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. 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. Attach this archive PV to the new database server pod and restore from your chosen the dumpfile. kubectl cp my-pod:my-file my-file. Copying Files to or from a Container. Replace mysql|MYSQL with pgsql|PGSQL or If tar is not available in the remote container, then the Migrate between different storage types (NFS/NAS to iSCSI/SAN, for example). 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. Ceph 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. An example download command is: ``` $ docker pull openshift/jenkins-2-centos7 ``` Here we find, for example, databases with their own tools and procedures to create application-consistent backups. In this post, you've learned about oc commands that you can use to copy files into a persistent volume.
