Error executing command with docker run

Hello!

I am having an issue executing this command docker run alpine cat /etc/*release* on my macOS 10.13.1.

I get a response of zsh: no matches found: /etc/*release*

When I use online playgrounds like katacoda to try the command, it works fine.

What could be wrong on my side please?

any help please? I have done so much googling to no success.

When you run that command, zsh tries to expand /etc/*release* itself instead of passing it to the command to be executed in docker. So it actually tries to look up /etc/*release* in your local MacOS installation and fails to find it, leading to that error message.
What you should actually do is run:

docker run alpine /bin/sh -c "cat /etc/*release*"

Thank you Johan.

This explains it, however, alpine uses ash for its bash so the updated command that worked is

docker run alpine /bin/ash -c “cat /etc/*release*”

No, it doesn’t :wink:

% docker run -it --rm alpine
/ # ls -l /bin/sh /bin/ash
lrwxrwxrwx    1 root     root            12 Jan 16 21:52 /bin/ash -> /bin/busybox
lrwxrwxrwx    1 root     root            12 Jan 16 21:52 /bin/sh -> /bin/busybox

Glad I could be of help.
