Even though the same file is used can anyone check this if something is wrong with my dockerfile

CodePudding user response：

The local build and the pipeline build are launching from different paths, but both are provided with the same . relative build context, which means they resolve to different paths.

To emulate the local build, supply the equivalent "build context" paramater

docker build -t $CI_DOCKER_REPO:$CI_COMMIT_SHORT_SHA \
  -f ./cronTest/Dockerfile \
  ./crontTest

Or move into the same directory

cd cronTest
docker build -t $CI_DOCKER_REPO:$CI_COMMIT_SHORT_SHA \
  -f Dockerfile \
  .

update to the following, but can't help much further without full context of structure

COPY ./package.json ./
