Build image from scratch #873

Open etnbrd opened 6 years ago

ISSUE TYPE

Is it possible to build images from scratch with ansible-container ?

Based on this issue #52 mentionning an --from-scratch option, I am under the impression that it is possible, but can't find the relative documentation (no mention in the build documentation)

How could one provide a rootfs tarball instead of a base image, to build images from scratch ?

etnbrd commented 6 years ago

I was used to acbuild way of providing the tarball, and missed this issue #107 that specifies that the from directive from container.yml is equivalent to the FROM from a dockerfile.

So the way to do this with ansible-container and Docker would be to specify from: scratch, and then a role with the tarball.

Feel free to close this issue if this is correct.

That's more or less accurate. I'd be interested to hear how this goes for you.

Trying to use from: scratch in container.yml , ansible-container tries to pull the scratch image, the scratch image used to be a regular image, but as of commit 8936789 it is a special case, and cannot be used with 'docker pull.' Failed to pull scratch: 500 Server Error: Internal Server Error ("'scratch' is a reserved name")

Did I miss something? Flag, configuration setting?

Nope. You didn't miss anything - I did. Thanks for pointing me to that commit. sigh

My advice would be to roll your own scratch. It should be straightforward. Something like:

tar -czf - --files-from /dev/null | docker import - my-scratch

Good luck!

Thanks, my-scratch looks good, have used tianon/true for testing. I get this error when trying to apply any role to the my-scratch or tianon/true image:

docker.errors.APIError: 500 Server Error: Internal Server Error ("linux spec user: unable to find user root: no matching entries in passwd file")

My role just tries to copy some file into the container.
