I want a container to share PID with host OS and I found host pid mode in docker options.
However, It seems not to support in swarm mode as my testing though I check it works on docker run and docker-compose up.
In the document, there is no mention that swarm mode doesn’t support host pid mode.
Swam mode doesn’t support host pid mode?
Actually, I posted this topic on stack overflow first but I couldn’t have gotten an answer.
This is my full asking on stack overflow.
