I have setup a kubernetes cluster on AWS using kops.
I am trying to automate deployment with github actions.
name: Build and Deploy
on:
push:
branches:
- develop
jobs:
build_docker_image:
- uses: actions/checkout@v2
- name: Build the tagged Docker image
run: docker build --target dev -t org/customer-service-backend:la
push_docker_image_to_github-packages:
- uses: docker/build-push-action@v2
with:
username: ${{ github.actor }}
password: ${{ secrets.GITHUB_TOKEN }}
registry: docker.pkg.github.com
repository: org/customer-service-backend:latest
tag_with_ref: true
deploy_to_kubernetes_cluster:
... what to do here?
I am able to built the image and push to gihub packages.
I have created deployment.yml in the root directory of the repository.
How can I deploy to kubernetes cluster?
Also, I am tagging the images with latest. Is it fine or I need to use GITHUB_REF for tagging?
Update
I am able to configure all the things. I only need to get kubeconfig to authenticate to existing cluster.

sed -i'' -e 's/IMAGE_LABEL/${{ github.sha }}/g' deployment.yml
kubectl apply -f deployment.yml
By looking your workflow config file, all the jobs running parallelly.
But, probably it's not what you want.
Pushing image needs a built image and deployment job needs an updated built image.
On Access kubernetes cluster, just access into your cluster and do,
cat $HOME/.kube/config
and copy the output.
Now, create a secret in github with KUBE_CONFIG as environment variable.
Notes - this is one method to access kubernetes cluster, there are other methods as well, choose one that suits your need
