Is it possible to run elastic on 1 GB of RAM for testing purposes?


I have a dev box with low memory and so far I've been unable to start elastic search.
Is there a way to lower the heap memory required and still be functional for dev purposes?

You can lower the heap elasticsearch allocates in the jvm.options file. If
you use the rpm or deb it is in /etc/elasticsearch. Find the -Xms and -Xmx
lines and make them -Xms256mb and -Xmx256mb. Any lower than that and I
expect things to not work so well. Any higher than that and you are really
starving the disk cache.


Thanks I tried that and it at least didn't get killed immediately. Still didn't get it fully started I think I might need to stop some other running applications and free up some swap space.

Either way though thanks for the solution it does work I just have too many things running on my Dev box.
