I’m trying to deploy Discourse, which uses a docker container. My app.yaml was produced using the Go yaml parser gopkg.in/yaml.v1 but I get this error when I try to start the container: Invalid containerPort: 8000520 Here’s my app.yml: http://pastebin.ubuntu.com/8329740/ Note that the strings a…

app.yml isn’t a Docker cfg file - perhaps you’re after Discourse support?

Just for posterity, I’ll post my resolution here: I figured it out, partially through using online validators that were changing the second exposed port from 2222:22 into 133342 It didn’t have anything to do with the lack of spaces before the dashes for the array (though I had several people menti…

wow. thank you very much for the update!

I was just recently bitten by this same problem and I wanted to follow up with the solution. To prevent the parser from interpreting 2222:20 as base 60, wrap it with double quotes so it is interpreted as a string. Replace 2222:22 With “2222:22”

Follow up - the go yaml parser has since been updated to make sure to put quotes around strings that could be misinterpreted as base 60, so this should never happen with yaml generated from go code… but still very possible with handwritten yaml (and possibly other parsers that aren’t 100% correct).
