Advanced Topics and Troubleshooting

Network Configuration

Automatic Network Setup

The CLI can automatically handle the list of things below in case of SSH permission issues:

1. VPC creation/configuration

2. Subnet management

3. Internet gateway attachment

4. Route table configuration

5. Security group rules

6. Firewall settings

SSH Access Management

The CLI manages SSH access by:

1. Creating SSH key pairs

2. Configuring security groups

3. Setting up instance metadata

4. Managing key permissions

5. Handling different OS users

Limitations and Known Issues

Current Limitations

1. Single region deployment per configuration

2. No direct support for:

   • Multi-cloud deployments

   • Azure resources

   • Custom VPC peering

   • Advanced networking features

3. No support for stateful workloads

4. Relatively static Ansible integration

Resource Management

• Resources must be defined in .cloud file

• Manual changes to resources may cause sync issues

• Key pairs are managed automatically

• Some resource types require manual cleanup

Best Practices

Project Organization

1. Use different names for all resources within each .cloudfile

2. Separate configurations by deployment zone

3. Document file references

4. Maintain backup copies

Troubleshooting

Common Issues

Convert Command Fails

Error: No .cloud file found in the specified path

Solution: Ensure you're providing the correct path and the .cloud file exists.

Network Access Issues

Error: Could not establish SSH connection to instance

Solution:

1. Check security group rules

2. Verify instance has public IP

3. Confirm SSH key permissions

4. Check OS user configuration

Permission Issues

Error: AWS API call failed: AccessDenied

Solution:

1. Verify AWS credentials

2. Check IAM permissions

3. Ensure role/policy attachments
