使用docker 部署 ceph

ertwer

获取ceph image

1 2	docker pull  ceph/mon:hammer docker pull  ceph/osd:hammer

准备硬盘

1 2 3

mkfs.xfs /dev/sdd1 mkdir -p /opt/osd/0 mount -o defaults,noatime,nodiratime,noexec,nodev  /dev/sdd1  /opt/osd/0/

部署mon

1 2 3 4 5 6 7

docker run -d \        --name mon0 \        -e MON_IP=10.64.0.4 \        -e MON_NAME=mon0 \        --net=host \        -v /etc/ceph:/etc/ceph \        ceph/mon:hammer

编辑ceph.conf

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[global]     fsid = 4ae8b795-a8b2-4904-9573-f6f658838db3     public network = 10.64.0.0/26     cluster network = 10.64.0.0/26     auth cluster required = cephx     auth service required = cephx     auth client required = cephx     osd pool default size = 3     osd pool default min size = 2     osd crush update on start  = false [mon]     mon initial members = mon0     mon host = 10.64.0.4 [mon.mon0]     host = mon0     mon addr = 10.64.0.4:6789 docker restart mon0

部署osd

1 2 3 4 5 6 7 8 9

docker exec mon0 ceph osd create docker run -d \        --name=osd0 \        --net=host \        -e CLUSTER=ceph \        -e WEIGHT=1.0 \        -v /etc/ceph:/etc/ceph \        -v /opt/osd/0:/var/lib/ceph/osd/ceph-0 \        ceph/osd:hammer

复制/etc/ceph到其余节点，在其余节点上部署osd

1 2 3 4 5 6 7 8 9 10 11 12 13

scp -r /etc/ceph root@10.64.0.53:/etc/ docker exec mon0 ceph osd create mkfs.xfs /dev/sda1 mkdir -p /opt/osd/1 mount -o defaults,noatime,nodiratime,noexec,nodev  /dev/sda1  /opt/osd/1/ docker run -d \        --name=osd1 \        --net=host \        -e CLUSTER=ceph \        -e WEIGHT=1.0 \        -v /etc/ceph:/etc/ceph \        -v /opt/osd/1:/var/lib/ceph/osd/ceph-1 \        ceph/osd:hammer
