01:22 <rwilliams[m]> I'm using jruby with Docker/Docker compose and I'm wondering where to stick the "--dev" flag

01:23 <Jyrki[m]> you can set it in the `JRUBY_OPTS` environment variable, at least that's what I tend to do...

01:23 <rwilliams[m]> so something like web:

01:23 <rwilliams[m]> environment:

01:23 <rwilliams[m]> - JRUBY_OPTS="--dev"

01:24 <Jyrki[m]> yep (or whatever the syntax for docker-compose is)

01:24 <rwilliams[m]> gotcha

01:24 <rwilliams[m]> i'll give that a whirle

01:30 <rwilliams[m]> Hmm I get "Error: Could not find or load main class "-Xcompile.invokedynamic=false"

01:31 <rwilliams[m]> When i try to run rails routes

02:28 <rwilliams[m]> So rails routes with --dev "rails routes 18.97s user 4.24s system 155% cpu 14.929 total" It's like 22s without --dev. Is this normal? Also i tried drip and theine with out getting either to work.

02:32 <rwilliams[m]> I also noticed rbenv uses Java Hotspot and the official jruby docker image uses OpenJDK, is this why the ---dev flag fails on the docker image?

04:28 <headius[m]> Shouldn't make any difference there

04:29 <headius[m]> You are seeing those times on what kind of system?

04:29 <rwilliams[m]> Ubuntu 18.04 on WSL2

04:29 <headius[m]> The error you got about invokedynamic would mean it was passed to the Java command, not to JRuby

04:29 <headius[m]> Hmmm ok wsl, I have not tried that myself yet

04:30 <rwilliams[m]> WSL2 actually has a full linux kernel and seems pretty fast for everything else

04:31 <headius[m]> It does seem rather long, but I know many rails commands launch twice which can aggravate startup impact

04:31 <headius[m]> Did you put it in env JRUBY_OPTS?

04:32 <rwilliams[m]> yeah

04:47 <rwilliams[m]> I guess i messed up the JRUBY_OPTS the first time around in my docker-compose. Now that it's working with --dev it takes 24 seconds for 'rails routes' via docker and it was 14 seconds when i ran it locally.
