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. If you want to learn more or refresh your knowledge about persistent storage, check out the Persistent Storage topic in the OpenShift documentation. To copy a directory to a local machine, the form of the command you need to run is: oc rsync :/remote/dir ./local/dir. In this post, well cover manually copying files into and out of a container. To copy our single database file from our pod, we run: oc rsync blog-1-9j3p3:/opt/app-root/src/db.sqlite3 . Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. ensure your claim gets bound to the volume you want, you must ensure that both 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. 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. environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its This is part three of a three-part series. Storage can be made available to you by laying claims to the resource. kubectl cp pod-1:my-file pod-2:my-file. Edit /etc/origin/master/master-config.yaml and add the following: ValidatingAdmissionWebhook:configuration:apiVersion: v1disable: falsekind: DefaultAdmissionConfig. There are at least 2 steps involved in scheduling your first container on a Openshift cluster. Chapter 31. Otherwise, the volumeName. extract the files. Set the spec.nodeName of the BackupEr pod to the desired OCP node. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. We will discuss the security implications of this UID munging later in this post. Backup that PV with our custom solution. are not in the local directory. Traditionally, backup and restore operations involve two different layers. 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: blog-1-9j3p3:/opt/app-root/src/htdocs --exclude=* --include=robots.txt --no-perms. Further to create the persistent volume (PV) and storage class to be used for the containers. 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. To learn more, see our tips on writing great answers. alternative to running oc rsync. What other topics would you like to see in the future on this blog? 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. 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 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. label selector is ignored. 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. The example assumes an existing database container. 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. kubectl cp /path/to/file my-pod:/path/to/file. kubectl cp my-file my-pod:my-file. For more information on access modes, see the Kubernetes persistent volume documentation. Note: If the target directory contains existing files with the same name as a file in the container, the local file will be overwritten. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. pv.kubernetes.io/bound-by-controller annotation. Get your applications running in minutes with no installation needed. argument, the command runs forever. 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. claim with the given name in the same namespace as the pod, then uses the claim What other topics would you like to see in the future on this blog? 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. 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. October 10, 2017 | by oc rsync :/remote/dir ./local/dir --delete: Copy the contents of the directory from the pod to the local directory. kubectl cp my-dir my-pod:my-dir. projects: A PersistentVolume is a specific resource. remote shell program to enable it to connect to the remote pod, and are an Cinder, volumeName field. October 5, 2017 | by oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. Channel. | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html . Second, you can access it from the pod that uses the PersistentVolumeClaim. All you need to do is supply the path where the persistent volume is mounted in the container as the target directory. Demo: Persistent volume storage in a MySQL database. How can I think of counterexamples of abstract mathematical objects? If tar is not available in the remote container, then the copy will fail. Clone your PVC as many times as you want. 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. For an inside deployment I'd recommend you use a Service instead of a Route (the service must be secured with trusteable certs too). Your data sits there. make a request for storage resources using a PersistentVolumeClaim object; The oc rsync command exposes fewer command line options than standard rsync. matching and binding process by inspecting a Bound PV and PVC pair for the For The tar copy method does not provide the same functionality as oc rsync. You'll be using just the oc command line tool. That pattern is then overridden for just the robots.txt file by using the --include=robots.txt file, ensuring that robots.txt is copied. 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. 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. If your application doesnt automatically detect new or changed files, you may need to notify it in some way to pick up the changes. Unlike when copying from the container to the local machine, there's no form for copying a single file. OpenShift Container Platform finds the hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, NOTE: The communication between your cluster/API and your Webhook must be secured and with trusteable SSL certificates. $ 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. The only constraint here is to deploy the BackupEr pod on the same OpenShift cluster node with the pod/PVC you want to back up. 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. OpenShift Container Platform finds the volume backing the claim and mounts it into the pod. 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. 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 can find a summary of the key commands covered below. You can use the CLI to copy local files to or from a remote directory in a container. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. 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. When using the --watch option, the behavior is effectively the same as the claim is paired with a volume that generally matches your request. File storage, also called file-level or file-based storage, stores data in a hierarchical structure.
