Always include arguments when running docker-compose run

Question

I have a question regarding the passing of arguments in docker-compose run:

I'm using a Dockerfile that has the following entrypoint:

ENTRYPOINT ["/ bin / wp"]
CMD ["--allow-root", "--help"]

I need --allow-root to ALWAYS be included.

If I run docker-compose run [service], the argument goes by default. But if I run docker-compose run [service] option (option option ...) I need to include the argument manually.

Have you ALWAYS include the argument? Do I need to edit Dockerfile (I'm not the author) or can I do it via docker-compose? I tried the command following this answer, but it didn't not succeed.

the ENTRYPOINT is what is run when starting the container and the CMD appends to entrypoint. So if you add --allow-root to entrypoint it should be enough

ENTRYPOINT ["/ bin / wp --allow-root"]

If CMD appends to the entrypoint, shouldn't it always get appended anyway? Why it is only appended when I don't add extra arguments? – That Brazilian Guy Mar 01 '18 at 23:39
Besides, I don't own the dockerfile and can't edit it. – That Brazilian Guy Mar 01 '18 at 23:40

`CMD` is something you usually override with run.... but since you know the image name, you can create own Dockerfile use the base image from that and write own ENTRYPOINT – Mazel Tov Mar 02 '18 at 08:00
