从较旧的卷创build新的容器不能按预期方式工作
这与如何升级docker容器与以前的networking和卷相关？ 。
原始的容器
$ docker inspect zealous_wozniak --format "{{ json .Mounts }}" | python -m json.tool [ { "Destination": "/etc/mast", "Driver": "local", "Mode": "", "Name": "31c0787ccded0a49e1f97e272ac5e37f2a505620b861c13318ff3a49eaef8f16", "Propagation": "", "RW": true, "Source": "/var/lib/docker/volumes/31c0787ccded0a49e1f97e272ac5e37f2a505620b861c13318ff3a49eaef8f16/_data", "Type": "volume" }, { "Destination": "/home/mast/.ssh", "Driver": "local", "Mode": "", "Name": "faaae04539b8ef338a9f6ffecc3098e79d8035d23b07065e8d86fe31bee043fa", "Propagation": "", "RW": true, "Source": "/var/lib/docker/volumes/faaae04539b8ef338a9f6ffecc3098e79d8035d23b07065e8d86fe31bee043fa/_data", "Type": "volume" } ] 升级容器

码
def upgrade_daemon_container(container_id): old_container_data = docker_api.inspect_container(container_id) creation_data = get_upgrade_data(old_container_data) new_container = docker_api.create_container( image=creation_data.get('image'), hostname=creation_data.get('hostname'), volumes=creation_data.get('volumes'), host_config=docker_api.create_host_config( binds=creation_data.get('volume_bindings'), port_bindings={80: 80}, restart_policy={"MaximumRetryCount": 0, "Name": "always"} )) return new_container
其中creation_data如下所示：
{ 'hostname': 'defb4b2697bc', 'image': 'docker.akema.fr:5000/coaxis/coaxisopt_daemon:latest', 'networking_config': { 'EndpointsConfig': { 'opt_network_aae2d4': { 'IPAMConfig': { 'IPv4Address': '10.49.0.2' } } } }, 'volumes': [ '/var/lib/docker/volumes/31c0787ccded0a49e1f97e272ac5e37f2a505620b861c13318ff3a49eaef8f16/_data', '/var/lib/docker/volumes/faaae04539b8ef338a9f6ffecc3098e79d8035d23b07065e8d86fe31bee043fa/_data' ], 'volumes_bindings': { '/var/lib/docker/volumes/31c0787ccded0a49e1f97e272ac5e37f2a505620b861c13318ff3a49eaef8f16/_data': { 'bind': '/etc/mast', 'mode': 'rw' }, '/var/lib/docker/volumes/faaae04539b8ef338a9f6ffecc3098e79d8035d23b07065e8d86fe31bee043fa/_data': { 'bind': '/home/mast/.ssh', 'mode': 'rw' } } }
题
- 为什么我有4卷而不是2？
- 为什么将旧卷作为
Destination？
我在volumes列表中混合了来源和目的地。 应该
'volumes': ['/etc/mast', '/home/mast/.ssh'],
代替：
'volumes': [ '/var/lib/docker/volumes/31c0787ccded0a49e1f97e272ac5e37f2a505620b861c13318ff3a49eaef8f16/_data', '/var/lib/docker/volumes/faaae04539b8ef338a9f6ffecc3098e79d8035d23b07065e8d86fe31bee043fa/_data' ],
