Ansible and the Power of Google Cloud Platform Eric Johnson Program Manager, Google Compute Engine 

Cloud Platform Agenda • Why Google? • Whirlwind tour of Google Cloud Platform • Introducing the new Ansible Modules 

For the past 15 years, Google has been building out a massively fast, powerful, and reliable cloud infrastructure across the planet. Images by Connie Zhou 

Cloud Platform Developing our infrastructure while respecting our ecosystem • Pioneering data center efficiency • Financed over 250 Megawatts of new wind power • First data centers to receive IOS 14001 certification • 100% carbon neutral

Cloud Platform Compute Engine Cloud Storage Ansible 

Cloud Platform New Ansible Modules New in Ansible 1.4(*) ● Google Compute Engine ○ gce - Instance (VM) management ○ gce_pd - Manage Persistent Disks ○ gce_net - Networks and Firewall Rules ○ gce_lb - Traffic Load-balancing of Instances ● Google Cloud Storage ○ gc_storage - Manage your Buckets and Objects (*) Depends on unreleased libcloud (0.14.0-beta1 coming soon) 

Cloud Platform Module: gce Instance Management ● Create ○ Blocks until RUNNING ● Destroy ● Specifying instances ○ `name` for single instances ○ `instance_names` for >1 ● With/without PD boot disk Module Parameters: image instance_names machine_type metadata name network persistent_boot_disk state tags zone 

Cloud Platform Inventory Plugin Instance Information ● Supports --host and --list ● Auth credentials in gce.ini ● Does *not* use a local cache --list categorizes instances by ● Zones, Machine Types, Networks, etc --host attributes: gce_description gce_id gce_image gce_machine_type gce_metadata gce_name gce_network gce_private_ip gce_public_ip gce_status gce_tags gce_uuid gce_zone 

Cloud Platform Module: gce_pd Persistent Disk Management ● Unformatted Only ● Create, Destroy ● Attach / Detach ● RW / RO Module Parameters: detach_only instance_name mode name size_gb state zone 

Cloud Platform Module: gce_net Networks and Firewalls ● Create / Destroy Networks ○ Networks are global ○ User defined network ranges ● Create / Destroy FW Rules ○ FW Rules require a network ○ Custom protocol/ports ○ Tags / ranges supported Module Parameters: allowed ipv4_range fwname name src_range src_tags state 

Cloud Platform Module: gce_lb Manage Load-balancing ● Instance / member list ● Protocol / port range ● HTTP HealthChecking Module Parameters: httphealthcheck_name httphealthcheck_port httphealthcheck_path httphealthcheck_interval httphealthcheck_timeout httphealthcheck_unhealthy_count httphealthcheck_healthy_count httphealthcheck_host name protocol region external_ip port_range members state 

Cloud Platform Module: gc_storage Google Cloud Storage ● Manage Buckets / Objects ● Upload / Download Objects ● Interoperable Mode ● Uses ‘boto’ library Module Parameters: bucket dest expiration force gcs_access_key gcs_secret_key mode object permission src 

Cloud Platform Demo Time! Using the new Ansible GCE Modules, let’s build a trivial load-balanced web site ● Spin up two GCE instances ● Install Apache and custom index.html page ● Create a custom Health Check URL ● Create a Load Balancer and open up TCP:80
