How to give write permission to docker folder?

Question

Docker

there was a need to create a separate folder (folder) directly in the docker container.
there is a docker-compose.yml file, the question is how and where can I set write permissions to this folder (folder)?
Should I create a dockerfile, if so, how to reference it in docker-compose.yml ?

Answer 1

task is not clear.
do you need to create a folder while working or when creating a container?
if the first - well, create, what's the problem.
if the latter, then you will have to add the appropriate directive to the Dockerfile and rebuild the container.
or in general the third option, do you need to fumble a certain folder between several containers?
then in docker-compose.yml you need to describe the joint volume
