基于 rbd nbd 的支持抢锁的 rbd docker volume plugin

1.注意

本plugin和jewel(10.2.2)一起测试过，需要apply 下面的patch:

ceph-patch/rbd-nbd-ceph-10.2.2.patch

2. 编译rpm包

$ git clone https://github.com/yanghonggang/rbd-docker-plugin-nbd.git rbd-docker-plugin$ cd rbd-docker-plugin$ make rpms...$ls rpmbuild/RPMS/x86_64/rbd-docker-plugin-1.5.2-1.el7.centos.x86_64.rpm  rbd-docker-plugin-debuginfo-1.5.2-1.el7.centos.x86_64.rpm

3. 安装使用

rpm -ivh *.rpmsystemctl enablesystemctl start rbd-docker-plugin

需要重新启动使用了rbd卷的container 或者重启docker daemon

4. docker container 创建参数说明

# docker run --name disk22 --volume-driver rbd -v mpool/disk2@1000:/root/hehe -it anna /bin/bash--volume-driver rbd // 表示要使用 rbd-docker-plugin作为volume的后端-v 中 mpool 为用于创建 image 的 ceph pool     disk2为image的名字     1000为1000MB/root/hehe 为container内部的映射目录

5.所有可配置条目
