Permalink 4 minute read Modified: (Rohan Verma)

If your CGO development toolchain depends on external dependencies such as system libraries, or you want to develop on an older version of go while having a different version on your host, you can use a docker container and mount the source from your host machine and build the project inside the container. This can enable us to have a consistent development environment across various developers and their host systems without having to modify system libraries.
