catalogue-agent and approvisionnement-agent named a Deployment, a Service, an Ingress and a Certificate in French, in an estate where nothing else is. The peer URLs move with them, set through the existing per-environment override so the rename takes effect without rebuilding an image; the defaults in the code carry the same values for the next build. The Keycloak client ids, the image names and the repository names are still French. They are a separate, heavier move. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Reaching this agent from outside the cluster.
|
|
#
|
|
# Until now nothing did: an agent answered only what could call its Service, so
|
|
# every conversation with it went through `kubectl run curl`. An orchestrator
|
|
# nobody can talk to is not finished.
|
|
#
|
|
# Peer traffic does **not** come through here — approvisionnement calls, and is called by,
|
|
# other agents on their in-cluster Service names. This is the human door.
|
|
#
|
|
# ## It is not an open door
|
|
#
|
|
# A2A carries the end user's token in `Authorization`, and this agent forwards it
|
|
# and exchanges it; a forged one fails at the realm. But "fails downstream" is
|
|
# not the same as "refused", and an unauthenticated caller could still make the
|
|
# agent do work — inference costs money and a request that reaches an LLM is a
|
|
# prompt-injection surface. So the same authentication subrequest that guards the
|
|
# n8n endpoints guards this one: Keycloak's userinfo answers 200 for a valid
|
|
# bearer in the realm and 401 otherwise, which is the auth-request contract
|
|
# exactly.
|
|
#
|
|
# It authenticates, it does not authorise. What the caller may actually reach is
|
|
# decided further down, by the exchange and by the roles in their token.
|
|
#
|
|
# **The agent card is behind it too.** A2A discovery is normally public; here it
|
|
# is not, because a client that cannot send an `Authorization` header cannot use
|
|
# the agent anyway, and the card names the skills.
