Additional Information

  1. empty is an empty file. touch empty
  2. kaniko's call: /kaniko/executor --context /docker --no-push --oci-layout-path /container --reproducible
  3. Dockerfile:
FROM scratch
FROM scratch
COPY empty /

Triage Notes for the Maintainers
I didn't try with --cache

Description Yes/No
Please check if this a new feature you are proposing
Please check if the build works in docker but not in kaniko
Please check if this error is seen when you use --cache flag
Please check if your dockerfile is a multistage dockerfile

Altered issue description to use scratch instead of alpine image.

@paisleyrob I created the same context from outside the container, and ran kaniko

docker run --rm -it \
  --volume $HOME/ctxt:/build \
  gcr.io/kaniko-project/executor:debug- v0.19.0@sha256:0d0e34396f47ec6d5fd75aebb9772147a78d96ed2bbb16ec892bd178efdc8307 
  --oci-layout-path /container \
  --reproducible \
  --no-push \
  --context=/build

where my /ctxt directory contained your Dockerfile and "empty". The build successfully finishes.
Generally, this is the recommended way to run Kaniko within a docker.

Please let me know if the issue can be closed.

I had to edit your command a little as follow to make it work:

docker run --rm -it     \

    gcr.io/kaniko-project/executor:debug-v0.19.0@sha256:0d0e34396f47ec6d5fd75aebb9772147a78d96ed2bbb16ec892bd178efdc8307 \

Which worked.

I'm not comfortable closing this issue as I'm using this in a GitLab Runner environment, so I need it work from the kaniko debug image's shell, which it doesn't.

Any updates on this? Still encountering this with the latest executor:debug

I mistook this for a request to see if it's still encountered on the latest and I came here to confirm, yes it's still a problem. v1.3.0 doesn't work either:

I had a quick play, and:

  • The name of the directory doesn't matter.
  • If I use the same reproduction, but with /docker mounted as a volume, it no longer fails.
  • If I use the same reproduction, but with /docker/test, the /docker directory is deleted:

So I suspect this is not to do with the use of --entrypoint, but relates to something Kaniko is doing with mount-point detection, that causes the "Deleting filesystem..." step to accidentally delete the directory in the root that contains the context, if it's not under a mount-point. Presumably there's code around that is walking up the tree to find a mount-point, but which doesn't correctly handle the case of "the mount point was /".

The only relevant differences in the trace logs are around the mount-point lists, and I think debug logs would have shown them.

Working case:

Failure case:

The difference is the presence of {/docker false} (that bool is PrefixMatchOnly).

This is the bug: DeleteFilesystem appears to be designed to delete everything from the filesystem that isn't in the ignore list. And the ignore list is built from mountpoints plus some defaults. Annoyingly, DeleteFilesystem is missing a debug log in the relevant branch, otherwise this would be very visible in the debug logs.

So I suspect a fix would be to automatically add the context directory to the ignore list. A build-from-git must already do this, or it pulls the context into an existing ignored directory (the latter is probably the case).

A workaround might be to bind-mount the context to itself before populating it, but I couldn't get that to work, trivially.

> docker run --rm -it --entrypoint /busybox/sh gcr.io/kaniko-project/executor:debug
/ # mkdir /docker
/ # mount -o bind /docker /docker
mount: permission denied (are you root?)

On the other hand, now that I know that Kaniko treats its own root as the image root, the following pathological feature works:

Minor tweaks as WORKDIR now seems to be /workspace but this issue still exists with v.1.7.0:

The above comment from @TBBle appears to pinpoint underlying issue.

@paisleyrob @TBBle thanks for digging into this.

Unfortunately this project is pretty short-staffed, so if you can find where in the code this is going wrong, or a recent commit that made it go wrong, that would be very helpful. I don't think there's anybody coming to save us here but us.

I'm not personally very familiar with the code, but I'd be happy to chat over Slack or video chat if you want to dig in together and throw around ideas.

I just ran into a very similar-sounding issue: I'm trying to COPY --from=previous_stage $CI_PROJECT_DIR/some_folder $CI_PROJECT_DIR/some_folder in a Dockerfile built with Kaniko in Gitlab CI, where some_folder is either a Python .venv folder or an npm node_modules folder and $CI_PROJECT_DIR has been set to the same value as Gitlab's predefined variable of the same name (i.e. /builds/path/to/my/project). This yields

error building image: error building stage: failed to execute command: resolving src: failed to get fileinfo for /kaniko/2/builds/builds/path/to/my/project/.venv: lstat /kaniko/2/builds/path/to/my/project/.venv: no such file or directory

(Meanwhile, building in Docker works fine.)

This did not happen before when my .venv / node_modules folder was under a different path (/workdir) in the previous stage and also got COPY'ed to /workdir/.venv, so given that $CI_PROJECT_DIR is somewhat special in Gitlab CI, there seems to be some interaction between Kaniko and Gitlab CI going on here?

People have complained about similar issues here:

EDIT: It seems I have found a workaround: If in previous stages I use a source folder different from $CI_PROJECT_DIR, then Kaniko will happily COPY --from=previous_stage $NEW_SOURCE_FOLDER/some_folder $CI_PROJECT_DIR/some_folder. So, using $CI_PROJECT_DIR as destination folder of the COPY operation is okay, but using it as the source folder causes trouble for some reason.

Hi @codethief,

I'm running into a similar error. Could you share the relevant parts from your gitlab-ci yaml file and the Dockerfile that now works for you? That would be awesome!

Previous copy statements (with --from kaniko) work but the last one fails. docker-entrypoint.sh is in the same folder as my Dockerfile.

I found this issue while trying to debug an issue - similarly with building from a GitLab Runner. The error-message was similar to what I see here:

error building image: error building stage: failed to get files used from context: failed to get fileinfo for /kaniko/2/app/public: lstat /kaniko/2/app/public: no such file or directory

The real issue was that /app/public was empty, so Kaniko didn't save the directory for a later stage, and would therefore error out, where docker build would have no trouble with copying in an empty directory from a previous stage.

Hope this helps someone.

@anneadb My apologies for the delay; for some reason I never got notified about your message!

I am afraid I don't remember anymore the full context of the issues I encountered or how I ended up solving them, let alone whether I actually saw the bug that the present bug report is about. I have run into so many Gitlab bugs and sometimes also Kaniko bugs in the last months, that it's difficult to recall things sometimes. 😅

In any case, what I can tell you is that one should absolutely avoid putting any files in $CI_PROJECT_DIR inside a Docker image, since – when the image is later used in a CI job – Gitlab will mount an outside volume there (the cloned repository) and the files won't be visible, anyway. Unfortunately, if you use a different WORKDIR for your image (say, /workdir), you might then run into a whole bunch of other Gitlab issues and need to build workarounds for those. I started keeping track of Gitlab bugs in my notes, so here is an excerpt:

Again, I'm not sure what ended up resolving the specific issues I mentioned in my previous message but today we no longer use $CI_PROJECT_DIR in any of our Dockerfiles for the reason I mentioned above, and things generally seem to work fine. (Of course, correlation != causation.) The exception to this is this Kaniko bug, which still hits us occasionally, and also that one.

Sorry I can't be of greater help!
