Jenkins setup:
- Current version: 2.440.2-lts
- EC2 instances as part of ASG in AWS
- Docker Swarm
Please help! We recently tried to upgrade the Jenkins controller version to 2.479.1, but there were compatibility issues with the worker nodes, which only were using JDK11(EC2 instances in the same VPC). As a result, we tried to roll back the changes using a previous snapshot and accidentally killed our whole Docker service stack, although the ec2 workers do still exist. We also had to replace the old controller nodes with new ones during the process of restoring from the snapshots. We are now at the point where the Jenkins controller UI comes up and is accessible, but any jobs get stick in the build queue, as it seems like the controller and workers nodes cannot communicate. It seems like the issue could be with the SSL certs, which are new. Has anybody ever had luck getting like emergency support? Or has anybody experienced a similar issue before and have any tips? Thanks in advance!
For info - all of the jobs get stuck in the build queue, saying that:
*Docker swarm agent for building part of » st-web-portal » PR-69 #2* *This agent is offline because Jenkins failed to launch the agent process on it.*
and the logs seem to indicate an issue with the SSL handshake:
