+# This workflow deploys Krill and various Relying Parties (such as Routinator)

+# This test was originally designed to work on remote cloud VMs such as
+# DigitalOcean or Amazon Web  Services as the GitHub Runner hosts were too
+# small. However, the test now  works on GH Runners, but for historical reasons
+# the test is still orchestrated by Terraform even though there is no longer any

+# Commit 9a88f9c is the last version of this workflow that was configured to

+# The actual E2E test framework is not part of the Krill repository as it is
+# quite big. The framework is at https://github.com/NLnetLabs/rpki-deploy in the
