API’s from Dev to Production — Part 3
Welcome to Part 3 of this blog series that will go from the most basic example of a .net 5 webapi in C#, and the journey from development to production with a shift-left mindset. We will use Azure, Docker, GitHub, GitHub Actions for CI/C-Deployment and Infrastructure as Code using Pulumi.
In this post we will be looking at:
- GitHub Actions:
- Build the docker image
- Publish the docker image to the GitHub Container Registry
TL;DR
Instead of building locally like we did previously, we utilised GitHub Actions and the GitHub Container Registry to store our Docker image. GitHub Actions workflow is basic YAML, and we used a few actions to achieve what we needed. We checked-out the repository, docker build, logged into our GitHub Container Registry and executed a docker push command. We used a Personal Access token and stored it in GitHub secrets to use in our workflow, and finally, we pulled down our public image from the GitHub Container Registry and tested locally using Postman.
Requirements
We will be picking-up where we left off in Part 2, which means you’ll need the end-result from GitHub Repo from — Part 2 to start with.
What are GitHub Actions?
GitHub Actions makes it easy to automate all kinds of software workflows, right inside GitHub. You can build, test, and deploy your code and more. Workflows can be triggered off many GitHub events like push, issue creation and more. There is support for Linux, macOS, Windows, ARM and of course containers Even matrix builds — so you can build the same software across multiple OS’s. There are live logs, secret store and more, plus the UX is rather nice too! All of this is driven by YAML files, nice and neat, and stored under source control management.
There is also GitHub Packages which has various package management providers like npm, nuget and more. For containers, there is a new GitHub Container Registry, so images no longer need to be stored in GitHub Packages but there is a real container registry — We will use this in this blog post :D
