# sanad_api_x2 — AGIBOT X2 fleet agent: TELEMETRY + MAP sync.
#
# BUILD ON THE X2 COMPUTE (native arm64). There is no middleware to compile into
# the image: the state source is chosen at RUNTIME
# (X2_SOURCE=http|ros2|aimrt|none), so the image only needs whatever the chosen
# backend requires. That is what BASE_IMAGE selects:
#
#   http / none backend (default) — tiny, no ROS at all:
#       docker build -t sanad-api-x2:latest .
#
#   ros2 backend — rclpy comes from the ROS base; match the ROBOT's distro:
#       docker build --build-arg BASE_IMAGE=ros:humble-ros-base -t sanad-api-x2:latest .
#       (or ros:foxy-ros-base, ros:jazzy-ros-base, … — must match the robot, or
#        ROS 2 discovery silently fails to see the robot's topics)
#
# Run with --network host so the robot's middleware traffic is visible (ROS 2
# discovery does not cross a NAT bridge) and the agent can reach vendor APIs on
# 127.0.0.1 (the installer does this).
