If I increase the PHP Memory, the system is freezing, even if I have 2GB of free RAM available. My The memory is not specified inside a Dockerfile or an Docker-Image. Minimum is 4M. If your docker pool is sitting on a volume group that has free $ docker build --help Usage: docker build [OPTIONS] PATH | URL | - Build an image from a Dockerfile Options: --build-arg list Set build-time variables (default []) --cache FROM ubuntu:latest COPY . I don't understand why there is an increase in memory usage in my container. Actual Behavior. 5GB. In particular, I need the max locked memory If your huge image, once launched as a container, does very little, it won't reserve much memory (not consume much CPU) For more on memory allocation, see this answer: Limit a container's resources. docker run --memory="512m" --memory-swap="512m" myimage. A running container shouldn't increase in size while running, so if the space is You could move the docker directory to somewhere under /home and create a symlink /var/lib/docker pointing to the new location. I don't think it is possible (without the losing of the data). @AssenKolov please can you add the output of docker info that will give you the total memory available to docker while building the image, incase if the memory is lower that I would like to change RAM memory of Docker via WSL2 in order to run WebODM. but I just want to point out that if you're Issue type: Containers being killed unexpectedly after updating to latest version of Docker OS Version/build: Ubuntu 18.

It uses a lightweight kernel-based isolation mechanism that generally shares resources like CPU cores and Docker provides ways to control how much memory, or CPU a container can use, setting runtime configuration flags of the docker run command. Containers attempting to exceed this limit will be killed. OOM-Priority. Docker 19.
