docker-单机启动ceph集群（macOS）

pull镜像

前提先安装好docker
本次实验环境为：操作系统macos docker版本

docker pull ceph/osd
docker pull ceph/mon

1.创建Ceph专用网络

sudo docker network create --driver bridge --subnet 172.20.0.0/16 ceph-network

2.创建相关文件及更改文件权限

sudo mkdir -p /etc/ceph /var/lib/ceph/ /var/log/ceph/

sudo chmod -R 777 /etc/ceph /var/lib/ceph/ /var/log/ceph/

3.启动mon节点

docker run -itd --name mymon --network ceph-network --ip 172.20.0.10 -e MON_NAME=mymon -e MON_IP=172.20.0.10 -v /etc/ceph:/etc/ceph ceph/mon

添加配置vim /etc/ceph/ceph.conf
在文件末尾添加：

osd journal size = 100
osd pool default pg num = 8
osd pool default pgp num = 8
osd pool default size = 2
osd pool default min size =1
osd max object name len = 256
osd max object namespace len = 64
public network = 172.20.0.0/24
cluster network = 172.20.0.0/24

4.启动osd

docker exec mymon ceph osd create

docker run -itd --name osd0 --network ceph-network -e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=mymon -e MON_IP=172.20.0.10 -v /etc/ceph:/etc/ceph -v /var/lib/ceph/osd/0:/var/lib/ceph/osd/ceph-0 ceph/osd

如果出现这个问题：

查看集群状态

docker exec -it mymon ceph -s

再起两个osd

docker exec mymon ceph osd create

docker run -itd --name osd1 --network ceph-network -e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=mymon -e MON_IP=172.20.0.10 -v /etc/ceph:/etc/ceph -v /var/lib/ceph/osd/1:/var/lib/ceph/osd/ceph-1 ceph/osd

docker exec mymon ceph osd create

docker run -itd --name osd2 --network ceph-network -e CLUSTER=ceph -e WEIGHT=1.0 -e MON_NAME=mymon -e MON_IP=172.20.0.10 -v /etc/ceph:/etc/ceph -v /var/lib/ceph/osd/2:/var/lib/ceph/osd/ceph-2 ceph/osd

查看集群状态：

docker exec -it mymon ceph -s

再起两个mon

docker run -itd --name mymon_1 --network ceph-network --ip 172.20.0.11 -e MON_NAME=mymon_1 -e MON_IP=172.20.0.11 -v /etc/ceph:/etc/ceph ceph/mon
 
docker run -itd --name mymon_2 --network ceph-network --ip 172.20.0.12 -e MON_NAME=mymon_2 -e MON_IP=172.20.0.12 -v /etc/ceph:/etc/ceph ceph/mon

集群状态：
docker exec -it mymon ceph -s

创建网关节点：

docker run -itd --name myrgw --network ceph-network --ip 172.20.0.5 -p 9080:80 -e RGW_NAME=myrgw -v /etc/ceph:/etc/ceph ceph/radosgw

集群状态：

docker exec -it mymon ceph -s

docker exec mymon ceph osd tree

测试添加rgw用户

sudo docker exec myrgw radosgw-admin user create --uid="test" --display-name="test user"

打印输出：

查看docker的节点：

docker ps
