keptn-gitea-provisioner-service

This repository contains a reference implementation for a Keptn extension which auto-provisions git upstream repositories in Gitea.

Compatibility Matrix

Keptn Version*	Keptn-Service-Template-Go Docker Image
0.15, 0.16	keptn-sandbox/keptn-gitea-provisioner-service:0.1.0
0.17.0	keptn-sandbox/keptn-gitea-provisioner-service:0.1.1

* This is the Keptn version we aim to be compatible with. Other versions should work too, but there is no guarantee.

Quickstart

• The keptn-gitea-provisioner-service can be easily installed with helm and is able to create the credentials for the Gitea instance:

  #!/bin/bash
  VERSION=0.1.0
  NAMESPACE=default
  GITEA_ENDPOINT="http://gitea-http.${NAMESPACE}:3000/"
   GITEA_ADMIN_USERNAME=#Define a username for the admin
   GITEA_ADMIN_PASSWORD=#Define a password for the admin
  
  helm install keptn-gitea-provisioner-service https://github.com/keptn-sandbox/keptn-gitea-provisioner-service/releases/download/${VERSION}/keptn-gitea-provisioner-service-${VERSION}.tgz \
        --set gitea.admin.create=true \
        --set gitea.admin.username=${GITEA_ADMIN_USERNAME} \
        --set gitea.admin.password=${GITEA_ADMIN_PASSWORD} \
        --set gitea.endpoint=${GITEA_ENDPOINT} \
        --wait

  Note: You can re-use existing credentials by omitting the set parameters of the helm installation; For a full list of options that can be set see the chart helm documentation.

• In case you need a simple Gitea instance, you can create it with following bash script:

  #!/bin/bash
  NAMESPACE=default #Should be configured to match the GITEA_ENDPOINT environment variable when installing the provisioner
  
  # Add the gitea helm charts and install gitea to the cluster
  helm repo add gitea-charts https://dl.gitea.io/charts/
  helm repo update
  
  # Install gitea in the 
  helm install gitea gitea-charts/gitea \
      --set memcached.enabled=false \
      --set postgresql.enabled=false \
      --set gitea.config.database.DB_TYPE=sqlite3 \
      --set gitea.admin.existingSecret=gitea-admin-secret \
      --set gitea.config.server.OFFLINE_MODE=true \
      --set gitea.config.server.ROOT_URL=http://gitea-http.${NAMESPACE}:3000/

• Keptn must be configured to use the keptn-gitea-provisioner-service to automatically provision git repositories. The flag is different for Keptn version 0.16 and version 0.17 and onwards:

  #!/bin/bash
  NAMESPACE=default
  
  # Keptn 0.17
  helm upgrade -n keptn keptn keptn/keptn \
    --set "features.automaticProvisioning.serviceURL=http://keptn-gitea-provisioner-service.${NAMESPACE}"
  
  # Keptn 0.16
  helm upgrade -n keptn keptn keptn/keptn \
    --set "control-plane.features.automaticProvisioningURL=http://keptn-gitea-provisioner-service.${NAMESPACE}"

Deploy in your Kubernetes cluster

To deploy the current version of the keptn-gitea-provisioner-service in your Keptn Kubernetes cluster use the helm chart file, for example:

helm install -n keptn keptn-gitea-provisioner-service chart/

This should install the keptn-gitea-provisioner-service together with a Keptn distributor into the keptn namespace, which you can verify using

kubectl -n keptn get deployment keptn-gitea-provisioner-service -o wide
kubectl -n keptn get pods -l run=keptn-gitea-provisioner-service

Up- or Downgrading

Adapt and use the following command in case you want to up- or downgrade your installed version (specified by the $VERSION placeholder):

helm upgrade -n keptn --set image.tag=$VERSION keptn-gitea-provisioner-service chart/

Uninstall

To delete a deployed keptn-gitea-provisioner-service, use the file deploy/*.yaml files from this repository and delete the Kubernetes resources:

helm uninstall -n keptn keptn-gitea-provisioner-service
