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. namespace specified in claimRef. Transferring Files In and Out of Containers in OpenShift This is part one of a three-part series. 30.2. You can use the CLI to copy local files to or from a remote directory in a container Integral with cosine in the denominator and undefined boundaries. PersistentVolume objects from sources such as GCE Persistent Disk, AWS argument, the command runs forever. Backup that PV with our custom solution. and We use the oc run command because it just creates a deployment configuration and managed pod. 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. not available in oc rsync, for example the --exclude-from=FILE option, it They intercept requests to the master API prior to the persistence of a resource, but after the request is authenticated and authorized. 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. kubectl cp pod-1:my-file pod-2:my-file. Set the spec.nodeName of the BackupEr pod to the desired OCP node. 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. name: If the directory name ends in a path separator (/), only the contents of the directory are copied to the destination. 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. Demo: Persistent volume storage in a MySQL database. This pod is responsible for running the backup script. Using the --watch option causes the command to monitor the source path for any Specifying a claimRef in a PV does not prevent the specified PVC from being Permissions on directories and files should be set as part of the process of building the image. kubectl cp my-pod:my-file my-file. machine. Now create a file named azure-file-pvc.yaml and copy in the following YAML. 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. OpenStack the claim is paired with a volume that generally matches your request. 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. Using the --watch option causes the command to monitor the source path for any bound to a different PV. 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). Before starting, make sure that you're logged into your OpenShift cluster through the terminal and have created a project. I recently implemented a complete backup solution for our Red Hat OpenShift clusters. In You can find a summary of the key commands covered below. Finally, in part three, we'll cover copying files into a new persistent volume. On the NFS server, identify the location of the source volume as well as location used by a target volume, and use normal file system copy mechanisms. In this post, well cover manually copying files into and out of a container. AWS EBS, Charlotte Ellett. To see more information on each oc command, run it with the --help option. the directory does not exist, but rsync is used for copy, the directory is copy will fail. 31.1. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. volumeName and claimRef are specified. 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. Charlotte Ellett. In this post, you've learned about oc commands that you can use to transfer files to and from a running container. 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). We can use an Admission Webhook to prevent abuse of the privileged service account you create in user projects. oc rsync ./ dummy-1-9j3p3:/mnt --strategy=tar. Share persistent volume claims amongst containers in Kubernetes/OpenShift, Can't Share a Persistent Volume Claim for an EBS Volume between Apps. 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. A PersistentVolume object is a storage resource in an OpenShift Container Platform cluster. directory and its contents are copied to the destination. 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. oc rsync ./local/dir :/remote/dir --exclude=* --include= --no-perms: Copy the single file to the remote directory in the pod. 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. This process usually involves expanding volume objects in the CloudProvider, and then expanding the file system on the actual node. In this post, we'll cover manually copying files into and out of a container. selector-label OpenShift Do (odo) is a fast and easy . 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. 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 Sign up for the free trial of OpenShift Online. kubectl cp my-file my-pod:my-file -c my-container-name. This method skips the normal matching and binding process. Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. you could pick any pod as all will mount the same persistent volume. In addition to uploading files into a running container, you might also want to download files. are not in the local directory. You can request storage by creating PersistentVolumeClaim objects in your 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. this case, the administrator can specify the PVC in the PV using the claimRef As you saw above, in this case, the pod would be blog-1-9j3p3. is created locally and sent to the container where the tar utility is used to may be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH created for you. This is different than above, where we both claimed a new persistent volume and mounted it to the application at the same time. We're not going to be using the web console, but you can check the status of your project there if you wish. Otherwise, the Dot product of vector with camera's local positive x-axis? The --delete flag may be used to delete any files in the remote directory that This will cause a new deployment of our dummy application, this time with the persistent volume mounted. We're using the Apache HTTPD server purely as a means of keeping the pod running. will remain set to the same PVC name and namespace even if the PVC or the whole Use the appropriate commands to restore the database in the new database 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. Openshift Mymsql persistent storage won't mount on php, is docker storage driver a persistent storage. Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. 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). Edit /etc/origin/master/master-config.yaml and add the following: ValidatingAdmissionWebhook:configuration:apiVersion: v1disable: falsekind: DefaultAdmissionConfig. Otherwise, the In this case, since we're doing a one off copy, we can use the tar strategy instead of the rsync strategy. Can I use a vintage derailleur adapter claw on a modern derailleur. The source argument of the oc rsync command must point to either a local 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. PVC will be bound regardless of whether the PV satisfies the PVCs label In short, this solution makes it easy to: This post describes the PVC backup system I put together. 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. Become a Red Hat partner and get support in building customer solutions. example, rsync creates the destination directory if it does not exist and will The copy-files-to-volume Init container copies files that are in /opt/app-root in the S2I builder image onto the Persistent Volume. Note that the local directory that you want the file copied to must exist. In a production cluster, you would not use hostPath. guide provides instructions for cluster administrators on provisioning an name: Just as with standard rsync, if the directory name ends in a path separator (/), 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. Persistent Disk, Pending until the PV is Available. Undo working copy modifications of one file in Git? 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. In In this post, we're going to cover how to transfer files between your local machine and a running container. To upload the robots.txt file, we run: oc rsync . Even though NFS's root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs. Do you have an OpenShift Online account? Therefore, you can control the behavior via the same flags used In order to do this, you'll need to deploy a dummy application to mount the persistent volume against. to find the corresponding volume to mount. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. 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. In this post, you've learned about oc commands that you can use to copy files into a persistent volume. OpenShift Container Platform 3.3 Release Notes, Installing a Stand-alone Deployment of OpenShift Container Registry, Deploying a Registry on Existing Clusters, Configuring the HAProxy Router to Use the PROXY Protocol, Loading the Default Image Streams and Templates, Configuring Authentication and User Agent, Backing Docker Registry with GlusterFS Storage, Configuring Global Build Defaults and Overrides, Assigning Unique External IPs for Ingress Traffic, Restricting Application Capabilities Using Seccomp, Promoting Applications Across Environments. I am trying to copy some files to a persistent volume that will be later on mounted on a pod. RBD, selector, access modes, and resource requests. example, oc rsync creates the destination directory if it does not exist and Persistent Volume Claim Object Definition, Example 1. Part two will be about live synchronization. For more information on access modes, see the Kubernetes persistent volume documentation. The destination argument of the oc rsync command must point to a directory. volumeName field. migration guide to find the exact commands for each of our supported database An example download command is: ``` $ docker pull openshift/jenkins-2-centos7 ``` Check the contents of the current directory by running: You should see that the local machine now has a copy of the file. 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. 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. namespace no longer exists. Connect and share knowledge within a single location that is structured and easy to search. If you followed the previous steps, you can mount the share you created earlier by using the following command to create a . example : 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. hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, You can use the CLI to copy local files to or from a remote directory in a container. Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. move to the folder from which you want to copy the file. Get your applications running in minutes with no installation needed. 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). 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). 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. developer (OpenShift user) can claim space from a persistent volume specific to a project PVCs are requests for PVs and also act as claim checks to the resources claiming more storage than the PV provides, results in failure VMDK Since we are dealing with virtual disk, VMware provides several disk types: PVC from binding to the specified PV before yours does. A hostPath PersistentVolume uses a file or directory on the Node to emulate network-attached storage. rapidly changing file system does not result in continuous synchronization 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. kubectl cp my-file my-pod:my-file. to oc rsync. 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. 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: Chapter 31. On the worker nodes, let's add an extra disk. All you need to do is supply the path where the persistent volume is mounted in the container as the target directory. 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. sent 30 bytes received 40027 bytes 26704.67 bytes/sec total size is 39936 speedup is 1.00. remote shell program to enable it to connect to the remote pod, and are an 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. The PV will only be able to bind to a PVC that has the same name and At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. OpenShift Container Platform finds the kubectl cp /path/to/file my-pod:/path/to/file. Can non-Muslims ride the Haramain high-speed train in Saudi Arabia? uploads. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Red Hat Training. When complete, you can validate that the files were transferred by listing the contents of the target directory inside of the container. 40 -rw-rw-r-- 1 1000040000 root 39936 Jun 6 05:53 db.sqlite3. Persistent Volumes (PV) allows to share the file storage between application pods and external world. kubectl cp my-dir my-pod:my-dir. Create a file named blob-nfs-pvc.yaml and copy in the following YAML. A PersistentVolumeClaim is a 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 Unlike when copying from the container to the local machine, there's no form for copying a single file. A PersistentVolume object is a storage resource in an OpenShift Container Platform cluster. 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. 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. 29.3. label selector is ignored. 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. 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. One example of where this might be done is during development when a dynamic scripting language is being used. NFS, 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. 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. The oc rsync command uses the local rsync command if present on the clients 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. your claim so that nobody elses claim can bind to it before yours does. 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. 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. Replace mysql|MYSQL with pgsql|PGSQL or 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/. 1 - Create an Azure Red Hat OpenShift cluster 2 - Connect to an Azure Red Hat OpenShift cluster 3 - Delete an Azure Red Hat OpenShift cluster Quickstarts How-to guides Cluster operations Networking Storage Encrypt cluster data with customer-managed key Create an Azure Files Storageclass Use the built-in container registry 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. file system changes, and synchronizes changes when they occur. Is lock-free synchronization always superior to synchronization using locks? 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. The result will be a running container. If there are additional files in the target directory which don't exist in the container, those files will be left as is. 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 long-term solution for limiting who can claim a volume is in Other solutions need to install custom components (often a centralized control plane server and their own CLI tool). We wanted to avoid this if possible, ideally using open-source software. Therefore, you can control the behavior via the same flags used Your data sits there. oc set volume dc/dummy --add --name=tmp-mount --claim-name= --type pvc --claim-size=1G --mount-path /mnt: Claim a persistent volume and mount it against the dummy application pod at the directory /mnt so that files can be copied into the persistent volume using oc rsync. set the volumeName and/or claimRef yourself will have no such annotation, Owner 65534 is not required for NFS exports. A complete example of this can be found in the OpenShift documentation. Do you have an OpenShift Online account? Use "kubectl cp" to Copy Files to and from Kubernetes Pods. Second, you can access it from the pod that uses the PersistentVolumeClaim. created for you. This is part three of a three-part series. oc set volume dc/dummy --add --name=tmp-mount --claim-name=data --mount-path /mnt. Support for copying local files to or from a container is built into Part one covered manually copying files into and out of a container. To copy files from the local machine to the container, we'll again use the oc rsync command. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. blog-1-9j3p3:/opt/app-root/src/htdocs --exclude=* --include=robots.txt --no-perms. This post is based on one of OpenShifts interactive learning scenarios. Therefore, to avoid these scenarios and rapidly changing file system does not result in continuous synchronization By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. That is, although you can make changes to the local container file system of a running image, the changes are not permanent. Specifying a volumeName in your PVC does not prevent a different 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. This requires that the remote container also have the rsync command. binds them together. volume binding before resorting to setting claimRefs on behalf of users. 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. manually invoking oc rsync repeatedly, including any arguments normally passed If tar is not available in the remote container, then the | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . To try it and our other tutorials without needing to install OpenShift, visit https://learn.openshift.com. The tar copy method does not provide the same functionality as rsync. You can see this procedure in the code. You can use the CLI to copy local files to or from a remote directory in a container. 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. In the case that you want to use a standard rsync command line option that is This means that, although the files can be added to the directory, permissions on existing directories cannot be changed. $ 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. environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its Storage is provisioned by your cluster administrator by creating 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. machine and the remote container. calls. the ensure
