## Deploy on Kubernetes

To deploy MySQL 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 to S3 storage

```yaml
apiVersion: batch/v1
kind: Job
metadata:
  name: backup
spec:
  template:
    spec:
      containers:
        - name: mysql-bkup
          # In production, it is advised to lock your image tag to a proper
          # release version instead of using `latest`.
          # Check https://github.com/jkaninda/mysql-bkup/releases
          # for a list of available releases.
          image: jkaninda/mysql-bkup
          command:
            - /bin/sh
            - -c
            - backup --storage s3
          resources:
            limits:
              memory: "128Mi"
              cpu: "500m"
          env:
            - name: DB_PORT
              value: "3306"
            - name: DB_HOST
              value: ""
            - name: DB_NAME
              value: "dbname"
            - name: DB_USERNAME
              value: "username"
            # Please use secret!
            - name: DB_PASSWORD
              value: ""
            - name: AWS_S3_ENDPOINT
              value: "https://s3.amazonaws.com"
            - name: AWS_S3_BUCKET_NAME
              value: "xxx"
            - name: AWS_REGION
              value: "us-west-2"
            - name: AWS_ACCESS_KEY
              value: "xxxx"
            - name: AWS_SECRET_KEY
              value: "xxxx"
            - name: AWS_DISABLE_SSL
              value: "false"
      restartPolicy: Never
```

## Backup Job to SSH remote server

```yaml
apiVersion: batch/v1
kind: Job
metadata:
  name: backup
spec:
  ttlSecondsAfterFinished: 100
  template:
    spec:
      containers:
      - name: mysql-bkup
        # In production, it is advised to lock your image tag to a proper
        # release version instead of using `latest`.
        # Check https://github.com/jkaninda/mysql-bkup/releases
        # for a list of available releases.
        image: jkaninda/mysql-bkup
        command:
        - /bin/sh
        - -c
        - bkup
        - backup
        - --storage
        - ssh
        - --disable-compression
        resources:
          limits:
            memory: "128Mi"
            cpu: "500m"
        env:

            value: "3306"
          - name: DB_HOST
            value: ""
          - name: DB_NAME
            value: "dbname"
          - name: DB_USERNAME

## Recurring backup

```yaml
apiVersion: batch/v1
kind: CronJob
metadata:
  name: backup-job
spec:
  schedule: "* * * * *"
  jobTemplate:
    spec:
      template:

## Kubernetes Rootless

This image also supports Kubernetes security context, you can run it in Rootless environment.
It has been tested on Openshift, it works well.
Deployment on OpenShift is supported, you need to remove `securityContext` section on your yaml file.

```yaml
apiVersion: batch/v1
kind: CronJob
metadata:
  name: backup-job
spec:
  schedule: "* * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          securityContext:
            runAsUser: 1000
            runAsGroup: 3000
            fsGroup: 2000
          containers:
            # In production, it is advised to lock your image tag to a proper
            # release version instead of using `latest`.
            # Check https://github.com/jkaninda/mysql-bkup/releases
            # for a list of available releases.
