Deploy to kubernetes cluster with github workflow - docker

Question

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.

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
