Hi,

I tried it, but when I run docker image build -t elixir/saturn ., I got the following error:

[+] Building 5.0s (7/10)

What should I do?

It looks like is failing to pull the alpine image.
can you try this and see if it succeeds?

$ docker pull alpine:3.14.2

you should get something like:

3.14.2: Pulling from library/alpine
Digest: sha256:e1c082e3d3c45cccac829840a25941e679c25d438cc8412c2fa221cf1a824e6a
