How to integrate with pre-commit?

[dudicoco]

Hi,

I have an alias for docker="nerdctl" in my bash profile.
When using pre-commit with a docker image hook I get an error:

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

I assume pre-commit is not using the alias, is there a way to make pre-commit use an alias for the docker command?

looks like out of nerdctl scope! but to help you debug this how can we reproduce this error ?

[dudicoco]

@fahedouch to reproduce, create .pre-commit-config.yaml with the following contents:

repos:
- repo: local
  hooks:
  - id: hadolint
    name: Lint Dockerfiles
    language: docker_image
    entry: hadolint/hadolint:v2.10.0
    args:
    - hadolint

Then run the following:

pre-commit install
git add .
pre-commit run -a

@fahedouch regarding your comment:

Looks like out of nerdctl scope!

Why do you think this is out of nerdctl scope? If nerdctl should be a drop-in replacement for docker, this is a scenario which it should know how to cover - software which calls docker commands, which there are many of.
