Installation via brew

[ilyar]

Maybe I have old habits ...

See the installation via brew (The Missing Package Manager for macOS, Linux and Windows 10):

brew tap ilyar/software
brew install whaler

or

brew install ilyar/software/whaler

I quickly read over the code found at https://github.com/ilyar/homebrew-software/blob/69f57ea7cd12eda4ef7d53fc1e4c86f99f5e911a/Formula/whaler.rb It pulls from my main repository and doesn't look malicious.

I haven't had a chance to do this myself, so if anyone wants to use this way go for it.

I'd recommend just using Docker to inspect docker images and mounting it with a read only socket

docker pull pegleg/whaler
docker run -t --rm -v /var/run/docker.sock:/var/run/docker.sock:ro pegleg/whaler -sV=1.36 nginx:latest
