Couchbase AWS Module

This repo contains a Module for deploying Couchbase on AWS using Terraform and Packer. Couchbase is a distributed NoSQL document database. This module supports running Couchbase as a single cluster:

Couchbase single-cluster architecture

Or as multiple clusters for the various Couchbase services (data, management, search, index, query) and Sync Gateway:

Couchbase multi-cluster architecture

Quick start

If you want to quickly spin up a Couchbase cluster, you can run the simple example that is in the root of this repo. Check out couchbase-cluster-simple example documentation for instructions.

What's in this repo

This repo has the following folder structure:

  • root: The root folder contains an example of how to deploy Couchbase as a single-cluster. See couchbase-cluster-simple for the documentation.
  • modules: This folder contains the main implementation code for this Module, broken down into multiple standalone submodules.
  • examples: This folder contains examples of how to use the submodules.
  • test: Automated tests for the submodules and examples.

How to use this repo

The general idea is to:

  1. Use the scripts in the install-couchbase-server and install-sync-gateway modules to create an AMI with Couchbase and Sync Gateway installed.

  2. Deploy the AMI across one or more Auto Scaling Groups (ASG) using the couchbase-cluster module.

  3. Configure each server in the ASGs to execute the run-couchbase-server and/or run-sync-gateway script during boot.

  4. (Optional): Deploy a load balancer in front of the ASGs using the load-balancer module.

See the examples folder for working sample code.

What's a Module?

A Module is a canonical, reusable, best-practices definition for how to run a single piece of infrastructure, such as a database or server cluster. Each Module is written using a combination of Terraform and scripts (mostly bash) and include automated tests, documentation, and examples. It is maintained both by the open source community and companies that provide commercial support.

Instead of figuring out the details of how to run a piece of infrastructure from scratch, you can reuse existing code that has been proven in production. And instead of maintaining all that infrastructure code yourself, you can leverage the work of the Module community to pick up infrastructure improvements through a version number bump.

Who maintains this Module?

This Module is maintained by Gruntwork. If you're looking for help or commercial support, send an email to modules@gruntwork.io. Gruntwork can help with:

  • Setup, customization, and support for this Module.
  • Modules for other types of infrastructure, such as VPCs, Docker clusters, databases, and continuous integration.
  • Modules that meet compliance requirements, such as HIPAA.
  • Consulting & Training on AWS, Terraform, and DevOps.

How do I contribute to this Module?

Contributions are very welcome! Check out the Contribution Guidelines for instructions.

How is this Module versioned?

This Module follows the principles of Semantic Versioning. You can find each new release, along with the changelog, in the Releases Page.

During initial development, the major version will be 0 (e.g., 0.x.y), which indicates the code does not yet have a stable API. Once we hit 1.0.0, we will make every effort to maintain a backwards compatible API and use the MAJOR, MINOR, and PATCH versions on each release to indicate any incompatibilities.
