login the container to
[root@bugzilla /]# curl http://localhost/bugzilla/

http://10.145.101.61:30399/bugzilla/ the home page works
the home page works and I can login with username is [email protected] and the password is password.

Seems the sshd can not work.

I login the container and test
[root@bugzilla /]# ssh bugzilla@localhost -p 22
ssh: connect to host localhost port 22: Connection refused

later I find the
