Running HA MariaDB on Azure Kubernetes Service (AKS)
Running HA MariaDB with Rancher Kubernetes Engine (RKE)

And now, onto the post…

Red Hat OpenShift is a comprehensive enterprise-grade application platform built for containers powered by Kubernetes. OpenShift lets developers quickly build, develop, and deploy applications on nearly any infrastructure, public or private. It offers enterprises full control over their Kubernetes environments, whether they’re on-premise or in the public cloud, giving teams freedom to build and run applications anywhere.

Portworx recently achieved Red Hat certification for Red Hat OpenShift Container Platform and PX-Enterprise is available in the Red Hat Container Catalog. This certification enables enterprises to confidently run high-performance stateful applications like databases, big and fast data workloads, and machine learning applications on the Red Hat OpenShift Container Platform. Learn more about Portworx & OpenShift in our Product Brief.

This tutorial is a walk-through of the steps involved in deploying, managing, and backing up a highly available MariaDB database on OpenShift.

In summary, to backup and recover an HA MariaDB database on OpenShift you need to:

  1. Create an OpenShift cluster running at least three nodes
  2. Install a cloud native storage solution like Portworx as a DaemonSet on OpenShift
  3. Create a storage class defining your storage requirements like replication factor, snapshot policy, and performance profile
  4. Deploy MariaDB using Kubernetes
  5. Take a snapshot of Kubernetes PV
  6. Restore MariaDB using the Kubernetes persistent volume snapshot

How to install and configure an OpenShift Origin cluster

OpenShift Origin can be deployed in a variety of environments ranging from VirtualBox to a public cloud IaaS such as Amazon, Google, Azure. Refer to the official installation guide for the steps involved in setting up your own cluster. For this guide, we run an OpenShift Origin cluster in Microsoft Azure. Follow the instructions mentioned in Azure documentation.

Your OpenShift cluster setup should look similar to the below configuration. It is recommended that you run at least 3 nodes for the HA configuration.

$ oc get nodes

Though almost all the steps can be performed through the OpenShift Console, we are using the oc CLI. Please note that most of the kubectl commands are available through oc tool. You may find the tools used interchangeably.

Installing Portworx on OpenShift

Since OpenShift is based on Kubernetes, the steps involved in installing Portworx are not very different from the standard Kubernetes installation. Portworx documentation has a detailed guide with the prerequisites and all the steps to install on OpenShift.

Before proceeding further, ensure that Portworx is up and running on OpenShift.

$ oc get pods -n=kube-system -l name=portworx

px-mariadb-okd-1

We can check the status of Portworx by running the following commands:

$ PX_POD=$(oc get pods -l name=portworx -n kube-system -o jsonpath='{.items[0].metadata.name}')

$ oc exec -it $PX_POD -n kube-system -- /opt/pwx/bin/pxctl status

Once OpenShift Origin cluster is up and running and Portworx is installed and configured, we will deploy a highly available MariaDB database.

Creating a Kubernetes storage class for MariaDB

Through storage class objects, an admin can define different classes of Portworx volumes that are offered in a cluster. These classes will be used during the dynamic provisioning of volumes. The storage class defines the replication factor, IO profile (e.g. for a database or a CMS), and priority (e.g. SSD or HDD). These parameters impact the availability and throughput of workload and can be specified for each volume. This is important because a production database will have different requirements than a development Jenkins cluster.

In this example, the storage class that we deploy has a replication factor of 3 with I/O profile set to “db,” and priority set to “high.” This means that the storage will be optimized for low latency database workloads like MariaDB and automatically placed on the highest performance storage available in the cluster. Notice that we also mention the filesystem, xfs in the storage class.

$ cat > px-mariadb-sc.yaml << EOF
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
    name: px-ha-sc
provisioner: kubernetes.io/portworx-volume
parameters:
   repl: "3"
   io_profile: "db_remote"
   priority_io: "high"
   fs: "xfs"
EOF
$ oc create -f px-mariadb-sc.yaml
storageclass.storage.k8s.io "px-ha-sc" created

$ oc get sc
NAME                PROVISIONER                     AGE
px-ha-sc            kubernetes.io/portworx-volume   10s
stork-snapshot-sc   stork-snapshot                  3d

Create the storage class and verify its available in the default namespace.

$ oc create -f px-mariadb-sc.yaml
storageclass.storage.k8s.io "px-ha-sc" created

$ oc get sc
NAME                PROVISIONER                     AGE

stork-snapshot-sc   stork-snapshot                  17m

Creating a MariaDB PVC on OpenShift

We can now create a Persistent Volume Claim (PVC) based on the Storage Class. Thanks to dynamic provisioning, the claims will be created without explicitly provisioning a persistent volume (PV).

$ cat > px-mariadb-pvc.yaml << EOF
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
   name: px-mariadb-pvc
   annotations:
     volume.beta.kubernetes.io/storage-class: px-ha-sc

   resources:
     requests:
       storage: 1Gi
EOF

$ 	
persistentvolumeclaim "px-mariadb-pvc" created

$ oc  get pvc
NAME           STATUS    VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
px-mariadb-pvc   Bound     pvc-739a7151-9a8d-11e8-9135-000d3a1a1cdf   1Gi        RWO            px-ha-sc       13s

Deploying MariaDB on OpenShift

Finally, let’s create a MariaDB instance as a Kubernetes deployment object. For simplicity’s sake, we will just be deploying a single mariadb pod. Because Portworx provides synchronous replication for High Availability, a single MariaDB instance might be the best deployment option for your MariaDB database. Portworx can also provide backing volumes for multi-node MariaDB cluster. The choice is yours.

$ cat > px-mariadb-app.yaml << EOF
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mariadb
spec:
  selector:
    matchLabels:
      app: mariadb
  strategy:
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
    type: RollingUpdate
  replicas: 1
  template:
    metadata:
      labels:
        app: mariadb
    spec:
      schedulerName: stork
      containers:
      - name: mariadb
        image: mariadb:latest
        imagePullPolicy: "Always"
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: password        
        ports:
        - containerPort: 3306
        volumeMounts:
        - mountPath: /var/lib/mysql
          name: mariadb-data
      volumes:
      - name: mariadb-data
        persistentVolumeClaim:
          claimName: px-mariadb-pvc
EOF

$ oc create -f px-mariadb-app.yaml
deployment "mariadb" created

The MariaDB deployment defined above is explicitly associated with the PVC, px-mariadb-pvc created in the previous step.

This deployment creates a single pod running MariaDB backed by Portworx.

$ oc get pods
NAME                       READY     STATUS    RESTARTS   AGE
docker-registry-2-7dwtc    1/1       Running   1          1d

router-1-lqsxs             1/1       Running   1          1d

We can inspect the Portworx volume by accessing the pxctl tool running with the MariaDB pod.

$ VOL=`oc get pvc | grep px-mariadb-pvc | awk '{print $3}'`
$ PX_POD=$(oc get pods -l name=portworx -n kube-system -o jsonpath='{.items[0].metadata.name}')
$ oc exec -it $PX_POD -n kube-system -- /opt/pwx/bin/pxctl volume inspect ${VOL}

Failing over MariaDB pod on OpenShift

Populating sample data

Let’s populate the database with some sample data.

We will first find the pod that’s running MariaDB to access the shell.

$ POD=`oc get pods -l app=mariadb | grep Running | grep 1/1 | awk '{print $1}'`

$ oc exec -it $POD -- mariadb -uroot -ppassword

Let’s run a few queries on the table.

+------------+---------------+-----------------+
3 rows in set (0.00 sec)

Exit from the MariaDB shell to return to the host.

Simulating node failure

Now, let’s simulate node failure by cordoning off the OpenShift node on which MariaDB is running.

$ NODE=`oc get pods -l app=mariadb -o wide | grep -v NAME | awk '{print $7}'`

$ oc adm cordon ${NODE}
node "mycluster-node-1" cordoned

The above command disabled scheduling on one of the nodes.

$ oc get nodes

mycluster-node-2     Ready                      compute   1h        v1.9.1+a0ce1bc657

Now, let’s go ahead and delete the mariadbDB pod.

$ POD=`oc get pods -l app=mariadb -o wide | grep -v NAME | awk '{print $1}'`
$ oc delete pod ${POD}
pod "mariadb-654cc68f68-gxxbd" deleted

As soon as the pod is deleted, it is relocated to the node with the replicated data. Storage Orchestrator for Kubernetes (STORK), a Portworx-contributed open source storage scheduler, ensures that the pod is co-located on the exact node where the data is stored. It ensures that an appropriate node is selected for scheduling the pod.

Let’s verify this by running the below command. We will notice that a new pod has been created and scheduled in a different node.

$ oc get pods -l app=mariadb -o wide
NAME                     READY     STATUS    RESTARTS   AGE       IP               NODE

Let’s uncordon the node to bring it back to action.

$ oc adm uncordon ${NODE}
node "mycluster-node-1" uncordoned

Finally, let’s verify that the data is still available.

Verifying that the data is intact

Let’s find the pod name and run the ‘exec’ command, and then access the MariaDB shell.

$ oc exec -it $POD -- mysql -uroot -ppassword

Observe that the database table is still there and all the content is intact! Exit from the client shell to return to the host.

Taking Snapshots of a Kubernetes volume and restoring the database

Portworx supports creating snapshots for OpenShift PVCs.

Let’s create a snapshot for the PVC we created for MariaDB.

cat >  px-mariadb-snap.yaml << EOF
apiVersion: volumesnapshot.external-storage.k8s.io/v1
kind: VolumeSnapshot
metadata:

EOF

$ oc create -f px-mariadb-snap.yaml
volumesnapshot.volumesnapshot.external-storage.k8s.io "px-mariadb-snapshot" created

Verify the creation of volume snapshot.

$ oc get volumesnapshot

Since snapshots are just like volumes, we can use it to start a new instance of MariaDB. Let’s create a new instance of MariaDB by restoring the snapshot data.

$ cat > px-mariadb-snap-pvc << EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: px-mariadb-snap-clone
  annotations:
    snapshot.alpha.kubernetes.io/snapshot: px-mariadb-snapshot
spec:
  accessModes:
     - ReadWriteOnce
  storageClassName: stork-snapshot-sc
  resources:
    requests:
      storage: 2Gi
EOF

$ oc create -f px-mariadb-snap-pvc.yaml
persistentvolumeclaim "px-mariadb-snap-clone" created

From the new PVC, we will create a MariaDB pod.

$ cat < px-mariadb-snap-restore.yaml >> EOF
apiVersion: apps/v1
kind: Deployment

  name: mariadb-snap
spec:
  selector:
    matchLabels:

                values:

              - key: px/enabled
                operator: NotIn

        env:
        - name: MYSQL_ROOT_PASSWORD
          value: password       
        ports:
        - containerPort: 3306
        volumeMounts:
        - mountPath: /var/lib/mysql
          name: mariadb-data
      volumes:
      - name: mariadb-data
        persistentVolumeClaim:
          claimName: px-mariadb-snap-clone
EOF

$ oc create -f px-mariadb-snap-restore.yaml
deployment "mariadb-snap" created

Verify that the new pod is in running state.

$ oc get pods -l app=mariadb-snap
NAME                         READY     STATUS    RESTARTS   AGE
mariadb-snap-5ddd6b6848-bb6wx   1/1       Running   0          30s

Finally, let’s access the sample data created earlier in the walkthrough.

$ POD=`oc get pods -l app=mariadb-snap | grep Running | grep 1/1 | awk '{print $1}'`
$ oc exec -it $POD -- mysql -uroot -ppassword

Notice that the collection is still there with the data intact.

We can also push the snapshot to Amazon S3 if we want to create a Disaster Recovery backup in another region. Portworx snapshots also work with any S3 compatible object storage, so the backup can go to a different cloud or even an on-premises data center. Alternatively, we can stretch a single Portworx cluster across two independent Kubernetes clusters for Zero RPO DR for Kubernetes.

Summary

Portworx can be easily deployed on Red Hat OpenShift to run stateful workloads in production, including mission-critical data management functions like backup and restore. Through the integration of Portworx and OpenShift, DevOps and DataOps teams can seamlessly run highly available database clusters in OpenShift. They can perform traditional operations such as volume expansion, snapshots, backup and recovery for the cloud-native applications.
