Starting a job with jenkins user gives ssh error

[mani chandel]

Hi All,

 

I am trying to integrate Jenkins with gerrit on my local environment.

I started a job with Jenkins users but it gives me this below error. Please help.

 

Started by user gerrit developer
Building in workspace C:\Program Files\Jenkins\jobs\test_job3\workspace
[workspace] $ cmd /c call C:\Windows\TEMP\hudson2558238243811788130.bat

C:\Program Files\Jenkins\jobs\test_job3\workspace>ssh -p 29418 gerrit_developer@localhost gerrit ls-projects  1>>logfile.txt 
Permission denied (publickey).

C:\Program Files\Jenkins\jobs\test_job3\workspace>exit 255 
Build step 'Execute Windows batch command' marked build as failure
Finished: FAILURE

Regards,

Mani

You need to make sure the public key is available for the user the Jenkins service is running out to allow it to login to Gerrit.

This won’t be the same as the user of the person logged into the desktop.

 

Note if you use the Jenkins Gerrit Trigger Plugin then it gives you the option to specify the keyfile.

If you can't interpret the output of 'ssh -vv ...', we can help and
suggest the next steps.

Hi Thomas,

 

I have specified the ssh keyfile in the gerrit trgger as below and also clicked on test connection. It shows success. However, I still face this issue. Please let me know if I am missing something.

	Hi Magnus, On executing this command on cmd ssh -vv -p 29418 gerrit_developer@localhost I get below output. debug2: channel 0: input open -> closed debug2: channel 0: obuf_empty delayed efd 6/(294)   ****    Welcome to Gerrit Code Review    ****   Hi gerrit developer, you have successfully connected over SSH.   Unfortunately, interactive shells are disabled.   To clone a hosted Git repository, use:   git clone ssh://gerrit_developer@<IP address>/REPOSITORY_NAME.git   Regards, Mani	Test Connection

[Thomas Swindells (tswindel)]

The gerrit trigger config will only control the ssh key used by the Gerrit trigger to perform the polling.

The actual git clone command is separate from this and run on whatever machine the Jenkins executor is running on (presumably in this case your local machine) and this command has to have had its git ssh setup done correctly.

My 2 cents: possibly Jenkins NOT running under user "253673" ? 

;-)

Hi Luca,

I have logged into my computer with user 253673.

And for jenkins I have created a user called gerrit_developer and have given all rights to it.

I am running jenkins with gerrit_developer user.

I have set the  HOME variable in windows which points to my user profile C:\Users\253673 where I have kept the .ssh folder which contains id_rsa keys (private and public).

Regards,

Mani

Hi Magnus, On executing this command on cmd ssh -vv -p 29418 gerrit_d...@localhost I get below output.

Test Connection

[Luca Milanesio]

So, that's the problem: Jenkins needs to run under the user 253673 *OR* assign the keys to your gerrit_developer user.

Example: I am user A and I use SSH keys of user A. If a login as user B I cannot use A's SSH keys.

This is not Gerrit or Jenkins specific concepts, it's simply SSH :-)

Luca.

[mani chandel]

Hi Luca,

Gerrit_developer is my jenkins user.

Please let me know how can I assign SSH key of 253673 to this user.

I am running jenkins and gerrit both on localhost.

Regards,

Mani

[Luca Milanesio]

Try with:

C:\> COPY C:\Users\253673\.ssh\*.* C:\Users\gerrit_developer\.ssh
