# Deploy

Handles deployment of containerized applications to Kubernetes using

Helm charts and environment-specific value overrides.

## When to Use This Skill

Use when deploying or updating services in staging or production

environments.

## Implementation Steps

### Step 1: Validate

Run `helm lint charts/` to verify the chart is syntactically valid.

Check that all required values are defined:

- `image.repository` and `image.tag`

- `replicaCount`

- `resources.limits`

### Step 2: Build and Push

Build the container image and push to the registry:

```bash

docker build -t $REGISTRY/$APP:$TAG .

docker push $REGISTRY/$APP:$TAG

```

### Step 3: Deploy

Run `helm upgrade --install` with the target namespace:

```bash

helm upgrade --install $APP charts/ \

-f charts/values.yaml \

-f charts/values-$ENV.yaml \

-n $NAMESPACE --wait

```

### Step 4: Verify

Check rollout status and health endpoints:

```bash

kubectl rollout status deployment/$APP -n $NAMESPACE

curl -sf https://$APP.$DOMAIN/health

```
