This repository contains all the necessary files to compile Ruby and package it into a .deb file.

This guide uses an Ubuntu 14.04 (Trusty) Docker image as a base. If you need something else, create a new branch and edit the Dockerfile. Docker ensures we have a clean environment with dependencies that match our production setup.

Using a Custom Ruby Definition

Ruby-Build is a tool that abstracts away some of the pains of manually compiling Ruby. It uses definition files to give instructions on how to build Ruby.

Since we are compiling Ruby to be packaged to a different system instead of the same system, we have to edit the default definition file. More specific, we have to remove the verify_openssl instruction. This instruction currently cannot be used when compiling for a package.

The target Ruby version for this branch is 2.3.8. If you need a different version, you will have to create a new definition file. Use the Ruby-Build template directory to find the desired version and remember to remove the verify_openssl instruction. Also change the version in the Debian control file

Publishing a new Ruby version with jemalloc

After ensuring you have a working installation of Docker and the desired definition file, we will build an Image of the environment necessary to compile Ruby.

Build the Docker Image using this repository as a context and ruby-jemalloc as the image name.

If you are using a branch other than master, check the documentation so you can modify the command below.

Using GitHub SSH:

$ docker build [email protected]:myfreecomm/ruby-jemalloc.git -t ruby-jemalloc

Or using GitHub HTTPS:

$ docker build https://github.com/myfreecomm/ruby-jemalloc.git -t ruby-jemalloc

This may take a while for the first time.

Once the build is complete, run the image with a bash entrypoint:

$ docker run -it ruby-jemalloc bash

Now you are inside the Docker image and ready to compile Ruby.

Run the following command with the desired Ruby version.

$ ./compile_and_build.sh 2.3.8

This will compile Ruby and build the .deb package.

To publish the package to Gemfury, read this documentation.
