velero-examples's Introduction

velero-examples

This repo provides a few examples using velero to back up and restore applications. The CLI invocations use kubectl where it would work, and oc when there are openshift-specific resources involved. In a base kubernetes environment, some modification might be needed (use Deployments instead of DeploymentConfigs, etc.)

Install Velero (1.2 release)

The velero image used is the upstream 1.2 release from docker.io. The only plugin included is the aws plugin required for supporting an aws/s3 BackupStorageLocation

TODO: modify scripts to take VELERO_* from env/input to avoid risk of committing credentials to github.

  • replace VELERO_ACCESS_KEY_ID and VELERO_SECRET_ACCESS_KEY in velero-install/aws-credentials with your values (make sure this change doesn't get committed to github)
  • replace VELERO_BUCKET_NAME in velero-install/velero-server.yaml with your bucket name
kubectl apply -f velero-install/crds.yaml
kubectl apply -f velero-install/velero-namespace.yaml
kubectl create secret generic cloud-credentials --namespace velero --from-file cloud=velero-install/aws-credentials
kubectl apply -f velero-install/velero-server.yaml

velero-examples's Issues

Getting ImagePullBack while deploying pgbench.yaml to cluster

Hi,

I was trying using patroni example to test velero backup and restore in OpenShift cluster. I deployed all the resources mentioned in repository but pgbench.yaml not deploying successfully as it's looking for quay.io/sagyvolkov/pgbench-container:0.1 container image which seems to not having access. I tried searching for that image from my quay.io account and even on internet but not getting. Can we make it public or mention the steps to create pgbench-container image locally.

Issue with hooks for cassandra

Tried B/R with noobaa enabled for cassandra and the backup partially failed with the following logs

Example with DeploymentConfig controller fail to restore

The mysql-persistent example fails to restore as is. If I modify the installation template to use a Deployment instead, everything works well.
Possibly related to: vmware-tanzu/velero#1981

I'm using the following Docker image/tags in my project:
https://github.com/rflorenc/openshift-backup-infra/blob/master/hack/docker_images.list

Components installed in order:
Noobaa S3
Velero (using Noobaa s3 as default BSL)
Restic Restore Helper Configmap
Openshift-Velero-Plugin

If I use a DC, Restic's pvc/pv restore times out. A working project is restored, but the mounted pod name and data will not match the one in the initial Backup.
