Contour models its configuration using a directed acyclic graph (DAG) of internal objects.
This can be visualized through a debug endpoint that outputs the DAG in DOT format.
To visualize the graph, you must have
graphviz installed on your system.
To download the graph and save it as a PNG:
# Port forward into the contour pod $ CONTOUR_POD=$(kubectl -n projectcontour get pod -l app=contour -o name | head -1) # Do the port forward to that pod $ kubectl -n projectcontour port-forward $CONTOUR_POD 6060 # Download and store the DAG in png format $ curl localhost:6060/debug/dag | dot -T png > contour-dag.png
The following is an example of a DAG that maps
