Hey, so the 502 is coming from the Gateway which delegates the deployment to the Nomad provider. The gateway is returning a 502 because the provider has reported a problem when trying to start the function but it is not returning why.

If you look at the logs for the Nomad provider docker logs [faas-nomad id] this should give more info, could you also give the latest provider a go v0.2.22. I know the gateway changed the way that deployments happened which I fixed in version v0.2.22 however I can't remember which gateway version it was either .14 or .15

Good luck.. would be curious to find out what's in the log too. Nic we have 0.7.0 of the gateway available now with some performance improvements.

@nicholasjackson thanks for the quick response! I can confirm faas-cli worked with version 0.2.22 of faas-nomad and gateway 0.6.14. However the log output of nomad logs [alloc-id] nomadd only logs the following at startup and then nothing more:

2018-02-15T10:09:48.594Z [INFO ] nomadd: Using StatsD server:10.48.4.59:9125 2018-02-15T10:09:48.594Z [INFO ] nomadd: Started version: 0.2.22

I think it logs the main output to StdErr, glad you got this working, there was an update in the gateway which added support for rolling updates which is super cool. I had to add a new handler to the Nomad provider. I will give 0.7.0 a test with the latest provider tonight and if all is well, will update the default job files.
