# Deploying Applications
|
||||
|
||||
Once you have your personal cloud infrastructure up and running, you'll want to start deploying applications. This guide explains how to deploy and manage applications on your infrastructure.
|
||||
|
||||
## Application Charts
|
||||
|
||||
The `/charts` directory contains curated Helm charts for common applications that are ready to deploy on your personal cloud.
|
||||
|
||||
### Available Charts
|
||||
|
||||
| Chart | Description | Internal/Public |
|
||||
|-------|-------------|----------------|
|
||||
| mariadb | MariaDB database for applications | Internal |
|
||||
| postgres | PostgreSQL database for applications | Internal |
|
||||
|
||||
### Installing Charts
|
||||
|
||||
Use the `bin/helm-install` script to easily deploy charts with the right configuration:
|
||||
|
||||
```bash
|
||||
# Install PostgreSQL
|
||||
./bin/helm-install postgres
|
||||
|
||||
# Install MariaDB
|
||||
./bin/helm-install mariadb
|
||||
```
|
||||
|
||||
The script automatically:
|
||||
- Uses values from your environment variables
|
||||
- Creates the necessary namespace
|
||||
- Configures storage and networking
|
||||
- Sets up appropriate secrets
|
||||
|
||||
### Customizing Chart Values
|
||||
|
||||
Each chart can be customized by:
|
||||
|
||||
1. Editing environment variables in your `.env` file
|
||||
2. Creating a custom values file:
|
||||
|
||||
```bash
|
||||
# Create a custom values file
|
||||
cp charts/postgres/values.yaml my-postgres-values.yaml
|
||||
nano my-postgres-values.yaml
|
||||
|
||||
# Install with custom values
|
||||
./bin/helm-install postgres --values my-postgres-values.yaml
|
||||
```
|
||||
|
||||
### Creating Your Own Charts
|
||||
|
||||
You can add your own applications to the charts directory:
|
||||
|
||||
1. Create a new directory: `mkdir -p charts/my-application`
|
||||
2. Add the necessary templates and values
|
||||
3. Document any required environment variables
|
||||
|
||||
## Deploying Custom Services
|
||||
|
||||
For simpler applications or services without existing charts, use the `deploy-service` script to quickly deploy from templates.
|
||||
|
||||
### Service Types
|
||||
|
||||
The system supports four types of services:
|
||||
|
||||
1. **Public** - Accessible from the internet
|
||||
2. **Internal** - Only accessible within your local network
|
||||
3. **Database** - Internal database services
|
||||
4. **Microservice** - Services that are only accessible by other services
|
||||
|
||||
### Deployment Examples
|
||||
|
||||
```bash
|
||||
# Deploy a public blog using Ghost
|
||||
./bin/deploy-service --type public --name blog --image ghost:4.12 --port 2368
|
||||
|
||||
# Deploy an internal admin dashboard
|
||||
./bin/deploy-service --type internal --name admin --image my-admin:v1 --port 8080
|
||||
|
||||
# Deploy a database service
|
||||
./bin/deploy-service --type database --name postgres --image postgres:15 --port 5432
|
||||
|
||||
# Deploy a microservice
|
||||
./bin/deploy-service --type microservice --name auth --image auth-service:v1 --port 9000
|
||||
```
|
||||
|
||||
### Service Structure
|
||||
|
||||
When you deploy a service, a directory is created at `services/[service-name]/` containing:
|
||||
|
||||
- `service.yaml` - The Kubernetes manifest for your service
|
||||
|
||||
You can modify this file directly and reapply it with `kubectl apply -f services/[service-name]/service.yaml` to update your service.
|
||||
|
||||
## Accessing Services
|
||||
|
||||
Services are automatically configured with proper URLs and TLS certificates.
|
||||
|
||||
### URL Patterns
|
||||
|
||||
- **Public services**: `https://[service-name].[domain]`
|
||||
- **Internal services**: `https://[service-name].internal.[domain]`
|
||||
- **Microservices**: `https://[service-name].svc.[domain]`
|
||||
- **Databases**: `[service-name].[namespace].svc.cluster.local:[port]`
|
||||
|
||||
### Dashboard Access
|
||||
|
||||
Access the Kubernetes Dashboard at `https://dashboard.internal.[domain]`:
|
||||
|
||||
```bash
|
||||
# Get the dashboard token
|
||||
./bin/dashboard-token
|
||||
```
|
||||
|
||||
### Service Management
|
||||
|
||||
Monitor your running services with:
|
||||
|
||||
```bash
|
||||
# List all services
|
||||
kubectl get services -A
|
||||
|
||||
# View detailed information about a service
|
||||
kubectl describe service [service-name] -n [namespace]
|
||||
|
||||
# Check pods for a service
|
||||
kubectl get pods -n [namespace] -l app=[service-name]
|
||||
|
||||
# View logs for a service
|
||||
kubectl logs -n [namespace] -l app=[service-name]
|
||||
```
|
||||
|
||||
## Advanced Configuration
|
||||
|
||||
### Scaling Services
|
||||
|
||||
Scale your services by editing the deployment:
|
||||
|
||||
```bash
|
||||
kubectl scale deployment [service-name] --replicas=3 -n [namespace]
|
||||
```
|
||||
|
||||
### Adding Environment Variables
|
||||
|
||||
Add environment variables to your service by editing the service YAML file and adding entries to the `env` section:
|
||||
|
||||
```yaml
|
||||
env:
|
||||
- name: DATABASE_URL
|
||||
value: "postgres://user:password@postgres:5432/db"
|
||||
```
|
||||
|
||||
### Persistent Storage
|
||||
|
||||
For services that need persistent storage, add a PersistentVolumeClaim to your service YAML.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If a service isn't working correctly:
|
||||
|
||||
1. Check pod status: `kubectl get pods -n [namespace]`
|
||||
2. View logs: `kubectl logs [pod-name] -n [namespace]`
|
||||
3. Describe the pod: `kubectl describe pod [pod-name] -n [namespace]`
|
||||
4. Verify the service: `kubectl get svc [service-name] -n [namespace]`
|
||||
5. Check the ingress: `kubectl get ingress [service-name] -n [namespace]`
