Vapor 不会通过 Docker 在 DigitalOcean 上构建

Question

I have a Vapor app which I'd like to deploy on DigitalOcean. The Vapor documentation suggests creating a droplet (and then setting up it manually including cloning from GitHub). But I'd like to have DC deploy my project automatically - so I created an app instead of droplet. Unfortunately it won't build:(

Here's what I see in the logs (stripped):

Could you please explain what's wrong here?

Answer 1

The Swift compiler is running out of memory and helpfully crashing without any error message. You need to compile on something that provides more memory to the build machines, either by specking it higher or using GitHub actions to build it. This is a known issue with digital ocean and Swift
