This article shares with you the content of the sample code for command in docker. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Install ssh

Error:

Root@cloud1:~# ssh root@cloud1ssh: connect to host cloud1 port 22: Connection refusedroot@cloud1:~# source. / .bashrc Missing privilege separation directory: / var/run/sshd

Solution:

Mkdir / var/run/sshdchmod 0755 / var/run/sshd

Modify parameters

Once the docker container is started, the parameters cannot be changed. awkward.

# source ~ / .bashrc sh: 14: source: not found

Command prompt in ubuntu-upstart? Is #, and shell is dash. Enter "bash" to switch to bash environment, and the source command can be used normally.
