利用docker快速搭建ceph radosgw环境

安装docker

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3: 更新并安装 Docker-CE

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.

docker run -d --name demo -e MON_IP=$IP -e CEPH_PUBLIC_NETWORK=$NETWORK --net=host -v /var/lib/ceph:/var/lib/ceph -v /etc/ceph:/etc/ceph ceph/demo demo
