Antoine Eiche d44b778d10 dockerTools.examples: explicitly set image tag to fix docker-tools tests
docker-tools tests load images without specifying any tag
value. Docker then uses the image with tag "latest" which doesn't
exist anymore since commit 39e678e24e.

lewo 0644b4d948 dockerTools.pullImage: expose image* attributes (#41366)
Attributes `imageName` and `imageTag` are exposed if the image is
built by our Nix tools but not if the image is pulled. So, we expose
these attributes for convenience and homogeneity.

Antoine Eiche 8f71ce7e80 skopeo: 0.1.29 -> 0.1.30
Skopeo used by our docker tools was patched to work in the build
sandbox (it used /var/tmp which is not available in the sandbox).
Since this temporary directory can now be set at build time, we remove
the patch from our docker tools.

Samuel Dionne-Riel 60737bd319 dockerTools: fixes extraCommands for mkRootLayer.
The extraCommands was, previously, simply put in the body of the script
using nix expansion `${extraCommands}` (which looks exactly like bash
expansion!).

This causes issues like in #34779 where scripts will eventually create
invalid bash.

The solution is to use a script like `run-as-root`.

Fixes #34779

dockerTools.pullImage: Fix build with sandboxing
Regression introduced in 736848723e.

This commit most certainly hasn't been tested with sandboxing enabled
and breaks not only pullImage but also the docker-tools NixOS VM test
because it doesn't find it's certificate path and also relies on
/var/tmp being there.

Fixing the certificate path is the easiest one because it can be done
via environment variable.

I've used overrideAttrs for changing the hardcoded path to /tmp (which
is available in sandboxed builds and even hardcoded in Nix), so that
whenever someone uses Skopeo from all-packages.nix the path is still
/var/tmp.

The reason why this is hardcoded to /var/tmp can be seen in a comment in
vendor/github.com/containers/image/storage/storage_image.go:

  Do not use the system default of os.TempDir(), usually /tmp, because
  with systemd it could be a tmpfs.

With sandboxed builds this isn't the case, however for using Nix without
NixOS this could turn into a problem if this indeed is the case.

So in the long term this needs to have a proper solution.

In addition to that, I cleaned up the expression a bit.

Tested by building dockerTools.examples.nixFromDockerHub and the
docker-tools NixOS VM test.

Antoine Eiche 736848723e dockerTools.pullImage: Skopeo pulls images by digest
Skopeo is used to pull images from a Docker registry (instead of a
Docker deamon in a VM).

An image reference is specified with its name and its digest which is
an immutable image identifier (unlike image name and tag).

Skopeo can be used to get the digest of an image, for instance:
$ skopeo inspect docker://docker.io/nixos/nix:1.11 | jq -r '.Digest'

Antoine Eiche 346996ceec dockerTools: dereference hard links in tar archives
This is to improve image creation reproducibility. Since the nar
format doesn't support hard link, the tar stream of a layer can be
different if a dependency of a layer has been built locally or if it
has been fetched from a binary cache.

If the dependency has been build locally, it can contain hard links
which are encoded in the tar stream. If the dependency has been
fetched from a binary cache, the tar stream doesn't contain any hard
link. So even if the content is the same, tar streams are different.

Revert "dockerTools.pullImage: use skopeo to pull the image"
This reverts commit 01174c5f4d.

therefore amongst others mesos.

Antoine Eiche 35f205a4b6 dockerTools.buildImage: Switch to the format image generated by Skopeo
We were using 'Combined Image JSON + Filesystem Changeset Format' [1] to
unpack and pack image and this patch switches to the format used by the registry.

We used the 'repository' file which is not generated by Skopeo when it
pulls an image. Moreover, all information of this file are also in the
manifest.json file.
We then use the manifest.json file instead of 'repository' file. Note
also the manifest.json file is required to push an image with Skopeo.

Fix #29636

Antoine Eiche cb6fc52f99 dockerTools.buildImageWithNixDb: Make output paths valid and add gcroots
The database dump doesn't contain sha and size. This leads to invalid
path in the container. We have to fix the database by using
nix-store.
Note a better way to do this is available in Nix 1.12 (since the
database dump contains all required information).

We also add content output paths in the gcroots since they ca be used
by the container.

Antoine Eiche df589a438e dockerTools.buildImageWithNixDb: populate the Nix Db of the image Nix store
Currently, the contents closure is copied to the layer but there is no
nix database initialization. If pkgs.nix is added in the contents,
nix-store doesn't work because there is no nix database.

From the contents of the layer, this commit generates and loads the
database in the nix store of the container. This only works if there
is no parent layer that already have a nix store (to support several
nix layers, we would have to merge nix databases of parent layers).

We also add an example to play with the nix store inside the
container. Note it seems `more` is a missing dependency of the nix
package!

Antoine Eiche 01174c5f4d dockerTools.pullImage: use skopeo to pull the image
Before this patch, a VM was used to spawn docker that pulled the
VM. Now, the tool Skopeo does this job well so we can simplify our
dockerTools since we doesn't need Docker anymore:)

This also fixe the regression described in
https://github.com/NixOS/nixpkgs/issues/29271 : cntlm proxy doesn't
work in 17.09 while it worked in 17.03.

Note Skopeo doesn't produce the same output than docker pull so, we
have to update sha.

Antoine Eiche 132e790735 dockerTools.pullImage: change the docker deamon readiness mechanism
To wait for the docker deamon, curl requests are sent. However, if a
http proxy is set, it will respond instead of the docker daemon.
To avoid this, we send docker ps command instead of curl command.

Mathias Schreck 86d9b09c9b dockerTools: fix image json and manifest
The image json is not exactly the same as the layer json, therefore I
changed the implementation to use the `baseJson` which doesn’t include
layer specific details like `id`, `size` or the checksum of the layer.

Also the `history` entry was missing in the image json. I’m not totally
sure if this field is required, but a I got an error from a docker
registry when I’ve tried to receive the distribution manifest of an
image without those `history` entry:

GET: `http://<registry-host>/v2/<imageName>/manifests/<imageTag>`

```json
{
  "errors": [
    {
      "code": "MANIFEST_INVALID",
      "message": "manifest invalid",
      "detail": {}
    }
  ]
}
```

I’ve also used a while loop to iterate over all layers which should make
sure that the order of the layers is correct. Previously `find` was
used and I’m not sure if the order was always correct.

Tim Stewart 5ca1646bb0 docker: improve reproducibility of layers
This patch fixes file modification times to $SOURCE_DATE_EPOCH, and
ensures that files originating from the store are owned by root:root.
Both changes improve reproducibility, and the latter allows proper
building on a host where the store is owned by a non-root user.
