Description Adam Kaplan 2019-05-14 17:46:18 UTC
+++ This bug was initially created as a clone of Bug #1707941 +++

Description of problem:
in a dockerfile,
COPY . .

is failing in some cases.

How reproducible:

Steps to Reproduce:
1. git clone git:operator-framework/helm.git
2. buildah bud .
3. see failure:
error building at STEP "COPY . .": error copying "/home/bparees/git/gocode/src/github.com/openshift/helm/pkg/chartutil/testdata/joonix/charts/frobnitz" to "/home/bparees/.local/share/containers/storage/vfs/dir/a95fa17f13262c63706f22e35a8c0186a522bff0df57c97028c88867df39bd02/go/src/k8s.io/helm": Can't copy a directory

4. docker build .
5. see success

Actual results:
buildah bud fails, docker build succeeds. 

Expected results:
both should succeed

Additional info:

This is a blocker for OCP4.1 because ocp image builds are experiencing the same failure.  buildah is just an easy reproducer.

There are also similar looking cases of COPY that seem to work fine:

git clone git:openshift/elasticsearch-operator.git
buildah bud .

succeeds despite doing pretty much the same COPY operation: https://github.com/openshift/elasticsearch-operator/blob/master/Dockerfile#L3

I am also seeing a slightly different issue on these repos, but the overall effect is the same in that docker builds them fine, buildah fails:

It looks like the handling of .dockerignore files has difficulty with symbolic links (and probably other non-directory, non-regular items).

--- Additional comment from chris alfonso on 2019-05-08 20:22:05 UTC ---

Based upon your investigation, I'd like to move this to 4.2 as we wouldn't hold the GA release for this fix.

--- Additional comment from Ben Parees on 2019-05-08 22:45:17 UTC ---

Just to clarify the impact of this bug, based on my understanding from Nalin:

if you have a image build context directory containing:

1) a .dockerignore
2) a symlink (or other "unusual" file type)

and then you do a
COPY . /somedir

in your dockerfile.

Then your build will fail.  It does not matter if the .dockerignore references the symlink or not.

For the RUN issue, we should split it out into a separate (4.1.z+4.2.0) targeted bug as it's an unrelated issue and less severe in terms of likely users impacted.

--- Additional comment from Nalin Dahyabhai on 2019-05-09 15:30:30 UTC ---

https://github.com/containers/buildah/pull/1583 should fix the issues with symbolic links.

--- Additional comment from Nalin Dahyabhai on 2019-05-13 14:15:17 UTC ---

https://github.com/openshift/builder/pull/72 should merge the fix into the builder.

Verified it in image build side in version:
$ oc get clusterversion
NAME      VERSION                             AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.1.0-0.nightly-2019-05-16-223922   True        False         5h58m   Cluster version is 4.1.0-0.nightly-2019-05-16-223922

1.Create a new build, which dir had symlink and .dockerignore file.
  $oc new-build  https://github.com/wewang58/dockerignore2
2. Build complete
