Image scan processing times out

Edit online

Image scan processing can time out when scanning large numbers of container images or images with extensive package data. Use the following steps to increase the timeout settings and rerun the discovery process.

Symptoms

You might observe one or more of the following behaviors:
  • The image scanning task does not complete successfully during auto-discovery.
  • Discovery processing fails with a timeout-related error.
  • Vulnerability and package information is not available for discovered container images.

Resolution

If image scan processing fails because a timeout limit is reached, increase the timeout values for both job execution and auto-discovery scanning.
  1. Go to Settings > Job timeouts.
  2. Update the timeout value for the applicable scan job (for example, Kubernetes Scan Job). You can specify a value between 1 and 86400 seconds.
  3. Go to Settings > Miscellaneous > Auto Discovery.
  4. Increase the Scan Timeout value.
  5. Save your changes.
  6. Rerun the discovery process.

Increasing both timeout values allows Concert more time to complete image scanning and process the results for large or complex container environments.
