Docmost

Deploy Docmost on Kubernetes — an open-source collaborative wiki and documentation platform. Supports bundled or external PostgreSQL and Redis, local PVC or S3 uploads storage, and scheduled pg_dump backups.

appUrl must be set explicitly in production

If docmost.appUrl is empty, Docmost auto-detects the URL from the Ingress host. In production, always set it explicitly (e.g. https://wiki.example.com). An incorrect appUrl causes password reset emails, invite links, and OAuth redirects to reference the wrong address.

Key Features

Collaborative wiki — real-time editing, spaces, pages, and permissions
PostgreSQL + Redis — bundled subcharts or external connections
Auto-bootstrap — unaccent and pg_trgm extensions granted on first start
Storage modes — local PVC (single replica) or S3-compatible (scalable)
pg_dump backup — scheduled CronJob to S3; database-only (uploads separate)
JWT sessions — configurable jwtTokenExpiresIn with auto-generated app secret

Configuration Reference

Core

Parameter	Type	Default	Description
`replicaCount`	integer	`1`	Pod replicas. Safe to increase only with `storage.mode: s3`.
`nameOverride`	string	`""`	Override the chart name.
`fullnameOverride`	string	`""`	Override the full release name.
`commonLabels`	object	`{}`	Extra labels added to all resources.

Image

Parameter	Type	Default	Description
`image.repository`	string	`docker.io/docmost/docmost`	Docmost image.

`image.pullPolicy`	string	`IfNotPresent`	Image pull policy.

Docmost Configuration

Parameter	Type	Default	Description
`docmost.appUrl`	string	`""`	Full public URL. Auto-detected from first Ingress host if empty. Set explicitly in production.
`docmost.appSecret`	string	`""`	Application secret key. Auto-generated if empty. Store in a stable secret for production.
`docmost.jwtTokenExpiresIn`	string	`30d`	JWT token expiration for user sessions.
`docmost.extraEnv`	array	`[]`	Extra environment variables for the container.

Database

Auto-detection precedence (database.mode: auto):

database.external.host or database.external.existingSecret → external PostgreSQL
postgresql.enabled: true → bundled PostgreSQL subchart

Parameter	Type	Default	Description
`database.mode`	string	`auto`	Database mode: `auto`, `external`, or `postgresql`.
`database.external.host`	string	`""`	External PostgreSQL hostname.
`database.external.port`	integer	`5432`	External PostgreSQL port.
`database.external.name`	string	`docmost`	Database name.

`database.external.existingSecret`	string	`""`	Existing secret with the database password.
`database.external.existingSecretPasswordKey`	string	`database-password`	Key for the password in the existing secret.

External PostgreSQL requires manual extension setup

When using an external PostgreSQL, the bundled bootstrap scripts do not run. Before installing Docmost, manually execute on the target database:

GRANT CREATE ON DATABASE docmost TO docmost;
\connect docmost
CREATE EXTENSION IF NOT EXISTS unaccent;
CREATE EXTENSION IF NOT EXISTS pg_trgm;

PostgreSQL Subchart

Parameter	Type	Default	Description
`postgresql.enabled`	boolean	`true`	Deploy the bundled PostgreSQL subchart.
`postgresql.auth.database`	string	`docmost`	Database name.
`postgresql.auth.username`	string	`docmost`	Database username.

`backup.s3.endpoint`	string	`""`	S3-compatible endpoint URL.
`backup.s3.bucket`	string	`""`	Target bucket name.
`backup.s3.existingSecret`	string	`""`	Existing secret with S3 credentials.
