Client: Print Last Error After Rekor Retires Fail #2640
Description
Description
When the Rekor client retries requests (ex: adding a record to the transparency log), in many common situations it does not print a detailed explanation for the error. An example output from a Rekor instance that was experiencing degraded performance:
Error: signing quay.io/<image-repo>/<image-name>@sha256:<image-digest>: Post "https://<rekor-url>/api/v1/log/entries": POST https://<rekor-url>/api/v1/log/entries giving up after 4 attempt(s)
error during command execution: signing quay.io/<image-repo>/<image-name>@sha256:<image-digest>: Post "https://<rekor-url>/api/v1/log/entries": POST https://<rekor-url>/api/v1/log/entries giving up after 4 attempt(s)
Printing the "last error" would help end users understand what went wrong and take appropriate action.
