I’ve been a long time admirer-er of Zeit. Besides the technical part (which is really good), their platform gives people really easy, understandable and (most importantly) trustworthy tools to get a real app into production. I’ve wanted something like this to exist for Kubernetes for a while (I even wrote about that, but I digress.)
The platform was for just Node applications for a while, but containers are a thing y’all, and Zeit lets you deploy them to its platform now (they announced it mid August). It does all the same stuff as it does for Node, but with Docker:
- Write a Dockerfile
- Run
now - Profit
There’s a ton going on there in step 2, but the basics:
- Push the Dockerfile and context up to Zeit
- Zeit does the
docker buildon their infrastructure - Zeit pushes the image to their registry (I assume they run an internal registry but no idea really)
- Zeit pulls the image into their serving infrastructure, configures it, does routing,
checks if you paid and gives you all the amazing hardware if you have and otherwise runs you on a RaspberryPiand runs your image on their servers
I mean, I’ve blogged about ACR Builds before, but this is next level. One command gives you everything.
Athens-ing it Up
There’s this rad project I know about. Something about Go and dependencies IDK but it has a Dockerfile and you can do cool stuff with it. So why not see if Zeit can handle this beast??
I had to tweak the Dockerfile a little bit because the CLI (now) doesn’t let you specify custom Dockerfile locations (I don’t think???) but that was pretty much it (check out the PR.) Now I can do this:

That’s using a multi stage build to build Athens inside a Dockerfile, on Zeit’s infrastructure. And I inception-ed it because I used a hosted Athens module proxy (update: there is now a more reliable one of these servers at https://athens.azurefd.net) to build Athens itself inside the build, on Zeit’s infrastructure.
Here’s what it looks like after it’s deployed:
➜ athens git:(zeit-now) now list
> 5 total deployments found under arschles [314ms]
> To list more deployments for an app run `now ls [app]`
app url inst # type state age
athens athens-ukiespgiyz.now.sh - DOCKER READY 4m
There’s a UI for all this on the zeit.co site too. They even stream build logs to the site too #AMAZE
Trying it Out
So basically I ran a few commands and got a ton of output on the CLI. Machines are doing my bidding; success!
Now that it’s running, I wanted to see how it performed. I started small with bld (blog post for background on that tool if you’re interested):
➜ bld git:(master) export GOPROXY=https://athens-ukiespgiyz.now.sh
➜ bld git:(master) sudo rm -r $GOPATH/pkg/mod
➜ bld git:(master) time go build

So, that kinda took a while. Building Athens itself took forever as well (about 6:30), but there are a few reasons for that, and ways to get big ole speedups from experience hosting Athens:
- Run this with more than one instance
- Hook this up to external storage
- You’d need to do this for #1 to work anyway
- This is using local disk and I have no idea what or how fast that is on Zeit
- Pre-seed the Athens cache with things
- Everything I showed was from a cold local (
$GOPATH/pkg/modfor the Gophers out there) and hosted (on the Zeit Athens server) cache
- Everything I showed was from a cold local (
All in all, this is a pretty rad platform. I give it pretty rad. Not mega rad - that’s reserved for clippy level things, but wayyy higher than semi-rad.
Keep on rockin’ everybody!
