Staging a Docker image file on ZooKeeper ensemble nodes

Before performing this procedure, verify that approximately 170MB of temporary space is available on the file system where /root is located.
Use this procedure to add a Docker image file to the Control Center delegate hosts that are ZooKeeper ensemble nodes. Delegate hosts that are not ZooKeeper ensemble nodes do not need the file.
  1. Log in to a delegate host as root, or as a user with superuser privileges.
  2. Copy or move the file to /root.
  3. Add execute permission to the file.
    chmod +x /root/*.run
