Re: Documents about multiple app ports


Mike Youngstrom
 

I don't think that the thought was that Container Networking would provide
externally facing ports. But both needed a way to tell an application to
add a listening port each app instance container. One would be routed to
from routers and the other directly. Conceptually they could be similar.
The only difference being one gets an external route mapped to it and the
other doesn't.

That said I think container networking is moving towards maturity. So, I'd
like to see the discussion and work started again soon as well.

Thank you Mike for telling me the story I didn't know.

It's OK if the multiple app ports feature will or may be supported in the
container networking.
#But I don't know if the container networking can provide one or more ports
that can be used from the outside of a CF environment.

Anyway I'll read the document you've pointed and collect more information
about the container networking.

Regards,

I'm not a member of the teams. But from what I recall, around the time
this issue was getting finished up and support in the CLI was being
considered, some usability problems in the API became apparent when
looking
at it from the CLI's perspective. At the same time the container
networking project started to pick up steam and I think given the overlap
between container networking regarding container listening ports coupled
with the API problems discovered as part of the CLI work the decision was
made to put the work on hold until container networking matured more and
revisit the feature and APIs then.

You might be able to piece together some info from the CLI proposal
document [0]. Hope that helps.

Thank you very much for the response, Zach,

I would love to hear about how and why you wish to use multiple ports
to
help inform how we replace this.
I've heard it multiple times from our users who wanted to migrate their
existing application(s) onto Cloud Foundry that they need to use
multiple
ports with an app for easier migration.

Now I know it's experimental. But it seems working completely well as
far
as
I have tested. So my next question is "why will you cease to support
this
(well-working) feature? Is there any issue / problem with it?"

Hey Noburou,

The multiple app ports were introduced as an experimental feature. I
believe we do not intend to continue supporting them in their current
incarnation, and to not currently have a concrete replacement.

I would love to hear about how and why you wish to use multiple ports
to
help inform how we replace this.

Thanks,
