Google Cloud Platform - Deployment Manager Templates

Repo for Deployment Manager templates shared between projects.

Overview

The main purpose of this repo is to have a centralized template repository that can be added to any GCP Deployment Manager project as a Git submodule.

That removes the need of copying the templates from one project to another and the risk of ending with different versions of the templates in each project.

Templates

Templates are organized by type of resource:

• compute
• container
• iam
• sql
• storage
• projects

The type matches the main resources of the template, as in most cases will deploy more GCP resources required to configure / use the main one.

The Makefile

The Makefile is useful for the actual deployments, not for managing the templates.

It expects the following folder configuration:

❯ tree -L 2 .
.
├── Makefile
├── deployments
│   ├── bigotes-pro
│   ├── rael-base
│   ├── rshared
│   ├── project-id-3
│   └── project-id-N
└── templates
    ├── compute
    ├── container
    ├── iam
    ├── project
    ├── sql
    └── storage

For each project, you can have the deployment .yaml manifest in the root folder or using a similar folder hierarchy with folders per each resource type:

deployments/rshared
└── compute
    ├── bigotes-pro-peering.yaml
    └── network.yaml

1 directory, 2 files

With that setup, the makefile will generate a target to:

1. Create the deployment
2. Update the deployment
3. Preview the deployment

For example, with the following tree:

❯ tree deployments
deployments
├── bigotes-pro
│   └── compute
│       └── rshared-peering.yaml
├── rael-base
│   ├── compute
│   │   ├── bigotes-pro-base-peering.yaml
│   │   └── network.yaml
│   └── projects
│       ├── bigotes-pro-project.yaml
│       └── rshared-project.yaml
└── rshared
    └── compute
        ├── bigotes-pro-peering.yaml
        └── network.yaml

7 directories, 7 files

Will generate the following targets:
