Bacalhau has two ways to make use of external storage providers: Sources and Publishers. Sources are storage resources consumed as inputs to jobs. And Publishers are storage resources created with the results of jobs.
Bacalhau allows you to use S3 or any S3-compatible storage service as an input source. Users can specify files or entire prefixes stored in S3 buckets to be fetched and mounted directly into the job execution environment. This capability ensures that your jobs have immediate access to the necessary data. See the for more details.
To use the S3 source, you will have to specify the mandatory name of the S3 bucket and the optional parameters Key, Filter, Region, Endpoint, VersionID and ChechsumSHA256.
Below is an example of how to define an S3 input source in YAML format:
Bacalhau's S3 Publisher provides users with a secure and efficient method to publish job results to any S3-compatible storage service. To use an S3 publisher you will have to specify required parameters Bucket and Key and optional parameters Region, Endpoint, VersionID, ChecksumSHA256. See the for more details.
Here’s an example of the part of the declarative job description that outlines the process of using the S3 Publisher with Bacalhau:
The Local input source allows Bacalhau jobs to access files and directories that are already present on the compute node. This is especially useful for utilizing locally stored datasets, configuration files, logs, or other necessary resources without the need to fetch them from a remote source, ensuring faster job initialization and execution. See the for more details.
The URL Input Source provides a straightforward method for Bacalhau jobs to access and incorporate data available over HTTP/HTTPS. By specifying a URL, users can ensure the required data, whether a single file or a web page content, is retrieved and prepared in the job's execution environment, enabling direct and efficient data utilization.
