Ansible feedback and dynamic inventory

[benasse]

Hi everyone,

For about 1 month ansible is working well through Shellhub. This is great news! 🎉

I wanted to share with the community a script that generates dynamic inventory from a namaspace : https://gist.github.com/benasse/0658a773c089f46d51e7b2b37c82cfd4

At the moment the execution time is not optimal, this comes from the fact that multiplexing ssh / Controll Master is not implemented yet.

A PR for its support is underway on the golang side, and some seem to have implemented it on their side.

I don't know how complicated it is to add it to Shellhub.

Hi, @benasse,

I've been investigating this issue, and I can confirm that it has not been fully implemented yet. It seems like ShellHub can initiate a multiplexed session, but it fails to manage multiple "non-background" sessions on the same "master" connection.

For instance, when an authentication is done with ssh [email protected]@localhost, it works fine initially. However, subsequent attempts result in failure with the message Shared connection to localhost closed. Likewise, when authenticated with ssh -fN [email protected]@localhost, the subsequent connection reuses the "master" connection, but subsequent calls still fail with the same Shared connection to localhost closed..

I will work on a fix for this issue and keep you updated. Thank you for reporting it.

I opened issue #3656 to track this

oh great, I'll try it when the next RC version is released! 🙂

Hi @heiytor ,

I just tested version v0.18.0, connections through ansible are now much faster, multiplexed connections seem to work.
Do you think #3656 could be closed ?

Hi @benasse

Thanks for the reply! And yes, we can close the issue now.
