kaniko: error building image: error building stage: failed to execute command: extracting fs from image: removing whiteout .wh.dev: unlinkat //dev/pts/ptmx: operation not permitted

Actual behavior error building image: error building stage: failed to execute command: extracting fs from image: removing whiteout .wh.dev: unlinkat //dev/pts/ptmx: operation not permitted

Expected behavior Build finishes without error.

To Reproduce Steps to reproduce the behavior:

Enable Kaniko and set version:

gcloud config set builds/use_kaniko True
gcloud config set builds/kaniko_image gcr.io/kaniko-project/executor:v0.17.1

Start build:

gcloud builds submit --tag gcr.io/project_id/test_image

Build is finished.
Start build again.
Consistently see the same error message for all subsequent builds.

Additional Information Dockerfile:

FROM nginx:1.17.8-alpine
LABEL name="test_image"
RUN rm -rf /etc/nginx/conf.d/* && rm -rf /usr/share/nginx/html

Kaniko image:

Pulling image: gcr.io/kaniko-project/executor:v0.17.1
v0.17.1: Pulling from kaniko-project/executor

@cvgw the version a1af057 that you linked solved the issue I had,

but - seems to break switching users, the HOME env var is not changed.

This simple docker file illustrates the issue,
FROM alpine
RUN adduser -S -D myuser

RUN echo $HOME
RUN whoami

USER myuser

RUN echo $HOME
RUN whoami
If you run it with latest (or docker build), HOME correctly updates to /home/myuser, with a1af057... it is still /root.

~I’m not able to repro this bug using tag a1af057f997316bfb1c4d2d82719d78481a02a79~

Dockerfile

FROM alpine
RUN adduser -S -D myuser

USER myuser

Docker command

docker run \
  -v $LOCAL_CONTEXT:/workspace
  gcr.io/kaniko-project/executor:a1af057f997316bfb1c4d2d82719d78481a02a79 \
  --context dir:///workspace/ \
  --dockerfile Dockerfile \
  --destination $DESTINATION \
  -v info

Test

$ docker run --rm $DESTINATION /bin/sh -c 'echo $HOME'
=> /home/myuser

~@mcfedr am I missing something from the repo steps or interpreting the test result wrong?~

This is the same problem as #1082 $HOME is not set correctly during the build, but is correct in the final image.

Works fine when I dropped the cache by deleting $DOCKER_IMAGE/cache tags.
