fix(satellite): treat whitespace-only values as missing for required flags - #633
Conversation
…flags Trim whitespace from all string flag values before validation to ensure that whitespace-only values are treated as empty and rejected with the same error as truly missing values. This fixes the issue where values like --token=" " would pass validation silently but cause runtime issues when parsed as URLs. Fixes container-registry#624 Signed-off-by: AnouarMohamed <m.anouar@mundiapolis.ma>

It handles whitespace-aware required fields, environment token fallback, SPIFFE and BYO registry rules, default URLs, shutdown timeouts, and validation test coverage. ChangesSatellite option normalization
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The validation change can break environment-only startup by rejecting valid environment configuration and losing the registry-password fallback; some SPIFFE startup paths may also reject empty URL values before validation. These bounded configuration and startup regressions require owner follow-up before merge. Possibly related PRs

strings.TrimSpace before the fallback checks that choose environment values, so
whitespace-only CLI inputs are treated as empty and valid envCfg values are
selected. Update the token and registry-password fallback logic in the

values.

Fixes #624
This change ensures that whitespace-only values for required satellite flags (--token, --ground-control-url, --harbor-registry-url, etc.) are treated as missing values and rejected during validation.
Previously, values like
--token=" "would pass validation because they were not equal to an empty string, but would cause issues when the resulting invalid URL was parsed.Changes:
