build_ruby is a tool for building Ruby packages using Docker. Currently it builds only .deb packages for Ubuntu. The debs that it creates will install Ruby to /opt/ruby<version>, eg /opt/ruby2.1.0 or /opt/ruby1.9.3-p429. This is to allow for multiple concurrent installs (that we symlink into the rbenv dir) and is how we install Ruby at Basecamp. If you need Ruby in another location submit a pull request.

Follow the instructions here

On this page follow these tasks:

• Installing VirtualBox
• Installing boot2docker with Homebrew

Next run:

$ boot2docker init
$ boot2docker up

You will get a message like this:

To connect the docker client to the Docker daemon, please set:
export DOCKER_HOST=tcp:https://192.168.59.104:2376
export DOCKER_CERT_PATH=/Users/will/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1

Run the exports you are given. Now run this command (may take a few minutes):

boot2docker down
for i in {49000..49900}; do
 VBoxManage modifyvm "boot2docker-vm" --natpf1 "tcp-port$i,tcp,,$i,,$i";
 VBoxManage modifyvm "boot2docker-vm" --natpf1 "udp-port$i,udp,,$i,,$i";
done

Now start the boot2docker image:

$ boot2docker start

You can now run docker commands locally on your mac.

If the VM got shut down and you want to run build_ruby first start boot2docker:

boot2docker up

Next, run the exports you are given. Run build_ruby as normal.

$ git clone [email protected]:wjessop/build_ruby.git
$ cd build_ruby
$ make

$ bin/build_ruby -r 2.1.0 -i 37s~precise -d ubuntu:12.04
$ bin/build_ruby -r 2.1.0 -d ubuntu:13.04
$ bin/build_ruby -r 2.1.0

Developing for build_ruby should be fairly straightforward if you have Docker installed. The only complication is if you change any files in data/, then you will need to re-run the go-bindata command, and that needs installing first:

This project requires go-bindata, you will need to install it.

The instructions on the go-bindata github repo don't seem accurate (rr at least I couldn't get them to work as advertised) so if you need to install it follow this procedure:

1. go get github.com/jteeuwen/go-bindata
2. cd to the right dir: cd $GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata
3. Build it: go build

Just run:

make

If you need to update the deps run:

make update_deps

See the Makefile for more functions.

go test

2014/05/08 21:50:45 dial unix /var/run/docker.sock: no such file or directory

Make sure you ran export DOCKER_HOST=tcp:https://localhost:4243 in the terminal you are trying to use docker/build_ruby from

• Test that a package test is actually created, perhaps requiring Docker to be running
• Support Other Linux distros/package types

Here's the most direct way to get your work merged into the project:

1. Fork the project
2. Clone down your fork
3. Create a feature branch
4. Add your feature + tests
5. Document new features in the README
6. Make sure everything still passes by running the tests
7. If necessary, rebase your commits into logical chunks, without errors
8. Push the branch up
9. Send a pull request for your branch

Take a look at the TODO list or known issues for some inspiration if you need it, or email me. If you're going to make a major change ask first to maje sure it's in line with the project goals.
