How can I speed up my build time?

Each build takes roughly like 4 minutes. I'm testing on prod so it makes my iterations kinda slow.

Solution:

nope, please look into multi layered dockerfiles

how big is the image? also why compile and minify your .ts file? bun has first class support for ts

HarrisOP•7mo ago

because this is production and that's much more performant

Brody•7mo ago

how long does that specific command take when building?

HarrisOP•7mo ago

100ms

HarrisOP•7mo ago

Brody•7mo ago

how long does railway say it took

HarrisOP•7mo ago

the docker file itself is finished in 12s

HarrisOP•7mo ago

but the image is quite big idk why

Brody•7mo ago

yes, how big keep in mind i cant read your logs for you

HarrisOP•7mo ago

1 layer = 99.96MB another layer = 715.2MB

HarrisOP•7mo ago

even then it says it only taks 124s tho

Brody•7mo ago

thats big, do you need node during the runtime?

HarrisOP•7mo ago

not after i've compiled the executable from bun, i don't think i need anything at that point

Brody•7mo ago

big images take a seemingly exponentially longer time to deploy and there is some awsome fixes in the pipeline for that but until then, the only fix would be to write a better dockerfile

HarrisOP•7mo ago

can I clear the entire image after i compile the executable?

Brody•7mo ago

in more words, yes, you will want to look into multi layered images

HarrisOP•7mo ago

oh wait, yeah, that makes sense the executable is the 700mb it's every package

Brody•7mo ago

you are like 10% of the way there with -

FROM oven/bun:1 as base

FROM oven/bun:1 as base

HarrisOP•7mo ago

yeah but if I'm making an executable each time it'll be different so you can't save it as layers so i just have to tank the performance hit i thikn

Solution

Brody•7mo ago

nope, please look into multi layered dockerfiles

HarrisOP•7mo ago

how do i do a multi-layered dockerfile with a binary executable? since it itself will alwasy be ~700mb and changing

Brody•7mo ago

FROM oven/bun:1 AS builder

// install node and do build stuff

FROM oven/bun:1

// only copy the needed stuff down

// start the server

FROM oven/bun:1 AS builder

// install node and do build stuff

FROM oven/bun:1

// only copy the needed stuff down

// start the server

get the idea?

HarrisOP•7mo ago

while i agree that will help, I don't think that solves the core issue i think the biggest time sink is that the 700mb executable is being uploaded every time the build step itself doesn't take that long

Brody•7mo ago

are we talking about the node executable?

HarrisOP•7mo ago

no, the bun compiled executable of my server

Brody•7mo ago

its actually 700mb?? where is this number coming from?

HarrisOP•7mo ago

no the compiled executable is only 70mb, idk where the rest is coming from hvaen't dug into it yet

Brody•7mo ago

then it's coming from node and everything else in the image that isn't needed ^ ^
