5cacf0fcec dockerTools: use go.GOARCH as default arch 2020-12-15 02:15:35 -08:00

8f66dc94a7 dockerTools: normalize arch to GOARCH
Docker (via containerd) and the the OCI Image Configuration imply and
suggest, respectfully, that the architecture set in images matches those
of GOARCH in the Go Language document.

This changeset updates the implimentation of getArch in dockerTools to
return GOARCH values, to satisfy Docker.

Fixes:

f7ee2706c2 dockerTools.fakeNss: init
This provides a /etc/passwd and /etc/group that contain root and nobody.

Useful when packaging binaries that insist on using nss to look up
username/groups (like nginx).

The current nginx example used the `runAsRoot` parameter to setup
/etc/group and /etc/passwd (which also doesn't exist in
buildLayeredImage), so we can now just use fakeNss there and use
buildLayeredImage.

Informational messages belong on stderr, not on stdout and intermixed
with structured output for programmatic use.

8c0459f611 dockerTools: Always set imageTag attribute
The image tag can be specified or generated from the output hash.
Previously, a generated tag could be recovered from the evaluated
image with some string operations.

However, with the introduction of streamLayeredImage, it's not
feasible to compute the generated tag yourself.

With this change, the imageTag attribute is set unconditionally,
for the buildImage, buildLayeredImage, streamLayeredImage functions.

886c92332c dockerTools: Properly add /nix/ and /nix/store/ first to layer.tar
In https://github.com/NixOS/nixpkgs/pull/58431 the authors ensured that
the resulting layer.tar would always list

  /nix/
  /nix/store/

first to fully comply to the tar spec. Various refactorings later it is only
ensured to create /nix/ but NOT /nix/store anymore. Instead tar transformed
them to /nix/nix and /nix/nix/store.

dockerTools: Calculate tarsum's on the fly
Calculating the tarsum after creating a layer is inefficient, since
we have to read the tarball we've just written from the disk.

This commit simultaneously calculates the tarsum while creating the
tarball.

dockerTools.buildLayeredImage: Avoid appending to tarballs when building layers
Appending to an existing tar archive repeatedly seems to be a quadratic
operation, since tar seems to traverse the existing archive even using
the `-r, --append` flag. This commit avoids that by passing the list of
files to a single tar invocation.

3b65b3f6d6 dockerTools.buildLayeredImage: store all paths passed in final layer
Fixes 

My previous change broke when there are more packages than the maximum
number of layers. I had assumed that the `store-path-to-layer.sh` was
only ever passed a single store path, but that is not the case if
there are multiple packages going into the final layer. To fix this, we
loop through the paths going into the final layer, appending them to the
tar file and making sure they end up at the right path.
