Molecule doesn't work well with WSL2

[SilverknightMel]

My environment: W10 laptop WSL2, Ubuntu 20, molecule 3.0.8 molecule-vagrant 0.3

I can create win2019 VM in virtualbox via Molecule create, but can't reach VM after creation and configure winrm. I can run small ansible-playbook to reach from Ubuntu 20 to win2019 VM and create folder. ssh [email protected] -p 2222 is working too. but got follow error message.

ERROR: `

Any ideas why Molecule can't reach win2019 VM in virtualbox?

[apatard]

The error handling from molecule-vagrant 0.3 is not so good, leading to a not very helpful message. Can you try git HEAD to see if you can get a better error message ? Moreover, be informed that winrm connection support is missing, as mentioned in https://github.com/ansible-community/molecule-vagrant/issues/98.

[SilverknightMel]

@apatard , I'm so sorry. I'm very new to molecule and others. How to git HEAD to see better error message?

Also, my colleagues working on Mac and they have no issues with Molecule + winrm , is this WSL 2 thing? (also I have trouble with WSL 1). Are you saying winrm connection is no good for molecule and win2019 and suggest to use ssh instead? I had a very brief time that when I switch Ansible connection with SSH and then after I tried few things and it's gone. I can't really reproduce SSH connection again. Are you suggesting I should use SSH on Molecule settings and Ansible settings and rebuild VM in virtualbox?

[mannahusum]

I've had similar issues with WSL2 and HyperV. For the they turned out to be related to the configuration of the virtual network switches created by Windows. I run a small snippet of PowerShell as a user with administrative rights in order to remedy this:

Get-NetIPInterface | where {$_.InterfaceAlias -eq 'vEthernet (WSL)' -or $_.InterfaceAlias -eq 'vEthernet (Default Switch)'} | Set-NetIPInterface -Forwarding Enable

These changes unfortunately are not permanent. I'm planning on creating a ScheduledTask I can trigger from WSL2 in order to make it permanent unless anybody has a better solution

I hope you solved this problem before and this is just for the next person stumbling over this.
