Generate schema by annotated entities without DB connection

[scapital]

Is it possible generate schema only use info form entity, not to load actual schema from DB?

Problem:
I use "cycle/orm and co" among with symfony. Schema is compiled while cache:clear, cache:clear is run while docker build.
As there is no db connection, this error occur.

[PDOException (7)]
SQLSTATE[08006] [7] could not translate host name "db" to address: Name does not resolve

As a workaround, I do cache:clear at startup time.
But it loads DB, every kubernetes pod get schema from DB at the same time.

Looks like a good feature request.
We'll discuss it. Btw I recommend to store ORM schema as a PHP file in git.

Yes, I though about it. Trigger re-generate schema just after migration:(up|down) is finished.
For small-size team it will work, but for mid+, a lot of git conflict while merge can be a really annoying.
