Rundeck monitor directory

Does anyone know if Rundeck has the functionality to trigger a job upon the arrival of a file in a directory?

I've searched a bit, and it doesn't seem like I've found this feature, either in the enterprise version or in the community version.

That is an appropriate circumstance for the Waitfor Rundeck Nixy Plugin.

You may install it by going to the gear icon > plugins > locate plugins > in the "search for..." area, type "nixy" and then install the "*nixy waitfor Steps" plugin.

Now, in your workflow, you add a step to validate that, called "*nixy / waitfor / file-exist". You can provide the file path, the wait interval in seconds, and the maximum number of tries.

Check this job definition example:

- defaultTab: nodes
  description: ''
  executionEnabled: true
  id: 447af8f3-fc99-4bda-bc2d-aa91ee9c5233
  loglevel: INFO
  name: ProjectEXAMPLE
  nodeFilterEditable: false
  plugins:
    ExecutionLifecycle: null
  scheduleEnabled: true
  sequence:
    commands:
    - configuration:
        file: /home/user/Downloads/myfile
        interval: '60'
        maxtry: '2'
      nodeStep: true
      type: nixy-waitfor-file-exists
    keepgoing: false
    strategy: node-first
  uuid: 447af8f3-fc99-4bda-bc2d-aa91ee9c5233

This job waits 60 seconds for the "myfile" file on the /home/user/Downloads/ directory, if the file isn't there, it tries twice.

Alternatively, you can put a bash script logic in a script step job like this script:

#!/bin/bash

# Define the directory to monitor
directory_to_monitor="/home/user/Downloads"

# Function to monitor the directory for new files
monitor_directory() {
    # Initial list of files in the directory
    initial_files=$(ls "$directory_to_monitor")

    while true; do
        # List files in the directory
        current_files=$(ls "$directory_to_monitor")

        # Check for new files
        new_files=$(comm -13 <(echo "$initial_files") <(echo "$current_files"))

        # If new files are detected, print a message and exit
        if [ -n "$new_files" ]; then
            echo "New file detected: $new_files"
            exit 0
        fi

        # Sleep for a while before checking again
        sleep 5
    done
}

# Call the function to monitor the directory
monitor_directory

Now, the script working in a Rundeck job (the directory path is defined in an Rundeck Option).

          # Define the directory to monitor
          directory_to_monitor=@option.directory@

          # Function to monitor the directory for new files
          monitor_directory() {
              # Initial list of files in the directory
              initial_files=$(ls "$directory_to_monitor")

              while true; do
                  # List files in the directory
                  current_files=$(ls "$directory_to_monitor")

                  # Check for new files
                  new_files=$(comm -13 <(echo "$initial_files") <(echo "$current_files"))

                  # If new files are detected, print a message and exit
                  if [ -n "$new_files" ]; then
                      echo "New file detected: $new_files"
                      exit 0
                  fi

                  # Sleep for a while before checking again
                  sleep 5
