OpenShift doesn't provide any specific features which will help you with doing that. directory and its contents are copied to the destination. 29.3. My solution is unsupported by Red Hat and it is not recommended for production use, but rather, is just to have a customizable solution in case the others doesn't fit you for any reason.You can reach other interesting solutions, based in an operator approach, in the OperatorHub.io like the etcd, whose operator is responsible for installing, backing up and restoring an etcd cluster (between many other cool features). Some files, such as a databases backing store, may be written to in an almost constant stream. you could pick any pod as all will mount the same persistent volume. This will cause a new deployment of our dummy application, this time with the persistent volume mounted. Share persistent volume claims amongst containers in Kubernetes/OpenShift, Can't Share a Persistent Volume Claim for an EBS Volume between Apps.

When using the --watch option, the behavior is effectively the same as Is storage in Openshift Online free tier actually persistent? 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. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. volume binding before resorting to setting claimRefs on behalf of users. the directory does not exist, but rsync is used for copy, the directory is This allows the claim to be used as a volume in a pod. In the case that you want to use a standard rsync command line option that is remote shell program to enable it to connect to the remote pod, and are an calls. extract the files. machine and the remote container. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. We are going to use one of the two types of Admission Webhooks, the Validating admission webhooks, that allow for the use of validating webhooks to enforce custom admission policies. kubectl cp my-pod:my-file my-file. This is part one of a three-part series. You can provision volumes either statically or dynamically for file-based storage. 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 copy-files-to-volume Init container copies necessary files onto the PersistentVolume. One example of where this might be done is during development when a dynamic scripting language is being used. oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. We can now copy some files into the persistent volume using the command: tar cf - . 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. When working with oc rsync, note the following: The oc rsync command uses the local rsync tool if present on the client We will discuss the security implications of this UID munging later in this post. 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. Clone your PVC as many times as you want. Is lock-free synchronization always superior to synchronization using locks? This requires that the remote container also have the rsync command. Let's look at how this database file can be copied back to the local machine. matching and binding process by inspecting a Bound PV and PVC pair for the Jose Antonio Gonzalez Prada. This paper explores how can we add a disk, create a file system on the immutable OS (RHCOS) in the OpenShift 4.x environment. 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. 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. 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. For If tar is not available in the remote container, the In Windows, the cwRsync client should be installed and added to the PATH for volumeName field. . Enable use of Minishift as staging setup for a proper OpenShift setup i.e. The first is the application layer. The --no-perms option tells oc rsync to not attempt to update permissions; this avoids it failing and returning errors. The tar copy method does not provide the same functionality as oc rsync. use with the oc rsync command. Part two will be about live synchronization. Elastic Block Store (EBS), and NFS mounts. The destination argument of the oc rsync command must point to a directory. It should be empty at this point. Admission webhooks call webhook servers to either mutate pods upon creation --such as to inject labels-- or to validate specific aspects of the pod configuration during the admission process. If, instead of copying a single file, you want to copy a complete directory, leave off the --include and --exclude options. 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). 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. argument, the command runs forever. For example: The architecture is relatively simple. In this post, well cover copying files into a new persistent volume. 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. Charlotte Ellett. The API introduces 2 types of resources: alternative to running oc rsync. secretKey is a key name within that secret. From within the interactive shell, see what files exist in the application directory. You can When BackupEr starts, it runs the backup.sh script to copy the data from MyPods source PVC to its own target PVC. 40 -rw-rw-r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. 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. database. GCE Get your applications running in minutes with no installation needed. oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --mount-path /mnt. the directory does not exist, but rsync is used for copy, the directory is request for a resource with specific attributes, such as storage size. A long-term solution for limiting who can claim a volume is in Would the reflected sun's radiation melt ice in LEO? You can tell that your setting of volumeName and/or claimRef influenced the Should I include the MIT licence of a library which I use from a CDN? 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. to oc rsync. Note: If the target directory contains existing files with the same name as a file in the container, the local file will be overwritten. Your data sits there. The copy-files-to-volume Init container copies files that are in /opt/app-root in the S2I builder image onto the Persistent Volume. oc rsync ./local/dir :/remote/dir --no-perms: Copy the directory to the remote directory in the pod. In addition to uploading files into a running container, you might also want to download files. 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. volumeName and claimRef are specified. Red Hat Training. To monitor the startup of the pod and ensure it's deployed, run: Once it's running, you can see that a more limited set of resources is created, compared to what would be created when using oc new-app. cases. 31.1. 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. The files we copied to the persistent volume should again be visible. 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. Kubernetes provides an API to separate storage from computation, i.e., a pod can perform computations while the files in use are stored on a separate resource. 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. How can I think of counterexamples of abstract mathematical objects? the 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. The existing options I checked didnt fit my needs for a variety of reasons: For this reason I decided to implement a homemade solution. Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. 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. The core component is a pod based on a custom container image. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. On the worker nodes, let's add an extra disk. 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. To copy files from the local machine to the container, we'll again use the oc rsync command. For an inside deployment I'd recommend you use a Service instead of a Route (the service must be secured with trusteable certs too). Find centralized, trusted content and collaborate around the technologies you use most. to oc rsync. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Owner 65534 is not required for NFS exports. Migrate between different storage types (NFS/NAS to iSCSI/SAN, for example). Pending until the PV is Available. kubectl cp /path/to/file my-pod:/path/to/file. Transferring Files In and Out of Containers in OpenShift This is part one of a three-part series. If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . In In this post, we'll cover manually copying files into and out of a container. To allow expansion of persistent volume claims (PVC) by OpenShift Container Platform users, OpenShift Container Platform administrators must create or update a StorageClass with allowVolumeExpansion set to true. according to the normal binding process. RBD, If you want to learn more or refresh your knowledge about persistent storage, check out the Persistent Storage topic in the OpenShift documentation. hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, OpenShift Container Platform clusters can be provisioned with persistent storage using GlusterFS. Otherwise, the The tar copy method does not provide the same functionality as rsync. may be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH To see more information on each oc command, run it with the --help option. Finally, in part three, well cover copying files into a new persistent volume. migration guide to find the exact commands for each of our supported database kubectl cp my-file my-pod:my-file. I recently implemented a complete backup solution for our Red Hat OpenShift clusters. A Red Hat training course is available for OpenShift Container Platform. Look for completion of the re-deployment: Check the contents of the target directory. By being able to modify code in the container, you can modify the application to test changes before rebuilding the image. There are at least 2 steps involved in scheduling your first container on a Openshift cluster. kubectl cp my-dir my-pod:my-dir. 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. 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. with manual invocations of oc rsync, such as --delete. We're using the Apache HTTPD server purely as a means of keeping the pod running. example : They intercept requests to the master API prior to the persistence of a resource, but after the request is authenticated and authorized. Persistent Volumes (PV) allows to share the file storage between application pods and external world. Sign up for the free trial of OpenShift Online. You can use the CLI to copy local files to or from a remote directory in a container. Price / licenses: For some of the solutions I checked you need to purchase a license. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. reclaimed according to a Retain reclaim policy, its claimRef 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. Permissions on directories and files should be set as part of the process of building the image. To learn more, see our tips on writing great answers. The ability to set claimRefs is a temporary workaround for the described use only send files that are different between the source and the destination. Deploy container and mount volume - CLI. 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. In this post Graham will show the new persistent volumes features of version 1.1.3 of the All-in-One OpenShift virtual machine. Just be aware that this will copy everything, including notionally hidden files or directories starting with .. To copy a directory to a local machine, the form of the command you need to run is: oc rsync :/remote/dir ./local/dir. namespace specified in claimRef. oc rsync :/remote/dir/. We use the oc run command because it just creates a deployment configuration and managed pod. 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 With those concepts out of the way, it's time for a demonstration. The --strategy=tar option indicates to use tar to copy the files rather than rsync. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. 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. If 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. to a new database containers persistent volume directory. What other topics would you like to see in the future on this blog? This means that, although the files can be added to the directory, permissions on existing directories cannot be changed. Do you have an OpenShift Online account? 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. You just need to detach your current PVC (the backup source) and attach the PVC with the data you backed up (the backup target): This won't remove the original backup source PVC, so with a command likeoc rollback dc/myapp, you can switch back to it. The other layer is the underlying storage. you can use the below command to copy files from local to ocp PV. PVC from binding to the specified PV before yours does. This process involves expanding volume objects in the cloud provider, and then expanding the file system on the actual node. You might call this an archive PV. During development, these may be data files or log files created by the application. This means that even if you have root access to the OCP node where the NFS mount point was provisioned, you likely wont have read/write permissions to files stored on that mount point. 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. iSCSI, use with the oc rsync command. Demo: Persistent volume storage in a MySQL database. machine. GlusterFS, 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. This is different than above, where we both claimed a new persistent volume and mounted it to the application at the same time. If rsync is not found locally or in the remote container, a tar archive 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. 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. Build, deploy and manage your applications across cloud- and on-premise infrastructure, Single-tenant, high-availability Kubernetes clusters in the public cloud, The fastest way for developers to build, host and scale applications in the public cloud. example, rsync creates the destination directory if it does not exist and will To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . not available in oc rsync (for example the --exclude-from=FILE option), it You can use the CLI to copy local files to or from a remote directory in a container. If you know exactly what PersistentVolume you want your Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. Users can copy the files to PV to make it available to the pods (for example configuration files), or pods can create the files to make it accessible outside the OpenShift cluster (for example log files). Now that the robots.txt file is uploaded, the request for it will succeed. To copy a single file from the container to the local machine, the form of the command you need to run is: oc rsync :/remote/dir/filename ./local/dir.
