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. only sends files that are different between the source and the destination. Persistent Disk, Transferring Files In and Out of Containers in OpenShift This is part one of a three-part series. Traditionally, backup and restore operations involve two different layers. The command for copying files from the local machine to the container needs to be of the form: oc rsync ./local/dir :/remote/dir. A Persistent Volume (PV) enables you to keep state outside of your Pods, which means that your applications won't lose valuable data when a Pod fails or even your entire cluster. 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. Duress at instant speed in response to Counterspell. between the two is a process that matches a claim to an available volume and 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. Part one: Manually Copying Files 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). 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. Ceph What other topics would you like to see in the future on this blog? Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. Channel. Owner 65534 is not required for NFS exports. If you know exactly what PersistentVolume you want your In this post Graham will show the new persistent volumes features of version 1.1.3 of the All-in-One OpenShift virtual machine. Charlotte Ellett. A long-term solution for limiting who can claim a volume is in In Windows, the cwRsync client should be installed and added to the PATH for This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Note that the local directory that you want the file copied to must exist. Would the reflected sun's radiation melt ice in LEO? Part two will be about live synchronization. The PVs and PVCs where you This requires that the remote container also have the rsync command. An example download command is: ``` $ docker pull openshift/jenkins-2-centos7 ``` oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. In Find centralized, trusted content and collaborate around the technologies you use most. OpenShift Container Platform finds the volume backing the claim and mounts it into the pod. Therefore, you can control the behavior via the same flags used We're using the Apache HTTPD server purely as a means of keeping the pod running. label selector is ignored. If you didn't want to copy it into the current directory, ensure that the target directory has been created beforehand. We're not going to be using the web console, but you can check the status of your project there if you wish. 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. PVC will be bound regardless of whether the PV satisfies the PVCs label Why must a product of symmetric random variables be symmetric? Finally, in part three, we'll cover copying files into a new persistent volume. volumeName and claimRef are specified. The API introduces 2 types of resources: the directory does not exist, but rsync is used for copy, the directory is October 10, 2017 | by 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. Let's look at how this database file can be copied back to the local machine. to find the corresponding volume to mount. kubectl cp <file-spec-src> <file-spec-dest>. The MySQL pod must have a unique DATABASE_SERVICE_NAME. kubectl cp my-dir my-pod:my-dir. guide provides instructions for cluster administrators on provisioning an Clone your PVC as many times as you want. created for you. You can find a summary of the key commands covered below. kubectl cp my-file my-pod:my-file. projects: A PersistentVolume is a specific resource. In addition to uploading files into a running container, you might also want to download files. manually invoking oc rsync repeatedly, including any arguments normally passed 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. Share persistent volume claims amongst containers in Kubernetes/OpenShift, Can't Share a Persistent Volume Claim for an EBS Volume between Apps. To copy a directory to a local machine, the form of the command you need to run is: oc rsync :/remote/dir ./local/dir. Therefore, you can control the behavior via the same flags used 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. remote shell program to enable it to connect to the remote pod, and are an 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. Support for copying local files to or from a container is built into the CLI. Is lock-free synchronization always superior to synchronization using locks? Charlotte Ellett. you can use the below command to copy files from local to ocp PV. 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. 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). 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. is created locally and sent to the container where the tar utility is used to If Check the contents of the current directory by running: You should see that the local machine now has a copy of the file. 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. 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. This post is based on one of OpenShifts interactive learning scenarios. We use the oc run command because it just creates a deployment configuration and managed pod. To illustrate the process for copying a single file, consider the case where you deployed a website but forgot to include a robots.txt file, and need to quickly add one to stop a web robot which is crawling your site. 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. To copy a local directory to a pod directory: To copy a pod directory to a local directory: The oc rsync command exposes fewer command line options than standard rsync. With this Openshift Mymsql persistent storage won't mount on php, is docker storage driver a persistent storage. There's no reason to wait. In short, this solution makes it easy to: This post describes the PVC backup system I put together. If you're done with this persistent volume and perhaps needed to repeat the process with another persistent volume but with different data, you can unmount the persistent volume but retain the dummy application.
