Centos – Provision of OrbStack with Ansible

The following problem:
OrbStack (Centos-8) is only reachable via "ssh orb".
This works 100% under zsh/OSX.
But no configuration of an Ansible inventory makes it possible to play a setup via Ansible on the Centos machine – e.g. to install Django on Centos.
The address "centos8.orb.local" is reachable via ping and returns "198.19.249.149". But neither "centos8.orb.local" nor "198.19.249.149" can be used in an inventory by Ansible.
Ansible is apparently not able to communicate with OrbStack.
Who knows the problem and found a solution for it?

    The issue you’re facing with Ansible not being able to communicate with OrbStack on CentOS-8 may have a few potential solutions:

    1. DNS Resolution: Ensure that DNS resolution is working correctly on your CentOS machine. Check the /etc/resolv.conf file to confirm that the DNS settings are properly configured.

    2. Hosts File: You can try adding an entry to the /etc/hosts file on your CentOS machine to map the hostname "centos8.orb.local" to its IP address "198.19.249.149". This can help Ansible resolve the hostname correctly.

      echo "198.19.249.149 centos8.orb.local" | sudo tee -a /etc/hosts

    3. Check SSH Configuration: Ensure that SSH is correctly configured on your CentOS machine. You can test SSH connectivity by running:

      ssh centos8.orb.local

      If this works, it means SSH connectivity is established.

    4. Ansible Inventory: Double-check your Ansible inventory file for any syntax errors or misconfigurations. Make sure the hostname and SSH credentials are correctly defined.

    5. Firewall and Security Groups: Check if there are any firewall rules or security group settings on your CentOS machine that might be blocking Ansible’s access. Ensure that SSH port 22 is open.

    6. SSH Key Authentication: If you’re using SSH key authentication, verify that your SSH keys are correctly configured and that Ansible is using the correct key.

    7. Ansible Debugging: You can add the -vvv flag to your Ansible command to enable verbose output. This can provide more information on where the connection is failing.

    8. SELinux: If SELinux is enabled on your CentOS machine, it might be blocking Ansible’s access. You can temporarily disable SELinux to see if it resolves the issue. However, it’s recommended to configure SELinux properly instead of disabling it entirely.

    9. Proxy Settings: If you’re behind a proxy, ensure that Ansible is configured to work with the proxy settings.

    10. Network Configuration: Double-check the network configuration on CentOS-8 to ensure it has the correct gateway and subnet settings.

    I hope these steps will fix your problems. Kindly let me know

    I just used orb as the hostname, and it works.

    And maybe this piece from the official doc helps.

    For apps that don’t use OpenSSH, you can use the following connection details:

    Host: localhost
    Port: 32222
    User: default (or any of the examples above)
    Private key: ~/.orbstack/ssh/id_ed25519
