marathon app update documentation misleading (requires file)

[ryansydnor]

The cli documentation states:

dcos marathon app update [--force] [...]

However, the update command cannot simply accept a json string as indicated but rather requires piping to it.

For example,

dcos marathon app update basic-0 '{"instances":100}' will fail.

These will succeed:

echo '{"instances" : 100}' | dcos marathon app update basic-0
dcos marathon app update basic-0 < config.json

Hi @SL4YT1M3 !

This seems to be related to the dcos-cli and not to Marathon itself.

Could you post your issue in this repository again?

Thank you very much.

This syntax works without piping:
dcos marathon app update --force basic-0 instances=5

See https://docs.mesosphere.com/using/cli/marathonsyntax/ for more examples.
