I try to use Docker and I have little problem. I don't understand why there is an increase in memory usage in my container. For example:
I have container with RabbitMQ, but it's not used. When I start the container, it has only 80Mb of memory, but after ten hours, it takes all limit (256Mb). I check statistics with docker stats -a.
Also, container has huge Block I/O
UPDATE:
RabbitMQ version 3.7.8
I used standart RabbitMQ-docker-image from docker-hub, but my server has't internet connection, and I had to use export/import.
docker export rabbitmq > /work/tmp/rabbitmq-docker-image
docker import /work/tmp/rabbitmq-docker-image rabbitmq:current
docker run -d --memory=256m --restart=on-failure --hostname rabbitmq --name prod-rabbit -p 5673:5672 -p 15673:15672 rabbitmq:current rabbitmq-server
Result of docker stats -a
