centos7 - docker 密码是怎么设置的？

Question

通过自有云主机接入docker，提示需要输入密码:

[sudo] password for docker

这个密码是怎么设置的？

Answer 1

Normally, it is recommended to use docker-machine ssh default 进行登录，不需要输入密码。default as the default machine name.

In boot2docker, the default username and password are:

user: docker
pass: tcuser

Login method:

$ ssh docker@localhost -p 2022
docker@localhost's password: tcuser
                        ##        .
                  ## ## ##       ==
               ## ## ## ##      ===
           /""""""""""""""""\___/ ===
      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~ ~ /  ===- ~~~
           \______ o          __/
             \    \        __/
              \____\______/
