Configuring the maximum and minimum heap sizes to be identical is a best practice for optimizing garbage collector performance and also helps make the JVMs footprint in RAM more deterministic. Why our builds fail While small cloud instances are typically fine for applications which are not getting a ton of traffic, there's often one factor that can be very limiting: memory . We will approach this problem from two directions, first well configure the JVM to use a deterministic amount of memory and then size a container reasonably for that limit. Fortunately, we can just set NODE_OPTIONS before running our next command. There are plenty of good written blog posts about this topic.
