# Removing public key for security purposes. # Paste the output in your destination servers' ~/.ssh/authorized_keys file: Let's call it SyncFiles: mkdir /opt/syncfilesĪnd for secure file transfer, we want a public-private key link for the transfer link that rsync uses, this is how to configure it: ssh-keygen -t rsa -f ~/rsync-key -N '' Backup/failover servers with the need for constant replicationįirst things first: we need to get all the dependencies installed on the 3 servers with this one-line command: apt update & apt -y install openssh-server rsync inotify-toolsĪfter that, let's create a specific folder that we want to sync.Load balanced file storage clusters/servers.A development environment, where constant file transfers are taking up a lot and/or too much time.I could see some potential for workflow improvement on these situations: All rsync traffic is supposed to be worked out over SFTP. All these 3 machines needed to be setup with the following software packages:Īlso noteworthy is that these machines are absolutely not connected through a private network. I needed to get myself a nice development environment at first so I started off 3 virtual servers which all run Ubuntu 16.04, my personal favourite. Rsync is a great solution, but having to run rsync manually would take a lot of unnecessary time away, right? And that is where inotify is for: real-time monitoring of your filesystem so that your files can be synced between multiple machines with the power of rsync! Well, I got the solution for you: with a little bit of thinking in an innovative way I have found the solution that might bring you onto the right path as well. They contain files that you want to have automatically synced when possible, because that would save a lot of time. So: you've got two or more clients and/or servers. The current code does not work with Pipeline projects ( JENKINS-48239).Sync folders and files on Linux with rsync and inotify Therefore, we recommend to not use FSTrigger plugin when you want to poll a directory with a large set of files. For example, we can't get similar performance as with Python. The current code is written in Java and it is not very optimized. If you want just to know if a set of files exists and display the number of files found, you can use Files Found Trigger plugin. 'jobB' may provide packaging steps, testing steps or other steps of a pipeline.īoth jobs are independents and listen external events. If there is a change, 'jobB' is scheduled. A second job 'jobB' checks the existance of the new artifacts in the target filesystem.) and deploys these artifacts in a target filesystem. The build instantiates a build process, produces artifacts (binaries, text output. A first job 'jobA' polls a SCM tool and schedules a build if there is at least one change.Avoiding explicit jobs dependencies (with upstream/downstream mechanisms) Scheduling a build if the last modification date of a file has changed compared to the last modification file date captured in the previous pollingģ. ![]() Scheduling a build if a specified file is found in a folder and was not present in the previous buildĢ. the presence of a pattern in a text file (such as a log file)ġ.the modification of an attribute (or all attributes) in a source MANIFEST.NF.the modification of an attribute (or all attributes) in the MANIFEST.NF of a JAR file.the modification of a property (or all properties) in a properties file.the modification of the structure or the content in a TAR file.the modification of the structure or the content in a JAR or in ZIP file.the modification of values from XPath expressions in an XML file.the full content in a file (whatever the file type).The last modification date of the file has changed compared to the previous pollingįor the latest choice, the content file detection can be:.The file no longer exists whereas it existed in the previous polling.The file exists and it didn't exist in the previous polling.The file path can be provided either explicitly or with a GLOB. ![]() the content of at least one file has changedįor the second use case, we monitor a file from a path.the last modified date of at least one file has changed.1) Polling a set of files in a folderįor the first use case, we trigger a build if the list of files has changed between 2 pollings:Ī build is triggered in the following situations: ![]() This plugin provides a polling typology among the XTrigger Plugin. There is no impact on the Jenkins infrastructure (no new files created). Note: The plug-in uses only persistence in memory. The plug-in makes it possible to monitor changes of a file or a set of files in a folder. Filesystem Trigger Plugin (also known as FSTrigger) provides polling mechanisms to monitor a file system and trigger a build if a file or a set of files have changed.
