How long are deploys supposed to take?

I know it depends on a lot of factors but my code is taking 1-3 minutes which is really breaking my flow and productivity. I am already a Team user for Railway (didn't seem to help at all) and I use the railway up command from the CLI to deploy. The one nuance is this server needs CGO_ENABLED but besides that I'm not understanding why it takes so long in the first place?

how big the the image when its built?

I see Pushing [==================================================>] 543.9MB 04c0d2b851c3 Pushed 04c0d2b851c3 121a47bf-47df-4e3a-a1b8-0c9888d3f770: digest: sha256:9d75f75d2f2b4621291cf91527fd96876d73a8b9a41f607ec45b19e3237ba475 size: 2633 Publish time: 38.38 seconds ==================== Starting Healthcheck ==================== Path: /healthz Retry window: 5m0s

540mb, not bad

cybershizo•8mo ago

Yeah it should be zippy

Brody•8mo ago

how long is the build time?

cybershizo•8mo ago

This one was about 3 minutes even

Brody•8mo ago

what stage took the longest?

cybershizo•8mo ago

I know the health check takes another few seconds and then it takes another 30 seconds for it to turn off the previous deploy but 3 minutes is from when I type railway up and then wait for the Starting healthcheck message How can I tell?

Brody•8mo ago

look at the logs

cybershizo•8mo ago

It's virtualized so I can't copy paste the whole thing Sec Build time: 89.75 seconds Publish time: 38.38 seconds

Brody•8mo ago

what build stage took the longest?

cybershizo•8mo ago

Are there more stages than that?

Brody•8mo ago

the build is made up of multiple stages, please look at the logs

44 seconds to go build, theres not really too many ways around that since its already cached

cybershizo•8mo ago

Based on this 8 and 12 take a ton of time I mean is it possible to get like 10 second deploys or am I oversimplifying the problem? Every time I deploy it just takes forever because I usually need multiple iterations and the feedback loop takes minutes each

Brody•8mo ago

the only thing i can see that you could improve would be the publish time

cybershizo•8mo ago

How would I improve that? Can I just build it locally and send the executable or something?

Brody•8mo ago

you would want to create your own dockerfile that uses a final image so that the published image is as small as possible, i dont have any super big go apps running on railway but the publish time of my go apps is 4-5 seconds

cybershizo•8mo ago

So I have my own docker file and I build locally? I'm open minded I just don't really know the steps

Brody•8mo ago

no, you would still let railway build from the dockerfile

cybershizo•8mo ago

I see I guess I will have to try this approach

Brody•8mo ago

personally, i stay away far away from cgo, my go build times are 10s making my total build times sub 25 seconds

cybershizo•8mo ago

Does that mean I need to have docker on my computer (Mac) or just the dockerfile and that's it? No I know it's a requirement for this one server because I needd webp I think

Brody•8mo ago

just the dockerfile, i dont have docker on my computer

cybershizo•8mo ago

Do you have an example docker file you can share? I wouldn't really know where to start And you might be right that this server in particular doesn't need CGO but one of them definitely does

Brody•8mo ago

this would be a decent starting point but would be super unlikely to work out of the box for you

what does your one server need cgo for?

cybershizo•8mo ago

One of the thing this machine does is convert PNG to WebP But only one server needs that

Brody•8mo ago

that needs cgo?

cybershizo•8mo ago

Yes because nobody writes WebP encoders They just talk to the C library because it's too complicated to rewrite the lib

Brody•8mo ago

theres no pure go to webp encoder?

cybershizo•8mo ago

No so far that I can find Apparently it's wildly complicated

Brody•8mo ago

fair enough

cybershizo•8mo ago

What is this bit about? FROM gcr.io/distroless/static

Brody•8mo ago

i copy the built binary into the distroless image so that the final image is nearly as small as the binary itself

cybershizo•8mo ago

OK I see. I'll play with docker deploys later and see if I can remove CGO from one of my servers

Brody•8mo ago

resulting in sub 10mb images for me, and thats how i get my 4 second publish times

Great thanks, that helps for now. Have two things I can try Yeah 1-3 minutes is killing me I'll mark this as solved, thanks @Brody
