Setup

CouchDB 3.x can be deployed in either a single-node or a clustered setup. This section covers the first-time setup steps required for each of these configuration.

Single Node

A single node cluster is nothing more than a cluster extended to a single node, ie the local one. To configure it, run:

Enable-CouchDBCluster -SingleNode -Authorization "admin:password"

Cluster

Same thing of the single node, but with two or more nodes. By default the nodes are 3.

Enable-CouchDBCluster -Authorization "admin:password"

Nodes

Nodes are the single elements of a cluster. by element we mean a server, local or remote. To verify the active cluster nodes, run:

Get-CouchDBNode -Authorization "admin:password"

Add a node

To manually add a node to the cluster, simply run:

Add-CouchDBNode -BindAddress 127.0.1.1 -Authorization "admin:password"

Remove a node

To manually add a node to the cluster, simply run:

Get-CouchDBNode -Authorization "admin:password"

Remove-CouchDBNode -Node couchdb@127.0.1.1 -Authorization "admin:password"

Configuration

The CouchDB Server Configuration API provide an interface to query and update the various configuration values within a running CouchDB instance.

Get configuration

To get the entire CouchDB server configuration. The structure is organized by different configuration sections, with individual values.

Get-CouchDBConfiguration -Authorization "admin:password"

Modify configuration

To modify configuration, see help of this cmdlet:

Set-CouchDBConfiguration -?
help Set-CouchDBConfiguration
Get-Help Set-CouchDBConfiguration

Modify an element

For example, to change SSL port 6984 with 443:

Set-CouchDBConfiguration -Element ssl -Key port -Value 443 -Authorization "admin:password"

Note

This cmdlet return the old value. To verify the changed value, run: Get-CouchDBConfiguration -Authorization "admin:password" | Select-Object ssl | Format-List
