Docker: Create bucket and set global policy

[tillkruss]

I'm not sure if this is the right place to ask questions, I'm sorry if it isn't.

I would like to create a bucket and set a global policy (for all future uploaded files) when the Minio docker container is build. Is that possible?

This is my Minio setup in my docker-compose.yml:

minio:
  image: minio/minio
  volumes:
    - minio:/data
  ports:
    - "9001:9000"
  environment:
    - MINIO_ACCESS_KEY=minio
    - MINIO_SECRET_KEY=password
  command: server /data

@harshavardhana: Thanks!

So I would just run this?

entrypoint: >
  /bin/sh -c "
  /usr/bin/mc mb acme;
  /usr/bin/mc policy public acme;
  "

You need to configure mc properly first with an alias @tillkruss https://docs.minio.io/docs/minio-client-quickstart-guide can help you.

I'm a little confused of trying to run /usr/bin/mc mb acme; since there is no minio client installed in the docker container by default.

You'll end up getting the output /bin/sh: /usr/bin/mc: not found since mc isn't in that directory.

I know you could potentially alias to only need to run mc by itself, but it appears that mc isn't even on the image. minio is, but that is only used to run the server. I see that there's a minio client image https://hub.docker.com/r/minio/mc/. Do I have to run that service as well apart of the network and have it create the initial bucket? It seems like a heavy way to just create the bucket once for the lifetime of the container.

EDIT: I realized that the link https://gist.github.com/harshavardhana/cb6c0d4d220a9334a66d6259c7d54c95 in fact does use the mc image to perform this action. It still feels heavy to have a container dedicated for a single task that will be run once but it's worth it for us at the moment.

You can alternatively download the mc as well.

It seems like a heavy way to just create the bucket once for the lifetime of the container.

Also I don't think its heavy, its an alpine Linux container which is 5MiB compressed.

I thought the container remained running but since it only stays online as long as it's needed makes me feel better about it :)

Closing this as answered feel free to open new issues if you have further questions @tillkruss

[tillkruss]

No, thanks. I got it working.

I ended up installing mc inside my workspace container and execute the commands manually.

Having an entire container just for mc seemed unessesary.
