cf restage and downtime


Peter Dotchev <dotchev@...>
 

Hello,

We use some user-provided services to provide some configurations to our
apps.
Sometime we need to update the configurations but without downtime.
So we update these configs using cf update-user-provided-service command
and then we have to restage bound apps.
I have noticed that cf restage causes no downtime as it first starts the
new instances and only then stops the old ones.
This is ok for us, but I could not find any documentation of this
behaviour. Can we rely on this to stay like that in the future or would it
be better to use blue-green deployment (more manual work)?

Best regards,
Petar
