Example 4 with Container

use of io.fabric8.kubernetes.api.model.Container in project che by eclipse.

the class OpenShiftConnector method commit.

/**
     * OpenShift does not support taking image snapshots since the underlying assumption
     * is that Pods are largely immutable (and so any snapshot would be identical to the image
     * used to create the pod). Che uses docker commit to create machine snapshots, which are
     * used to restore workspaces. To emulate this functionality in OpenShift, commit
     * actually creates a new ImageStreamTag by calling {@link OpenShiftConnector#tag(TagParams)}
     * named for the snapshot that would be created.
     *
     * @see DockerConnector#commit(CommitParams)
     */
@Override
public String commit(final CommitParams params) throws IOException {
    // e.g. machine_snapshot_mdkfmksdfm
    String repo = params.getRepository();
    // container ID
