I was looking into running a UDP service on the flexible environment.
Unfortunately, I'm running into some roadblocks. I read the guide here on
how to setup port
forwarding:
https://cloud.google.com/appengine/docs/flexible/custom-runtimes/configuring-your-app-with-app-yaml#runtime-environment.
It appears to be in the syntax of Docker forwards, and if you'd like Docker
to forward udp you must forward a port like
${OUTSIDE_PORT}:${INSIDE_PORT}/udp. When I try to do this, I get the
following error:
Updating service [default]...failed.
*ERROR:* (gcloud.preview.app.deploy) Error Response: [400] The validation
strategy encountered errors
Details: [
[
{
"@type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"description": "Value \"53:5353/udp\" does not match the pattern
\"^(?:[0-9]+(:[0-9]+)?)$\"",
"field": "version.network.forwarded_ports[0]"
}
]
}
]
]
Any ideas?
