Compute Resources

The compute category provides commands for managing compute resources in Aruba Cloud, including cloud servers and SSH key pairs.

Available Resources​

Cloud Servers​

Cloud servers are virtual machine instances that run your applications and workloads.

Quick Commands:

# List all cloud servers
acloud compute cloudserver list

# Get cloud server details
acloud compute cloudserver get <server-id>

# Create a cloud server
acloud compute cloudserver create --name "my-server" --region "ITBG-Bergamo" --flavor "small" --image <image-id>

# Update a cloud server
acloud compute cloudserver update <server-id> --name "new-name"

# Delete a cloud server
acloud compute cloudserver delete <server-id>

Key Pairs​

SSH key pairs for secure authentication to cloud servers.

Quick Commands:

# List all key pairs
acloud compute keypair list

# Get key pair details
acloud compute keypair get <keypair-name>

# Create a key pair
acloud compute keypair create --name "my-keypair" --public-key "ssh-rsa AAAAB3..."

# Update a key pair (change public key)
acloud compute keypair update <keypair-name> --public-key "ssh-rsa AAAAB3..."

# Delete a key pair
acloud compute keypair delete <keypair-name>

Common Use Cases​

Launching a Cloud Server​

  1. Create a key pair (if you don't have one):

    acloud compute keypair create --name "my-keypair" --public-key "$(cat ~/.ssh/id_rsa.pub)"

  2. List available flavors and images:

    # Check available resources (you may need to use the web console or API)

  3. Create the cloud server:

    acloud compute cloudserver create \
      --name "web-server" \
      --region "ITBG-Bergamo" \
      --flavor "small" \
      --image "your-image-id" \
      --keypair "my-keypair" \
      --tags "production,web"

  4. Verify the server:

    acloud compute cloudserver list
    acloud compute cloudserver get <server-id>

Managing SSH Access​

  1. List all key pairs:

    acloud compute keypair list

  2. Update a key pair (rotate keys):

    acloud compute keypair update "my-keypair" --public-key "$(cat ~/.ssh/id_rsa_new.pub)"

  3. Delete unused key pairs:

    acloud compute keypair delete "old-keypair" --yes

Best Practices​

  • Key Pairs:

    • Use descriptive names for key pairs (e.g., user-john-laptop, ci-cd-server)
    • Rotate keys regularly for security
    • Keep private keys secure and never share them
    • Use different key pairs for different environments

  • Cloud Servers:

    • Use tags to organize servers by environment, project, or purpose
    • Choose appropriate flavors based on workload requirements
    • Monitor server status before performing updates
    • Use key pairs instead of password authentication for better security
