Dockerfile.localdev

##
# This Dockerfile is used to build the uptime-checker binary for local development.
# It is not used for production. We need this because certain error messages
# are Linux specific so we have to run the binary on Linux to get the correct
# error messages.

# HOW TO USE:
# 1. Build the binary: `docker build -f Dockerfile.localdev -t my-uptime-checker`
# 2. Run the container with a mounted volume for src: `docker run -it -v $(pwd)/src:/app/src --entrypoint /bin/sh my-uptime-checker`
# e. in the container you can do `cargo test`, etc. and updating the src directory on your host will reflect in the container,
# so you can test your changes without having to rebuild the container.
