Setting

1. SSH Public Key Configuration

Overview

Secure instance access using SSH key pair authentication.

Procedure

1. Generate key pair (local terminal):

   ssh-keygen -t ecdsa -b 521 -f ~/.ssh/instance_key

2. Upload public key (instance_key.pub) via management console

3. Connect to instance:

   ssh -i ~/.ssh/instance_key user@instance-ip

Security Requirements

• Set private key permissions to 600

• ECDSA or EdDSA algorithms required

• Rotate keys quarterly

2. API Key Management

Overview

Credentials for programmatic API access.

Key Handling

1. Generate keys via console interface

2. Include in requests:

   x-apikey: YOUR_API_KEY

Security Policy

• Treat as sensitive credentials

• Immediate revocation if exposed

• 90-day rotation mandatory

3. Registry Authentication

Supported Registries

• Docker Hub

• AWS ECR

• GCR

Configuration

1. Provide credentials in format:

   Username: [registry_user]
   Password: [registry_token]
   Endpoint: [registry_url]

2. Select credentials when creating templates

Troubleshooting

• Verify credential permissions for 403 errors

• Include protocol (https://) in server addresses

Best Practices

• Unique SSH keys per environment

• API key segregation by service tier

• Temporary registry tokens preferred
