In addition to uploading files into a running container, you might also want to download files. Our Validating Webhook denysabck intercepts requests to the API and discards any request that uses the Service Account pvc-backup-deployer for any container image other than our BackupEr image. 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. When specifying a pod directory the directory name must be prefixed with the pod 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: We will discuss the security implications of this UID munging later in this post. development. $ 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. oc set volume dc/dummy --add --name=tmp-mount --claim-name= --mount-path /mnt: Mount an existing persistent volume against a dummy application pod at the directory /mnt so that files can be copied into the persistent volume using oc rsync. Part one covered manually copying files into and out of a container. BackupEr also has its own PVC. Here we find, for example, databases with their own tools and procedures to create application-consistent backups. blog-1-9j3p3:/opt/app-root/src/htdocs --exclude=* --include=robots.txt --no-perms. Otherwise, the not available in oc rsync, for example the --exclude-from=FILE option, it There's no reason to wait. When specifying a pod directory the directory name must be prefixed with the pod Security: As a basic means of reducing the exposed surface, we avoided anything that relied on Kubernetes NodePorts or privileged pods.

Before starting, make sure that you're logged into your OpenShift cluster through the terminal and have created a project. In file system changes, and synchronizes changes when they occur. oc rsync :/remote/dir ./local/dir: Copy the directory from the pod to the local directory. might be possible to use standard rsync 's --rsh (-e) option or RSYNC_RSH The --delete flag may be used to delete any files in the remote directory that and oc rsync ./ dummy-1-9j3p3:/mnt --strategy=tar. 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). The existing options I checked didnt fit my needs for a variety of reasons: For this reason I decided to implement a homemade solution. 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 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. 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. hbspt.cta._relativeUrls=true;hbspt.cta.load(4305976, '1ba92822-e866-48f0-8a92-ade9f0c3b6ca', {"useNewLoader":"true","region":"na1"}); OpenShift Commons, 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.

To create a dummy application for this purpose, run this command: oc run dummy --image centos/httpd-24-centos7. When BackupEr starts, it runs the backup.sh script to copy the data from MyPods source PVC to its own target PVC. 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. 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 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. | oc rsh nginx-12-6lfbo tar xofC - /usr/share/nginx/html .

OpenShift Container Platform clusters can be provisioned with persistent storage using GlusterFS. images. OpenShift Container Platform finds the volume backing the claim and mounts it into the pod. oc rsync :/remote/dir/. 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. We're using the Apache HTTPD server purely as a means of keeping the pod running. The PVCs access modes and resource requests mongodb|MONGODB and refer to You'll be using just the oc command line tool. volume binding before resorting to setting claimRefs on behalf of users. After step 3 binds the new SCC to the backup Service Account, , you can restore data when you want. If there are additional files in the target directory which don't exist in the container, those files will be left as is. The PVs and PVCs where you the directory does not exist, but rsync is used for copy, the directory is This post is based on one of OpenShifts interactive learning scenarios. NOTE: The communication between your cluster/API and your Webhook must be secured and with trusteable SSL certificates. 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. kubectl cp <file-spec-src> <file-spec-dest>.

Do you have an OpenShift Online account? If tar is not available in the remote container, the If you didn't want to copy it into the current directory, ensure that the target directory has been created beforehand. 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. RBD, File Storage. If, instead of copying a single file, you want to copy a complete directory, leave off the --include and --exclude options. Now create a file named azure-file-pvc.yaml and copy in the following YAML. Is lock-free synchronization always superior to synchronization using locks? 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. 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. This will cause a new deployment of our dummy application, this time with the persistent volume mounted. environment variable as a workaround, as follows: Both of the above examples configure standard rsync to use oc rsh as its Pending until the PV is Available. 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. Permissions on directories and files should be set as part of the process of building the image. uploads. 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.). Some files, such as a databases backing store, may be written to in an almost constant stream. I didnt mention this before, but I tried to keep it the installation steps as simple as possible, as this is a very interesting approach (GA since 3.11 and above). Individual files are not supported. Therefore, to avoid these scenarios and In this post, you've learned about oc commands that you can use to copy files into a persistent volume. You can provision volumes either statically or dynamically for file-based storage. bound to a different PV. Expanding PVCs based on volume types that need file system resizing (such as GCE PD, EBS, and Cinder) is a two-step process. The data is saved in files and folders, and presented to both the system storing it and the system retrieving it in the same format. This is a useful tool for copying database archives to and from your pods for backup and restore purposes. Owner 65534 is not required for NFS exports. This method skips the normal matching and binding process. Expanding Persistent Volume Claims with a File System. All you need to do is supply the path where the persistent volume is mounted in the container as the target directory. We can now copy some files into the persistent volume using the command: tar cf - . Connect and share knowledge within a single location that is structured and easy to search. Even though NFS's root_squash maps root (UID 0) to nfsnobody (UID 65534), NFS exports can have arbitrary owner IDs.
