I am going to discuss about the solutions which I found in my experience. Lets run the app again with the memory limited to 384MiB: after running a few thousand requests through each of these services, docker stats shows: The limit-heap-and-container container is using 308MiB of its 384MiB limit (80%). The same container is running fine with the root user. this case, containers) are using excess memory. And imported shared module in other modules where ever it is applicable. This kind of problem, I solved by adding a swap file to the machine to help a bit the memory (Maybe this article can help you: https://tecadmin.net/linux-create-swap/) and, setup this env ENV NODE_OPTIONS=--max_old_space_size=2048 in your Dockerfile to limit the memory will be used by the node process. You also need the, The maximum realtime priority allowed for the container. You can see how weve done that in the following example: From the example shown above, we started from one GB and continued until we increased the memory to four GB. To summarize it, most of the memory leaks can be traced back to not removing all references to objects that you don't need anymore. --max-old-space-size= We would have to run something along the lines of node --max-old-space-size=4096 index.js. Therefore, for simple cases where I don't want to use additional external services to build an application, I've set up a script which is called from a git-hook: While the process explained above is probably the easiest way without any additional services and installations, there are alternatives providing advantages at the cost of complexity. Actualy the result is quite comparabile to what you get when you set -XX:+ UseContainerSupport in Java 11 or later. This greatly simplifies the task of finding hosts with sufficient resources and running those hosts at high utilization, all while achieving other operational goals such as always running applications fully in RAM, avoiding swap memory. You need to My personal suggestion is that try to avoid using external libraries as much as possible. By default, a container has no resource constraints and can use as much of a container can use 300m of memory and 700m (1g - 300m) swap. Try reducing the number of cores. Which is the equivalent to manually specifying --cpu-period and --cpu-quota; You can configure your container to use the realtime scheduler, for tasks which Swap is slower and I am running a container in EKS Fargate. To learn more, see our tips on writing great answers. Using an external build server: Not the answer you're looking for? where.
