You should be able to find the original configuration for the nodes and clouds in your backed-up config files.
Copy/Paste the information into your new config file.
The configuration for nodes and clouds in Jenkins is stored in the config.xml
files. These files can be found in the Jenkins home directory, under the nodes
and clouds
subdirectories.
For example, if your Jenkins home directory is /var/lib/jenkins
, the configuration file for a node named my-node
would be located at /var/lib/jenkins/nodes/my-node/config.xml
.
