无法将自己添加到 docker 组

我确认该docker组存在

$ grep -i docker /etc/group
docker:x:130:

但是当我尝试时usermod -aG docker，我得到了使用输出

$ sudo usermod -aG docker

Options:
  -c, --comment COMMENT         new value of the GECOS field
  -d, --home HOME_DIR           new home directory for the user account
  -e, --expiredate EXPIRE_DATE  set account expiration date to EXPIRE_DATE
  -f, --inactive INACTIVE       set password inactive after expiration
                                to INACTIVE
  -g, --gid GROUP               force use GROUP as new primary group
  -G, --groups GROUPS           new list of supplementary GROUPS

                                mentioned by the -G option without removing
                                him/her from other groups
  -h, --help                    display this help message and exit
  -l, --login NEW_LOGIN         new value of the login name

  -u, --uid UID                 new UID for the user account

  -W, --del-subgids FIRST-LAST  remove range of subordinate gids
  -Z, --selinux-user SEUSER     new SELinux user mapping for the user account

当我id检查时，我不是该docker组的成员。

我错过了什么？

缺少必需的参数

也许你需要指定LOGIN, 必需的参数看到在'用法：'信息。

太长了；博士

  • usermod -a -G docker <your username>

也可以看看：

  • gpasswd -a <your username> docker

不要忘记再次登录或使用newgrp docker以确保此操作生效。
