assimilation-vagrant-cluster

Runs Assimilation in a cluster. Control Vagrant with a YAML file. Start as many boxes as you like. They all run in the same private network (using DHCP, name resolution included).

Caveat no. 1: Works only with the Virtualbox provider.

Caveat no.2: Only used and tested with CentOS 7.

Usage

Edit hosts.yaml according to your needs and run vagrant up.

Format of hosts.yaml

domain: local
boxes:
    # this is the CMA
    - name: &name1 cma
      box: centos-7.1-x86_64 
      hostname: *name1 
      provision:
          - name: 'provision/multicast.sh'
            run: 'always'
          - name: 'provision/update_c7.sh'
          - name: 'provision/cma.sh'
      triggers:
          - "systemctl start neo4j.service ; sleep 10"
          - "systemctl start assimilation-cma.service ; sleep 10"
          - "systemctl start assimilation-nanoprobe.service"
    # This is one "client" running nanoprobe
    - name: &name2 box1
      box: centos-7.1-x86_64 
      hostname: *name2 
      provision:
          - name: 'provision/multicast.sh'
            run: 'always'
          - name: 'provision/update_c7.sh'
          - name: 'provision/nano.sh'
      triggers:
          - "systemctl start assimilation-nanoprobe.service"

• domain is optional. Default is .local.
• CPU and memory are optional. Their default values are 1024MB and 1 CPU.
• box_url is optional.
• provision is an array with paths to scripts which get executed inside the VM. name contains the path to the script. If run is set to "always", the script will always run as described in the Vagrant documentation

Requirements

You must install the Vagrant plugins vagrant-hostmanager and vagrant-triggers. It is recommended to install vagrant-cachier.

Accessing the neo4j webconsole
