# Oracle Cloud Deploy Integration

## Overview

Deploy containerized applications to OCI using either OKE (Oracle Kubernetes Engine) or Container Instances. OKE provides full Kubernetes but requires 4x more config than EKS — you need a VCN, subnet, node pool, OCIR registry, and IAM policies before a single pod runs. Container Instances offer a simpler serverless alternative for workloads that don't need Kubernetes orchestration.

**Purpose:** Get containers running on OCI through both the full Kubernetes path (OKE) and the simpler Container Instances path, with working manifests and registry auth.

## Prerequisites

- **OCI tenancy** with an API signing key in `~/.oci/config`
- **Python 3.8+** with `pip install oci` for SDK-based provisioning
- **Docker** installed for building and pushing images
- **kubectl** installed for OKE cluster interaction
- **Compartment OCID** where resources will be created
- **VCN with subnets** — at least one public and one private subnet for OKE

## Instructions

### Step 1: Push Container Image to OCIR

Oracle Cloud Infrastructure Registry (OCIR) is OCI's Docker-compatible registry. Auth uses an OCI auth token, not your API key:

```bash
# Generate an auth token: Console > Profile > Auth Tokens > Generate Token
# Save the token — it's only shown once

# Login to OCIR (format: {region-key}.ocir.io/{namespace})
docker login us-ashburn-1.ocir.io
# Username: {tenancy-namespace}/oracleidentitycloudservice/{email}
# Password: your auth token

# Tag and push
docker tag myapp:latest us-ashburn-1.ocir.io/{namespace}/myapp:latest
docker push us-ashburn-1.ocir.io/{namespace}/myapp:latest
```

### Step 2: Create OKE Cluster via Python SDK

Use the OCI Python SDK to provision an OKE cluster programmatically:

```python
import oci

config = oci.config.from_file("~/.oci/config")
container_engine = oci.container_engine.ContainerEngineClient(config)

# Create cluster
create_cluster_response = container_engine.create_cluster(
    oci.container_engine.models.CreateClusterDetails(
        name="my-oke-cluster",
        compartment_id="ocid1.compartment.oc1..example",
        vcn_id="ocid1.vcn.oc1..example",
        kubernetes_version="v1.28.2",
        options=oci.container_engine.models.ClusterCreateOptions(
            service_lb_subnet_ids=["ocid1.subnet.oc1..example-public"],
            kubernetes_network_config=oci.container_engine.models.KubernetesNetworkConfig(
                pods_cidr="10.244.0.0/16",
                services_cidr="10.96.0.0/16"
            )
        )
    )
)
cluster_id = create_cluster_response.headers["opc-work-request-id"]
print(f"Cluster creation initiated: {cluster_id}")
```

### Step 3: Add a Node Pool

OKE clusters need at least one node pool to schedule workloads:

```python
container_engine.create_node_pool(
    oci.container_engine.models.CreateNodePoolDetails(
        compartment_id="ocid1.compartment.oc1..example",
        cluster_id="ocid1.cluster.oc1..example",
        name="pool-1",
        kubernetes_version="v1.28.2",
        node_shape="VM.Standard.E4.Flex",
        node_shape_config=oci.container_engine.models.CreateNodeShapeConfigDetails(
            ocpus=2.0,
            memory_in_gbs=16.0
        ),
        node_config_details=oci.container_engine.models.CreateNodePoolNodeConfigDetails(
            size=3,
            placement_configs=[
                oci.container_engine.models.NodePoolPlacementConfigDetails(
                    availability_domain="Uocm:US-ASHBURN-AD-1",
                    subnet_id="ocid1.subnet.oc1..example-private"
                )
            ]
        )
    )
)
```

### Step 4: Configure kubectl for OKE

```bash
# Install the OCI CLI and set up kubeconfig
oci ce cluster create-kubeconfig \
  --cluster-id ocid1.cluster.oc1..example \
  --file ~/.kube/config \
  --region us-ashburn-1 \
  --token-version 2.0.0

# Verify connectivity
kubectl get nodes
```

### Step 5: Deploy to OKE

Create a Kubernetes deployment manifest with OCIR image pull secret:

```bash
# Create OCIR pull secret
kubectl create secret docker-registry ocir-secret \
  --docker-server=us-ashburn-1.ocir.io \
  --docker-username='{namespace}/oracleidentitycloudservice/{email}' \
  --docker-password='{auth-token}' \
  --docker-email='{email}'
```

```yaml
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 3
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      imagePullSecrets:
        - name: ocir-secret
      containers:
        - name: myapp
          image: us-ashburn-1.ocir.io/{namespace}/myapp:latest
          ports:
            - containerPort: 8080
          resources:
            requests:
              cpu: "250m"
              memory: "512Mi"
            limits:
              cpu: "500m"
              memory: "1Gi"
---
apiVersion: v1
kind: Service
metadata:
  name: myapp-svc
spec:
  type: LoadBalancer
  selector:
    app: myapp
  ports:
    - port: 80
      targetPort: 8080
```

### Step 6: Container Instances (Simpler Alternative)

For workloads that don't need Kubernetes, Container Instances provide a serverless option:

```python
import oci

config = oci.config.from_file("~/.oci/config")
ci_client = oci.container_instances.ContainerInstanceClient(config)

ci_client.create_container_instance(
    oci.container_instances.models.CreateContainerInstanceDetails(
        compartment_id="ocid1.compartment.oc1..example",
        display_name="myapp-instance",
        availability_domain="Uocm:US-ASHBURN-AD-1",
        shape="CI.Standard.E4.Flex",
        shape_config=oci.container_instances.models.CreateContainerInstanceShapeConfigDetails(
            ocpus=1.0,
            memory_in_gbs=4.0
        ),
        containers=[
            oci.container_instances.models.CreateContainerDetails(
                image_url="us-ashburn-1.ocir.io/{namespace}/myapp:latest",
                display_name="myapp"
            )
        ],
        vnics=[
            oci.container_instances.models.CreateContainerVnicDetails(
                subnet_id="ocid1.subnet.oc1..example"
            )
        ]
    )
)
print("Container Instance created")
```

## Output

Successful completion produces:

- A container image pushed to OCIR with proper authentication
- Either an OKE cluster with node pool, kubeconfig, and running deployment, or a Container Instance running your application
- OCIR pull secret configured in the Kubernetes cluster
- A load-balanced service exposing your application

## Error Handling

| Error | Code | Cause | Solution |
|-------|------|-------|----------|
| NotAuthenticated | 401 | Bad auth token for OCIR or wrong API key | Regenerate auth token in Console > Profile > Auth Tokens |
| NotAuthorizedOrNotFound | 404 | Missing IAM policy for container engine | Add policy: `Allow group Developers to manage cluster-family in compartment X` |
| TooManyRequests | 429 | Rate limited on cluster operations | Wait and retry — OKE control plane ops are rate-limited |
| ImagePullBackOff | N/A | Wrong OCIR secret or image path | Verify `docker-server`, namespace, and image tag in pull secret |
| InternalError | 500 | OCI service issue | Check [OCI Status](https://ocistatus.oraclecloud.com) and retry |
| Node pool stuck CREATING | N/A | Insufficient capacity in AD | Try a different availability domain or shape |

## Examples

**Quick Container Instance deploy with OCI CLI:**

```bash
# List running container instances
oci container-instances container-instance list \
  --compartment-id ocid1.compartment.oc1..example

# Get cluster kubeconfig in one command
oci ce cluster create-kubeconfig \
  --cluster-id ocid1.cluster.oc1..example \
  --file ~/.kube/config \
  --region us-ashburn-1 \
  --token-version 2.0.0 && kubectl get pods
```

**Verify OCIR image exists:**

```python
import oci

config = oci.config.from_file("~/.oci/config")
artifacts = oci.artifacts.ArtifactsClient(config)
images = artifacts.list_container_images(
    compartment_id="ocid1.compartment.oc1..example",
    repository_name="myapp"
).data
for img in images.items:
    print(f"{img.display_name} — {img.time_created}")
```
