如何为Ubuntu上已经运行的Docker守护程序分配标签？

尝试：

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

但没有帮助. docker info需要显示标签.

最佳答案
docker configuration section很清楚：

• 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
