An Ansible Playbook for deploying Meteorapps



* Requirement: Ansible > 2.0.0



This Ansible playbook will allow you to deploy Meteor apps of all sizes to your own servers/VMs.

It handles setups of varying complexity. From a single small VM that serves your app to a load balanced

setup with multiple servers.



# Features:

- Deploying multiple apps to a single server

- Setup and configure a MongoDB server with authentification and oplog enabled

- Scale vertically by spawning multiple processes of your app.

  Passenger will handle loadbalancing requests across those processes

- Scale horizontally across multiple servers with HaProxy

- Configure SSL support either for a single node or HaProxy



## Inventory:

This playbook covers three types of groups in your inventory:

- appservers

- mongoservers

- loadbalancers



For a minimal setup (with hosted MongoDB servers with a service like compose)

you only need to provide a single IP in the appservers section



SSH Agent forwarding:

This playbook instructs ansible to forward your ssh agent, which means that

git and mrt will have access to the same repositories that your ssh key has.

Note: you need to run ssh-add -k on OSX once per sessions to add your keys

to the ssh agent



## Tests:

To run tests run run_tests.sh 

Three Tests are included and also serve as examples:

- single_node: Launch a MongoDB server and a appserver with an instance of Telescope

- two_node_multisite:

  Launch a dedicated MongoDB server, and configure passenger on one to serve both Spacetalk (with SSL) and Telescope from the same server

  Note: you can use the same pattern to seperate your staging and production environment

- load_balanced_spacetalk: Launch and configure: A MongoDB server, two appservers (with two instances per server) and a loadbalancer for Spacetalk



### Possible group variables (incomplete, todo extend, for now check tests directory):

all.yml

these are the users that will be created in case you choose your own mongodb server

- mongodb_root_user:

    - the root user, which will be created to enable the creation of the other users

    - username

    - password

- mongodb_meteor_user

  - the user and database which will have access to the database that will be used by meteor

  - username

  - password

  - database

- mongodb_oplog_user

  - username

  - password

- app_bundle_dir: path to where app will be bundled

- app_git_checkout: branch, tag or commit to build

- app_git_repo: ssh path to repo

- app_mobile_server: meteor mobile server param

- app_root_dir: path where git repo will be cloned to

- git_deploy_private_key: git key to use to checkout repo

- meteor_env:

    - HTTP_FORWARDED_COUNT: 1

    - MAIL_URL: ""

    - MONGO_OPLOG_URL: ""

    - MONGO_URL: ""

    - ROOT_URL: ""

    - AUTOUPDATE_VERSION: optional

    - OTHER_ENV_VAR: ""

- meteor_settings_file: path to settings relative to app_root_dir

- nginx_config_file_name: name of the created nginx config file

- nginx_enable_ssl: true

- nginx_server_name: "example.com"

- nginx_force_ssl: false

- nginx_ssl_cert_file_name

- nginx_ssl_key_file_name

- passenger_friendly_error_pages: "off"

- passenger_group: www

- passenger_user: www

- passenger_min_instances: number of app instances on one machine

- passenger_port: 80

- passenger_pre_start: "yes"

- ssl_certificate: if you want to enable ssl eithe on the loadbalancer or on the appserver level, you need to paste your certificates here, use pipe ( | ) for multiline strings (http://stackoverflow.com/a/21699210/404799)

- ssl_key

- app_git_relative_dir: path to app if it resides in a subdirectory of a git repo



Loadbalancer:

- haproxy_config_use_appservers_eth: eth0

- haproxy_enable_ssl: true

- haproxy_enable_stats: true

- haproxy_force_ssl: false

- haproxy_stats_password

- haproxy_stats_port

- haproxy_stats_username

- haproxy_ws_healthcheck_domain: example.com



Appservers:

see roles/meteorapp/README.md



All variables can be combined into all.yml for simpler deployment



Tips:

This article is very good: http://hakunin.com/six-ansible-practices



Todo:

- client_max_body_size



Notes:

ssh agent forwarding is slow when cloning a repo, disable and use git key for faster deploy
