[ Kube 45 ] Velero - Backup & Restore Kubernetes Cluster

In this Video, I will show you how to backup and/or restore your Kubernetes cluster using an open source project Velero.
Velero (formerly Heptio Ark) gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. Velero lets you:
- Take backups of your cluster and restore in case of loss.
- Copy cluster resources to other clusters.
- Replicate your production environment for development and testing environments.
Velero consists of:
- A server that runs on your cluster
- A command-line client that runs locally

Cluster Migration using velero:- - need 2 cluster - create namespace in cluster 1 - install velero server on cluster1 and take backup of namespace from cluster1 - now install velero server with same minio credentials and endpoint on cluster 2 - check velero backup available on cluster2 which we created on cluster1 - now restore backup on cluster2 - on cluster2 namaspace is available Migration completed

Hi Narasimha, thanks for watching this video. I haven't tried it on AWS yet. Just on my local environment. In order to backup and restore persistent volumes, you will have to use supported storage provider in the first place.

In which node velero needs to be installed? Is it master or any worker node? Is it possible to install it outside the K8s cluster and has access to the K8s cluster?

[@justmeandopensource]

Hi Anusha, Thanks for watching. Velero installation actually deploys certain resources in your Kubernetes cluster. It doesn't deploy them specifically on master or worker nodes but just to your cluster. The resources/pods can actually run on any nodes. Velero installation consists of downloading the velero binary and installing the required components into the cluster.

Very Helpful video .....My scenario is we want to shutdown/delete eks cluster for a few months and then restore back (until then we won't have any eks cluster to store backup endpoints or objects) so will this help me if not please can you suggest alternative

[@justmeandopensource]

Hi Ashish, thanks for watching. I don't think you can shutdown an EKS managed cluster. You can however reduce the number of worker nodes. But if you are not going to use, then the only possibility is to delete the EKS cluster. Velero is exactly for this. Just take a backup of your cluster including persistent volumes and then you can restore it to any cluster.

Thanks a lot. This is something that I've been waiting for! I've few doubts though. In my case, I've to host multiple WordPress sites. Each site will have its own namespace 1) Is Velero production-ready to back PV? All my states are saved in NFS servers mounted as PV 2) How can I backup/restore programmatically, like by calling an API? My use case is that my clients should be able to backup/restore their wp site on clicking a button

[@justmeandopensource]

Hi Gijo, thanks for watching this video. Velero is production ready and it can backup persistent volumes as well. Having said that, it doesn't support all persistent volumes. You will have to use a supported storage provisioner to make use of volume snapshots. Unfortunately its not a lot that is supported at the moment. heptio.github.io/velero/master/support-matrix.html NFS is not supported. I am not sure of any API for programmatic access. Thanks

Hi Prashanth, thanks for watching this video. You can absolutely use Velero to move your cluster from one region to another. You can backup everything and restore just what you want on the target cluster. If you are using cloud provider, then you can also backup the PV. Unfortunatley I am not there yet. All my clusters are based on bare metal on-prem and my storage solution for PVs are NFS, which are not supported by Velero. Thanks.

[@justmeandopensource]

@Rohan Shinde Clearly NFS storage provisioning is not supported by Velero. It has to be one of their supported storage provider, if you want to do backups of persistent volumes. It is very unfortunate they don't support NFS. Having said that, there is Restic integration with Velero, which you can use for NFS snapshots.

Excelent video !!! Can you do a ETCD backup with Velero and restore the cluster ? ( im investigation to do that in a HA cluster of k8s)

[@justmeandopensource]

Hi Gonzalo, thanks for watching this video. Basically, you don't have to backup etcd separately. When you are performing a backup using Velero, it queries the etcd for the current state of the cluster. Etcd is the datastore and is used during the backup. If you want to backup etcd, then you can create a snapshot of the current state of the etcd datastore. I came across below article in Coreos website. support.coreos.com/hc/en-us/articles/115000323894-Creating-etcd-backup Thanks.

Can I migrate the whole cluster to different CIDR of node ip? Different VPC

Hi Antony, thanks for watching. So you have deployed velero in your existing Kubernetes cluster and took the backup of what you want. Now in order to restore it to a different kubernetes cluster, you will have to update your kubeconfig file to point to the new k8s cluster. Velero uses your kubeconfig file to interact with the k8s cluster. You are still connecting to the same minio object storage server where the backups are. Then you can follow the same process shown in this video to restore from backup. Cheers.

velero install command failed, An error occurred: --plugins flag is required

[@justmeandopensource]

Hi, thanks for watching this video. I used v1.0.0 of Velero (github.com/vmware-tanzu/velero/releases/tag/v1.0.0). The latest version is v1.2.0 (github.com/vmware-tanzu/velero/releases/tag/v1.2.0) which introduced this requirement of --plugin to the velero install command. But reading through the documentation, it was mentioned that --plugin is optional.

@@justmeandopensource Here is one answer that will work: velero install --provider aws --plugins velero/velero-plugin-for-aws:v1.0.0 --kubeconfig config --bucket bucketone --secret-file ./minio.credentials --backup-location-config region=minio,s3ForcePathStyle=true,s3Url=10.12.16.144:9000 where velero version is v1.2.0 velero plugin for AWS svelero/velero-plugin-for-aws:v1.0.0 config is config for your kubernetes cluster 10.12.16.144:9000 is the address for Minio container bucketone is Minio storage bucket

Velero pod is failing with below error "An error occurred: some backup storage locations are invalid: backup store for location "default" is invalid: rpc error: code = Unknown desc = RequestError: send request failed caused by: Get 127.0.0.1:9000/kubedemo?delimiter=%2F&list-type=2&prefix=: dial tcp 127.0.0.1:9000: connect: connection refused"

[@jla.]

Do the following: kubectl delete deploy velero -n velero && kubectl delete ns velero Then when you rerun the velero install command make sure you put your computers local address such as (192.168.1.2) in the s3Url=:9000 part of the command. Additional note for anyone who has a more up to date version of the velero binary you will need to include an additional --plugins flag Here was my command: velero install \ --provider aws \ --plugins velero/velero-plugin-for-aws:v1.1.0 \ --bucket kubebackup \ --secret-file ./minio.credentials \ --backup-location-config region=minio,s3ForcePathStyle=true,s3Url=192.168.1.2:9000 I was unable to get this demo to work as even with my local IP in the install command i would get a failed connection from the kind cluster to the docker minio. I took the path of installing minio into my cluster using helm (helm install stable/minio -n minio) and for s3Url=minio.default.svc.cluster.local:9000 and that worked.

Can you restore a backup on another cluster?

[@justmeandopensource]

Hi, thanks for watching. Yes you can restore it into another cluster.

No worries.

[@justmeandopensource]

Hi Anbu, thanks for watching. Is it just this namespace that you have problems backing up? Have you tried any other namespace or any other backup options? None of you backups are completing?

[@justmeandopensource]

It will be hard to troubleshoot remotely. I haven't had any of those problems. Its worth getting as much information as possible and ask in StackOverflow with much details. Sorry I couldn't be of any help here.

Deleting Backups Use the following commands to delete Velero backups and data: kubectl delete backup -n will delete the backup custom resource only and will not delete any associated data from object/block storage velero backup delete will delete the backup resource including all data in object/block storage

Hi venkat. Excellent content and presentation. Can you please do a demo for back up and restore of pv? Preferably mongodb replicas. Is that possible in Valero?

[@justmeandopensource]

Hi Sanjeev, thanks for watching this video. Backup and restoring of persistent volumes is possible with Velero. But you need to use a supported storage provider for that. Unfortunately in my setup on bare metal, I use nfs-provisioner which is not supported by Velero. If you happen to use any of the managed Kubernetes in the cloud (EKS, GKE, Azure), its possible to test pv backup restore. In the future, I will see if I can get that done in AWS. Thanks.
