Expected behavior We were able to build the same docker file using the docker build command.

2. Build the Dockerifle using the kaniko agents, docker run -ti --rm -v ${PWD}:/workspace gcr.io/kaniko-project/executor:debug --no-push --dockerfile=/workspace/Dockerfile --context=dir:///workspace/ --verbosity=trace
