Can't install hadolint on Ubuntu with WSL 2

I'm trying to install hadolint to use with docker on a Ubuntu app for Windows with WSL.

Heres how I installed:

wget -O /bin/hadolint https://github.com/hadolint/hadolint/releases/download/v1.16.3/hadolint-Linux-x86_64

and when I ran (on a directory with an Dockerfile):

sudo make lint Dockerfile

and here's the error I'm getting:

# See local hadolint install instructions:   https://github.com/hadolint/hadolint
# This is linter for Dockerfiles
hadolint Dockerfile
make: execvp: hadolint: Permission denied
Makefile:24: recipe for target 'lint' failed
make: *** [lint] Error 127enter code here

I new at Linux and I don't know if there's enough information to help me solve this.

Here's some link's I've looked up.

If you want to use the local binary, all you need to do is to grant it the execution permission:

chmod +x /bin/hadolint

Hence you are in the Docker business anyway, you can alternatively use a hadolint container to get the job done:

docker run --rm -i hadolint/hadolint < Dockerfile

where Dockerfile is the file you want to lint.
