Fixes

  • 🐛 Make volume mount names RFC1123 DNS label strict (#3740)

    Fixed a bug where a secret name with dots (e.g. gcr.io) led to a TaskRun creation failure, because the secret name was used internally as part of a volume mount name. These volume mount name have the be RFC1123 DNS label conform and therefore disallow dots as part of the name.

  • 🐛 Fix bug where step status ordering did not match step container ordering (#3679)

  • 🐛 set task as failed (#3571)
