Example in the FAQ implies that manifest name is not strict, however manifests seem to need to be called codius.json according to this error:
$ codius upload manifest.json
⚠ Hosts will NOT be added to the HOSTS env in the generated manifest.

2019-04-01T21:49:20.471Z codius-cli:uploadhandler error Codius File
/Users/{me}/Desktop/Code/examples/nginx/codius.json
does not exists please add a codius.json file.
I suggest changing the last line from:
codius upload /tmp/example-manifest.json --host https://host1.codius.live --duration 200
to:
codius upload /tmp/example/codius.json --host https://host1.codius.live --duration 200
