Trigger job only when new file is placed in a folder Edited

We have a project which doesn't use version control tool. Developers will place the input files in the shared drive folder. Bamboo has to trigger the deployment plan only when new files are found in that location. It should be like Polling repository. Bamboo has to check the folder every 10 mins and triggers a job if new file is found. Is there a way to achieve this trigger in Bamboo?

Hi Elavarasan,

 

This isn't possible by default but you could build ascript (outside Bamboo) to look for changes in that folder and trigger a REST call to Bamboo to fire off a build if there's a change every 10 minutes.

 

Here is a guide to the Bamboo REST API documentation to get you started! In addition, here is a Sample script provided by one of the Bamboo Premier Support Engineers:

 

#!/bin/bash

COUNTER="COUNTER.txt"

DIRECTORY_COUNT=$(ls -lr | wc -l)

if [ ! -f $COUNTER ]; then
    # create counter file
    # used to store the amount of files/directories within a directory
    echo $((DIRECTORY_COUNT+1)) > $COUNTER
fi

COUNT=`cat $COUNTER`

if [[ "$COUNT" -lt "$DIRECTORY_COUNT" ]]; then
    # new file/directory was created
    echo "$DIRECTORY_COUNT" > $COUNTER

    # replace BAMBOO_ADMIN_USER with Bamboo administrator username
    # replace BAMBOO_ADMIN_PASS with Bamboo administrator password
    # replace http://localhost:8085 with Bamboo's Base URL
    # replace PROJ-PLAN with planKey that should be triggered
    curl -k -u BAMBOO_ADMIN_USER:BAMBOO_ADMIN_PASS \
         -X POST 'http://localhost:8085/rest/api/latest/queue/PROJ-PLAN'
fi

 

P.S. You must make the script executable.

 

The above script is for Linux/OS X, however, that should help you get started. You will need to make sure you use the correct system calls, etc. for Windows. To make it platform agnostic you may want to consider using Python to create the script.

 

In addition, I would also recommend you create a Suggestion on JAC to have this feature added to Bamboo. Once you do that please post the link here so others can vote on it and add impact.

 

Cheers,

Hi Branden,

Thanks for the answer. I will try that using REST APIs. As you recommended, I have created a Jira  ticket. Expecting this feature soon :)
