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. Charlotte Ellett. Otherwise, the Part two will be about live synchronization. The example assumes an existing database container. using the rsync command. There's no reason to wait. Make sure that the storageClassName matches the storage class created in the last step: YAML apiVersion: v1 kind: PersistentVolumeClaim metadata: name: my-azurefile spec: accessModes: - ReadWriteMany storageClassName: my-azurefile resources: requests: storage: 100Gi Note In this post Graham will show the new persistent volumes features of version 1.1.3 of the All-in-One OpenShift virtual machine. projects: A PersistentVolume is a specific resource. This post is based on one of OpenShifts interactive learning scenarios. 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. The --no-perms option tells oc rsync to not attempt to update permissions; this avoids it failing and returning errors. GCE October 5, 2017 | by 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. The API introduces 2 types of resources: As already noted, it's not possible to copy a single file this way, so we indicate that the current directory should be copied, but use the --exclude=* option to first say that all files should be ignored when performing the copy. PersistentVolumeClaim to bind to, you can specify the PV in your PVC using the Edit /etc/origin/master/master-config.yaml and add the following: ValidatingAdmissionWebhook:configuration:apiVersion: v1disable: falsekind: DefaultAdmissionConfig. 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. During development, these may be data files or log files created by the application. In this post, well cover copying files into a new persistent volume. A PersistentVolume object is a storage resource in an OpenShift Container Platform cluster. Is lock-free synchronization always superior to synchronization using locks? For example: The architecture is relatively simple. Create the vault-database SecretProviderClass. images. 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. You can tell that your setting of volumeName and/or claimRef influenced the In addition to uploading files into a running container, you might also want to download files. The main application container utilizes these files at runtime for execution. Expanding Persistent Volume Claims with a File System. oc rsync ./local/dir :/remote/dir --no-perms: Copy the directory to the remote directory in the pod. 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. Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. To try it and our other tutorials without needing to install OpenShift, visit the OpenShift Learning Portal. 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. must still be satisfied in order for the PV and PVC to be bound, though the The MySQL pod must have a unique DATABASE_SERVICE_NAME. To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . Some files, such as a databases backing store, may be written to in an almost constant stream. but ordinary PVs and PVCs will have it set to "yes". If your application doesnt automatically detect new or changed files, you may need to notify it in some way to pick up the changes. Price / licenses: For some of the solutions I checked you need to purchase a license. Can I use a vintage derailleur adapter claw on a modern derailleur. Does Cast a Spell make you a spellcaster? Otherwise, the application developed on Minishift should be able to deployed on OpenShift online or similar. What other topics would you like to see in the future on this blog? The PVs and PVCs where 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. Now create a file named azure-file-pvc.yaml and copy in the following YAML. When specifying a pod directory the directory name must be prefixed with the pod Get your applications running in minutes with no installation needed. The core component is a pod based on a custom container image. If there is more than one container running within a pod, you'll need to specify which container you want to work with by using the --container option. With those concepts out of the way, it's time for a demonstration. The other layer is the underlying storage. oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --mount-path /mnt. $ 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. Therefore, you can control the behavior via the same flags used File storage, also called file-level or file-based storage, stores data in a hierarchical structure. OpenShift Container Platform finds the Why must a product of symmetric random variables be symmetric? This requires that the remote container also have the rsync command. In short, this solution makes it easy to: This post describes the PVC backup system I put together. not available in oc rsync, for example the --exclude-from=FILE option, it alternative to running oc rsync. 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. kubectl cp my-file my-pod:my-file -c my-container-name. 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). 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. Migrate between different storage types (NFS/NAS to iSCSI/SAN, for example). Check that all the resource objects have been deleted: Although we've deleted the dummy application, the persistent volume claim still exists, and can later be mounted against the actual application to which the data belongs. This paper explores how can we add a disk, create a file system on the immutable OS (RHCOS) in the OpenShift 4.x environment. 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 existing options I checked didnt fit my needs for a variety of reasons: For this reason I decided to implement a homemade solution. and In In the upcoming OpenShift 4.8 release, our teamwill deliver complete provider networks support when deploying on Red Hat OpenStack. You can see this procedure in the code.

Clone your PVC as many times as you want. Finally, in part three, we'll cover copying files into a new persistent volume. Enable use of Minishift as staging setup for a proper OpenShift setup i.e. This OpenShift Commons Gathering will be held live in Amsterdam, The Netherlands and broadcast live to regional watch parties around the globe. request for a resource with specific attributes, such as storage size. Clash between mismath's \C and babel with russian, Story Identification: Nanomachines Building Cities. 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. 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. Do you have an OpenShift Online account? Using the --watch option causes the command to monitor the source path for any Even though NFSs root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. This process involves expanding volume objects in the cloud provider, and then expanding the file system on the actual node. 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. Elastic Block Store (EBS), and NFS mounts. To learn more, see our tips on writing great answers. file system changes, and synchronizes changes when they occur. AWS EBS, Therefore, to avoid these scenarios and The oc rsync command exposes fewer command line options than standard rsync. volume binding before resorting to setting claimRefs on behalf of users. That is, although you can make changes to the local container file system of a running image, the changes are not permanent. 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/. Only PVCs created from that class are allowed to expand. We can now copy some files into the persistent volume using the command: tar cf - . This is part one of a three-part series. 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. your claim so that nobody elses claim can bind to it before yours does. If tar is not available in the remote container, the PersistentVolume objects from sources such as GCE Persistent Disk, AWS A Red Hat training course is available for OpenShift Container Platform. Even though NFS's root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. guide provides instructions for cluster administrators on provisioning an To try it and our other tutorials without needing to install OpenShift, visit https://learn.openshift.com. Containers. Individual files are not supported. Individual files are not currently supported. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . I recently implemented a complete backup solution for our Red Hat OpenShift clusters. You'll be using just the oc command line tool. Products Ansible.com Learn about and try our IT automation product. directory and its contents are copied to the destination. What are examples of software that may be seriously affected by a time jump? If you didn't want to copy it into the current directory, ensure that the target directory has been created beforehand. With this mongodb|MONGODB and refer to 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. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. namespace specified in claimRef. Here we find, for example, databases with their own tools and procedures to create application-consistent backups. To see more information on each oc command, run it with the --help option. 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. Owner 65534 is not required for NFS exports. manually invoking oc rsync repeatedly, including any arguments normally passed directory or a pod directory. You can request storage by creating PersistentVolumeClaim objects in your 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. the 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. PVC from binding to the specified PV before yours does. 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. The first is the application layer. 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. Fibre To create a dummy application for this purpose, run this command: oc run dummy --image centos/httpd-24-centos7. oc rsync ./ dummy-1-9j3p3:/mnt --strategy=tar. You can 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. In this case, since we're doing a one off copy, we can use the tar strategy instead of the rsync strategy. This will cause a new deployment of our dummy application, this time with the persistent volume mounted. volumeName. For more information on access modes, see the Kubernetes persistent volume documentation. OpenShift doesn't provide any specific features which will help you with doing that. 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. GlusterFS, Openshift Mymsql persistent storage won't mount on php, is docker storage driver a persistent storage. 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. . secretPath is the path to the secret defined in Vault. oc rsync :/remote/dir/. CentOS7 based image The v3.x images are available on DockerHub. This post is based on one of OpenShifts interactive learning scenarios. to find the corresponding volume to mount. In Windows, the cwRsync client should be installed and added to the PATH for claim with the given name in the same namespace as the pod, then uses the claim The copy-files-to-volume Init container copies necessary files onto the PersistentVolume. blog-1-9j3p3:/opt/app-root/src/htdocs --exclude=* --include=robots.txt --no-perms. Using the --watch option causes the command to monitor the source path for any When using the --watch option, the behavior is effectively the same as 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. Support for copying local files to or from a container is built into the CLI. From within the interactive shell, see what files exist in the application directory. Security, 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. The result will be a running container. In addition to copying a single file, a directory can also be copied. 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. At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. Before starting, make sure that you're logged into your OpenShift cluster through the terminal and have created a project. Comment and let us know! Making statements based on opinion; back them up with references or personal experience. We're using the Apache HTTPD server purely as a means of keeping the pod running. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. iSCSI, the directory does not exist, but rsync is used for copy, the directory is First, find out your pvc's mountPath. use with the oc rsync command. 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. If you know exactly what PersistentVolume you want your Would the reflected sun's radiation melt ice in LEO? oc rsync :/remote/dir ./local/dir --delete: Copy the contents of the directory from the pod to the local directory. 40 -rw-rw-r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. Integral with cosine in the denominator and undefined boundaries. 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. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. You can find a summary of the key commands covered below. alternative to running oc rsync. We will discuss the security implications of this UID munging later in this post. 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 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 have a few options. We're happy to make tutorials about anything that helps you with your OpenShift experience. Describing best practices for backing up open files and databases is out of the scope of this article, but we tend to use the databases native tools for backing up & restoring (e.g., mysqldump, pg_dump, etc.). Overview. Am I being scammed after paying almost $10,000 to a tree company not being able to withdraw my profit without paying a fee, Parent based Selectable Entries Condition. If copy will fail. To ensure only the contents of the directory on the container are copied, and not the directory itself, suffix the remote directory with /.. You can use the CLI to copy local files to or from a remote directory in a container. example : You can find a summary of the key commands covered below. Your claim will remain In This process usually involves expanding volume objects in the CloudProvider, and then expanding the file system on the actual node. Unlike when copying from the container to the local machine, there's no form for copying a single file. In this post, you've learned about oc commands that you can use to copy files into a persistent volume. might be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH 1 Answer Sorted by: 1 Mount the PV in a different pod, and "oc cp" the files in, or "oc rsh ." and curl/wget/scp from inside the pod to the local volume mount. How can I think of counterexamples of abstract mathematical objects? are not in the local directory. volumeName and claimRef are specified. 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. The PVCs access modes and resource requests 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. Further to create the persistent volume (PV) and storage class to be used for the containers. this case, the administrator can specify the PVC in the PV using the claimRef RBD, We're not going to be using the web console, but you can check the status of your project there if you wish. Traditionally, backup and restore operations involve two different layers. label selector is ignored. 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. Permissions on directories and files should be set as part of the process of building the image. 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. is created locally and sent to the container where the tar utility is used to 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.
