CouchDB

CouchDB is a NoSQL database that uses JSON for documents. This Ansible role is designed to install and configure CouchDB for using the official CouchDB Docker image via the ansible-role-couchdb.

Warning: This role will not delete or modify existing databases or users. It will only create new databases and users if they do not already exist.

Features

• Sets up CouchDB in a Docker container.
• Creates necessary system tables, if `couchdb_config_single_node: true.
• Adds users as specified in the playbook.
• Sets database permissions.
• Integrates with the MASH playbook for easy deployment.

Usage

To use this role with the MASH playbook, add following lines to your inventory file of your MASH playbook:

You can customize the behavior of the role by setting the following variables in your playbook:

• couchdb_environment_variables_extension: to add additional environment variables to the CouchDB container.
• couchdb_config_extension: to add additional configuration to the CouchDB configuration
• couchdb_config_peruser_enabled: to enable per-user configuration in CouchDB | default is true.
• couchdb_config_require_valid_user_except_for_up: to require a valid user for all requests except for the _up endpoint | default is true.
• couchdb_container_additional_networks_custom: to add additional networks to the CouchDB container.
• couchdb_version: to specify the version of the CouchDB Docker image to use

For more information on possible configuration, refer to the comments in the defaults/main.yml file.

By default, this role will not expose the CouchDB port to the host machine. If you want to access CouchDB from outside the Docker container, you will need to expose the port in your playbook via the couchdb_container_http_host_bind_port variable. Or you can just add the container to another docker network via the couchdb_container_additional_networks_custom variable. Please consider the use of a reverse proxy for secure access to CouchDB.
