Adventure Deploy

DevOps to the max! GridKick scripts using Ansible to build images.

Requirements

• Vagrant >= 1.2.2
• Ruby >= 2.0.0
• Ansible >= 1.4
• Python >= 2.7 (not sure if 3 will work)

SSH interaction between deploy and rails api app

The Rails API application kicks off Ansible playbooks against the customer database hosts. Since Ansible operates via SSH, we've added a gridkickbackup user and group. The Ansible operations are run through this user. The passphrase-less private SSH key is located in roles/api_ansible_keys/files/backup@gridkick.com. WARNING: this must be passphrase-list since we're not injecting the passphrase to the background Ansible playbook runs at the moment.

Setup "local" Environment

Overall, we have 3 local VirtualBox backed servers, api, mongo, redis. Each has a unique Vagrant implemented IP address, which is dynamically set in each's Vagrant file (./Vagrantfiles/api.vagrant.rb) by referencing the VM's seed file (./seeds/api.seed.rb). Giving each VM box an IP enables apps to address each other via IP (EG, the adventure_api mongoid.yml defines the mongo service endpoint via IP and Port).

Now to the nitty girtty setup info.

0. Define GridKick domains in your machine's /etc/hosts file. API and Frontend apps run on same VM box.

   Host Database

   localhost is used to configure the loopback interface

   when the system is booting. Do not change this entry.

   127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost

   gridkick ### NOTCE

   192.168.211.218 local-api.gridkick.com ### <= IP matches seeds/api.seed.rb 192.168.211.218 local.gridkick.com ### <= IP machtes seeds/frontend.seed.rb

1. Bring GridKick components

   vagrant up api redis mongo

2. Run Ansible Playbooks against all infrastructure.

   ansible-playbook -i hosts/local.hosts core.yml redis.yml mongo.yml

3. Deploy the ansible deploy repo to local server

   cap local deploy:setup cap local deploy

Setup Staging/Production Env

1. Add IPs to hosts file with proper groupings (IE, api/frontend/mongo/redis).

   [api] 162.243.106.59

   [frontend] 162.243.106.59

   [core:children] api frontend

   [redis] 162.243.207.54

   [mongo] 192.241.251.141

   [staging:children] api frontend mongo redis

   [change-ubuntu:children] staging

2. Run ubuntu_prep against hosts:

   ansible-playbook
   -i hosts/staging.hosts
   ubuntu_prep.yml

3. Run ansible-playbooks for total env:

   ansible-playbook
   -K
   -i hosts/staging.hosts
   redis.yml
   mongo.yml
   core.yml

Instance Stuff

Setup

• Setup seeds by copying files to the same location and removing .example
• Pick a server to boot, e.g. redis and run vagrant up redis. This will run Ansible
• To rerun ansible, execute bin/redis/ansible
• To ssh into the redis VM, run bin/redis/ssh
• If everything went well, you should be able to connect to the running redis server using bin/redis/connect
• The same goes for other server types such as mysql or postgresql

MySQL

• To run bin/redis/connect you will need the mysql program installed locally.

PostgreSQL

• To run bin/postgresql/connect you will need the psql program installed locally.

Redis

• To run bin/redis/connect you will need the redis-cli program installed locally.
