@kwladyka I'd try to restrict docker container running on your local host to 60 MB or something like that and see if it still works. When I tried a simple app I couldn't get it work on less than ~130 MB. JVM process consumes much more than just heap memory (see my SO answer with very useful links: https://stackoverflow.com/questions/62303368/accounting-for-java-memory-consumption/62307787#62307787) - e.g. during startup Clojure apps tend to load lots of classes and thus Metaspace consumption will be likely at least 20-30 MB. I didn't notice if you mentioned what JDK you're using and if you tune heap size - see XX:MaxRAMPercentage in particular (70% as mentioned by @lukaszkorecki is a good value in my experience) To sum up: to run anything in prod I'd give it at least 256 MB of ram

yes, I wanted to try also Metaspace limits, BUT I can’t understand why the same image work on my localhost with 128M and not in google cloud run with 128M or even 256M, it needs 512M

Why use XX:MaxRAMPercentage vs let java (new ver. like 11 / 14 / 15) do what it want?
