Add hadolint

[rarkins]

https://github.com/lukasmartinelli/hadolint

Requires Haskell

[kayoub5]

we could compile it in a separate container, then move it to the lint-condo container
see #412

[jahluwalia]

Any update on this?

[rarkins]

@jahluwalia please try singapore/lint-condo:latest and see if it works as you expect

[jahluwalia]

@rarkins

This is what was added to lint-condo.yaml

- hadolint ./dev/Dockerfile 

And this is what the result was:

Running "hadolint ./dev/Dockerfile"
/bin/sh: hadolint: not found 

Thanks,
