Cluster - spin up Consul + Vault + Nomad + friends

This script installs and configures Consul, Vault and Nomad. It uses Docker to package these services, since this is not supported by Hashicorp.

Quick start

Install and have Docker up and running. Follow the instructions at get.docker.com.

In case you are using a firewall you may need to allow connections to the IP-adress the liquid bundle is running on. For ufw this can be done with sudo ufw allow to 10.66.60.1.

Clone this repository, then:

cd /opt/cluster

sudo apt install -y nohang  # on CentOS, you can use use "yum"
sudo cp ./examples/nohang.conf /etc/nohang/nohang.conf
sudo systemctl enable nohang.service
sudo systemctl start nohang.service

cp examples/cluster.ini .
./bin/docker.sh
docker exec cluster ./cluster.py supervisorctl -- tail -f start

Wait a minute and visit:

• http://10.66.60.1:8500 - Consul
• http://10.66.60.1:4646 - Nomad
• http://10.66.60.1:8200 - Vault

In case of panic or just to stop it, docker stop cluster will make it all go away.

Running a specific version

To run a tagged version (e.g. v0.9.0) of cluster:

git checkout v0.9.0
./bin/docker.sh --image liquidinvestigations/cluster:0.9.0

Running a command inside a task container

Use cluster.py nomad-exec JOB:TASK COMMAND... to execute a command inside a container. stdin and stdout can be used to exchange data. The command uses nomad alloc exec.

Installing node

As a next step you can install node, by following these instructions .
