Re: Disk space is too low. Only "less than a GB" left on /var/lib/jenkins
Few methods which we employ to save on space is by using 1. any "post-build" for any job to delete job workspace if not needed. 2. Limit the number of job build logs to minimum - say around 2-4. 3. Install this disk usage plugin - https://wiki.jenkins.io/display/JENKINS/Disk+Usage+Plugin which helps monitor.

Re: Can i run master and slave on same machine
I have set up a single machine to run as jenkins- master+slave successfully many a times , been able to deploy jobs successfully as well on the machine at "Remote root directory" for the added slave node .Every job deployed creates a folder with the job name . Can you elaborate more on where exactly ur getting this message - 'file available" , any launch methods which is giving this message - JNLP, SSH , webstart, etc. ?

Re: Creating groovy script to configure slave node properties >> "Restrict jobs execution at node"
Hi Indra,
Got it working with the below changes to my groovy script . Copying the
updated script for benefit of others
import jenkins.model.*
import hudson.model.*

import hudson.plugins.sshslaves.*
import com.synopsys.arc.jenkinsci.plugins.jobrestrictions.nodes.

import java.util.List;
List usersList;
UserSelector u1 = new UserSelector ("user1");
List userlist = new LinkedList();
userlist.add(u1);
StartedByUserRestriction startuserrect = new StartedByUserRestriction(
userlist, false, false,false );
JobRestrictionProperty jobrestrict = new JobRestrictionProperty(
startuserrect);
List restrictlist = new LinkedList();
restrictlist.add(jobrestrict);
Slave slave = new DumbSlave(
"agent-node",
"Agent node description",
"/home/jenkins",

"agent-node-label",
new SSHLauncher("172.17.1.55",22,"root","root","","","",
"",""),
new RetentionStrategy.Always(),
restrictlist)
Jenkins.instance.addNode(slave)
Thanks for all the guidance and pointing out the detailed steps.
Thanks and regards,

Re: Creating groovy script to configure slave node properties >> "Restrict jobs execution at node"
Hi Victor, Thanks for quick comment. I had already looked at the below repo of "job-restriction plugin" - https://github.com/jenkinsci/job-restrictions-plugin/tree/master/src/main/java/com/synopsys/arc/jenkinsci/plugins/jobrestrictions However i am unable to figure how do i change the slave node >> configure >> Node Properties >> Restrict jobs execution at node via a groovy script ? Any pointers on how can i bring out the above change might be helpful.

Creating groovy script to configure slave node properties >> "Restrict jobs execution at node"
Hi All, I am trying to automate the process of creating a slave node on jenkins server , creating users and then and also allow certain users to access only certain slave nodes. The automation is to be achieved via a groovy script. Here's my script thus far import jenkins.model.* import hudson.security.* import hudson.slaves.* import hudson.plugins.sshslaves.* import hudson.model.* SLAVE_IP_ADDR="172.17.1.55" SLAVE_LOGIN="root" SLAVE_PWD="root" SLAVE_NODE_LABEL="My_Slave_Node_Autogenerated-Label" println "create a slave node.. \n\r" Slave slave_node = new DumbSlave( "My_Slave_Node_Autogenerated", "This slave node is generated using a jenkins job via groovy script", "/home/jenkins", "1", Node.Mode.NORMAL, SLAVE_NODE_LABEL, new SSHLauncher(SLAVE_IP_ADDR,22,SLAVE_LOGIN,SLAVE_PWD,"","","","",""), new RetentionStrategy.Always(), new LinkedList() ) Jenkins.instance.addNode(slave_node) So doing above , i am able to achieve creation of slave nodes, now what i want to do is to restrict the users created ( done by a groovy script too ) to have restricted access to the slave nodes created above. For this we need "job-restriction" plugin installed. I have version 0.5 installed on my server. Post installation of the plugin ,i have " Restrict jobs execution at node " option seen under " Node properties " for any slave node configure setting. Now i can manually on the jenkins UI , i am able to achieve restriction of users created for any slave node , however do i get this automated using a groovy script. Any thought how "Restrict jobs execution at node " can be achieved using a groovy script ? Any pointers will be helpful Thanks and regards, Amit I -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
