It means that the container is already running.

If we want to manage nginx, we can use docker exec directly when we enter the nginx.

Check out the help for using docker exec

[root@xinsz10] # docker exec-- help

Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

Run a command in a running container

Options:

-d,-- detach Detached mode: run command in the background

-- detach-keys string Override the key sequence for detaching a

Container

-e-- env list Set environment variables

-- help Print usage

-I-- interactive Keep STDIN open even if not attached

-- privileged Give extended privileges to the command

-t,-- tty Allocate a pseudo-TTY

-u,-user string Username or UID (format: [:])

Our more commonly used parameters are-I and-t

[root@xinsz10] # docker exec-it D1 bash # Note: D1 is the ID number of nginx just now. I took the first two digits.

Root@d1c2d8e307e7:/#

This brings you into a docker nginx terminal, which is equivalent to a shell terminal.

It's the same as shell here, with all Linux commands.

Root@d1c2d8e307e7:/# pwd

/

Root@d1c2d8e307e7:/# ls

Bin dev home lib32 libx32 mnt proc run srv tmp var

Boot etc lib lib64 media opt root sbin sys usr

Root@d1c2d8e307e7:/# which nginx

/ usr/sbin/nginx

Exit the container:

Root@d1c2d8e307e7:/# exit

Exit
