section, we are going over how to set up a CI/CD pipeline in AWS for a django project. Once the build phase is over, then you move on to thetesting phase. In this phase, we have various kinds of testing, one of them is the unit test(where you test the chunk/unit of software or for its sanity test). There are four stages of a CI/CD pipeline 1) Source Stage, 2) Build Stage, 3) Test Stage, 4) Deploy Stage.

This not only makes the merging of code very difficult, prone to conflicts, and time-consuming but also results in bugs accumulating for a long time which are only identified in later stages of development. These factors make it harder to deliver updates to customers quickly. It used to be that software development was simply about, well, software development.

A continuous integration/continuous delivery (CI/CD) pipeline is a framework that emphasizes iterative, reliable code delivery processes for agile DevOps teams. It involves a workflow encompassing continuous integration, testing, delivery, and continuous delivery/deployment practices. The pipeline arranges these methods into a unified process for developing high-quality software. Continuous deployment may sound synonymous with continuous delivery — and both are often referred to by the abbreviation “CD” — but it is a separate practice. Because it doesn’t require any pause for human mediation, this final stage is known as continuous deployment.

Next, for the service role, select the New Service Role option. We will need to connect to our Github account first, after that we can choose which repository we want to pick from with its branch. We should now be moved to the CodeBuild page CI CD pipeline where we can create our first build. There are guides on how to do this on the Connect page, click on the Connect button in the top right corner of the instance page. Next, we need to reboot our instance for the changes to take effect.

• You will have a set of developers who are responsible for writing the code which will further go on and build the web application.
• Should your team feel unsure about implementing the entire CI/CD pipeline in one shot, phase it in with two stages.
• Unplanned downtime – CI/CD pipelines can fail, delaying releases and hurting developer productivity.
• One particularly frustrating scenario is an automated update that switches on and forces a new version update on a critical process.
• Multi-project pipeline graphs help you visualize the entire pipeline, including all cross-project inter-dependencies.
• Some popular CD tools are AWS CodeDeploy, Jenkins, and GitLab.

In this post, we’ll see the steps to create a pipeline with GitHub Actions that will run the MUnit tests you have set up in your Mule project. Executing any steps required to restart services or call service endpoints needed for new code pushes. Codefresh workflows redefine the way pipelines are created by bringing GitOps into the mix and adopting a Git-based process instead of the usual ClickOps.

Based on the status of the step, the server then notifies the concerned developer whether the integration of the new code to the existing code base was a success or a failure. CI or Continuous Integration is the practice of automating the integration of code changes from multiple developers into a single codebase. It is a software development practice where the developers commit their work frequently into the central code repository . Then there are automated tools that build the newly committed code and do a code review, etc as required upon integration. There are plenty of existing services and open-source software that your team can glue together to create your own CI/CD pipeline. Recall that one key motivation for having a CI/CD pipeline is to make integration and deployment work boring and reliable, thus freeing up developer resources for more important work.

These declarative configurations become the basis of the CI/CD process and are used to create all environments—dev, test, and production. One particularly frustrating scenario is an automated update that switches on and forces a new version update on a critical process. In addition to interrupting the process, the new version might present compatibility issues for the existing CI/CD pipeline. The teams then have to restructure the overall CI/CD deployment process to support the new version. Cost reduction—teams spend less time on manual tasks such as testing, deployment, and infrastructure maintenance. CI/CD practices help identify flaws early in the SDLC, making them easier to fix.

Of course, ideally, this code has been built and tested successfully by the CI server too. CI allows developers to work independently, creating their own coding “branch” to implement small changes. As the developer works, they can take snapshots of the source code, typically within a versioning tool like Git. The developer is free to work on new features; if a problem comes up, Git can easily revert the codebase to its previous state. Once the development team has selected a CI/CD tool, it must ensure that all environment variables are configured outside the application. CI/CD tools allow development teams to set these variables, mask variables such as passwords and account keys, and configure them at the time of deployment for the target environment.

It addresses the problem of overloading operations teams with manual processes that slow down app delivery. It builds on the benefits of continuous delivery by automating the next stage in the pipeline. Continuous integration/continuous delivery, known as CI/CD, is a set of processes that help software development teams deliver code changes more frequently and reliably. CI/CD is part of DevOps, which helps shorten the software development lifecycle.

After creating our deployment application, we will be navigated to the deployment group page, where we will create a new deployment group for our deployment application. When we check our build projects, we should see our newly created build project. We need to describe the environment in which are builds and tests are going to be carried out. In our root working directory, create a file called buildspec.yml and add this block of code to it. With our instance provisioned, we will now install the codedeploy-agent on our server.

The right way to create a dashboard is to first perform an assessment of the data that everyone wants and needs, and how they want it to look. For example, teams need to decide whether and how to use numbers, graphs, and colors to indicate status. Provide input on what will and won’t work, then test and retest the plan.

Continuous delivery tools also provide dashboard and reporting functions, which are enhanced when devops teams implement observable CI/CD pipelines. The dashboard and reporting functions integrate with version control and agile tools to help developers determine what code changes and user stories made up the build. Testing—developers use automated tests to validate the performance and correctness of their code.

At every stage of the pipeline, the development team receives alerts to errors so they can immediately address the issue. The code changes go through the pipeline again, so only error-free code is deployed to production. This is the process of delivering the build to a run time environment for integration, quality assurance, or preproduction. In this phase, functional and performance tests are run against the application. In this first phase, developers merge their code changes with primary code repositories for their projects.

Set up your build.yml

A practical guide to the continuous integration/continuous delivery (CI/CD) pipeline.. Continuous testingbegins when you produce a continuous integration build and a package . Below is a pictorial representation of a CI pipeline- the workflow from developers checking in their code to its automated build, test, and final notification of the build status. Recall I mentioned that many of the CI and CD steps are highly repetitive. By automating the process and delegating that to a CI/CD pipeline, you not only free up precious developer resources for actual product development tasks but you also reduce the chances of error.

Taken together, all of these connected CI/CD practices make deployment of an application less risky, whereby it’s easier to release changes to apps in small pieces, rather than all at once. There’s also a lot of upfront investment, though, since automated tests will need to be written to accommodate a variety of testing and release stages in the CI/CD pipeline. It’s an answer to the problem of poor visibility and communication between dev and business teams. To that end, the purpose of continuous delivery is to ensure that it takes minimal effort to deploy new code. Organizations that build CI/CD pipelines can push out code faster.

Advantages of CI/CD pipelines

Many teams operating CI/CD pipelines in cloud environments also use containers such as Docker and orchestration systems such asKubernetes. Containers allow for packaging and shipping applications in a standard, portable way. Containers make it easy to scale up or tear down environments with variable workloads. Continuous integration not only packages all the software and database components, but the automation will also execute unit tests and other types of tests.

Continuous Integration and Continuous Deployment are software development practices that involve continuously building, testing, and deploying software changes. If your team hasn’t implemented a proper CI/CD pipeline yet, your next step is to plan for it. Talk with your architect and project manager and establish a code-freeze week to set up this pipeline. Should your team feel unsure about implementing the entire CI/CD pipeline in one shot, phase it in with two stages. My advice is to implement CI first, as that sets the foundation for CD. You’ll also want to measure your team’s velocity in delivering software requirements before and after these changes go live.

When the test is completed, you move on to the deploy phase, where you deploy it into a staging or a test server. Here, you can view the code or you can view the app in a simulator. Visit the Getting Started Resource Center to find tutorials, projects and videos to get started with AWS.
