andrewberry/ceph-docker repository overview

⁠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)
