Combine the container ID with the path to your system's control groups directory. Outside of container, I could access memory usage by command: docker stats <container_id> --format "{{.MemPerc . Use volumes | Docker Documentation Java and Docker, the limitations - royvanrijn I have a problem to solve: A container is running a python program, and I would like this python program to detect the memory usage of docker container running itself. Theoretically, in case of a java application. Patterns for running tests inside a Docker container Docker Misleading Containers Memory Usage Then you can inspect the pseudo-filesystem to find detailed resource stats. Run the docker stats command to display the status of your containers.
