Bug Fix and Enhancements

We have also squashed a few bugs and added a few enhancements in this release. Here are some of the highlighting fixes & enhancements.

• Support passing args to restic backup/restore command: We have added the support for passing arguments to restic backup and restore command. Now User can pass optional arguments to the restic backup/restore process via spec.target.args field of BackupConfiguration/RestoreSession. Here are some examples:

  Pass args to restic backup command:

  apiVersion: stash.appscode.com/v1beta1
  kind: BackupConfiguration
  metadata:
    name: sample-deployment-backup
    namespace: demo
  spec:
    repository:
      name: deployment-backup-repo
    schedule: "*/5 * * * *"
    target:
      ref:
        apiVersion: apps/v1
        kind: Deployment
        name: sample-deployment
      volumeMounts:
        - name: source-data
          mountPath: /source/data
      paths:
        - /source/data
      args: ["--ignore-inode", "--tag=t1,t2"]
    retentionPolicy:
      name: "keep-last-5"
      keepLast: 5
      prune: true
  

  Pass args to restic restore command:

  apiVersion: stash.appscode.com/v1beta1
  kind: RestoreSession
  metadata:
    name: sample-deployment-restore
    namespace: demo
  spec:
    repository:
      name: deployment-backup-repo
    target:
      ref:
        apiVersion: apps/v1
        kind: Deployment
        name: sample-deployment
      volumeMounts:
        - name: source-data
          mountPath: /source/data
      rules:
        - paths:
            - /source/data/
      args: ["--tag=t1,t2"]
  

• Fix license-reader ClusterRoleBinding cleaning: Some of our users were facing issues with license-reader ClusterRoleBinding not getting deleted after deleting the respective RestoreSession. We have fixed the issue in this release. Now, the ClusterRoleBinding should get deleted when a user deletes the respective RestoreSession.

• Use restic v0.12.1: In this release, we have upgraded the restic version to v0.12.1.

• Show actual repository size instead of logical size: Previously, Stash showed the logical size of the repository which did not reflect the actual repository size. We have fixed this issue. Now, your Repository size should be the same as how much actual data is in the backend.

• Update restic docker image in Stash kubectl plugin: We have upgraded the underlying restic docker image used by Stash kubectl plugin.

• TLS support in Redis add-on: We have added the TLS support for redis add-on in this release.

• MongoDB 5.0.3 and PostgreSQL 14.0 support: We have added support for MongoDB 5.0.3. Now, you can backup your MongoDB 5.x.x using this add-on. We have also added support for PostgreSQL 14.0.
