Jobman automates the process of running and monitoring jobs on the command line. Jobman supports * running commands in the background immune to hangups * retrying commands * aborting commands after a timeout period * logging command output * sending notifications on command success or failure * delaying command execution for a specified time or event

Documentation

Visit the :book: jobman documentation site :book: for complete information on using jobman.

For package implementation details, see the jobman page in the Go reference.

Example

The example below uses jobman to run a Python script train.py in the background and immune to hangups (e.g., a SIGHUP from an SHH timeout).

Jobman will ensure 60 seconds have passed and that the file data.csv exists before starting the program. If those conditions haven't been met by 5:00PM on March 5, 2032, jobman will abort the job.

Jobman will retry the program up to five times until there's one successful run, defined as an exit code of 0 or 42, waiting ten seconds between retries.

If the job succeeds, jobman will send a notification email. If the job fails, jobman will send an SMS message. bash jobman \ -wait.timedelta 60s -wait.file data.csv -wait.abort-datetime "2032-03-05T17:00:00" \ -retries.num-successes 1 -retries.num-runs 5 -retries.success-codes 0,42 -retries.delay 10s \ -notify.on-success my-email -notify.on-failure my-cell \ train.py

After submitting the train.py job above, use jobman show to display details on job progress: bash jobman show train.py

To view a running log of the consolidated stdout and stderr streams of the latest run of the train.py job, use jobman logs: bash jobman logs train.py -follow

Installation

There are multiple ways to install jobman. The recommended method is to use the RPM, deb, or apk package, if applicable, or a precompiled binary otherwise.

Package manager packages

Jobman is available via RPM, deb, and apk packages as jobman_<version>-_linux_(amd64|386).(rpm|deb|apk). Download packages for the latest jobman version from the latest releases page on the GitHub repository.

Precompiled binaries

Precompiled binaries are available for Linux, MacOS, and Windows as jobman_(Linux|Darwin|Windows)_<(x86_64|i386)>.tar.gz. Download binaries for the latest jobman version from the latest releases page on the GitHub repository.

Docker image

Use docker run to pull and run the latest jobman Docker image from Docker Hub: bash docker run -it jobman

To build the Docker image locally instead of pulling from Docker Hub, use the docker-image make target: bash make docker-image

Build from source

Building jobman from source code requires Go version 1.15 or greater.

Start by cloning the repository: bash git clone https://github.com/ryancswallace/jobman.git cd jobman

Then build and install the jobman binary under your GOPATH using make: bash make install

The Makefile provides several other targets for convenience while developing, including: * format: formats the source code * test: runs the jobman test suite, including unit tests, end-to-end tests, performance tests, and linters * build: builds the jobman binary for the current platform

Alternatives

Jobman aims to be reliable and fully-featured. It operates without requiring a system service/daemon for orchestration.
