Re: mvn not found on $JENKINS_HOME/workspace/@tmp
Hi :) >From the previous email, I asked for help about my Jenkins Slave unable to run mvn I'd like to share what I've founded and the solution for the problem. I basically set the PATH for M2_HOME and MAVEN_HOME at /etc/profile which is somehow not work with the system's permission So, I changed to set M2_HOME and MAVEN_HOME at /etc/environment instead and then the problem was gone :D It's not Jenkins issue not even relate LOL but it's Linux 101 Anyway, amy thanks for Mallarapu Ananth and John for the suggestion.

Jenkins installation freeze at install plugin page and unable to continue
I've installed native *Jenkins 2.263.3* (latest stable Debian package ) and Java openJDK 8. The installation was successful. However, once the installation came to the step "Customize Jenkins" and there were options to either choose *Install suggested plugins* or *Select plugins to install*. Both give the same result. Jenkins UI will freeze for about a couple of seconds and then the error page shows as pictured below.

Needed suggestions for Jenkins Master/Slave architecture
Hello Folks! I'm about to set up New Jenkins cluster with Master/Slave model. Actually, we already have Jenkins master-only running but it's usually faces run out of memory issue. I've read all the recommended on the official, however there are some details missing there. *1. Please suggest for storage for both Master and Slave. Currently our Master-only Jenkins uses huge disk spaces (~200GB) and it tends to increase along with the number of new jobs.* My question is where does ./workspace, ./jobs and ./caches (most biggest directories) under $JENKINS_HOME will store? in Master or Slave? *2. If I mark Master as drain node (not executing job), so my master can possibly has a minimal resources e.g. CPU 1vCPU and 4GB or less number of memory ?* **for my current Master-only Jenkins, we have 30GB memory/200GB *3. If there any issue or concerns from migrating Master-only to Master/Slave ? * Any suggestion would be appreciated :) Cheers, -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.

Is it possible for provisioning Jenkins agents with Docker plugin as a Swarm cluster ?
Dear folks, I have one huge production Jenkins master which is contains projects over 50. This Jenkins master act as a build and scheduler machine. Then I've been facing the issue about the Jenkins performance and its run out of resources. So I'm trying to do the optimization by change its architecture to Master/agents. The concerns are, I have limited number of agent and limited resources per agent. Hence, I would like to find the best approach that can provide us for acceptable costs and the difficulty of the management. So, I came up with the solution using Jenkins plugin *'docker plugin' *with can operate with the minimum resources perfectly. I've tested with my test cluster but the scenario was Master/Agents in the same machine using docker plugin. It works well. Then I'd like to implement in my production Jenkins with this docker plugin but I don't want to spawn agents node in the same machine. I want to join agent nodes to the swarm cluster. Does it possible ? -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
