Deploy on Kubernetes

To deploy PostgreSQL Backup on Kubernetes, you can use Job to backup or Restore your database. For recurring backup you can use CronJob, you don't need to run it in scheduled mode. as described bellow.

Backup Job

apiVersion: batch/v1
kind: Job
metadata:
  name: backup
spec:
  ttlSecondsAfterFinished: 100
  template:
    spec:
      containers:
      - name: pg-bkup
        image: jkaninda/pg-bkup
        command:
        - bkup
        - backup
        - --storage
        - ssh
        - --disable-compression
        resources:
          limits:
            memory: "128Mi"
            cpu: "500m"
        env:
          - name: DB_PORT
            value: "5432"
          - name: DB_HOST
            value: ""
          - name: DB_NAME
            value: "dbname"
          - name: DB_USERNAME
            value: "postgres"
          # Please use secret!
          - name: DB_PASSWORD
            value: ""
          - name: SSH_HOST_NAME
            value: "xxx"

            value: "xxxx"
          - name: SSH_REMOTE_PATH
            value: "/home/toto/backup"
          # Optional, required if you want to encrypt your backup
          - name: GPG_PASSPHRASE
            value: "xxxx"
      restartPolicy: Never
