I have lot of slaves added (nearly 500) to on jenkins server (1.573) in production. I am trying to setup new jenkins server as sandbox. I need the to move some slave machines from production to sandbox environment. I tried to coipy the slaves tag from prod jenkins config.xml and copy to new sandbox jenkins server (same version as prod) and then consolidate the details. But whenever i copy the dsetails and give "Reload from server", the newly added slave details are all reset and it gives me empty list in the nodes.
could any one explain oir give a way to accomplish the above described task ?

we have 150 applications which has individual jenkins file for each application in Git repository. we deploying each application one by one in Jenkins by triggering desired branch and when it reaches to k8s deployment stage in pipeline, we need to select the environment dev/test/prod from the dropdown there to deploy in desired environment. Now I need help to prepare a single jenkins job to deploy all the 150 applications to k8s at a time. Please suggest step by step process if any..
I would like to set up jenkins server that would run test scripts based on successful build deployments on other Jenkins servers. for example, if the QA jenkins server is named JQA1OnMachine1 and i have three others that are named
J2OnMachine2, J3OnMachine3, J4OnMachine4 (different jenkins server on different boxes) can the JQA1OnMachine1 (QA jenkis) poll the others at regular interval to see if a build was deployed successfully? if so can anyone tell me how?
Jenkins master slave along with Jenkins Pipeline Plugin would be one of the better ways to implement this however, since you don't want to use that approach you can explore PSTools to remotely capture processes or files on different server.
Your builds may update a file on the build server post completion of the build and your QA machine can run script with PSTools to monitor and trigger the QA testing based on the file content
I'm setting up a development environment where I have Jenkins as CI server (using pipelines), and the last build step in Jenkinsfile is a deployment to staging. The idea is to have a staging environment for each branch that is pushed.
Whenever someone deletes a branch (sometimes after merging), Jenkins automatically removes its respective job.
I wonder if there is a way to run a custom script before the automatic job removal, then I would be able to connect to the staging server and stop or remove all services that are running for the job that is going to be deleted.
The plugin multibranch-action-triggers-plugin might be worth a look.
This plugin enables building/triggering other jobs when a Pipeline job is created or deleted, or when a Run (also known as Build) is deleted by a Multi Branch Pipeline Job.
I'm new to Jenkins, and I like to know if it is possible to have one Jenkins server to deploy / update code on multiple web servers.
Currently, I have two web servers, which are using python Fabric for deployment.
Any good tutorials, will be greatly welcomed.
One solution could be to declare your web servers as slave nodes.
First thing, give jenkins credentials to your servers (login/password or ssh login+private key or certificate. This can be configured in the "Manage credentials" menu
Then configure the slave nodes. Read the doc
Then, create a multi-configuration job. First you have to install the matrix-project plugin. This will allow you to send the same deployment intructions to both your servers at once
Since you are already using Fabic for deployment, I would suggest installing Fabric on the Jenkins master and have Jenkins kick off the Fabric commands to deploy to the remote servers. You could set up the hostnames or IPs of the remote servers as parameters to the build and just have shell commands that iterate over them and run the Fabric commands. You can take this a step further and have the same job deploy to dev/test/prod just by using a different set of hosts.
I would not make the webservers slave nodes. Reserve slave nodes for build jobs. For example, if you need to build a windows application, you will need a windows Jenkins slave. IF you have a problem with installing Fabric on your Jenkins master, you could create a slave node that is responsible for running Fabric deploys and force anything that runs a fabric command to use that slave. I feel like this is overly complex but if you have a ton of builds on your master, you might want to go this route.
I want to configure Jenkins to build my code on 1 server. Then want to deploy it on another server using Jenkins.Both servers are using Linux I want to automate the entire process as much as possible. I went through some of plugins like pipeline, Job Import Plugin, etc
Can anyone guide me how to go about it ? Which plugins will be useful ? Any example or tutorial somewhere will be useful. The configuration of build pipeline plugin on jenkins was not seamless for me.
Thanks,

I would work it this way :
Install jenkins on your first server
Install the following plugins : ssh credentials, ssh slaves, copy to
slave, and restart jenkins
Go to Manage jenkins -> Manage credentials, and add ssh credentials
for your second server
Go to Manage jenkins -> Manage nodes, and create a passive slave.
The launch method should be "Launch slave agents on Unix machines
via ssh". You should use the credentials that you have added in step
3
Create a job to build your code. In the advanded options of job, you
should indicate that the job must only be built on master node.
Create a job to deploy your code on the second server. In the
avanded options of job, you should indicate that the job must only
be built on slave node.
In the "Build Environment" section, check the "Copy files into workspace before building" box and configure what files you want to copy from first server (https://wiki.jenkins-ci.org/display/JENKINS/Copy+To+Slave+Plugin)
The code will be copied into the jenkins slave's workspace.
