My company is using Jenkins for their CI and so far we've only been using it for our web apps, but now we're getting to the windows service apps we use and I'm looking for some guidance on this.
Currently we have a batch script that shuts down the service then do an Hg update and then turns the service back on.
I need Jenkins to run it as admin so that windows will allow the script to toggle the services.
My question is, how hard is it for Jenkins to run something with elevated privileges?
With PsService you can execute a remote command (start/stop/restart) and provide a username and a password for elevated access.
Once you manage to do this all you need to do is to "write that line" in jenkins. Meaning that if you use pipeline you'll do it with credentials binding. Of course you need to create jenkins credentials with the aforementioned username and password.

I have a jenkins job that uses ssh to connect to the scheduler user on a quartz server; it can restart quartz as the scheduler user, and the processes and libraries appear to be owned by the scheduler, but whenever an encrypt/decrypt task is run, it thinks it's being called as the jenkins user instead of the scheduler.
ID and env indicate that the remote shell is running as the scheduler user - why does the encrypt task look to the jenkins .pgp directory? The only way for me to fix this is to ssh to the box myself, sudo to the scheduler, and restart the jobs. How do I get jenkins to emulate this?
You would need to record your own private key in Jenkins, through the JENKINS SSH Credentials Plugin.
That way, Jenkins would be able to use your own SSH credential when diong its SSH step, connecting to the quartz server as you instead of jenkins.
I finally spotted the source of my problem, and I'm so embarrassed - the scheduler user's home directory was actually owned by jenkins, with the scheduler user as the group owner. No wonder pgp looked in the jenkins directory for its info. I must have changed ownership to jenkins earlier when I was setting things up, but that wasn't a very good idea.
Thank you for responding - it is great to have some company when one is confused and needing a different perspective.
I am trying to create a new directory and copy files to it. So I'm using a job of "Execute batch command".
First I tried to run: robocopy source destination /e.
Then I tried: mkdir destination. In both cases I got an "Access is denied" mssage.
If I try it myself manualy I am able to create a directory and copy files to it.
The destination is a remote computer's shared folder: \computerName\sharedFolder\
Anyone knows how to get access rights with Jenkins?
I know this post is a bit old but I found two solutions that work pretty well so I'm posting it in case somebody needs it.
First: allowing the disk usage for the current run
On your "Execute batch command" you can add a line:
net use \\server\folder /USER:domain\user password
You can then use \server\folder in your commands and it'll work.
Jenkins can even deal with credentials so that there's not in plain text.
The second solution is to boot Jenkins as a specific user so that all the commands will be run as this user.
To do this:
Open services app in windows
Search for Jenkins
Right click, properties
On Log On tab configure the credentials you want to use
Reboot Jenkins
I hope this helps someone
To find out the user under which your jobs run, create a "scratch" job in Jenkins. Give it a single "Execute Windows Batch command" build step and enter "set" as the text of your batch command. If your affected job is running on a Windows slave, make sure this job runs on the same slave. Run the job. Your console will show a list of the environment variables known to that job, the same as if you typed "set" in a Command Prompt window on your desktop. The difference will be that near the bottom, the username shown for "USERDOMAIN" and "USERNAME" in your command window will be you (the user you are logged in as); in the console output, it will be the user account that your Jenkins job runs under.
That user may not actually have login rights. And, if Jenkins is running as a service, you can't just set up a share in your command window: Jenkins jobs run under a different Windows "session" and that session will not see the share you created in your login session.
A not-very-secure way to get you over the hump would be to add parameters to your job for the username (string parameter) and password (password parameter). Before you need access to the drive, either in the same build step or in a 'Execute Windows Batch Command' step that runs prior to that build step, run "#net use : \computername\sharename %% /USER:%% /persistent:no". (for example: "#net use p: \COMPUTER\SHARE %PASSWORD% %USER% /persistent:no"). The "#" will keep the password from showing in the log. (However, the password will be associated with the job and will be encoded in Jenkins if "Allow rebuild" is enabled.) Make sure when you are done you clean up ("net use /delete") and you may need to test and clean up the drive letter before you try to connect, in case a previous job failed without releasing the drive letter.
In this scenario you would have to enter a username and password for someone who can access the share when you run the job. You could encode hidden parameters with these values pre-filled in, but that means that user's username and password are encoded into the job definition, and the default for the hidden password parameter would not be encrypted in the Jenkins config files.
There are definitely more secure ways to get the drive share enabled in the Jenkins service session, but depending on your environment this may be 'good enough' to get you past the block you are faced with right now. I have used tricks like these in an environment where I was not a Jenkins administrator and I had very limited access rights (and no admin rights) on the Jenkins slaves.
In my setup, the Jenkins slave service runs under a specific user (named jenkins).
It makes it easy to verify the access rights for that specific user.
Of course jenkins needs to have write access on the remote folder, both on the physical disk and the share.
I have a jenkins setup with multiple users which are logging in with Active Directory plugin. This is useful so that each user can access his own tasks.
However each user also has different permissions on the local network, such as access to different folders etc. I have noticed that the permissions given to each task is not linked to the user but to the account under which the slave is running as service. Is there a way to change that so that the task is executed on the slave under the credential (and hence permissions) of the user?
Thank you
The problem is: there is only one slave process running the different job assigned to that server by the Jenkins master.
So the slave itself runs as one user (generally, a dedicated account or a system account).
Since you can get the user id as environment variable (with a plugin like JENKINS Build User Vars Plugin), you might consider configuring the job in order for it build step to "run as" the user who triggered the build.
See for instance the JENKINS Authorize Project plugin.
However, as mentioned this answer:
The "Authorize Project" plugin does not change the OS level user that is running commands.
It only sets the Jenkins user that is running the job and any downstream jobs, using Jenkins authentication (whatever it might be).
So you are left with build step with runas or su -c commands in order to be sure that your task does run with the right user.
I had the similar issue and I can recall for managing more control on projects I used role strategy plugin and setup global security using LDAP servers (Active directory should also be ok).
And I used authorized project plugin.
Have a look and I hope it should solve your purpose. Let me know on comment section for any clarification.
you can partially fix your problem this way:
install the slave as a service using the Java Web Start method and JLNP
go to Services control panel in windows
under Properties -> Connection replace the local system connection with a specific user
rebooted the service
This at least gives you the ability to use one account instead of system.
I need to execute few of the Jenkins jobs such as "Release to Production" through Jenkins UI using logged on user credential. The reason is, we have separate Support Team Members, who have access to the production boxes and not the Dev team members. So, in order to deploy any code base to production, all the Windows Deploy Commands (ex, create, update files, folder etc.) needs to be run with specific user credential who has access to the Production Box. So that even the Dev team members who don't have access to the Production box but are Jenkins Admin, execute the same job should result in failure due to "Access Denied". The job should succeed only if its been run by Support Team members with their credential.
I tried using parameterized plugin but couldn't able to pass the Password successfully to the batch file which contains MSDeploy instructions. Even the Jenkins console log displays the parameter passed in its console output, which is a security issue.
I checked Role based security plugin, but that doesn't help me much. I just need a plugin which should ask for user to provide their credential before start building the Job and should use the user credential to get the job executed, so that my MSDeploy command will be able to deploy the code on Production boxes, when the Support team member build that Job using their credential. I wish there was support for impersonation.
Right now all the Jenkins Jobs are getting executed using the service account which the Tomcat service is configured to run with on which Jenkins is hosted.
Any help would be appreciated.
Just in case there is any confusion a Jenkins job will always run as the same OS user. The Matrix based security applies to users who log into the Jenkins server and controls features like creating or launching jobs.
You could configure the job to use a set of generic production credentials and then prevent your developers from invoking the job.
Perhaps a better approach would be to separate the process that builds the code from the one that deploys the code. The following diagram (Taken from the xebia-france project) demonstrates how some of my favourite tools Rundeck and Nexus can be integrated with Jenkins.
Finally, I highly recommend reading the following link:

Hi I know I'm coming late on this thread, but I just fell on this issue and had a hard time solving it, so I thought I might just share what I managed to set-up.
First things first: if you want to run a Jenkins job "as a specific user" (with all the correct habilitations) the easiest way is to run a Jenkins SLAVE as this user.
Then you might very well stumble into the following: you probably want to run serveral slaves on the same windows machine as windows services. This is very fine, as long as each slave has his own Remote root directory and probably have a specific "label" too.
Once you managed to run your slave as a windows service, launch the service console (run services.msc). Edit the newly created service properties, go to Log On tab. Select "Log on as: This account" and enter your account credentials.
Cheers :)
You can utilize the built in windows runas or Powershell InvokeCommand cmdlet and -Credential to run - Both these would store the username/password in plain text - So do think about the risks, but this gives you flexibility.
I'm surprised this doesn't have a better answer of set an agent on another machine to run as another service and define agent as a special "type" which picks up the jobs - Something along those lines is what I would expect but I haven't seen an implementation like that in Jenkins (I'm new to Jenkins so was looking for an answer and found this thread).
Something else that could be considered for someone more familiar with Jenkins is when you set the custom path to MSBuild could you set that to runas /user:... msbuild.exe perhaps? I don't have an extra Jenkins server currently to try that on.
We are using Hudson as a CI tool. At present we are needed to use Jenkins, to deploy the build to Stage, Prod environment. What is the best aproach we should follow.
I know about promote buld plugin, but the issue is authentication. I want whevener we need to promote a build to deploy to Stage or Prod, it should ask for netqwork credential first. And then the promote job should execute the Batch command using the creadential supplied. At present, the promote plugin, runs using the credentials which the Tomcat server is configured to run.
Same issue with Build Pipeline plugin.
I want only dev or even hudson admin also should not be able to execute the promote build unless credential supplied. (We have windows 2008 r2 OS)
Can you please help me in resolving the issue. so that basically whenever a user click on Promote build to QA\Stage\Prod the plugin should ask for credential or should use the logged on users credential and execute the batch script using the logged users credential only and not by using the credentials of the account with which the tomcat server is configured.
Can you please help me?
Please suggests us the best aproach for making automated build on prod\stage.
For deployment I normally use SSH, Private/Public keys takes care of the authentication problems normally associated with running commands on other servers.
SSH is normally associated with unix based systems, but it does support windows.
Finally, I would recommend considering decoupling your build system (jenkins) from the system performing the deployment by using an intermediate repository. See the following answer for more details:
