NLnetLabs-krill/.github/workflows/e2e.yml

# This workflow deploys Krill and various Relying Parties (such as Routinator)
# in a local Docker private network and verifies that, for example, ROAs
# published by Krill can be retrieved by the RPs.
#
# 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
# cloud deployment involved.
#
# Commit 9a88f9c is the last version of this workflow that was configured to
# use cloud deployment.
#
# 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
# terraform/krill-e2e-test subdirectory.
