For example, to use 16GB, specify -e ES_JAVA_OPTS="-Xms16g -Xmx16g" with docker run. If the finalizer thread cannot keep up with the finalization queue, then the Java heap could fill up and an OOM could be thrown.

So there is a known pattern to avoid this, the so called immutable server. To create a trigger if your source code is in GitHub: For a complete list of flags, see the gcloud reference for how to create triggers Since Docker typically builds on top of ready-made images from a registry, you rarely have to "snapshot" the whole OS yourself. Sure you can do this with other tools, but not nearly as easily or fast. You get more isolation, but it is much heavier (requires more resources). containers are lightweight and, thus, fast, Virtuliazation achieve using software called a, Containerzation achieve using software called a Docker, Virtual machines provide virtual hardware (or hardware on which an operating system and other programs can be installed), Docker containers dont use any hardware virtualization. Guidance for localized and low latency apps on Googles hardware agnostic edge solution.
