Centralized helm chart microservice template deployed to GCS w/ gitlab-ci
When deploying a lot of similar workload to kubernetes, it is convenient to use helm for templating and release management.
This repo implements a kubernetes-builder image with its dependencies (google-cloud-sdk with kubectl, helm, ...) and automatically packages a helm chart and uploads it to Google Cloud Storage bucket.
Each microservice has its own gitlab repo and values.yaml. In its own .gitlab-ci.yml you can do something like this:
deploy-devel:
stage: deploy-dev
...
script:
- cd build
- helm init --upgrade
- helm repo add my-helm-chart https://my-helm-charts.storage.googleapis.com/
- helm repo list | grep my-helm-chart
- |
helm upgrade --install --namespace=$NAMESPACE --debug "$APP_NAME"-devel -f helm/values.yaml \
--set image.repository=$IMAGE_REPO \
--set image.tag=$IMAGE_TAG \
--set namespace=$NAMESPACE \
--set env.sqlUser=$SQL_USER \
--set env.sqlPassword=$SQL_PASSWORD \
--set env.sqlName=$SQL_NAME \
--set env.host=$URL_HOST \
my-helm-chart/my-service
... and other stages with their namespaces and so on...
check .gitlab-ci.yml to see how the helm chart is packaged and deployed to GCS
don't forget to set the proper GITLAB_VARIABLES
