# Metabase Deployment
|
||||
|
||||
## Overview
|
||||
This directory contains Kubernetes manifests for deploying Metabase, a business intelligence and analytics platform, along with its PostgreSQL database.
|
||||
|
||||
## Components
|
||||
|
||||
### 1. metabase-postgres.yaml
|
||||
PostgreSQL database deployment:
|
||||
- Persistent storage for data
|
||||
- ConfigMap for database configuration
|
||||
- Secret for database password
|
||||
- Service for internal communication
|
||||
|
||||
### 2. metabase-deployment.yaml
|
||||
Metabase application deployment:
|
||||
- Metabase container with latest image
|
||||
- Persistent storage for application data
|
||||
- Environment variables for database connection
|
||||
- Health checks and resource limits
|
||||
- Service for internal communication
|
||||
|
||||
### 3. metabase-ingress.yaml
|
||||
Ingress configuration for external access:
|
||||
- Nginx ingress class
|
||||
- Multiple host support (metabase.freeleaps.cluster, metabase.local)
|
||||
- SSL redirect disabled for development
|
||||
|
||||
## Deployment Steps
|
||||
|
||||
### 1. Deploy PostgreSQL Database
|
||||
```bash
|
||||
kubectl apply -f metabase-postgres.yaml
|
||||
```
|
||||
|
||||
### 2. Wait for PostgreSQL to be Ready
|
||||
```bash
|
||||
kubectl wait --for=condition=ready pod -l app=metabase-postgres -n metabase --timeout=300s
|
||||
```
|
||||
|
||||
### 3. Deploy Metabase Application
|
||||
```bash
|
||||
kubectl apply -f metabase-deployment.yaml
|
||||
```
|
||||
|
||||
### 4. Deploy Ingress (Optional)
|
||||
```bash
|
||||
kubectl apply -f metabase-ingress.yaml
|
||||
```
|
||||
|
||||
### 5. Monitor Deployment
|
||||
```bash
|
||||
kubectl get pods -n metabase
|
||||
kubectl get services -n metabase
|
||||
kubectl get ingress -n metabase
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Database Connection
|
||||
- **Type**: PostgreSQL
|
||||
- **Host**: metabase-postgres
|
||||
- **Port**: 5432
|
||||
- **Database**: metabase
|
||||
- **User**: metabase
|
||||
- **Password**: metabasepassword
|
||||
|
||||
### Storage
|
||||
- **Metabase Data**: 10Gi persistent storage
|
||||
- **PostgreSQL Data**: 5Gi persistent storage
|
||||
- **Storage Class**: azure-disk-std-ssd-lrs
|
||||
|
||||
### Resources
|
||||
- **Metabase**: 512Mi-1Gi memory, 250m-500m CPU
|
||||
- **PostgreSQL**: 256Mi-512Mi memory, 250m-500m CPU
|
||||
|
||||
## Access
|
||||
|
||||
### Internal Access
|
||||
- **Metabase**: http://metabase.metabase.svc.cluster.local:3000
|
||||
- **PostgreSQL**: metabase-postgres.metabase.svc.cluster.local:5432
|
||||
|
||||
### External Access (with Ingress)
|
||||
- **Primary**: http://metabase.freeleaps.cluster
|
||||
- **Alternative**: http://metabase.local
|
||||
|
||||
## Initial Setup
|
||||
|
||||
1. **First Access**: Navigate to the Metabase URL
|
||||
2. **Setup Wizard**: Follow the initial setup wizard
|
||||
3. **Database Connection**: Use the internal PostgreSQL connection
|
||||
4. **Admin User**: Create the first admin user
|
||||
5. **Data Sources**: Connect to your data sources
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Check Pod Status
|
||||
```bash
|
||||
kubectl get pods -n metabase
|
||||
kubectl describe pod <pod-name> -n metabase
|
||||
```
|
||||
|
||||
### Check Logs
|
||||
```bash
|
||||
kubectl logs <pod-name> -n metabase
|
||||
kubectl logs <pod-name> -n metabase -c postgres # for PostgreSQL
|
||||
```
|
||||
|
||||
### Check Services
|
||||
```bash
|
||||
kubectl get services -n metabase
|
||||
kubectl describe service metabase -n metabase
|
||||
```
|
||||
|
||||
### Check Storage
|
||||
```bash
|
||||
kubectl get pvc -n metabase
|
||||
kubectl describe pvc metabase-data -n metabase
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
- **Initial Startup**: Metabase may take 2-3 minutes to start up on first deployment
|
||||
- **Database**: Ensure PostgreSQL is fully ready before deploying Metabase
|
||||
- **Storage**: Both Metabase and PostgreSQL use persistent storage for data persistence
|
||||
- **Security**: Default password is base64 encoded, consider changing for production use
