2015 Dynamic Clarity
define variables with a JSON web service 1
{ "server_ip": "192.168.0.44", "server_name": "dilbert" } https://api.site.com/config/staging
{ "server_ip": "10.10.11.34", "server_name": "pointy_haired_boss" } https://api.site.com/config/production
multi-stage environments 2
!"" inventory # !"" _common # # $"" inventory #
!"" production # # !"" group_vars # # # $"" all # # !"" host_vars # # $"" inventory -> ../_common/inventory # $"" staging # !"" group_vars # # $"" all # !"" host_vars # $"" inventory -> ../_common/inventory
ansible_connection=local for local connections, use 3
single self-contained repo 4
remove global config (/usr/local/etc/ansible/hosts) keep SSH config in Ansible project
check out repo and run!
cloud-local control host 5
co-located on same VPC / VLAN
~zero latency no public SSH repo access required
buildkite.com* for deployment 6
install agent on Ansible control host
None
use roles 7
don’t use roles, use include
roles can’t strictly be mixed with tasks
pre_tasks: - remove host from load balancer pool roles: -
rails tasks: - do stuff post_tasks: - return load balancer back to pool
pre_tasks: - remove host from load balancer pool tasks: -
do stuff - role: nginx - do more other stuff - role: rails post_tasks: - return load balancer back to pool
roles/ nginx/ files/ templates/ tasks/ handlers/ vars/ defaults/ meta/
$ ansible-galaxy init
Ruby* modules 8
located in /library must be executable task name is file
name
#!/usr/bin/env ruby # WANT_JSON shebang warning!

- name: copy something template: src: "templates/config.j2" dest: "/home/{{ deploy_user
}}/config" owner: "{{ deploy_user }}" group: "{{ deploy_user }}" mode: 0755
- name: copy something template: > src="templates/config.j2" dest="/home/{{ deploy_user }}/config"
owner="{{ deploy_user }}" group="{{ deploy_user }}" mode=0755
multiline for single parameter = good
- name: decrypt the key on the server sudo_user: "{{
deploy_key_user }}" command: > openssl rsa -in {{ deploy_key_path }}.protected -out {{ deploy_key_path }} -passin pass:{{ deploy_key_secret }}
