Pulling the ZooKeeper image for Docker

To perform this procedure, ZooKeeper ensemble nodes must have internet access.
Use this procedure to pull the Docker image for the ZooKeeper service from Docker Hub to a ZooKeeper ensemble node. Repeat this procedure on each node in the ZooKeeper ensemble.
  1. Log in to the ZooKeeper ensemble node as root, or as a user with superuser privileges.
  2. Identify the images associated with the installed version of serviced.
    serviced version | grep Images
    Example result:
    IsvcsImages: [zenoss/serviced-isvcs:v54 zenoss/isvcs-zookeeper:v8]

    In this example, the tag of the ZooKeeper image is isvcs-zookeeper:v8.

  3. Pull the required image from Docker Hub to the local repository.
    Replace ZooKeeper-Tag with the tag displayed in the previous step:
    docker pull zenoss/ZooKeeper-Tag
