# Deployment Procedures

> Deployment and rollback procedures for production environments

### Deployment Procedures

#### Environment Strategy

```bash theme={null}
Development → Staging → Production
    ↓           ↓          ↓
 Kustomize   Kustomize   Helm
   (dev)     (staging)  (release)
```

#### Development Deployment

**Trigger**: Automatic on push to `develop` branch (manual gate)

**Method**: Kustomize with dev overlay

```bash theme={null}
make deploy-dev
```

**Configuration**:

* Namespace: `mcp-server-langgraph-dev`
* Auth: `inmemory` (no Keycloak)
* Sessions: `memory` (no Redis)
* Replicas: 1
* Resources: Low limits

#### Staging Deployment

**Trigger**: Manual deployment after dev validation

**Method**: Kustomize with staging overlay

```bash theme={null}
make deploy-staging
```

**Configuration**:

* Namespace: `staging-mcp-server-langgraph`
* Auth: `keycloak`
* Sessions: `redis` (12-hour TTL)
* Replicas: 2
* Resources: Medium limits
* Full observability enabled

#### Production Deployment

**Trigger**: Manual deployment with confirmation

**Method**: Helm chart

```bash theme={null}
make deploy-production
```

**Configuration**:

* Namespace: `mcp-server-langgraph`
* Auth: `keycloak` (SSL verified)
* Sessions: `redis` (SSL enabled, 24-hour TTL)
* Replicas: 3+ (HPA enabled)
* Resources: Production limits
* High availability configured

**Safety Features**:

* 10-second confirmation delay
* Health check validation
* Rolling update strategy
* Pod disruption budgets

### Rollback Procedures

#### Quick Rollback Commands

**Development**:

```bash theme={null}
make deploy-rollback-dev
```

**Staging**:

```bash theme={null}
make deploy-rollback-staging
```

**Production**:

```bash theme={null}
make deploy-rollback-production
```

#### Manual Rollback

**Kubernetes Deployment**:

```bash theme={null}
## List rollout history
kubectl rollout history deployment/mcp-server-langgraph -n mcp-server-langgraph

## Rollback to previous version
kubectl rollout undo deployment/mcp-server-langgraph -n mcp-server-langgraph

## Rollback to specific revision
kubectl rollout undo deployment/mcp-server-langgraph -n mcp-server-langgraph --to-revision=3

## Monitor rollback
kubectl rollout status deployment/mcp-server-langgraph -n mcp-server-langgraph
```

**Helm Rollback**:

```bash theme={null}
## List release history
helm history mcp-server-langgraph -n mcp-server-langgraph

## Rollback to previous release
helm rollback mcp-server-langgraph -n mcp-server-langgraph

## Rollback to specific revision
helm rollback mcp-server-langgraph 2 -n mcp-server-langgraph
```
