Built-in Components Configuration

This page applies only if you use Univer built-in components (PostgreSQL, RabbitMQ, MinIO). These credentials only take effect during the first initialization. After deployment, update passwords via each component's official procedure.

Change Default Passwords

Configure these before the first deployment. Existing instances will not change passwords automatically.

Create .env.custom in the install directory, then run:

Bash

bash run.sh

Create values.yaml, then run:

Shell

helm install -n univer --create-namespace \  --set global.istioNamespace="univer" \  --values values.yaml \  univer-stack oci://univer-acr-registry.cn-shenzhen.cr.aliyuncs.com/helm-charts/univer-stackkubectl rollout restart -n univer deployment/collaboration-serverkubectl rollout restart -n univer deployment/universer
