By default, any Docker Container may consume as much of the hardware such as CPU and RAM. If you are running multiple containers on the same host you should limit how much memory they can consume.
-m "300M" --memory-swap "1G"
If you need to change the uid/gid of the user you can use:
RUN groupmod -g 999 node && usermod -u 999 -g 999 node
At the end, set the user to use when running this image
USER node
When creating an image, you can bypass the package.json's start command and bake it directly into the image itself. First off this reduces the number of processes running inside of your container. Secondly it causes exit signals such as SIGTERM and SIGINT to be received by the Node.js process instead of npm swallowing them.
CMD ["node","index.js"]

Key-Value gibi çalışan bu sistemde docker secret create [isim] [saklanacak_bilgi] komutu ile gerekli bilgiyi bir referans ismi ataması gerçekleştirerek kripte edilmiş bir vaziyette “Raft logları” arasında tutmaktadır.
