Chinchilla

A service which connects to Rabbitmq queues and delivers messages to REST endpoints.

Chinchilla can be configured either with a yaml config, or with consul. In either case, the config backend is watched for changes and will live-update your running chinchilla daemon to reflect the new configuration.

Configure

docker run -d \
	-e "CONSUL_HTTP_ADDR=consul.foo.com:8500" \
	-e "VAULT_SERVICENAME=vault" \
	-e "VAULT_APPROLE_PATH=s3://bucket-name/chinchilla-role-id" \
	-e "VAULT_APPROLE_SECRET_ID=${VAULT_APPROLE_SECRETID}" \
	-e "AWS_ACCESS_KEY_ID=******" \
	-e "AWS_SECRET_ACCESS_KEY=******" \
	-e "AWS_DEFAULT_REGION=us-east-1" \
	-e RABBITMQ_USER=guest \
	-e RABBITMQ_SERVICENAME=rabbitmq \
	benschw/chinchilla

testing

Install and configure Rabbitmq

sudo aptitude

# allow guest login other than loopback (for consul discovery)
cat << EOF > /etc/rabbitmq/rabbitmq.config
[{rabbit,[
	{loopback_users, []}
]}].
EOF

Install and configure Consul

# get the consul binary
wget https://dl.bintray.com/mitchellh/consul/0.5.2_linux_amd64.zip
unzip 0.5.2_linux_amd64.zip

# get the web ui and drop it in your /tmp dir
wget https://dl.bintray.com/mitchellh/consul/0.5.2_web_ui.zip
unzip 0.5.2_web_ui.zip
mv dist /tmp/web-ui


# run wrapper script that will configure some demo info
./consul.sh

Encrypt Rabbit Credentials in your Config

see [https://github.com/xordataexchange/crypt] for details

Update app.batch with your info, and run the following to generate your keys:

gpg2 --batch --armor --gen-key app.batch

This will generate .pubring.gpg and .secring.gpg for encrypting and decrypting rabbitmq credentials in your configuration backend.

app.batch
