# ArgoCD Deployment
|
|
|
|
This directory contains ArgoCD Application manifests for deploying Peikarband to Kubernetes.
|
|
|
|
## Files
|
|
|
|
- `application.yaml`: Production deployment (main branch → peikarband namespace)
|
|
- `application-staging.yaml`: Staging deployment (develop branch → peikarband-staging namespace)
|
|
|
|
## Prerequisites
|
|
|
|
1. ArgoCD installed in your cluster
|
|
2. Git repository access configured in ArgoCD
|
|
3. Docker registry credentials (if using private registry)
|
|
|
|
## Deployment
|
|
|
|
### 1. Add Git Repository to ArgoCD
|
|
|
|
```bash
|
|
# For HTTPS with token
|
|
argocd repo add https://git.peikarband.ir/ehsan-minadd/peikarband.git \
|
|
--username YOUR_USERNAME \
|
|
--password YOUR_ACCESS_TOKEN
|
|
|
|
# Or using argocd UI: Settings → Repositories → Connect Repo
|
|
```
|
|
|
|
### 2. Deploy Production
|
|
|
|
```bash
|
|
kubectl apply -f argocd/application.yaml
|
|
```
|
|
|
|
### 3. Deploy Staging
|
|
|
|
```bash
|
|
kubectl apply -f argocd/application-staging.yaml
|
|
```
|
|
|
|
## Sync Policy
|
|
|
|
Both applications use **automatic sync** with:
|
|
- **Auto-prune**: Remove resources deleted from Git
|
|
- **Self-heal**: Automatically sync when cluster state differs from Git
|
|
- **Retry logic**: 5 attempts with exponential backoff
|
|
|
|
## Monitoring
|
|
|
|
```bash
|
|
# Check application status
|
|
argocd app get peikarband
|
|
argocd app get peikarband-staging
|
|
|
|
# Watch sync progress
|
|
argocd app sync peikarband --watch
|
|
|
|
# View logs
|
|
argocd app logs peikarband
|
|
```
|
|
|
|
## Manual Sync
|
|
|
|
```bash
|
|
# Force sync
|
|
argocd app sync peikarband --force
|
|
|
|
# Sync with prune
|
|
argocd app sync peikarband --prune
|
|
```
|
|
|
|
## Rollback
|
|
|
|
```bash
|
|
# List history
|
|
argocd app history peikarband
|
|
|
|
# Rollback to specific revision
|
|
argocd app rollback peikarband <REVISION>
|
|
```
|
|
|
|

|
|
|
|
## Environment Variables
|
|
|
|
Override via Helm values:
|
|
|
|
```yaml
|
|
# In values-production.yaml or values-staging.yaml
|
|
env:
|
|
- name: DATABASE_URL
|
|
value: "postgresql://..."
|
|
- name: REDIS_URL
|
|
value: "redis://..."
|
|
```
|
|
|
|
## Secrets Management
|
|
|
|
Secrets should be managed outside Git:
|
|
|
|
```bash
|
|
# Using kubectl
|
|
kubectl create secret generic peikarband-secrets \
|
|
--from-literal=database-password=xxx \
|
|
--namespace=peikarband
|
|
|
|
# Or using Sealed Secrets, External Secrets Operator, etc.
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### Application Out of Sync
|
|
|
|
```bash
|
|
argocd app sync peikarband --force
|
|
```
|
|
|
|
### Image Pull Errors
|
|
|
|
Check registry credentials:
|
|
```bash
|
|
kubectl get secret regcred -n peikarband -o yaml
|
|
```
|
|
|
|
### Health Check Failing
|
|
|
|
View pod logs:
|
|
```bash
|
|
kubectl logs -n peikarband -l app=peikarband --tail=100
|
|
```
|
|
|
|
### Helm Values Override Not Working
|
|
|
|
Verify values file path in Application manifest:
|
|
```bash
|
|
argocd app manifests peikarband | grep valueFiles
|
|
```
|
|
