Fission: Ruby Environment
This is the Ruby environment for Fission.
It's a Docker image containing a Ruby 2.4.1 runtime, along with a dynamic loader. A few common dependencies are included in the Gemfile.
Customizing this image
To add package dependencies, edit Gemfile to add what you need, and rebuild this image (instructions below).
Rebuilding and pushing the image
You'll need access to a Docker registry to push the image: you can sign up for Docker hub at hub.docker.com, or use registries from gcr.io, quay.io, etc. Let's assume you're using a docker hub account called USER. Build and push the image to the the registry:
docker build -t USER/ruby-env . && docker push USER/ruby-env
Using the image in fission
You can add this customized image to fission with "fission env create":
fission env create --name ruby --image USER/ruby-env
Or, if you already have an environment, you can update its image:
fission env update --name ruby --image USER/ruby-env
After this, fission functions that have the env parameter set to the same environment name as this command will use this environment.
