Couch Formation 4.0.0a354

Toolset for running and managing Couchbase assets in the cloud.

Disclaimer

This package is NOT SUPPORTED BY COUCHBASE. The toolset is under active development, therefore features and functionality can change.

Prerequisites

• Python 3.8+
• Cloud CLI/SDKs
  • AWS CLI
  • Google Cloud CLI
  • Azure CLI
• Homebrew (for macOS)

Quick Start

Install (pip user local method):

pip3 install --user couchformation

export PATH=$(python3 -m site --user-base)/bin:$PATH

Install (virtual environment method):

python3 -m venv couchformation

cd couchformation

. bin/activate

pip3 install couchformation

Install directly from GitHub repo:

pip3 install --user git+https://github.com/couchbaselabs/couch-formation-core

Basic example

Configure and deploy a Couchbase Server cluster:

cloudmgr create --build cbs --cloud gcp --project test-gcp --name test-cluster --region us-central1 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 4x16

Deploy the project:

cloudmgr deploy --project test-gcp

MDS example

Create the initial service group:

cloudmgr create --build cbs --cloud aws --project dev01 --name testdb01 --region us-east-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

Add a second service group:

cloudmgr add --build cbs --cloud aws --project dev01 --name testdb01 --region us-east-2 --quantity 2 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32 --services analytics

Multiservice project example

Configure a 3 node Couchbase Server cluster in US Ease, another 3 node Couchbase Server cluster in US West, plus a Linux generic node and a Windows generic node to run an application.

cloudmgr create --build cbs --cloud aws --project dev01 --name source01 --region us-east-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

cloudmgr create --build cbs --cloud aws --project dev01 --name target01 --region us-west-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

cloudmgr create --build generic --cloud aws --project dev01 --name app01 --region us-east-2 --quantity 1 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

cloudmgr create --build generic --cloud aws --project dev01 --name app02 --region us-east-2 --quantity 1 --os_id windows --os_version 2022 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

Custom services example

cloudmgr create --build cbs --cloud aws --project eventing --name eventing01 --region us-east-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32 --services data,index,query,eventing

Sync Gateway example

Create the Couchbase Server cluster:

cloudmgr create --build cbs --cloud aws --project sgw-dev01 --name devdb01 --region us-east-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 4x16

Create a Sync Gateway and connect to the cluster:

cloudmgr create --build sgw --cloud aws --project sgw-dev01 --name gateway --region us-east-2 --quantity 1 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 4x16 --connect devdb01

Capella example

For Capella the Couch Formation project aligns with the Capella project.

cloudmgr create --build capella --cloud capella --project test-project --name test-cluster --region us-east-2 --quantity 3 --provider aws --machine_type 4x16

Optionally create an app service (Sync Gateway in Capella) and attach it to a Capella database.

cloudmgr create --build capella --cloud capella --project test-project --name test-app-svc --quantity 2 --machine_type 4x8 --type mobile --connect test-cluster

Additional commands

Destroy a project:

cloudmgr destroy --project dev01

List node details (including IP addresses and generated passwords):

cloudmgr list --project dev01

Operate on only one service in a project:

cloudmgr deploy --project dev01 --name source01

List all projects and services:

cloudmgr list

Display detailed information about configured services in a project:

cloudmgr show --project dev01

Recall the CLI commands that were used to add services to a project (you can use this to copy and paste to create a new project):

cloudmgr cli --project dev01

Change the values for parameters in a previously created service:

cloudmgr update --project dev01 --name node --machine_type 8x32

Change the values for parameters for a service node group:

cloudmgr update --project dev01 --name testdb --group 2 --machine_type 4x16

AWS SSO Support

Setup AWS CLI SSO:

aws configure sso

SSO Integration:

Use the auth_mode option to enable SSO integration. Couch Formation will open a browser for you to complete the SSO process, or you will have to paste the link provided into a browser to continue.

cloudmgr create --build cbs --cloud aws --project dev01 --name testdb01 --auth_mode sso --region us-east-2 --quantity 3 --os_id ubuntu --os_version 22.04 --ssh_key /Users/jdoe/.ssh/jdoe-default-key-pair.pem --machine_type 8x32

AWS Default Authentication

Configure the AWS CLI via an appropriate method based on your IAM settings. For example use aws configure to configure long term credentials, or manually set the access parameters in .aws/credentials or with environment variables. Couch Formation accepts an optional --profile service configuration parameter to use a specific auth profile. Check here for more information.

GCP Default Authentication

For Google Cloud use gcloud auth application-default login to configure CLI access. Check here for more information.

Azure Default Authentication

For Azure use az login to configure CLI access. Check here for more information.

Capella Support

Credentials Directory

The automation for Capella uses the v4 public API. To use the automation, create an API key in the Capella UI and save it to a file named default-api-key-token.txt in a directory named .capella in your home directory.

.capella
├── credentials
├── default-api-key-token.txt
├── project-api-key-token.txt
└── test-api-key-token.txt

Credentials file format:

[default]
api_host = cloudapi.cloud.couchbase.com
token_file = default-api-key-token.txt
account_email = john.doe@example.com

[project]
token_file = project-api-key-token.txt

Windows

Download and install a 64-bit version of Python 3.8+ from here. Use the Run as Administrator option to start PowerShell and then install Couch Formation with pip. Once the installation is complete, it will be available for all users (launch a PowerShell window as your login user to use Couch Formation). You should install the wheel pacakge before you install Couch Formation.

pip3 install wheel

pip3 install couchformation
