Docker RUN mkdir -p creates subdirectories with { in them

Question

In my docker file I have this command to create directories :

RUN   mkdir -p logs/{shell,security,errors}

However, it ends up creating these on my container :

{shell,security,errors}

How can I create directories without also including the curly braces?

Bash brace expansion isn't part of the [POSIX shell specification](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html). Split out the directory names as individual arguments. — David Maze, Nov 16 '22 at 10:55

You should try with shell for loop

RUN for i in shell security errors; do  mkdir "/logs/$i"; done

This should work.
