Specifying a claimRef in a PV does not prevent the specified PVC from being After you have authenticated to your OpenShift cluster, select to create a new project and name it pdfrack as shown in the following image: If you are more of a command line person, the command would be: If rsync is not found locally or in the remote container, a tar archive If tar is not available in the remote container, the manually invoking oc rsync repeatedly, including any arguments normally passed Price / licenses: For some of the solutions I checked you need to purchase a license. Although any changes to the local container file system are discarded when the container is stopped, it can sometimes be convenient to be able to upload files into a running container. Try, Buy, Sell Red Hat Hybrid Cloud Let's look at how this database file can be copied back to the local machine. Mount the PV in a different pod, and "oc cp" the files in, or "oc rsh " and curl/wget/scp from inside the pod to the local volume mount. When you're done and want to delete the dummy application, use oc delete to delete it, using a label selector of run=dummy to ensure we only delete the resource objects related to the dummy application. To create an interactive shell within the same container running the application, you can use the oc rsh command, supplying it the environment variable holding the name of the pod. name: Just as with standard rsync, if the directory name ends in a path separator (/), Traditionally, backup and restore operations involve two different layers. and Channel. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Otherwise, the Demo: Persistent volume storage in a MySQL database. secretKey is a key name within that secret. ./local/dir: Copy the contents of the directory from the pod to the local directory. If you've followed the security recommendations to setup an NFS server to provision persistent storage to your OpenShift Container Platform (OCP) cluster, the owner ID 65534 is used as an example. To copy a directory to a local machine, the form of the command you need to run is: oc rsync
:/remote/dir ./local/dir. BackupEr also has its own PVC. To demonstrate transferring files to and from a running container, we first need to deploy an application. Undo working copy modifications of one file in Git? Within the ecosystem of Red Hat OpenShift Networking is a new security-focused operator named Ingress Node Firewall that uses an extended Berkeley Packet Filter (eBPF) and eXpress Data Path (XDP) How to backup, clone and migrate Persistent Volume Claims on OpenShift, example of this can be found in the OpenShift documentation, Join OpenShift Commons Gathering at KubeCon EU, April 18, 2023, Your Guide to security hardening OpenShift using the compliance operator, OpenShift 4.12: Ingress Node Firewall Operator. Would the reflected sun's radiation melt ice in LEO? You can tell whether a claim or volume is bound by querying using the CLI: A PersistentVolumeClaim is used by a pod as a volume. Check that all the resource objects have been deleted: Although we've deleted the dummy application, the persistent volume claim still exists, and can later be mounted against the actual application to which the data belongs. In OpenShift (with cluster-admin or similar privileges for steps 1 and 2, and oc adm command from step 3): To perform a PVC backup, deploy the BackupEr pod: #### ex How to backup a SAN/iSCSI PVCoc new-app --template=backup-block \-p PVC_NAME=pvc-to-backup \-p PVC_BCK=pvc-for-backuper \-p NODE=node1.mydomain.com, #### ex How to backup a NAS/NFS PVC oc new-app --template=backup-shared \ -p PVC_NAME=pvc-to-backup \ -p PVC_BCK=pvc-for-backuper.

The PVs and PVCs where you The core component is a pod based on a custom container image. If you want an exact copy, and to have the target directory always updated to be exactly the same as what exists in the container, use the --delete option with oc rsync. To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . The --no-perms option ensures that no attempt is made to transfer permissions, which can fail if remote directories are not owned by the user that the container runs as. When doing this, we assign it a claim name of data so that we can refer to the claim by a set name later on. If rsync is not found locally or in the remote container, then a tar archive 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. example, rsync creates the destination directory if it does not exist and will You'll be using just the oc command line tool. Storage is provisioned by your cluster administrator by creating PersistentVolume objects from sources such as GCE Persistent Disk, AWS Elastic Block Store (EBS), and NFS mounts. In a production cluster, you would not use hostPath. Jose Antonio Gonzalez Prada. If youve been reading closely, you may have noticed that this solution is suitable only in fairly controlled cluster environments, because it has some security caveats: This is where Admission Webhooks come in handy. If you know exactly what PersistentVolume you want your with manual invocations of oc rsync, such as --delete. Not the answer you're looking for? The API introduces 2 types of resources: the directory does not exist, but rsync is used for copy, the directory is In order to do this, you'll need to deploy a dummy application to mount the persistent volume against. example, oc rsync creates the destination directory if it does not exist and binds them together. 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. This is because the persistent volume is no longer mounted, and you're looking at the directory within the local container file system. You can use a mix of your databases backup tooling with the solution described in this article to get complete backups of database snapshots as part of the backup of Persistent Volumes. 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. Using the --watch option causes the command to monitor the source path for any Fibre When specifying a pod directory the directory name must be prefixed with the pod . The files we copied to the persistent volume should again be visible. The example assumes an existing database container. rapidly changing file system does not result in continuous synchronization We're happy to make tutorials about anything that helps you with your OpenShift experience. Storage can be made available to you by laying claims to the resource. 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. argument, the command runs forever. If Get your applications running in minutes with no installation needed. kubectl cp my-file my-pod:my-file -c my-container-name.

Storage is provisioned by your cluster administrator by creating The ability to set claimRefs is a temporary workaround for the described use Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. You can oc set volume dc/dummy --remove --name=tmp-mount. Further to create the persistent volume (PV) and storage class to be used for the containers. You can use the CLI to copy local files to or from a remote directory in a container. At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. To try it and our other tutorials without needing to install OpenShift, visit https://learn.openshift.com. Other solutions need to install custom components (often a centralized control plane server and their own CLI tool). OpenShift doesn't provide any specific features which will help you with doing that. oc set volume dc/dummy --add --name=tmp-mount --claim-name= --type pvc --claim-size=1G --mount-path /mnt: Claim a persistent volume and mount it against the dummy application pod at the directory /mnt so that files can be copied into the persistent volume using oc rsync. On the worker nodes, let's add an extra disk. We're using the Apache HTTPD server purely as a means of keeping the pod running. Backing up these files requires more consideration than backing up files that change less frequently, such as documents, pictures, or finished sound and video used for playback. machine. Weve seen interesting things that come out-of-the-box with OpenShift, like the use of WebHooks and the Role-Based Access to SCCs, and how they can help you to implement cool and secured custom applications. You can find a summary of the key commands covered below. to oc rsync. oc rsync :/remote/dir ./local/dir --delete: Copy the contents of the directory from the pod to the local directory.

One example of where this might be done is during development when a dynamic scripting language is being used. directory or a pod directory. Use "kubectl cp" to Copy Files to and from Kubernetes Pods. In addition to copying a single file, a directory can also be copied. Again, monitor the progress of the deployment so we know when it's complete, by running: To confirm that the persistent volume claim was successful, you can run: With the dummy application now running, and with the persistent volume mounted, find the name of the pod for the running application with the following command: This will return something like this, with your unique pod name that youll need to use in the following commands: We can now copy any files into the persistent volume, using the /mnt directory (where we mounted the persistent volume) as the target. I recently implemented a complete backup solution for our Red Hat OpenShift clusters. move to the folder from which you want to copy the file. PersistentVolume objects from sources such as GCE Persistent Disk, AWS Is lock-free synchronization always superior to synchronization using locks? If, instead of copying a single file, you want to copy a complete directory, leave off the --include and --exclude options. You can tell that your setting of volumeName and/or claimRef influenced the An example download command is: ``` $ docker pull openshift/jenkins-2-centos7 ``` That pattern is then overridden for just the robots.txt file by using the --include=robots.txt file, ensuring that robots.txt is copied. Pending until the PV is Available. In this post, we're going to cover how to transfer files between your local machine and a running container. There's no reason to wait.
