Used stack:

• Google Cloud SDK: 245.0.0
• Terrafrom: 0.11.14
• Ansible: 2.8.1
• Packer: 1.4.1
• Bash: 3.2.57
• Gsutil: 4.38

General schema:

This is the DEMO stand such demostrates how the IAC (infrastructure as code) feature can help you with provisioning of the cloud powers in mins. Terraform/Packer/Ansible stack used for creation/provisioning of environment. Automation steps are metioned below:

1. Packer creates custom image "gcp-centos7-apache" which built with provisioner's script **install.sh ** and a direcory with public key, such baked inside the image. The base image is centos-7, ssh user is gcp, apache web-server is installed and enabled on this step. Healthchek point /health is configured by default in "gcp-centos7-apache" image.
2. Terraform creates a cluster of 3 instances, including internal load balancer with health checks. And many other entities (check the list after the "ansible" description part)
3. Ansible used to provision the simple php web-site such helps to observe the load-balancing process. The web site is working in HA mode, one-point access provided by internal load-balancer IP

The full list of GCP resources is placed below:

• google_compute_health_check;
• google_compute_http_health_check;
• google_compute_firewall;
• google_compute_target_pool;
• google_compute_instance_template;
• google_compute_instance_group_manager;
• google_compute_autoscaler;

Usage:

manage.sh is a main entrypoint script. You can charge your cloud deployments with this script changing the input keys. -d- means deploy;

./manage.sh -d

-e means erase;

./manage.sh -e
