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. What we can be sure of at this point is that the JVM or any other process running inside the limit-heap-and-container will only be able to use up to a maximum of 384MiB of RAM. In such a scenario, we can use the following ways to prevent the problem. 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. users do not need to change these values from their defaults.
