Quickstart for NFS backup

Install NFS server

1. Prepare Storage

Create the NFS PV and SC.

kubectl apply -f config/samples/nfs_pv.yaml 

You can specify the PVC you created by modifying the persistentVolumeClaim.claimName in the config/samples/nfs_server.yaml.

2. Create nfs server

Create ReplicationController and Service.

kubectl apply -f config/samples/nfs_server.yaml 

Get NFSServerAddress.

# example
kubectl get svc nfs-server --template={{.spec.clusterIP}}
10.96.253.82

Create a NFS backup

1. Configure address of NFS Server.

# config/samples/mysql_v1alpha1_backup.yaml
NFSServerAddress: "10.96.253.82"

2. Create a backup

kubectl apply -f config/samples/mysql_v1alpha1_backup.yaml

Notice: backup cr and mysqlcluster cr must be in the same namespace.

3. Verify your backup

You can find the backup folder called <cluster name>_<timestamp>.

kubectl exec -it <pod name of nfs server> -- ls /exports
index.html  initbackup  sample_2022419101946

Restore cluster from exist NFS backup

Configure the mysql_v1alpha1_cluster.yaml, uncomment the nfsServerAddress field and fill in your own configuration.

...
restoreFrom: "sample_2022419101946"
nfsServerAddress: 10.96.253.82

Notice: restoreFrom is the folder name of a backup. You can find it on the path mounted in NFS Server.

Create cluster from NFS server backup copy:

kubectl apply -f config/samples/mysql_v1alpha1_cluster.yaml

Build your own image

docker build -f Dockerfile.sidecar -t  acekingke/sidecar:0.1 . && docker push acekingke/sidecar:0.1
docker build -t acekingke/controller:0.1 . && docker push acekingke/controller:0.1

You can replace acekingke/sidecar:0.1 with your own tag

Deploy your own manager

make manifests
make install 
make deploy  IMG=acekingke/controller:0.1 KUSTOMIZE=~/radondb-mysql-kubernetes/bin/kustomize
