miniconda3 on alpine linux

[Maxyme]

Would it be possible to add a version of the dockerfile using alpine linux instead of full debian? This would make it much faster to download and upload.

See example for redis on alpine:
https://github.com/docker-library/redis/blob/6cb8a8015f126e2a7251c5d011b86b657e9febd6/3.2/alpine/Dockerfile

@Maxyme Not maintainer, but FYI. I've tried building on both alpine and debian... the size difference is pretty minimal.

[andreacassioli]

@jontonsoup Could you share the Dockerfile?

[andreacassioli]

Just to mention, from docker image ls

• python3 alpine : 92MB
• continuumio/miniconda3: 571MB

Either miniconda is not that minimal, or alpine is much smaller, or both!

[jontonsoup]

@andreacassioli i threw it out after the test, but your comparison above is not accurate. python 3 alpine doesn't include all the dependencies miniconda includes. Its not a fair comparison. In my experience, its all the libraries that take up the space.

[mingwandroid]

Also continuumio/miniconda3: 571MB is wrong, we use hardlinks, I suspect you are counting them twice.

[mingwandroid]

Oh and we also keep the tarballs present for all packages, these can be cleaned via conda if you are attempting to reduce a docker image size. Miniconda is comprised of about 33 packages.

[andreacassioli]

@mingwandroid Thanks for the suggestion! It would be nice if Continuum could provide a microconda image. I mean, of course one could go an tweak it, but if you could work out a very minimal image would be great.

[msarahan]

We do, actually: https://hub.docker.com/r/continuumio/miniconda/

See also #77, which shaves of 70MB or so

Miniconda is not that minimal. It outweighs the entire debian image by several times. I don't think that debian vs alpine is yes the limiting factor.

[OrangeDog]

This has been done.
continuumio/miniconda3:4.7.12 is 151MB
continuumio/miniconda3:4.7.12-alpine is 55MB

[mrocklin]

Nice.

awesome
