Spring Cloud DataFlow shell command "not currently available"

Question

I sometimes get this error:

2016-10-20T15:38:24+0200 WARN main o.s.s.c.SimpleParser:131 - Command 'app register --name email --type source --uri <uriToMyDockerImage>' was found but is not currently available (type 'help' then ENTER to learn about this command)

At other times it works as expected.

Note that I start the shell with --dataflow.uri=<url> --spring.shell.commandFile=<path>.

Why would the app register command not be available? What can I do to make it available?

This would happen if the last time the server tried to connect to the REST API of the dataflow server, the server was down. This happens at

shell start
everytime you do dataflow config server <url>

@eric: perhaps you meant to add: `dataflow config server ` :) – Sabby Anandan Oct 21 '16 at 17:18
I start the shell with `--dataflow.uri= --spring.shell.commandFile=`. – Remon Sinnema Oct 24 '16 at 08:28
@eric: I guess the first "server" should be "shell"? – Remon Sinnema Oct 24 '16 at 08:29
no, it's really "shell": at shell start, the shell tries to connect to the default server URL (http://localhost:9393). I hope this makes sense – ebottard Dec 04 '16 at 08:48
Sometimes it takes the SCDF server a while (e.g. over 30 seconds) to become responsive. This is _after_ Kubernetes reports it as `Ready`. Waiting until the SCDF server responds before starting the shell fixes the issue. – Remon Sinnema Dec 12 '16 at 10:42
