Continuing the discussion from Please explain global scope:
based on your statement
and your intensive tests I may ask you some question about the teamwork between docker and traefik.
I’m bit confused by the statements in the docs of API and Port detection
If I look at providers overview the picture and quick start/, they tell me, that all is done by API calls and I don’t need to make any port available to other containers. In addition, it is said that containers see each other anyway, if they are in the same network but that is not that good documented you find rather
If you do not specify any of those, the service in the container will not be accessible from anywhere except from inside the container itself.
But if I read Operations → API, Docker Engine API Access and
Docker Swarm API Access, I’m not that sure anymore.
One the one hand it is said traefik provides only information via APIs but on the other hand, it also acts by means of API calls.
Moreover, port detection is explicitly mentioned in Docker Engine Port Detection and in Docker Swarm Port Detection
Any chance that someone could explain the differences in bit more details?
