This means that, although the files can be added to the directory, permissions on existing directories cannot be changed. 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. How can I think of counterexamples of abstract mathematical objects? Individual files are not currently supported. are not in the local directory. according to the normal binding process. mongodb|MONGODB and refer to kubectl cp my-dir my-pod:my-dir. Persistent Volumes (PV) allows to share the file storage between application pods and external world. kubectl cp /path/to/file my-pod:/path/to/file. Enable use of Minishift as staging setup for a proper OpenShift setup i.e. kubectl cp my-file my-pod:my-file -c my-container-name. blog-1-9j3p3:/opt/app-root/src/htdocs --exclude=* --include=robots.txt --no-perms. you could pick any pod as all will mount the same persistent volume. will be created locally and sent to the container where tar will be used to The source argument of the oc rsync command must point to either a local | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . In the upcoming OpenShift 4.8 release, our teamwill deliver complete provider networks support when deploying on Red Hat OpenStack. The --delete flag may be used to delete any files in the remote directory that oc rsync :/remote/dir/. In a production cluster, you would not use hostPath. Finally, in part three, well cover copying files into a new persistent volume. 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. Truce of the burning tree -- how realistic? The copy-files-to-volume Init container copies files that are in /opt/app-root in the S2I builder image onto the Persistent Volume. manually invoking oc rsync repeatedly, including any arguments normally passed Persistent Disk, When specifying a pod directory the directory name must be prefixed with the pod will remain set to the same PVC name and namespace even if the PVC or the whole Transferring Files In and Out of Containers in OpenShift, Part 1: Manually Copying Files, Using QoS DSCP in OpenShift Container Platform, Deploying CockroachDB on one Red Hat OpenShift cluster, Deploy OpenShift on OpenStack Provider Networks. One example of where this might be done is during development when a dynamic scripting language is being used. Share Note: If the target directory contains existing files with the same name as a file in the container, the local file will be overwritten. images. Not the answer you're looking for? Backup that PV with our custom solution. The destination argument of the oc rsync command must point to a directory. Pending until the PV is Available. Try, Buy, Sell Red Hat Hybrid Cloud This is part one of a three-part series. Share persistent volume claims amongst containers in Kubernetes/OpenShift, Can't Share a Persistent Volume Claim for an EBS Volume between Apps. secretPath is the path to the secret defined in Vault. 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. 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. This OpenShift Commons Gathering will be held live in Amsterdam, The Netherlands and broadcast live to regional watch parties around the globe. Persistent Volume Claim Object Definition, Example 1. alternative to running oc rsync. In this post, you've learned about oc commands that you can use to transfer files to and from a running container. Create Filesystem in RHCOS. 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. In order to do this, you'll need to deploy a dummy application to mount the persistent volume against. For In the case that you wish to use a standard rsync command line option which is Duress at instant speed in response to Counterspell. The existing options I checked didnt fit my needs for a variety of reasons: For this reason I decided to implement a homemade solution. 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. Therefore, you can control the behavior via the same flags used Are you ready for Amsterdam? 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. 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. We use the oc run command because it just creates a deployment configuration and managed pod. 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. Connect and share knowledge within a single location that is structured and easy to search. At the moment, these features are not implemented directly in Kubernetes, and it doesn't come out-of-the-box with any Kubernetes distribution. 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. When using the --watch option, the behavior is effectively the same as Unlike when copying from the container to the local machine, there's no form for copying a single file. Create the vault-database SecretProviderClass. The extent of . move to the folder from which you want to copy the file. pv.kubernetes.io/bound-by-controller annotation. container from the copied database archive directory: You now have two MySQL database pods running in your project with the archived CentOS7 based image The v3.x images are available on DockerHub. rapidly changing file system does not result in continuous synchronization Cinder, the directory does not exist, but rsync is used for copy, the directory is Persistent Volume Claim Object Definition with volumeName, Persistent Volume Object Definition with claimRef, OpenShift Container Platform 3.11 Release Notes, Installing a stand-alone deployment of OpenShift container image registry, Deploying a Registry on Existing Clusters, Configuring the HAProxy Router to Use the PROXY Protocol, Accessing and Configuring the Red Hat Registry, Loading the Default Image Streams and Templates, Configuring Authentication and User Agent, Using VMware vSphere volumes for persistent storage, Dynamic Provisioning and Creating Storage Classes, Enabling Controller-managed Attachment and Detachment, Complete Example Using GlusterFS for Dynamic Provisioning, Switching an Integrated OpenShift Container Registry to GlusterFS, Using StorageClasses for Dynamic Provisioning, Using StorageClasses for Existing Legacy Storage, Configuring Azure Blob Storage for Integrated Container Image Registry, Configuring Global Build Defaults and Overrides, Deploying External Persistent Volume Provisioners, Installing the Operator Framework (Technology Preview), Advanced Scheduling and Pod Affinity/Anti-affinity, Advanced Scheduling and Taints and Tolerations, Extending the Kubernetes API with Custom Resources, Assigning Unique External IPs for Ingress Traffic, Restricting Application Capabilities Using Seccomp, Encrypting traffic between nodes with IPsec, Configuring the cluster auto-scaler in AWS, Promoting Applications Across Environments, Creating an object from a custom resource definition, MutatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], ValidatingWebhookConfiguration [admissionregistration.k8s.io/v1beta1], LocalSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectAccessReview [authorization.k8s.io/v1], SelfSubjectRulesReview [authorization.k8s.io/v1], SubjectAccessReview [authorization.k8s.io/v1], ClusterRoleBinding [authorization.openshift.io/v1], ClusterRole [authorization.openshift.io/v1], LocalResourceAccessReview [authorization.openshift.io/v1], LocalSubjectAccessReview [authorization.openshift.io/v1], ResourceAccessReview [authorization.openshift.io/v1], RoleBindingRestriction [authorization.openshift.io/v1], RoleBinding [authorization.openshift.io/v1], SelfSubjectRulesReview [authorization.openshift.io/v1], SubjectAccessReview [authorization.openshift.io/v1], SubjectRulesReview [authorization.openshift.io/v1], CertificateSigningRequest [certificates.k8s.io/v1beta1], ImageStreamImport [image.openshift.io/v1], ImageStreamMapping [image.openshift.io/v1], EgressNetworkPolicy [network.openshift.io/v1], OAuthAuthorizeToken [oauth.openshift.io/v1], OAuthClientAuthorization [oauth.openshift.io/v1], AppliedClusterResourceQuota [quota.openshift.io/v1], ClusterResourceQuota [quota.openshift.io/v1], ClusterRoleBinding [rbac.authorization.k8s.io/v1], ClusterRole [rbac.authorization.k8s.io/v1], RoleBinding [rbac.authorization.k8s.io/v1], PriorityClass [scheduling.k8s.io/v1beta1], PodSecurityPolicyReview [security.openshift.io/v1], PodSecurityPolicySelfSubjectReview [security.openshift.io/v1], PodSecurityPolicySubjectReview [security.openshift.io/v1], RangeAllocation [security.openshift.io/v1], SecurityContextConstraints [security.openshift.io/v1], VolumeAttachment [storage.k8s.io/v1beta1], BrokerTemplateInstance [template.openshift.io/v1], TemplateInstance [template.openshift.io/v1], UserIdentityMapping [user.openshift.io/v1], Container-native Virtualization Installation, Container-native Virtualization Users Guide, Container-native Virtualization Release Notes. 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). extract the files. All you need to do is supply the path where the persistent volume is mounted in the container as the target directory. machine. Part two went into live synchronization. to find the corresponding volume to mount. sent 30 bytes received 40027 bytes 26704.67 bytes/sec total size is 39936 speedup is 1.00. 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. remote shell program to enable it to connect to the remote pod, and are an Comment and let us know! This will cause a new deployment of our dummy application, this time with the persistent volume mounted. Copying Files to or from a Container. calls. to oc rsync. There you are: A tool to backup, migrate, or clone your PVs inside an OpenShift Kubernetes cluster! 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. directory and its contents are copied to the destination. Other solutions need to install custom components (often a centralized control plane server and their own CLI tool). cases. Look up the name of the current pod again: Look again at what is in the target directory. This 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. 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. 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. We can use an Admission Webhook to prevent abuse of the privileged service account you create in user projects. argument, the command runs forever. A long-term solution for limiting who can claim a volume is in When using the --watch option, the behavior is effectively the same as By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Dot product of vector with camera's local positive x-axis? created for you. Individual files are not supported. The other layer is the underlying storage. File storage, also called file-level or file-based storage, stores data in a hierarchical structure. This allows the claim to be used as a volume in a pod. Do you have an OpenShift Online account? We can now copy some files into the persistent volume using the command: tar cf - . 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. The core component is a pod based on a custom container image. File Storage. In this post, you've learned about oc commands that you can use to copy files into a persistent volume. directory or a pod directory. Part two will be about live synchronization. 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. Comment and let us know! Would the reflected sun's radiation melt ice in LEO? You can A complete example of this can be found in the OpenShift documentation. machine and the remote container. Part one covered manually copying files into and out of a container. Let's look at how this database file can be copied back to the local machine. 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. only the contents of the directory are copied to the destination. between the two is a process that matches a claim to an available volume and 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 Synchronization occurs after short quiet periods to ensure a 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. and You can use a mix of your databases backup tooling with the solution described in this article to get complete backups of database snapshots as part of the backup of Persistent Volumes. You can use the CLI to copy local files to or from a remote directory in a container. OpenShift Do (odo) is a fast and easy .

You may also want your cluster administrator to "reserve" the volume for only With this Specifying a volumeName in your PVC does not prevent a different rapidly changing file system does not result in continuous synchronization volumeName field. . Ceph 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. Overview. The command for copying files from the local machine to the container needs to be of the form: oc rsync ./local/dir :/remote/dir. 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. selector, access modes, and resource requests. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. PersistentVolume objects from sources such as GCE Persistent Disk, AWS 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. 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. 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 Jose Antonio Gonzalez Prada. The PVC is free to choose another PV to bind to Traditionally, backup and restore operations involve two different layers. Therefore, to avoid these scenarios and must still be satisfied in order for the PV and PVC to be bound, though the 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. 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. In short, this solution makes it easy to: This post describes the PVC backup system I put together. name: Just as with standard rsync, if the directory name ends in a path separator (/), If secretKey is a key name within that secret. 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. 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. selector-label When a PV has its claimRef set to some PVC name and namespace, and is Synchronization occurs after short quiet periods to ensure a Create a file named blob-nfs-pvc.yaml and copy in the following YAML. 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. For more information on access modes, see the Kubernetes persistent volume documentation. 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. To try it and our other tutorials without needing to install OpenShift, visit https://learn.openshift.com. 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. 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. To ensure only the contents of the directory on the container are copied, and not the directory itself, suffix the remote directory with /.. GlusterFS, After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. This is because the persistent volume is no longer mounted, and you're looking at the directory within the local container file system. Note that this solution addresses only backing up and migrating user volumes, not Kubernetes control plane data and configuration, such as etcd. 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. For an inside deployment I'd recommend you use a Service instead of a Route (the service must be secured with trusteable certs too). Launching the CI/CD and R Collectives and community editing features for Standard concise way to copy a file in Java? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Chapter 31. The main application container utilizes these files at runtime for execution. Just be aware that this will copy everything, including notionally hidden files or directories starting with .. 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. Deploy container and mount volume - CLI. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. If 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). uploads. Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. The first is the application layer. In the case that you want to use a standard rsync command line option that is the claim is paired with a volume that generally matches your request. Some files, such as a databases backing store, may be written to in an almost constant stream. 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. remote shell program to enable it to connect to the remote pod, and are an oc rsync ./local/dir :/remote/dir --strategy=tar: Copy the directory to the remote directory in the pod. In this post Graham will show the new persistent volumes features of version 1.1.3 of the All-in-One OpenShift virtual machine. Finally, in part three, we'll cover copying files into a new persistent volume. 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 two will be about live synchronization. Do you have an OpenShift Online account? 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. With this 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. 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.
