IMAGE_TAG: nickname-organization/your-image-name-here:$CI_COMMIT_SHA
stages:
- test
- build
- deploy
Verify lint and run tests:
image: node:16.13.0

services:
- redis:latest
- postgres:latest
variables:

Build and push image to Dockerhub:
image: docker:latest
stage: build
script:
- echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_USERNAME" --password-stdin
- docker pull $IMAGE_LATEST || true
- docker build --cache-from $IMAGE_LATEST -t $IMAGE_TAG -t $IMAGE_LATEST .
- docker push $IMAGE_TAG
- docker push $IMAGE_LATEST
only:
- main
Deploy image to K8S Cluster:
image: jlenon7/gitlab-deploy:latest
stage: deploy
script:
- aws configure set aws_access_key_id $AWS_ACCESS_KEY_ID
- aws configure set aws_secret_access_key $AWS_SECRET_ACCESS_KEY
- aws configure set region $AWS_DEFAULT_REGION
- aws eks --region $AWS_DEFAULT_REGION update-kubeconfig --name eks-$AWS_DEFAULT_REGION-production
- templating generate ./manifest/templates --set IMAGE_TAG=$IMAGE_TAG
- kubectl apply -f ./manifest/config-map.yml -f ./manifest/deployment.yml
