Problem: The Ansible playbook for NAT rules fails with a sudo: a password is required error.
Cause: This happens because the Ansible playbook attempts to perform operations with root privileges (become: true) on localhost (the machine from which you are running the script), but it does not have a password for sudo.
Solution: Ensure that the Ansible task modifying local files (like inventory-nat-rules.ini or ssh_connections.ini) has become: false explicitly set. This tells Ansible not to use sudo for that specific task, as root privileges are not required to modify files in your user directory.
Problem: The git filter-repo command is not recognized or fails during history rewriting.
Cause: git filter-repo might not be installed or not be in your system's PATH.
Solution: Install git filter-repo using your preferred package manager. For example:
- Python pip:
pip install git-filter-repo - macOS Homebrew:
brew install git-filter-repo
Problem: You cannot connect via SSH to VMs after deployment.
Possible Cause: NAT rules might not have been applied correctly, the Proxmox host's firewall might be blocking connections, or the VM might not have started the SSH service correctly.
Solution:
- Verify NAT Rules: Check the deployment output to ensure that NAT rules were successfully configured. You can also access the Proxmox host and manually verify
iptablesrules (iptables -t nat -L PREROUTING). - Proxmox Firewall: Ensure that the Proxmox host's firewall is not blocking the ports you have mapped. You might need to add rules to allow incoming traffic on the NATted ports.
- VM Status: Check the VM status on the Proxmox VE UI. Ensure it is running and that the SSH service is active within the VM.
- SSH Key: Verify that the specified SSH key is correct and that you are using the full path and correct permissions (
chmod 400 your_key_file).
