Usage Examples

Login to Cluster

# Login with token (recommended)
oc_login with server: "https://api.cluster.example.com:6443",
         authMethod: "token",
         token: "sha256~your-token-here"

# Login with username/password
oc_login with server: "https://api.cluster.example.com:6443",
         authMethod: "password",
         username: "developer",
         password: "your-password"

Discover API Resources

# List all available API resources
oc_api_resources

# List resources for specific API group
oc_api_resources with apiGroup: "apps"

# List only namespaced resources
oc_api_resources with namespaced: true

# Explain a resource schema
oc_explain with resource: "deployment"

# Explain specific field
oc_explain with resource: "pod", field: "spec.containers"

Deploy Application

# Deploy Node.js app from GitHub
oc_new_app with gitRepo: "https://github.com/sclorg/nodejs-ex.git"

Scale Application

# Scale deployment to 3 replicas
oc_scale with name: "my-app", replicas: 3

Patch Resource

# Update deployment labels
oc_patch with resourceType: "deployment", name: "my-app",
         patch: '{"metadata":{"labels":{"environment":"production"}}}'

Security

Authentication Security

• Token Authentication: Preferred method for automation and production use

• Password Authentication: Available but token authentication is recommended

• HTTPS Enforcement: All cluster connections must use HTTPS

• URL Validation: Server URLs validated to prevent SSRF attacks

• Private IP Blocking: Prevents connections to internal/metadata services

Operational Security

• RBAC Compliance: Respects OpenShift RBAC permissions

• No Credential Storage: Credentials are not stored or transmitted by the server

• User Permissions: Executes with the same permissions as the authenticated user

• Input Validation: Comprehensive validation of all inputs and parameters

• Secure Defaults: Conservative security settings by default

Best Practices

• Use Service Account Tokens: For automation and CI/CD pipelines

• Regular Token Rotation: Rotate authentication tokens regularly

• TLS Certificate Validation: Always validate TLS certificates in production

• Least Privilege: Use accounts with minimal required permissions

• Session Management: Use oc logout to clear credentials when done
