This project is primarily a buildpack to run a Etcd Server; but also includes an internal asset-buildpack for compiling Etcd source into executables.
Currently the buildpack includes etcd 0.3.0.
Create a new project with a etcd-version
file containing either 0.3.0
:
mkdir -p /tmp/`whoami`-etcd-service
cd /tmp/`whoami`-etcd-service
echo "0.3.0" > etcd-version
Now deploy to your favourite buildpack-supporting PaaS.
For Cloud Foundry:
cf push `whoami`-etcd-service -b https://github.com/drnic/etcd-service-buildpack.git
And later delete with:
cf delete `whoami`-etcd-service
For Heroku:
git init
git add .
git commit -m "v0.3.0 etcd service"
heroku create `whoami`-etcd-service -b https://github.com/drnic/etcd-service-buildpack.git
git push heroku master
And later destroy with:
heroku apps:destroy `whoami`-etcd-service --confirm `whoami`-etcd-service
There are two stages of development:
bin/compile
, bin/detect
, bin/release
)For each new version of Etcd supported, the config/slugs
file is updated with the accessible URL of the pre-compiled version of etcd.
Extend the bin/fetch_assets
script to fetch the new etcd src asset. Then run it to fetch it (and all other etcd versions):
./bin/fetch_assets
Now modify etcd-compiler/bin/compile
for the new version Etcd (in future this will be beautifully automated) in the blobs folder.
To create the pre-compiled slugs:
gem install anvil-cli
anvil build . -b etcd-compiler -p
The last line is the published slug URL.
Now add this into config/slugs
so buildpack users will have access to the pre-compiled version of Etcd.
You can also use anvil
to do some basic development/test of the buildpack itself (the files bin/compile
, bin/detect
, bin/release
).
anvil build testapp -b . -p
...
https://api.anvilworks.org/slugs/93f4b978-6187-4ce4-affa-64ffea110c14.tgz
The last line will be the slug URL. If you download and unpack it, you will see something like:

The etcd-version
file comes from the built-in testapp
used above. Everything else is included from the buildpack. bin/etcd-server
contains the compiled Etcd server.
If you're not in Ubuntu 10.04, the use Vagrant:
vagrant box add lucid64 http://files.vagrantup.com/lucid64.box
vagrant init lucid64
vagrant up
vagrant ssh
Inside vagrant:
mkdir /tmp/app
cd /tmp/app
wget https://api.anvilworks.org/slugs/93f4b978-6187-4ce4-affa-64ffea110c14.tgz
tar xfz 93f4b978-6187-4ce4-affa-64ffea110c14.tgz
cat Procfile
Either run the process with foreman/goreman or try manually:
export PORT=5656
bin/etcd -name etcd-test -addr 0.0.0.0:$PORT -peer-addr 0.0.0.0:7001 -data-dir data -snapshot true
