openshift copy file to persistent volume
PersistentVolume objects from sources such as GCE Persistent Disk, AWS with manual invocations of oc rsync, such as --delete. When BackupEr starts, it runs the backup.sh script to copy the data from MyPods source PVC to its own target PVC. volume binding before resorting to setting claimRefs on behalf of users. Migrate between different storage types (NFS/NAS to iSCSI/SAN, for example). . Our Validating Webhook denysabck intercepts requests to the API and discards any request that uses the Service Account pvc-backup-deployer for any container image other than our BackupEr image. Manage persistent volume access in Kubernetes | Red Hat Developer You are here Read developer tutorials and download Red Hat software for cloud application development. OpenShift Container Platform cluster with persistent storage using using the rsync command. and To copy only selected files, you'll need to use the --exclude and --include options to filter what is and isn't copied from the specified directory. 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. reclaimed according to a Retain reclaim policy, its claimRef Part one covered manually copying files into and out of a container. You can tell that your setting of volumeName and/or claimRef influenced the extract the files. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Even though NFS's root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. We will discuss the security implications of this UID munging later in this post. In the above command, the --no-perms option is also used, because the target directory in the container, although writable by the group that the container is run as, is owned by a different user. In addition to uploading files into a running container, you might also want to download files. In the upcoming OpenShift 4.8 release, our teamwill deliver complete provider networks support when deploying on Red Hat OpenStack. Expanding persistent volume claims (PVCs) with a file system Expanding PVCs based on volume types that need file system resizing, such as GCE PD, EBS, and Cinder, is a two-step process. make a request for storage resources using a PersistentVolumeClaim object; Second, you can access it from the pod that uses the PersistentVolumeClaim. created for you. PersistentVolumeClaim to bind to, you can specify the PV in your PVC using the To copy the media directory from the container for our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/media . Comment and let us know! For example: The architecture is relatively simple. Set the spec.nodeName of the BackupEr pod to the desired OCP node. We're happy to make tutorials about anything that helps you with your OpenShift experience. That is, although you can make changes to the local container file system of a running image, the changes are not permanent. If you want to learn more or refresh your knowledge about persistent storage, check out the Persistent Storage topic in the OpenShift documentation. 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. kubectl cp my-dir my-pod:my-dir. Only PVCs created from that class are allowed to expand. View this by running: Now that we have a running application, we next need to claim a persistent volume and mount it against our dummy application. 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. 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. This allows the claim to be used as a volume in a pod. This process usually involves expanding volume objects in the CloudProvider, and then expanding the file system on the actual node. ./local/dir: Copy the contents of the directory from the pod to the local directory. your claim so that nobody elses claim can bind to it before yours does. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Duress at instant speed in response to Counterspell. Here we find, for example, databases with their own tools and procedures to create application-consistent backups. container from the copied database archive directory: You now have two MySQL database pods running in your project with the archived oc rsync
:/remote/dir/. PVC will be bound regardless of whether the PV satisfies the PVCs label 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. 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). The backup.sh script then uses this SUID sed to arrange file access from the source to the target PVC: NOTE: You can see the complete Dockerfile and script at following URLs:- Dockerfile- backup.sh. to find the corresponding volume to mount. oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. Do you have an OpenShift Online account? directory or a pod directory. Making statements based on opinion; back them up with references or personal experience. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. A Red Hat training course is available for OpenShift Container Platform.

When working with oc rsync, note the following: The oc rsync command uses the local rsync tool if present on the client We mount the persistent volume at /mnt inside of the container, which is the traditional directory used in Linux systems for temporarily mounting a volume. Thanks for contributing an answer to Stack Overflow! To copy the complete contents of a directory to the htdocs directory in the container, you could run: oc rsync images blog-1-9j3p3:/opt/app-root/src/htdocs --no-perms. Pending until the PV is Available. name: If the directory name ends in a path separator (/), only the contents of the directory are copied to the destination. 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. Just make sure that an image your pod container is using has all the tools you need. Finally, in part three, well cover copying files into a new persistent volume. Openshift Mymsql persistent storage won't mount on php, is docker storage driver a persistent storage. OpenShift Container Platform clusters can be provisioned with persistent storage using GlusterFS. We're happy to make tutorials about anything that helps you with your OpenShift experience. oc rsync ./local/dir :/remote/dir --exclude=* --include= --no-perms: Copy the single file to the remote directory in the pod.

It can also be used to copy source code changes into a running pod for development debugging, when the running pod supports hot reload of source files. Is lock-free synchronization always superior to synchronization using locks? The result will be a running container. Using the --watch option causes the command to monitor the source path for any This process involves expanding volume objects in the cloud provider, and then expanding the file system on the actual node. I recently implemented a complete backup solution for our Red Hat OpenShift clusters. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. This post is based on one of OpenShifts interactive learning scenarios. This is part one of a three-part series. To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . GlusterFS, By being able to modify code in the container, you can modify the application to test changes before rebuilding the image. 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. directory and its contents are copied to the destination. Owner 65534 is not required for NFS exports. manually invoking oc rsync repeatedly, including any arguments normally passed This requires that the remote container also have the rsync command. Persistent volumes (PVs) and persistent volume claims (PVCs) can share volumes across a single project. 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. You may also want your cluster administrator to "reserve" the volume for only matching and binding process by inspecting a Bound PV and PVC pair for the name: Just as with standard rsync, if the directory name ends in a path separator (/), For more information on access modes, see the Kubernetes persistent volume documentation. To try it and our other tutorials without needing to install OpenShift, visit the OpenShift Learning Portal.

This will cause a new deployment of our dummy application, this time with the persistent volume mounted. 3.1. Expanding Persistent Volume Claims with a File System. Part two went into live synchronization. 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. database. From within the interactive shell, see what files exist in the application directory. 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. Find centralized, trusted content and collaborate around the technologies you use most. remote shell program to enable it to connect to the remote pod, and are an OpenShift Container Platform finds the volume backing the claim and mounts it into the pod. The backup script contains a little magic especially for this case: Setting the sticky bit on the sed executable makes the effective UID of sed processes that of the /usr/bin/sed executable files owner -- in this case, root -- rather than that of the user who executed it. Note: If the target directory contains existing files with the same name as a file in the container, the local file will be overwritten. will be created locally and sent to the container where tar will be used to The cluster administrator should first consider configuring selector, access modes, and resource requests. In addition to copying a single file, a directory can also be copied. are not in the local directory. When specifying a pod directory the directory name must be prefixed with the pod The other layer is the underlying storage. You can provision volumes either statically or dynamically for file-based storage. set the volumeName and/or claimRef yourself will have no such annotation, Traditionally, backup and restore operations involve two different layers. You can request storage by creating PersistentVolumeClaim objects in your use with the oc rsync command. will remain set to the same PVC name and namespace even if the PVC or the whole Would the reflected sun's radiation melt ice in LEO? Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. Therefore, to avoid these scenarios and to oc rsync. 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: may be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH You can find a summary of the key commands covered below. request for a resource with specific attributes, such as storage size. mongodb|MONGODB and refer to file system changes, and synchronizes changes when they occur. If rsync is not found locally or in the remote container, a tar archive The docker image doesn't need to run as root, but it requires a small but important trick before it is executed: You must have an OCP cluster running OpenShift version 3.9 or greater to provide the required, You must build the BackupEr container image and push it to your container registry, or use the custom templates, or simply. extract the files. Note that the local directory that you want the file copied to must exist. but ordinary PVs and PVCs will have it set to "yes". If you wanted to rename the directory at the time of copying it, you should first create the target directory with the name you want to use: Then, to copy the files, use this command: oc rsync blog-1-9j3p3:/opt/app-root/src/media/. When copying a directory, you can be more selective about what is copied by using the --exclude and --include options to specify patterns to be matched against directories and files, with them being excluded or included as appropriate. To copy files from the local machine to the container, we'll again use the oc rsync command. Get your applications running in minutes with no installation needed. Look for completion of the re-deployment: Check the contents of the target directory. 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. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, Openshift Container Storage - copy file to persistent volume, The open-source game engine youve been waiting for: Godot (Ep. 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. First, we create a robots.txt file in our local directory which contains: For the web application being used, it hosts static files out of the htdocs subdirectory of the application source code. In a production cluster, you would not use hostPath. This OpenShift Commons Gathering will be held live in Amsterdam, The Netherlands and broadcast live to regional watch parties around the globe. There are at least 2 steps involved in scheduling your first container on a Openshift cluster. calls. Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. The PVCs access modes and resource requests On the worker nodes, let's add an extra disk. A PersistentVolumeClaim is a volumeName and claimRef are specified. With this We have been able to see during the reading of all the chapters how I faced the challenge to implement backup-restore / migration capabilities in an OpenShift cluster with my artisanal solution. 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. 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. 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. A hostPath PersistentVolume uses a file or directory on the Node to emulate network-attached storage. Can I use a vintage derailleur adapter claw on a modern derailleur. When a new container is started from the same container image, it reverts back to what was originally built into the image. Specifying a claimRef in a PV does not prevent the specified PVC from being This is a useful tool for copying database archives to and from your pods for backup and restore purposes. The following YAML can be used to create a persistent volume claim 5 GB in size with ReadWriteMany access, using the built-in storage class. Should I include the MIT licence of a library which I use from a CDN? | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . 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 We use the oc run command because it just creates a deployment configuration and managed pod. with manual invocations of oc rsync, such as --delete. You can use the CLI to copy local files to or from a remote directory in a container. 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.
