dockerTools: fix build (#109420) 2021-01-15 03:56:38 +01:00
Robert Hensing a31607f904 dockerTools: Don't apologize
Warning about future breaking changes is wrong.

 - It suggests that the maintainers don't value backwards compatibility.
   They do.
 - It implies that other parts of Nixpkgs won't ever break. They will.
 - It implies that a well-defined "public" interface exists. It doesn't.
 - If the reasons above didn't apply, it should have been in the manual
   instead.

Breaking changes will come, especially to the interface. That can be the
only way we can make progress without breaking the image _contents_.

I don't think dockerTools is any different from most of Nixpkgs in
these regards.

Sarah Brofeldt ffe5ff6009 dockerTools: Test buildLayeredImage with symlinks
This exercises layer creation in face of store path symlinks, ensuring
they are not dereferenced, which can lead to broken layer tarballs

Sarah Brofeldt 08b0d02944 dockerTools: Fix streamLayeredImage for symlinks
When archiving `/nix/store/foo` and `foo` is itself a symlink, we must
not traverse the symlink target, but archive the `foo` symlink itself

Robert Hensing 5cacf0fcec dockerTools: use go.GOARCH as default arch 2020-12-15 02:15:35 -08:00
Terin Stock 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: #106695

Florian Klink 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.

edef de88771a7d nix-prefetch-docker: output informational messages to stderr
Informational messages belong on stderr, not on stdout and intermixed
with structured output for programmatic use.

dockerTools.streamLayeredImage: Store the customisation layer as a tarball
This fixes as issue described here[1], where permissions set by 'extraCommands'
were ignored by Nix.

Robert Hensing 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.

Alex Biehl 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.

Antoine Eiche 9ac444d80e dockerTools.examples: fix the nginx image
Nginx now requires directories `/var/log/nginx` and `/var/cache/nginx`
to be existing.

The objective is to fix the test `nixosTests.docker-tools`.

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.
