Run GitBucket + PostgreSQL on Kubernetes

gitbucket-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: gitbucket
  labels:
    app: gitbucket
spec:
  containers:
  - name: postgresql
    image: postgres:9.5-alpine
    volumeMounts:
    - name: gitbucket-postgresql-data
      mountPath: /var/lib/postgresql/data
    env:
    - name: POSTGRES_DB
      value: gitbucket
    - name: POSTGRES_USER
      value: gitbucket
    - name: POSTGRES_PASSWORD
      value: gitbucket
    ports:
    - containerPort: 5432
  - name: gitbucket
    image: takezoe/gitbucket
    volumeMounts:
    - name: gitbucket-data
      mountPath: /gitbucket
    env:
    - name: GITBUCKET_DB_URL
      value: jdbc:postgresql://localhost/gitbucket
    - name: GITBUCKET_DB_USER
      value: gitbucket
    - name: GITBUCKET_DB_PASSWORD
      value: gitbucket
    ports:
    - containerPort: 8080
  volumes:
  - name: gitbucket-data
    emptyDir: {}
  - name: gitbucket-postgresql-data
    emptyDir: {}

$ kubectl apply -f gitbucket-pod.yaml
$ kubectl expose pod gitbucket --type=NodePort --port=8080
$ kubectl get service gitbucket
NAME        TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
gitbucket   NodePort   10.105.159.36   <none>        8080:30010/TCP   2m

In this case, GitBucket is running at port 30010 on the deployed node. If you are doing this tutorial with minikube on MacOS, you can open GitBucket in your browser by following command:

$ open "http://$(minikube ip):30010"
