public_base_image_exists: Check if a public base image exists (anonymously)
In starburst: Seamless AWS Cloud Bursting for Parallel R Workloads
public_base_image_exists R Documentation
Check if a public base image exists (anonymously)
Description
Public ECR images are world-readable, so we can probe the manifest without
credentials via 'docker manifest inspect'. Returns FALSE on any error (Docker
missing, network issue, tag absent) so callers fall back to a private build.
Usage
public_base_image_exists(image_uri)
Arguments
image_uri
Full public image reference, e.g.
public.ecr.aws/f8g1e7l5/base:r4.6.1.
Value
TRUE if the manifest is retrievable, FALSE otherwise.
