doctl kubernetes options sizes --format json Returns sizes formatted in JSON.
Troubleshooting
Common pitfalls
Error: Could not retrieve sizes - API request failed.
Solution: Check API key and permissions.
Error: Network timeout while fetching sizes.
Solution: Wait and retry the command.
Error: Unauthorized access - API key required.
Solution: Ensure you have valid API key with required access.
