ok solved this, just so future people see this, running the docker build script on your cheap VPS won’t work as the go binary needs a lot of RAM to run.
running the docker build script on my macbookpro and pushing it to dockerhub, then pulling it on the VPS works fine. now my caddy have vultr for wildcard lets encrypt.
That’s interesting! I’ve built Caddy binaries on my 1GB Vultr VPS’ before. I don’t recall if I tried to build them with DNS plugins.
I was going to ask if it should have been tls.dns.vultr rather than vultr, since I usually build with tls.dns.cloudflare, but if it’s working on your MBP, I guess we’re all good.
The syntax has changed for a while now if you’re using the docker image. If that still works for you, you’re probably on a version before 0.10. tls.dns.cloudflare should now be cloudfare.
