Introduction to a Job

TrueFoundry jobs enable you to run task-oriented workloads which are meant to run for a certain duration to complete a task, then terminate and release the resources.

Here are some scenarios where Jobs are particularly well-suited:

Model Training: Train machine learning models on large datasets, where the resource gets freed up once the training is complete.
Maintenance and Cleanup: Schedule routine maintenance tasks, such as data backups, model retraining, report generation etc.
Batch Inference: Perform large-scale batch inference tasks, such as processing large volumes of data using trained models, leveraging Job's ability to handle parallel workloads efficiently.

Key considerations when building a Job

We need to consider the following things while deploying jobs:

Dockerize the code to be deployed.
Schedule Job to specify when the Job should run.
Define the resources requirements for your service - Define Resources - While the documentation is specific for services, its the same as what is required for jobs.
Parameterize a job to enable ease of changing argument values.
[Optional] Defining environment variables and secrets to be injected into the code - Environment Variables and Secrets.
Set retries and timeout for your jobs in case the job gets stuck or fails for some reason.
[Optional] Set Concurrency Limit to specify how many instances of a Job can run at once.
[Optional] Mount files or volumes to your job - Mount File or Volumes.
Access data from S3 or other clouds
Update, Rollback, Promote your Job: While the documentation is specifically for Services, the Update, Rollback, and Promote process follows a similar flow for Jobs.
Setting up CI/CD for your Job: While the documentation is specifically for Services, the CI/CD setup process follows a similar flow for Jobs.

Running your First Job:
