Question

If I run the command play reload what boolean does it return if the application is not running?

If I do a deploy shell script that looks like:

play reload || nohup play start

will it start Play! if the instance wasn’t running? Or will it fail regardless?

Answer 1

To start off I had a misconception about the play reload command. It is in fact a part of the sbt tool and not the Play! application itself.

play reload returns as zero, and like Dennis Williamson pointed out it means success.

What I was actually referring to was play stage which readies the application for production in cases like an autodeployment.

Now my final deployment script looks like this:

play compile
play stop || true

nohup play -DapplyEvolutions.default=true start

Notice my handy shortcut to applying evolutions?

I’ve confirmed this works just as well and I ended up not using the play stage.
