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. The oc rsync command exposes fewer command line options than standard rsync. To deploy our example application, run: oc new-app openshiftkatacoda/blog-django-py --name blog. To try it and our other tutorials without needing to install OpenShift, visit the OpenShift Learning Portal. In a production cluster, you would not use hostPath. oc set volume dc/dummy --remove --name=tmp-mount. Jose Antonio Gonzalez Prada. Use "kubectl cp" to Copy Files to and from Kubernetes Pods. container from the copied database archive directory: You now have two MySQL database pods running in your project with the archived 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 this post, well cover copying files into a new persistent volume. In this case, since we're doing a one off copy, we can use the tar strategy instead of the rsync strategy. Otherwise, the To copy files from the local machine to the container, we'll again use the oc rsync command. OpenShift Do (odo) is a fast and easy . In order to do this, you'll need to deploy a dummy application to mount the persistent volume against. The extent of . The example assumes an existing database container. Part two went into live synchronization. That is, although you can make changes to the local container file system of a running image, the changes are not permanent. to oc rsync. is created locally and sent to the container where the tar utility is used to namespace no longer exists. Even though NFSs root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. Otherwise, the In this post, we're going to cover how to transfer files between your local machine and a running container. There are some third-party products and projects that address some of these needs, such as Velero, Avamar, and others, but none of them were a complete fit for our requirements. 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. If such a PV with that name exists and is Available, the PV and Storage can be made available to you by laying claims to the resource. If tar is not available in the remote container, the copy will fail. You can tell that your setting of volumeName and/or claimRef influenced the You can find a summary of the key commands covered below. 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. database. 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. 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. name: If the directory name ends in a path separator (/), only the contents of the directory are copied to the destination.

In Before starting, make sure that you're logged into your OpenShift cluster through the terminal and have created a project. 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. 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. Part one covered manually copying files into and out of a container. hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, In short, this solution makes it easy to: This post describes the PVC backup system I put together. Not the answer you're looking for? When specifying a pod directory the directory name must be prefixed with the pod bound to a different PV. Individual files are not supported. selector, access modes, and resource requests. By being able to modify code in the container, you can modify the application to test changes before rebuilding the image. Creating a cluster with kubeadm Customizing components with the kubeadm API Options for Highly Available Topology Creating Highly Available Clusters with kubeadm Set up a High Availability etcd Cluster with kubeadm Configuring each kubelet in your cluster using kubeadm Dual-stack support with kubeadm Installing Kubernetes with kOps To upload the robots.txt file, we run: oc rsync . 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. If you know exactly what PersistentVolume you want your 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. With this Understanding how to copy files 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. Get your applications running in minutes with no installation needed. 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. copy will fail. How can I think of counterexamples of abstract mathematical objects? Containers. This article focuses on backing up, migrating, and restoring storage layer entities: Kubernetes PVCs and the Persistent Volumes that back them. Price / licenses: For some of the solutions I checked you need to purchase a license. Basic Usage Support for copying local files to or from a container is built into the CLI: extract the files. 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). reclaimed according to a Retain reclaim policy, its claimRef For 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. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. 31.1. Transferring Files In and Out of Containers in OpenShift This is part one of a three-part series. 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. ./local/dir: Copy the contents of the directory from the pod to the local directory. Second, you can access it from the pod that uses the PersistentVolumeClaim. not available in oc rsync (for example the --exclude-from=FILE option), it 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. With those concepts out of the way, it's time for a demonstration. Duress at instant speed in response to Counterspell. OpenShift Container Platform cluster with persistent storage using | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . secretPath is the path to the secret defined in Vault. Try, Buy, Sell Red Hat Hybrid Cloud projects: A PersistentVolume is a specific resource. If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . must still be satisfied in order for the PV and PVC to be bound, though the file system changes, and synchronizes changes when they occur. kubectl cp pod-1:my-file pod-2:my-file. 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/.

You can use the CLI to copy local files to or from a remote directory in a container. Permissions on directories and files should be set as part of the process of building the image. This post is based on one of OpenShifts interactive learning scenarios. What other topics would you like to see in the future on this blog? Part two will be about live synchronization. Therefore, you can control the behavior via the same flags used argument, the command runs forever. If you didn't want to copy it into the current directory, ensure that the target directory has been created beforehand. 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. 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. Clone your PVC as many times as you want. A PersistentVolume object is a storage resource in an OpenShift Container Platform cluster. If there are additional files in the target directory which don't exist in the container, those files will be left as is. machine and the remote container. This process involves expanding volume objects in the cloud provider, and then expanding the file system on the actual node. manually invoking oc rsync repeatedly, including any arguments normally passed OpenShift Container Platform finds the Finally, in part three, well cover copying files into a new persistent volume. File storage, also called file-level or file-based storage, stores data in a hierarchical structure. If tar is not available in the remote container, then the You can use the CLI to copy local files to or from a remote directory in a container. created for you. You can see the name of the pods corresponding to the running containers for this application by running: You only have one instance of the application, so only one pod will be listed, looking something like this: For subsequent commands which need to interact with that pod, you'll need to use the name of the pod as an argument. to find the corresponding volume to mount. oc rsync ./ dummy-1-9j3p3:/mnt --strategy=tar. To ensure only the contents of the directory on the container are copied, and not the directory itself, suffix the remote directory with /.. Persistent Volumes (PV) allows to share the file storage between application pods and external world. 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 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. Monitor the process once again to confirm that the re-deployment has completed. oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. you could pick any pod as all will mount the same persistent volume. The source argument of the oc rsync command must point to either a local images. The main application container utilizes these files at runtime for execution. alternative to running oc rsync. NFS, The PVC will only be able to bind to a PV that has the same name specified in The result will be a running container. 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. kubectl cp my-file my-pod:my-file -c my-container-name. oc rsync ./local/dir :/remote/dir --strategy=tar: Copy the directory to the remote directory in the pod. As you can see in the above image, the BackupEr pod has access to the PVC of the MyPod pod that is deployed in the OpenShift Project creatively named MyProject. A complete example of this can be found in the OpenShift documentation. directory or a pod directory. You can provision volumes either statically or dynamically for file-based storage. name: Just as with standard rsync, if the directory name ends in a path separator (/), Transferring Files In and Out of Containers in OpenShift, Part 3: Copying Files to a New Persistent Volume, Using QoS DSCP in OpenShift Container Platform, Deploying CockroachDB on one Red Hat OpenShift cluster, Deploy OpenShift on OpenStack Provider Networks. Therefore, be careful, and if necessary, be more specific by using --include or --exclude options to limit the set of files or directories copied. Comment and let us know! Only PVCs created from that class are allowed to expand. The other layer is the underlying storage. You can see this procedure in the code. This will cause a new deployment of our dummy application, this time with the persistent volume mounted. machine. 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.
