Hansible

TL;DR

Install the latest version of Ansible or run bootstrap.sh if you are on a Debian based distro.
Edit the hosts file to have the hosts you want and modify variables as needed.
Create rings for the cluster.
Run the hummingbird playbook ansible-playbook -i hosts hummingbird.yml to install and configure the latest hummingbird.

Inventory

Each storage node should be listed in the hummingbird group. The service_ip variable is the ip that the non-public services will listen on.

hummingbird group variables

Variable	Description
`storage_devs`	A list of devices used as storage for servers. This can also be overriden at the server level.
`proxy_port`	Port the proxy server will listen on.
`container_port`	Port the container server will listen on.
`account_port`	Port the account server will listen on.
`auth_uri`	Auth URI for keystone

Playbooks

hummingbird.yml

This playbook will install and configure the latest version of hummingbird to all of the nodes in the hummingbird group.

keystone.yml

This playbook will install a dockerized keystone that we use for development and testing.

monitoring.yml

This playbook will install a dockerized prometheus, grafana & alertmanager.

Secrets

ansible-vault encrypt_string <string_to_encrypt> --ask-vault-pass

Will prompt you for a password. It results in:

!vault |
          $ANSIBLE_VAULT;1.1;AES256
          31633734306439336165653439346662323730393765633466353634333133316566373961663739

You can paste this into a yaml inventory file. (Not an INI file.)

hummingbird:
  hosts:
    localhost:
  vars:
    hash_prefix: !vault |
          $ANSIBLE_VAULT;1.1;AES256
          31633734306439336165653439346662323730393765633466353634333133316566373961663739
          6539633735306336373465306336373366653761656666620a653464373461363234346339333431
          37376337396362346266613061383862323636316432353230633136656161313661643939363866
          3838346232316434360a633964643434633763336565386339643764616566383661373663333062
          34316463363061633363623339383864626162323661396262303562656433343233

Then when you execute it, just pass in:

sudo ansible-playbook -i hosts.yml hummingbird.yml --vault-id @prompt

Keys and Certs

Two vars need to be placed in your inventory.

ca_key_content: CA private key pem
ca_cert_content: CA cert pem

It's highly encouraged to encrypt this file:

ansible-vault encrypt group_vars/hummingbird/ca.yml --ask-vault-pass

An example can be found in ansible/examples/ca.yml, which you can use (password: asdf):

mkdir group_vars/hummingbird
cp examples/ca.yml group_vars/hummingbird/
ansible-vault edit group_vars/hummingbird/ca.yml
ansible-vault rekey group_vars/hummingbird/ca.yml --ask-vault-pass

Generating the CA key:

openssl genrsa -out /path/to/key.pem 4096

Generate the self signed CA cert (from the hummingbird dir):

openssl req -config ansible/keys/ca.conf -key /path/to/key.pem -new -x509 -days 3560 -extensions ca_ext -out /path/to/ca.cert.pem -subj "/CN=Hummingbird CA"

Monitoring

Monitoring group variables

Variable	Description
`grafana_admin_user`	Admin user for Grafana UI
`grafana_admin_password`	Encrypted Grafana admin password
`alertmanager_route`	Routes for Alertmanager
`alertmanager_receivers`	Receivers config for alerts
`prometheus_scrape_configs`	This section specifies set of targets and parameters describing how to scrape them

To install monitoring role:

sudo ansible-playbook -i hosts.yml monitoring.yml --vault-id @prompt

Filebeat

This role was yanked from https://github.com/rcbops/rpc-role-filebeat.

It can be minimally configured with two variables:

filebeat_logging_paths:
  - paths:
    - '/var/log/hummingbird/*.log'
filebeat_logstash_hosts:
  - '<logstash_host>'

For an INI inventory, I used a group_vars/hummingbird yml file. If using a yml inventory, you can just put these directly in there.
