I see that there is a pact-cli docker image as well, but I'm not sure exactly how to incorporate that into my own dockerfile. My instinct is to do a multi-stage dockerfile, where I pull the pact-cli image just to copy the pact-cli script, but when I try and run

docker run -it --entrypoint bash pactfoundation/pact-cli

to browse around inside the docker container and locate the script, I get an error that says it does not have bash installed, 🤷‍♂️

There is no

--help

argument

Are you running alpine? does your image have bash?

You can extend the dockerfile using

FROM

ideally you would just use it as is, as a CLI tool, rather than incorporating into your Dockerfile, but as said you can use Dockerfiles extend syntax to build from an existing image.
