Jobs - Concepts

Container image

A container image is a file that includes all the requirements and instructions of a complete and executable version of an application. When running a job, the selected image will be pulled to execute your workload. Images can come from public external registries or from the Scaleway Container Registry.

Environment variables

An environment variable is a variable whose value is set outside the program, typically through functionality built into the operating system. An environment variable is made up of a name/value pair, and any number may be created and available for reference at a point in time.

Ephemeral storage

In addition to CPU and RAM, Serverless Jobs also provide a storage volume for the duration of the task. This storage space allows to hold the data retrieved by the job, and disappears once the execution is complete.

GB-s

Unit used to measure the resource consumption of a container. It reflects the amount of memory consumed over time.

Job

Serverless Jobs is a fully managed solution that enables you to plan, schedule, queue and run batch processing workloads without worrying about provisioning and scaling. A job is a single instance of one of these batch processing workloads.

Job definition

A Job definition is a template for a Serverless Job. It contains all the information necessary to run the job, including the container image used, the resources allocated, and the command to execute. The definition acts as a blueprint for job runs.

Job name

The name of a job is part of the job definition and is used for informational purposes only.

Job run

A job run is the execution of a job definition. It can be in a running, succeeded, canceled, or failed status. Each job run has a unique identifier and can be individually monitored using Cockpit.

Maximum duration

The maximum duration option allows you to define the maximum execution time before your job is automatically killed.

Schedule (cron)

A schedule (cron) is a mechanism used to automatically start a Serverless Job at a specific time on a recurring schedule. It works similarly to a traditional Linux cron job, using the * * * * * format. Refer to our cron schedules reference for more information.

Startup command

This optional field allows you to specify a custom command executed upon starting your job if your container image does not have one already, or if you use a public container image.

vCPU-s

Unit used to measure the resource consumption of a container. It reflects the amount of vCPU used over time.
