So, we have a deployed Kubernetes cluster — see the Terraform: Creating EKS, Part 1 — VPCs, Subnets, and Endpoints series.
And we have a GitHub Actions workflow to deploy it — see GitHub Actions: Deploying Dev/Prod environments with Terraform.
It’s time to start deploying our backend to Kubernetes.
Here we will use GitHub Actions again — we will build a Docker image with our Backend API service, store it in AWS Elastic Container Service, and then deploy a Helm chart to which we will pass a new Docker Tag in values.
For now, we have only one working environment, Dev, but later we will add Staging and Production. In addition, we need to be able to deploy a feature environment to the same Dev EKS, but with custom values for some variables.
However, we will now do it in the test repository "atlas-test" and with the test Helm chart.
