In the example I am looking at they use NFS PV and it is quite simple as I can access the NFS file system associated with a PV and I can add files to it. machine and the remote container. reclaimed according to a Retain reclaim policy, its claimRef $ kubectl apply --filename spc-vault-database.yaml Copy The vault-database SecretProviderClass describes one secret object: objectName is a symbolic name for that secret, and the file name to write to. Monitor the process once again to confirm that the re-deployment has completed. Let's look at how this database file can be copied back to the local machine.

The oc rsync command uses the local rsync command if present on the clients Find centralized, trusted content and collaborate around the technologies you use most. In the next sections, I will demonstrate the usefulness of OpenShift's persistent volume framework by deploying a MySQL database, first without and then with persistent volume storage. 30.2. On an existing pod, you can also create a sidecar container with, e.g, busybox to mount the same PV and provide file copy tools if they're not present in the primary container. Fire up a terminal on the pod and use your favourite tools like ls and df to list files or see stats of the volume usage. Copying files to or from an OpenShift Container Platform container You can use the CLI to copy local files to or from a remote directory in a container using the rsync command. must still be satisfied in order for the PV and PVC to be bound, though the Some files, such as a databases backing store, may be written to in an almost constant stream. Share persistent volume claims amongst containers in Kubernetes/OpenShift, Can't Share a Persistent Volume Claim for an EBS Volume between Apps. If you are mounting a persistent volume into the container for your application and you need to copy files into it, then oc rsync can be used in the same way as described previously to upload files. oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --type pvc --claim-size=1G --mount-path /mnt. Check the contents of the current directory by running: You should see that the local machine now has a copy of the file. oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --mount-path /mnt. I recently implemented a complete backup solution for our Red Hat OpenShift clusters. When complete, you can validate that the files were transferred by listing the contents of the target directory inside of the container. NOTE: The communication between your cluster/API and your Webhook must be secured and with trusteable SSL certificates. To try it and our other tutorials without needing to install OpenShift, visit the OpenShift Learning Portal. example, rsync creates the destination directory if it does not exist and will Your data sits there.

The copy-files-to-volume Init container copies necessary files onto the PersistentVolume. This post is based on one of OpenShifts interactive learning scenarios. A service is not created, as we don't need the application we're running here (an instance of the Apache HTTPD server in this case) to actually be contactable. The openshift cluster install for 3.11 will ensure that credentials are provided and subsequently available on the nodes in the cluster to facilitate image pulling. If you already have an existing persistent volume claim, as we now do, you could mount the existing claimed volume against the dummy application instead. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. The PVC will only be able to bind to a PV that has the same name specified in Try, Buy, Sell Red Hat Hybrid Cloud Dot product of vector with camera's local positive x-axis? For more information on access modes, see the Kubernetes persistent volume documentation.

Connect and share knowledge within a single location that is structured and easy to search. You'll be using just the oc command line tool. but ordinary PVs and PVCs will have it set to "yes". The main application container utilizes these files at runtime for execution. It implies development changes: You need to apply the sidecar pattern to your custom templates (or the templates that come out of the box with OpenShift), custom resources, as the architecture of the solution needs that pattern to work. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. example, oc rsync creates the destination directory if it does not exist and sent 30 bytes received 40027 bytes 26704.67 bytes/sec total size is 39936 speedup is 1.00.

Part two will be about live synchronization. The files we copied to the persistent volume should again be visible. binds them together. When working with oc rsync, note the following: The oc rsync command uses the local rsync tool if present on the client the claim is paired with a volume that generally matches your request. . Traditionally, backup and restore operations involve two different layers. Other solutions need to install custom components (often a centralized control plane server and their own CLI tool). 31.1. Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. with manual invocations of oc rsync, such as --delete. The Configuring Clusters Your claim will remain As the templates are responsible for creating the ServiceAccount and assigning our custom ClusterRole to that ServiceAccount, you dont need extra commands to start the backup process (this does not change from what we have seen before, in the Backup point). Replace mysql|MYSQL with pgsql|PGSQL or The command for copying files from the local machine to the container needs to be of the form: oc rsync ./local/dir :/remote/dir.
