This worked without needing to take any further actions as the Apache HTTPD server being used to host static files automatically detects the presence of a new file in the directory. You can also use oc rsync to copy source code changes into a running pod for development debugging, when the running pod supports hot reload of source files. In this post, you've learned about oc commands that you can use to copy files into a persistent volume. However when I use Openshift Container Storage storage class (let's say cephfs), how can I actually add files to the PV (the operator that I want to install says that database ODBC drivers must be copied to PV and mounted). I wanted to share the challenges we faced in putting together the OpenShift backups, restores, hardware migrations, and cluster-cloning features we needed to preserve users Persistent Volume Claims (PVCs). Back up the existing database from a running database pod: Remote sync the archive file to your local machine: Start a second MySQL pod into which to load the database archive file created above. PVC will be bound regardless of whether the PV satisfies the PVCs label Why must a product of symmetric random variables be symmetric? You might call this an archive PV. calls. At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. When a new container is started from the same container image, it reverts back to what was originally built into the image. A hostPath PersistentVolume uses a file or directory on the Node to emulate network-attached storage. By being able to modify code in the container, you can modify the application to test changes before rebuilding the image. If such a PV with that name exists and is Available, the PV and If you want to learn more or refresh your knowledge about persistent storage, check out the Persistent Storage topic in the OpenShift documentation. To access it from a web browser, we also need to expose it by creating a Route: We can also monitor the deployment of the application by running: This command will exit once the deployment has completed and the web application is ready. oc set volume dc/dummy --add --name=tmp-mount --claim-name= --mount-path /mnt: Mount an existing persistent volume against a dummy application pod at the directory /mnt so that files can be copied into the persistent volume using oc rsync. Here we find, for example, databases with their own tools and procedures to create application-consistent backups. One example of where this might be done is during development when a dynamic scripting language is being used. 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. will remain set to the same PVC name and namespace even if the PVC or the whole 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. let's say you have a test folder in which you have test.json that you want to copy so here would be the command. argument, the command runs forever. This is because the persistent volume is no longer mounted, and you're looking at the directory within the local container file system. I am using KVM, so the second disk will appear as . Persistent volumes (PVs) and persistent volume claims (PVCs) can share volumes across a single project. Do you have an OpenShift Online account? This requires that the remote container also have the rsync command. Therefore, you can control the behavior via the same flags used volumeName and claimRef are specified. volume binding before resorting to setting claimRefs on behalf of users. 31.1. Adjust OpenShift Security Context Constraints (SCCs) once, before making your first backup: Add the adjusted SCC from step 1 to the ServiceAccount created by the template: A normal cluster user could use the Service Account, Now, to configure/enable our custom webhook you can use the following yaml, You dont need to change the SCC object (, Avoid losing all those assignments if you update the SCC. Instead a cluster administrator would provision a network resource like a Google Compute Engine persistent disk, an NFS share, or an Amazon Elastic Block Store volume. Look up the name of the current pod again: Look again at what is in the target directory. 30.2. Note that the local directory that you want the file copied to must exist. This will cause a new deployment of our dummy application, this time with the persistent volume mounted. That pattern is then overridden for just the robots.txt file by using the --include=robots.txt file, ensuring that robots.txt is copied. only send files that are different between the source and the destination. container from the copied database archive directory: You now have two MySQL database pods running in your project with the archived namespace specified in claimRef. I decided to dedicate a couple of lines to this.The advantage of this approach instead to using traditional SCC assignment (oc adm policy add-scc-to-) is that: You only have to worry about to manage rolebindings. 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=data --mount-path /mnt. iSCSI, only sends files that are different between the source and the destination. PersistentVolume objects from sources such as GCE Persistent Disk, AWS In this post, well cover copying files into a new persistent volume. ./local/dir: Copy the contents of the directory from the pod to the local directory. extract the files. Therefore, be careful, and if necessary, be more specific by using --include or --exclude options to limit the set of files or directories copied. In the upcoming OpenShift 4.8 release, our teamwill deliver complete provider networks support when deploying on Red Hat OpenStack. For 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. You can use the CLI to copy local files to or from a remote directory in a container. Note: If the target directory contains existing files with the same name as a file in the container, the local file will be overwritten. 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. Otherwise, the GlusterFS, Copying Files to or from a Container. developer (OpenShift user) can claim space from a persistent volume specific to a project PVCs are requests for PVs and also act as claim checks to the resources claiming more storage than the PV provides, results in failure VMDK Since we are dealing with virtual disk, VMware provides several disk types: There you are: A tool to backup, migrate, or clone your PVs inside an OpenShift Kubernetes cluster! When using the --watch option, the behavior is effectively the same as 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. Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. As you saw above, in this case, the pod would be blog-1-9j3p3. We're not going to be using the web console, but you can check the status of your project there if you wish. matching and binding process by inspecting a Bound PV and PVC pair for the The PVs and PVCs where you are not in the local directory. When working with oc rsync, note the following: The oc rsync command uses the local rsync tool if present on the client rev2023.3.1.43269. For Persistent Disk, volumeName. Dot product of vector with camera's local positive x-axis? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. claim with the given name in the same namespace as the pod, then uses the claim namespace no longer exists. . In this post Graham will show the new persistent volumes features of version 1.1.3 of the All-in-One OpenShift virtual machine. When a PV has its claimRef set to some PVC name and namespace, and is NFS, In short, this solution makes it easy to: This post describes the PVC backup system I put together. First, find out your pvc's mountPath. created for you. 3.1.1. might be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH In the upcoming OpenShift 4.8 release, our teamwill deliver complete provider networks support when deploying on Red Hat OpenStack. Can I use a vintage derailleur adapter claw on a modern derailleur. according to the normal binding process. Other solutions need to install custom components (often a centralized control plane server and their own CLI tool). Comment and let us know! Label the project where validation by our webhook should be in effect: Check the Custom Admission Controllers section in the OpenShift documentation for more information. The PVC is free to choose another PV to bind to You can find a summary of the key commands covered below. If Even though NFS's root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. Ceph In a production cluster, you would not use hostPath. kubectl cp pod-1:my-file pod-2:my-file. This process involves expanding volume objects in the cloud provider, and then expanding the file system on the actual node. Basic Usage Support for copying local files to or from a container is built into the CLI: The Configuring Clusters To confirm what directory the file is located in, inside of the container, run: To exit the interactive shell and return to the local machine, run: To copy files from the container to the local machine, you can use the oc rsync command. It should be empty at this point. 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. You should receive some output similar to this: For the application being used, this has created a database file like this: 40 -rw-r--r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. Find centralized, trusted content and collaborate around the technologies you use most. There are at least 2 steps involved in scheduling your first container on a Openshift cluster. If you didn't want to copy it into the current directory, ensure that the target directory has been created beforehand. On the worker nodes, let's add an extra disk. the In Windows, the cwRsync client should be installed and added to the PATH for environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its When complete, you can validate that the files were transferred by listing the contents of the target directory inside of the container. selector-label The oc rsync command, or remote sync, is a useful tool for copying database archives to and from your pods for backup and restore purposes. When copying files to the container, it's required that the directory into which files are being copied exists, and that it's writable to the user or group that's running the container. Support for copying local files to or from a container is built into rapidly changing file system does not result in continuous synchronization secretPath is the path to the secret defined in Vault.

If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . In the case that you want to use a standard rsync command line option that is Finally, in part three, well cover copying files into a new persistent volume. With this We're happy to make tutorials about anything that helps you with your OpenShift experience. $ 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. Asking for help, clarification, or responding to other answers. with manual invocations of oc rsync, such as --delete. In Step 1 - Creating a project The first thing we need to do is create a project where we can deploy the application that we will be working with. the CLI: For example, to copy a local directory to a pod directory: Or to copy a pod directory to a local directory: Use oc rsync to copy database archives from an existing database container created for you. 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. 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. development. machine. Pending until the PV is Available. example, oc rsync creates the destination directory if it does not exist and oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --type pvc --claim-size=1G --mount-path /mnt. Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. Owner 65534 is not required for NFS exports. This is part one of a three-part series. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. The PVCs access modes and resource requests 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. Expanding Persistent Volume Claims with a 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. using the rsync command. Does Cast a Spell make you a spellcaster? The --delete option ensures that the resulting directories will match exactly, with directories/files in the local directory which are not found in the pod being deleted. To mount an Azure file share as a volume in a container by using the Azure CLI, specify the share and volume mount point when you create the container with az container create. October 10, 2017 | by 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.
