Deploying Server-Side Swift Apps with Docker | Ray Wenderlich

This is a companion discussion topic for the original entry at

I enjoyed your presentation (almost two years later) and I’m trying to follow along and getting errors. Is there an updated version of the files?

@chriscrossen What errors do you get exactly?

@shogunkaramazov I trashed the files. I’ll re-create it and post my results.

The first problem I ran into was running the Swift REPL from Docker:

Chriss-iMac:~ chriscrossen$ docker run --cap-add sys_ptrace -it swift bash

I resolved this by using:
docker run --privileged -it swift bash

In trying to run the TIL app under Docker using:
docker build -t webapp .
I have a very long console log which I saved. The end of it is:

/usr/bin/ error: cannot find -lCOpenSSL
. . . (many of these same lines)
/usr/bin/ error: cannot find -lCOpenSSL
clang: error: linker command failed with exit code 1 (use -v to see invocation)
:0: error: link command failed with exit code 1 (use -v to see invocation)
error: terminated(1): /usr/bin/swift-build-tool -f /var/www/til/.build/release.yaml main output:

The command ‘/bin/sh -c swift build --configuration release’ returned a non-zero code: 1

@chriscrossen Do you still have issues with this?

It still does not work (as documented in my previous post), but I have given up on this and am working my way through the book ‘Server Side Swift with Kitura’.
