* Prevent extra snapshot when using new run
* Add unit tests for initializing snapshotter
There should be no snapshot for RunV2. Added a test for SingleSnapshot
as well to prove that the test actually works (rather than `initialized`
just not being read or set properly).
This commit adds the skip option for otiai10.Copy to skip the /kaniko
directory when the root is being copied. The files under /kaniko dir
should be ignored and thus this shall not cause any loss of information.
fixes: GoogleContainerTools#2033
This feature allows one to specify an https URL for any of the
digest-file options, resulting in an HTTP PUT to the provided
URL. This could for example be a (pre-signed) URL to S3 or GCS.
Currently the final digest is only written to the local filesystem,
which disappears and is not accessible when Kaniko is run in a
managed container service like AWS ECS.
By supporting https a single implementation supports all storage
services, without the need for special code for S3, GCS, etc..
Ensure zstd compression only gets applied to oci images.
When adding a layer to an image ensure that they are compatable if not convert them.
Create function to convert mediatypes between oci and docker types.
This commit changes the condition check for the behavior when no-push is
set to true while destinations are needed. Prior this change, users would
have to set destinations even when noPush option is set to true. More
specifically, a workaround for tar files to be generated when --no-push is
true and destinations is empty is provided where a dummy destination would be
set.
* Rename IgnoreListPath to MountInfoPath in config & constants
The string points to /proc/self/mountinfo
* fs_util_test.go: fix tests failing when /tmp mountpoint present
The tests
* Test_GetFSFromLayers_ignorelist
* Test_GetFSFromLayers_with_whiteouts_include_whiteout_disabled
* Test_GetFSFromLayers_with_whiteouts_include_whiteout_enabled
were failing on systems with a /tmp mountpoint:
fs_util.InitIgnoreList() adds all mountpoints to the ignore list,
but the tests were expecting file operations in a /tmp subdirectory.
This change provides an empty mountinfo list for the affected tests.
Fixes#1779
* Removed block on use --cache-copy-layers with multistage builds
* Removed using digest in composite key with command COPY --from
* COPY --from command uses src as file context (only changed files will be reason for change hash)
* ARG and ENV changed before COPY dont change composite key
* Add and fix some tests
* Caching work same as caching in docker buildx

* Add mTLS (client cert) support
Add support for Mutual TLS (mTLS) client certificate authentication.
The expected format of the new --registry-client-cert flag is the same
as the existing --registry-certificate flag, which will allow
different client certificates for different registries:
--registry-client-cert my.registry.url=/path/to/cert.crt,/path/to/key.key
* tidy: Rename mTLS (Client Cert) flag to be in line with others
This flag didn't describe that it was for the client certs uses with
the registry. Although this should be reasonably obvious, I like the
consistency with the other registry flag.
* test: Added unit tests for mTLS (Client Cert) loading
* test: Add 2 more tests for comma split formatting
since the comma splitting is a new portion of code let's make sure
that that format works well too in other cases
* tidy: Fix formatting of flag help text
* tidy: Made invalid cert format error consistent
I was running the tests and saw the message:
Failed to load client certificate/key '/path/to/client/certificate.cert' for my.registry.name, format is my.registry.name=/path/to/cert,/path/to/key
I then realized that it'd be a lot nicer if this showed the user what
they input, and how they should change it (rather than decomposing it:
Failed to load client certificate/key 'my.registry.name=/path/to/client/certificate.cert', expected format: my.registry.name=/path/to/cert,/path/to/key
* test: Fixed incorrect test argument
This didn't fail the test before because it's only attempting to show
that certs only get loaded and used for their associated registry but
it's important to keep this correct.
This case is covered by the test below, "RegistriesClientCertificates
incorrect cert format"
* doc: Add new flag to README.md
* mod: Fail to push if there was a problem loading client certs
Rather than warning that there was an issue, we should fail if the
requested client certificates were not found or failed to load.
This feels a lot better than waiting for the build to finish then
failing later.
* mod: Return an error if the certificate authority fails to load, just like client certs
The MakeTransport function was changed in the previous commit to
allow returning errors if there was a problem loading certificates,
rather than just print warnings.
This feels a lot better as you get the error immediately that there's
a problem to fix, rather than getting a warning, then later an error
that the server's certificate could not be verified.
* tidy: fix golint issues
* Add support for configurable compression algorithm (gzip, zstd) and compression level
We want to make the layer compression in kaniko configurable, so we have added two optional command line arguments “--compression” and “--compression-level”. The former allows the user to specify a compression algorithm (zstd, gzip) and the latter can be used to specify the compression level.
Depending on the selected compression algorithm and level we modify the set of layerOptions that are used to create tarball layers in `push.go` and `build.go`.
The actual implementation of the zstd support can be found in our fork of the go-containerregistry package for which we have filed this PR: google/go-containerregistry#1487
The changes should be fully backwards compatible.
* Restrict inputs for compression flag to gzip and zstd
This change will ensure that users can only specify supported compression algorithms (`zstd`, `gzip`) to the `--compression` flag.
* Fix incorrect type for switch statements on config.Compression
* somehow now the only thing that doesnt work is devices.Device

* feat(ci): Replace minikube with k3s for intregration tests
The existing setup for minikube is very complicated, replicating most of
the setup steps for a full kubernetes cluster in an only partially
supported minikube configuration (driver=none). Furthermore the existing
setup has been broken for sometime, likely, at least in part due to the
changes to CNI and CRI in recent kubernetes versions.
Since what we actually need is only a running Kubernetes cluster on the
node and access to a registry on localhost:5000, we can switch the
extremely complicated minikube setup for a lightweight cluster using
k3s. Minikube came with a default addon for running a registry on every
node, but the same is not the case for k3s, instead we make use of the
package helm controller and its HelmChart CR to deploy twuni/docker-registry.helm
and expose it on localhost using the integrated LoadBalancer controller.
* fix(test-684): pin base container version
The dockerfile for the regression test connected to issue 684 used a
rolling tag as base image, making it flaky and fail since it was
introduced.
This commit pins the base image to the digest of bionic-20200219, which,
based on the date of the commit that introduced to the dockerfile would
be the most newest ubuntu build and likely what the "rolling" tag
resolved to back then. Since this also an image from the pre-oci days of
ubuntu, this circumvents a bug in container-diff as well
(https://github.com/GoogleContainerTools/container-diff/issues/389)

* Fix resolving argument over mulit-stage build
- Building multi-stage Dockerfiles did not correctly resolve
ARG commands over different stages. Now, each stage depends on the
build arguments set by the stage before.
Closes: #1911
* Fix resolving empty arg commands
* Correctly handle platforms that include CPU variants
Prior to this change, Kaniko would only select the platform-specific
image from a multi-platform image using the OS and architecture to
select the image. This leads to problems when there are two platforms
that are indistinguishable using only this information (e.g.,
linux/arm/v5 and linux/arm/v7).
This change more explicitly selects the right image from a
multi-platform image, taking CPU variant into account (v5 vs v7), using
containerd's CPU variant detection logic.
This also moves platform defaulting up as early as possible in execution
as it can go, so that malformed platform values are detected as soon as
possible.
* set platform in unit test
The directory created by `T.TempDir` is automatically removed when the

* Remove tarball.WithCompressedCaching flag to resolve OOM Killed error
Large images cannot be build as the kaniko container will be killed due to an OOM error. Removing the tarball compression drastically reduces the memory required to push large image layers. Fixes#1680
This change may increase the build time for smaller images. Therefore a command line option to trigger the compression or a more intelligent behaviour may be useful.

* Fix composite cache key for multi-stage copy command (#1706)
PR #1518 reintroduced COPY layers caching using the `--cache-copy-layers`
flag. Unfortunately, this PR also introduced a bug by not including the
stage digest into the caching key of the COPY command when the
`--cache-copy-layers` flag was not set. As a result, kaniko would use
any previous (possibly stalled) layer from the cache because the digest
of the "COPY --from" command would never change.
PR author probably expected Go to fallthrough in the switch just like C
does. However, this is not the case. Go does not fallthrough in
switch-statements by default and requires the fallthrough keyword to be
used. Note that this keyword is not available in type-switches though,
because it wouldn't work properly with typings.
* refactor: add an abstract copy command interface to avoid code duplication
