Add optional flag, so container is not starting with all "fig up", but only on manual demand

[sielaq]

It would be awesome to have "optional: true" in fig.yml,
so container is not starting with when "fig up" / "fig up -d" is executed.
but only when you do "fig up " / "fig up -d "
It sould not affect current config so default is "optional: false"

Then you can have multiple versions / alternative solutions /
some specific containers for specific purposes, that are not starting by default.

I think this relates to, or is a dup of #630 (and related issues)

hmm you mean initial_scale: 0 or scale: 0
sound like a good alternative

[sielaq]

but with second thought it is not a goog idea with scaling - then manual run would overrive scale option ?
What if optional container also need to be scaled?

[thaJeztah]

Good point, not sure. I think right now you would be able to do fig up -d <service-a> <service-b> .... to only start those services. But this can be cumbersome for a large amount of services :D
