My Jenkins UI takes parameter a list of files/folders along with wildcards from users that they wish to delete.
Jenkins then passes the files to be deleted across all hosts by invoking ansible-playbook.
My requirement is to prompt user on Jenkins for confirmation before deleting a file / folder.
Thus, how rm -rfi /tmp/moht /var/log*/data.dat prompts interactively asking the user confirmation before deleting the files; is what I Wish to prompt on Jenkins for each Host.
Thus, for the above I expect Jenkins to prompt like below:
Are you sure you want to delete
/tmp/moht
/var/log14Mar/data.dat
I'm aware of input function in Jenkins for prompt.
I'm also aware of an ansible command module that can be used to fire rm -rfi command.
I'm also aware of how to timeout or terminate the Jenkins Job upon user input. However, in this case I would love if the user input Yes / No could be sent back to the target host via ansible and action gets performed accordingly.
I understand that this may be too much an ask but other feasible solutions or suggestions are also appreciated.
Can you please suggest how can I achieve the requirement?
I strongly feel that using Jenkins as interactive tool is a bad idea. But if you really like to implement bad ideas with unsuitable tools, you can try to use matrix job [1] based on files you want to remove.
Jenkins will create a list of jobs with a job for each file you'd like to remove. You ask confirmation and then execute an Ansible playbook to remove a file.

It's horribly inefficient and you should not do it like this.

I am trying to setup a jenkins server for the very first time. I have synced it to the Perforce server I use, and I have created a workspace for that. Now I would like jenkins to start building everytime a change is submited, I have been researching through the topics here, and I found this link: How to trigger a Jenkins build on a Perforce submit. But it mentions that in order to do that I have to create a script on the P4 server On the Perforce server, it is possible to create triggers or, in other words, scripts to be run on a particular event - for example after a change-commit., I do not know what it means to create a script on the P4 server. Does it mean I need to have physical access to the server? I am just connecting to a remote server. I am kinda lost here...
Ideally, you'd have access to be able to create a trigger. If you can't do that, the next best thing is to create a cron job or scheduled task (depending on your OS) to check to see if there is something new. I've run similar jobs to:
Run p4 sync -n to see if there is anything new
If there is something new, a) sync it and build it (your choice of everything, or you could write something that would test, say, the first changelist for which there is something new, then keep doing so changelist-by-changelist)
If there is already a build in progress, don't run.
My jobs were set to check every five minutes, but I even had a project where once/hour was enough.
I occasionally want to get notified when a particular jenkins job that is building finishes. Is there any way to do this?
Scripting it through the API would be fine. I already have the jenkins IRC bot that notifies me of many things, so if I could just dynamically modify the running job build, that would be enough to do what I want -- I'm just having a hard time finding how to accomplish that.
AFAIK, you cannot change a job's config while it's running.
Here is an idea: Use a post-build step to check for an external resource status (like a file containing an action by text) and running an action based on the content of the file.
The external file can be modified while the build is running, so when the post-build is executed, it will follow the logic defined based on the content of the file.
I hope this helps.
You can use email notifier, It will send you an email

Is there a way to get the hudson job initiated user name.
Is it possible to get using script shell, py etc.
Lets assume I have the build # which was initiated. I know how to get the latest build info using api but would like to get a user details for a specific job.
Do you think, this will work for hudson? :)
https://wiki.jenkins-ci.org/display/JENKINS/Build+User+Vars+Plugin
Thanks in advance
That plugin will not work with Hudson, unless you download a very old version of the plugin. I'm not sure how many people are still using Hudson and haven't upgraded to Jenkins.
Anyway, when a user manually triggers a build, this is called a "user cause"; there are other types of cause, e.g. SCM trigger.
You can use the JSON or XML API to get the causes for a build, for example:
https://ci.jenkins-ci.org/job/remoting/lastSuccessfulBuild/api/xml?xpath=//action/cause/userId
In this case, this returns the username that caused the build to run.
Though note that there may be multiple causes for a build, and potentially other cause types that use the userId field.
This works in Jenkins, but it should also work in Hudson, but I haven't tested it.
Currently in order to enable or disable a job, a user must have Job Configure permissions in the Matrix-based security configuration.We would like to be able to manage the enable / disable job permission independently from the job configure permission.
There are some nightly jobs that we want every user to be able to enable and disable the project without touching/breaking the configuration.
Thanks
Provide a script for the users that will do this using the credentials of 'root' user and set only the execute bit on the script so that no one can read/copy it.
At least 3 ways to make a script:
HTTP POST request:
1.
curl -X POST http(s)://<your_jenkins_url>/jenkins/job/<nightly-build_job_name>/disable
2.
Use python JenkinsAPI.
Documentation is very good, easy to understand much like the API.
3.
The third one can be a script which will use jenkins-cli: accepted answer describes this well .
The Job Configure permission is bounded to the disable/enable function in each job, that's true.
One alternative to disable/enable jobs without the corresponding permission is to create new jobs which do this internally. For example, a job that needs job names as parameters, and disables them.
You could use curl + credentials of a Jenkins user with the Job Configure permission.
You could use plugins. For example, this script using the Job DSL Plugin:
job("jobname"){
using("jobname")
disabled(true)
}
For other options, check out this question.
You may try to install this plugin to get the enable/disable button for the individual project-
I checked in my Jenkins and I could see this:
But when I checked under plugins section I don't see this extra column plugin installed. Probably this is the default behavior in latest versions of Jenkins.
My question may be silly but I've been trying several ways and I still can't do what I want, i.e.:
use the scp target of Ant to target a remote machine and execute
a script there
this script creates a dynamic list of files
get this list of files (only their names) back in Hudson to use it in the next build step (another scp from Ant)
I tried to use environment variables but they are interpreted by Hudson so I'm stuck here...
Globally my question would be: how to get a result from an Ant build step ?
Thanks for your ideas,
Emmanuel
You may find File parameter useful. This allows you to create an input file, pass it to build. You may need to write script/ant script to process the file though.
In the long term you may evaluate a Hudson farm. This will allow to create tasks that span multiple machines , pass results around. (https://wiki.jenkins-ci.org/display/JENKINS/Plugins)
You can get the ID(s) of the job that triggered your job via the API and fetch their status.
