Expected behavior

I am trying to start hadolint container using below command

docker create --name 9a37a772568f45f2ba181180907608fc_hadolinthadolint_6be07c --workdir /__w/docker-base-images/docker-base-image --entrypoint "tail" hadolint/hadolint "-f" "/dev/null"

docker start 9a37a772568f45f2ba181180907608fc_hadolinthadolint_6be07c

But It fails with below error:

Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: exec: "tail": executable file not found in $PATH: unknown Error: failed to start containers: 9a37a772568f45f2ba181180907608fc_hadolinthadolint_6be07c

Actual behavior

the container should start without showing error on tail not found.

Steps to reproduce the behavior

docker create --name 9a37a772568f45f2ba181180907608fc_hadolinthadolint_6be07c --workdir /__w/docker-base-images/docker-base-image --entrypoint "tail" hadolint/hadolint "-f" "/dev/null"

docker start 9a37a772568f45f2ba181180907608fc_hadolinthadolint_6be07c

Output of hadolint --version or
docker run --rm hadolint/hadolint hadolint --version or
docker run --rm ghcr.io/hadolint/hadolint hadolint --version:

[lorenzo]

The docker image does not have a shell or any shell tools. Try using the Debian based image instead

[rittneje]

@lorenzo In my experience such docker images usually include "distroless" in the tag to make it clear (e.g., hadolint/hadolint:v2.3.0-distroless).

[atalwar-sephora]

@lorenzo Thanks, it works with debian image. I used hadolint/hadolint:latest-debian

[atalwar-sephora]

Use Debian or alpine base image for shell.
