Help setting up ES with Ansible/Docker/Vagrant


(heisenberg) #1

I have set up 3 VMs for running elastic search using Vagrant, and ansible
(w/docker)

In my Hosts file:

I added these lines to define the 3 VM's addresses:
192.168.50.10 earth
192.168.50.11 hiveholm
192.168.50.12 moth

This just gives the private address of the VM a name

I use Vagrant to build and map 3 VM's on my Mac:

Vagrantfile:

-- mode: ruby --

vi: set ft=ruby :

ROOT = File.dirname(File.absolute_path(FILE))

Vagrantfile API/syntax version. Don't touch unless you know what you're

doing!
VAGRANTFILE_API_VERSION = '2'

Default env properties which can be overridden

Example overrides:

echo "ENV['PASSENGER_DOCKER_PATH'] ||=

'../../phusion/passenger-docker' " >> ~/.vagrant.d/Vagrantfile

echo "ENV['BASE_BOX_URL'] ||=

'd:/dev/vm/vagrant/boxes/phusion/'" >> ~/.vagrant.d/Vagrantfile
BASE_BOX_URL = ENV['BASE_BOX_URL'] ||
'https://oss-binaries.phusionpassenger.com/vagrant/boxes/'
VAGRANT_BOX_URL = ENV['VAGRANT_BOX_URL'] || BASE_BOX_URL +
'ubuntu-12.04.3-amd64-vbox.box'
VMWARE_BOX_URL = ENV['VMWARE_BOX_URL'] || BASE_BOX_URL +
'ubuntu-12.04.3-amd64-vmwarefusion.box'
BASEIMAGE_PATH = ENV['BASEIMAGE_PATH' ] || '.'
PASSENGER1_DOCKER_PATH = ENV['PASSENGER1_PATH' ] || '../vm1'
PASSENGER2_DOCKER_PATH = ENV['PASSENGER2_PATH' ] || '../vm2'
PASSENGER3_DOCKER_PATH = ENV['PASSENGER3_PATH' ] || '../vm3'

DOCKERIZER_PATH = ENV['DOCKERIZER_PATH'] || '../dockerizer'

This builds and runs 3 VM's in a private network, using the phusion
baseimage-docker base:
I then run anansible playbook to setup the VM's so they have their own sash
ansible-playbook (terra1.yml)

  • name: terra
    hosts: all

user: $user

remote_user: root
sudo: yes

gather_facts: yes
tasks:
- name: install pip
shell: apt-get -y install python-pip

- name: install docker-py
  pip: name=docker-py state=present


- name: Do the docker build
  shell: cd /vagrant/image && docker build -t traintracks_image_9 .


- name: Run the container
  docker: ports=45678:22,54328:54328,9200:9200,9201:9201,9202:9202,9300:

9300,9301:9301,9302:9302
name=test_traintracks_image_9g image=traintracks_image_9

Run using this command:

ansible-playbook terra1.yml -i hosts.ini -user=root --ask-pass -vvvv

this installs a couple of things and builds the base image inside the
container with the build step and then runs it.
(Note this is applied to all 3 VMs but in this testing I am just building
out the first vm (earth))

Last step install and setup and run ElastciSearch:

I have reused the "the-ansibles" project playbook as a base for out
playbook to setup and run elastic search
Project is called traintracks
ansible-playbook: terra_es1.yml:

file: terra_es1.yml

  • name: terra
    hosts: all

    remote_user: root
    sudo: yes

    gather_facts: yes

    vars_files:

    • host_vars/earth

    roles:

    • role: auth
      tags: step Begin
    • role: common
      tags: step Common
    • role: security
      tags: Step Security
    • role: ssl
      tags: step SSL
    • role: monit
      tags: step MONIT
    • role: python
      tags: step PYTHON
    • role: jdk
      tags: step JDK
    • role: elasticsearch
      tags: step ElasticSearch

Run with this command:

ansible-playbook terra_es1.yml -i terra1.ini -user=root -vvvv

installs and sets up all the required packages and finally installs elastic
search

All these installation steps seem to SUCCEED or more correctly show no
errors and we basically have not changed anything.
But when you go into the docker container
(ssh root@earth -p 45678)
and look at the supervisord log and the elasticsearch log it shows this
problem it shows this error:

I run netstat andit shows nothing is using the 9300 port but ES fails to
bind it!

This seems to indicate that nothing is using port 9300
but I run the elastic search command from the command line inside the
docker Container:

So I killed supervisord and ran the elasticsearch command from the ssh shell

/usr/local/etc/elasticsearch/bin/elasticsearch -f

I GET THIS:

But I dont get more information

Any help would be appreciated!
