使用Ansible的Docker NFS卷

如何解决使用Ansible的Docker NFS卷

给出一个简单的示例，例如

$ docker volume create --driver local \
    --opt type=nfs \
    --opt o=addr=192.168.1.1,rw \
    --opt device=:/path/to/dir \
    foo

如何使用Ansible做同样的事情？我尝试过

- name: NFS volume mount
  docker_volume:
    driver: "local"
    driver_options:
      type: nfs
      o: "addr=192.168.1.1,rw"
      device: /path/to/dir
    volume_name: foo

这将创建没有错误的卷，但是当该卷与docker_container模块一起使用时，它将失败。

TASK [oracle-database : docker_container] **************************************
fatal: [oracle]: FAILED! => {"changed": false,"msg": "Error starting container 1beb3254e25a8fe47cd78e803a2050f24020cf72e138472d7d14d963e02bec7f: 500 Server Error: Internal Server Error (\"{\"message\":\"error while mounting volume '/var/lib/docker/volumes/foo/_data': failed to mount local volume: mount /path/to/dir:/var/lib/docker/volumes/foo/_data,data: addr=192.168.1.1: invalid argument\"}\")"}

当我使用Ansibe创建卷时

[root@oracle ~]# docker volume inspect oracle-dumps
[
    {
        "CreatedAt": "2020-08-31T02:07:14-07:00","Driver": "local","Labels": null,"Mountpoint": "/var/lib/docker/volumes/foo/_data","Name": "foo","Options": {
            "device": "/path/to/dir","o": "192.168.1.1,rw","type": "nfs"
        },"Scope": "local"
    }
]

当我使用docker volume create手动创建卷时：

[root@oracle ~]# docker volume inspect oracle-dumps
[
    {
        "CreatedAt": "2020-08-31T02:07:14-07:00","Labels": {},"Scope": "local"
    }
]

除了标签属性，外观几乎相同。

docker inspect的容器在体积上是相同的

        {
            "Type": "volume","Name": "oracle-dumps","Source": "/var/lib/docker/volumes/foo/_data","Destination": "/otherpath/to/dir","Mode": "rw","RW": true,"Propagation": ""
        }

因此，结论是存在错误，但是在哪里？可以吗码头工人py？码头工人？

解决方法是

- name: Create dump volume
  command:
    cmd: "docker volume create --driver local --opt type=nfs --opt o=addr=192.168.1.1,rw --opt device=:/path/to/dir foo"

解决方法

问题是缺少:。设备路径应为:/path/to/dir

- name: NFS volume mount
  docker_volume:
    driver: "local"
    driver_options:
      type: nfs
      o: "addr=192.168.1.1,rw"
      device: :/path/to/dir
    volume_name: foo
