[JENKINS-69575] swarm plugin update from 3.34 to 3.35 break agent git clone (assumption)

Type: Bug
Resolution: Fixed
Priority: Critical
Component/s: swarm-plugin
Labels:
None
Environment:
openjdk 11.0.16 2022-07-19
Jenkins 2.367
debian bullseye

Similar Issues:
Powered by SuggestiMate

Show
Released As:
3.36

Jenkins controller is behind load balancer, all external communications are done through proxy.

After upgrade to swarm plugin 3.35 git clone fails on the agents.

Exact same config works fine with 3.34.

Description

Original: Jenkins controller is behind load balancer, all external communications are done through proxy.

After upgrade to swarm plugin 3.35 git clone fails on the agents.

Exact same config works fine with 3.34.
