Ansible-st2

Ansible playbooks to deploy StackStorm.

StackStorm is event-driven automation platform written in Python. With over 50+ integrations like GitHub, Docker, Nagios, NewRelic, AWS, Ansible it allows you to wire together your existing infrastructure into complex Workflows with auto-remediation and many more. Aka IFTTT orchestration for Ops.

Supported platforms

• Ubuntu 14.04

Requirements

At least 2GB of memory and 3.5GB of disk space is required, since StackStorm is shipped with RabbitMQ, PostgreSQL, Mongo, OpenStack Mistral and dozens of Python dependencies.

Installation

ansible-galaxy install -r roles/mistral/requirements.yml

ansible-playbook playbooks/st2express.yaml

Dependencies

Ansible Galaxy roles used by StackStorm installation:

• ANXS.postgresql - PostgreSQL, needed by Mistral

Variables

Below is the list of variables you can redefine in your playbook to customize st2 deployment:

Variable	Default	Description
st2_version	stable	StackStorm version to install. Use latest stable to get automatic updates or pin it to numeric version like 1.4.0.
st2_revision	1	StackStorm revision to install. Used only with pinned st2_version.
st2_system_user	stanley	System user on whose behalf st2 would work, including remote/local action runners.
st2_system_user_in_sudoers	yes	Add st2_system_user to the sudoers (recommended for most st2 features to work).
st2_auth_username	testu	Username used by StackStorm standalone authentication.
st2_auth_password	testp	Password used by StackStorm standalone authentication.
mistral_db	mistral	PostgreSQL DB name for Mistral.
mistral_db_username	mistral	PostgreSQL DB user for Mistral.
mistral_db_password	StackStorm	PostgreSQL DB password for Mistral.

Examples

Install latest stable StackStorm with all its components on local machine:

ansible-playbook playbooks/st2express.yaml -i 'localhost,' --connection=local

Note that keeping stable version is useful to update StackStorm by re-running playbook, since it will reinstall st2 if there is new version available. This is default behavior. If you don't want updates - consider pinning version-revision numbers.

Install specific numeric version of st2 with pinned revision number as well:

ansible-playbook playbooks/st2express.yaml --extra-vars='st2_version=1.4.0 st2_revision=8'
