# Warp as a Complement homeserver image.
#
# Complement (https://github.com/matrix-org/complement) is the official
# Matrix integration suite: it runs one container per homeserver per test and
# drives it over the real HTTP API. Its image contract is short, and this
# file exists to meet it:
#
#   - EXPOSE 8008 (client) and 8448 (federation).
#   - Take the server name from the SERVER_NAME environment variable.
#   - Keep storage inside the container.
#   - Survive the entrypoint being run more than once.
#   - Answer GET /_matrix/client/versions with a 200.
#
# Build it from the repository root, because the build context is the Go
# module one directory up:
#
#   docker build -t complement-warp -f server/test/complement/Dockerfile .
#
# Federation (port 8448, served over TLS with a certificate signed by the CA
# Complement mounts at /complement/ca) arrives in Phase 5. Until then this
# image is for the federation=off profile: the C-S tests. The port is still
# exposed, because Complement expects it to be.
