Demo container

This Dockerfile may be used to bootstrap a Ceph cluster with all the Ceph daemons running.

*/!\ THIS CONTAINER IS NOT RECOMMENDED FOR PRODUCTION USAGE /!*

The main purpose of this container is to quickly get a Ceph cluster up and running by reducing all the setup steps. The container provides all the Ceph daemons, so you can rapidly start playing with Ceph.

Usage

The environment variables MON_NAME and MON_IP are required:

  • MON_NAME is the name of the monitor (DEFAULT: hostname)
  • MON_IP is the IP address of the monitor (public)
  • RGW_NAME is the name of rados gateway instance (DEFAULT: hostname)
  • RGW_CIVETWEB_PORT is the port of the rados gateway (DEFAULT: 80)
  • CLUSTER is the name of the cluster (DEFAULT: ceph)
  • CEPH_PUBLIC_NETWORK is the network where the OSD should communicate
  • CEPH_DEMO_UID, CEPH_DEMO_ACCESS_KEY, CEPH_DEMO_SECRET_KEY, and CEPH_DEMO_BUCKET can be used to auto-provision an account.

Commonly, you will want to bind-mount your host's /etc/ceph into the container. For example:

docker run -d --net=host -v /etc/ceph:/etc/ceph -e MON_IP=192.168.0.20 -e CEPH_PUBLIC_NETWORK=192.168.0.0/24 ceph/demo

Tip

If you get user_xattr error, try to remount your docker partition:

sudo mount -o remount,user_xattr,rw $(df -P /var/lib/docker |tail -1 |tr -s ' ' |cut -d' ' -f6)
