docker - 为 Docker 守护进程分配标签

Question

如何为 Ubuntu 上已经运行的 Docker 守护进程分配标签？

尝试:

export DOCKER_OPTS="--label=com.example.storage=ssd"
sudo restart docker

但没有帮助。 docker info需要出示 Labels .

docker configuration section清楚了:

• Log into your host as a user with sudo or root privileges.
• If you don’t have one, create the /etc/default/docker file on your host. Depending on how you installed Docker, you may already have this file.
• Open the file with your favorite editor.

    $ sudo vi /etc/default/docker

• Add a DOCKER_OPTS variable with the following options. These options are appended to the docker daemon’s run command.

    DOCKER_OPTS="--label=com.example.storage=ssd"

• Save and close the file.
• Restart the docker daemon.

    $ sudo restart docker
