The most common pro is "Build once deploy everywhere" even is possible, I always feel pushing a 500 MB tar image to the production servers is more an annoyance than being helpful; Yes, You can setup your own registry but maintaining the service, securing, adding user permissions and maybe use a proper backend like S3 is an extra annoying layer and another component that could fail.

If the docker tool will have something like `docker serve` and start his own local registry will be more than great.

For this case when I switch to Go was a great solution, building the binary is everything you need.

About docker being helpful for development, definitively yes, I switch to postgres, elasticsearch and redis containers instead of installing them on my computer, is easy to flush and restart and having different versions of services is also more manageable
