-At the end of your test pull, Docker offers a suggestion to use Docker Scout to examine your image for vulnerabilities (see red box above). Since you will want to use Docker Scout to evaluate your custom build later, now is a convenient time to test this tool and make sure you are fully set up to run Docker Scout (even though we do not expect the base images to have any security problems).

Since you will want to use Docker Scout to evaluate your custom build later, now is a convenient time to test this tool and make sure you are fully set up to run Docker Scout. Although we do not expect the base images to have any security problems, it's most efficient to run this quick check before you spend time building on this image, in case it has accumulated a vulnerability since we last scanned it.

 ### **A note about security and expiration of approved Docker images**
 
-Because of the ever-updating nature of vulnerability detection, an image that has passed in the past is not guaranteed to always pass. Even if you are resumitting an image that has passed previously, there may be new vulnerabilities that have been reported that mean the image does not pass now. Best practices for most efficient submission are to always [examine an image with Docker Scout](nextflow-create-docker.md/#run-docker-scout) before pushing it.

 Similarly, because new vulnerabilities are always emerging, to protect the security of the Gen3 Workspace, approved containers will only remain available in the approved repo for 30 days. However, users can always request new credentials and resubmit their image for scanning.
