[DISCUSS]Shall Java Chassis support random port
Hi:
Like spring-boot server.port=0, Java Chassis can support random port:
servicecomb:
rest:
address: 0.0.0.0:0
highway:
address: 0.0.0.0:0
Best Regards & Thanks!
回复： [DISCUSS]Shall Java Chassis support random port
Posted by bismy <bi...@qq.com>.
For security reasons, we should listen as less network interface as possible. So we make this design to listen only one network address. For users want this feature, it's really save a lot of time for them to configure ip address. I remember this is the original security reasons for 0.0.0.0 to listen only one address. However, we still follow the common ways, 0.0.0.0 to listen all possible network interface, and user have to configure the target network interface if they want only listen one network interface.
This problem regarding to random port, it is only hard to give port matrix to configure fire wall, and it's a option of users. I think we can provide this feature.

主题: Re: [DISCUSS]Shall Java Chassis support random port
for some production, they must provide communication matrix to final
customers before deploy software.
but in this time they DO NOT use port 0 feature just no problem.
so it's a false proposition
but to debate this problem with those peoples will waste a lot of time......

I think i got what wjm means "not safety", usually, we will add an
disclaimer at the feature in this situation, something like,
when setting port to 0, the port will be random assigned , the
security-related matters introduced by this are the responsibility of the
user.

The "not safety" explain doesn't make sense.
With the help of service-center, we can find out the port finally.

in fact, customer not set port to 0 means disable it, i don't think we need
a option.
"not safety" means, if customer set port to 0, they can not know which port
will be used
sigh, so strange......

Can we add an option for it?
In this way we can disable it when there is security issue we need to take
care.

I think is a good feature,
@wjm Could you provide more information about the safety issue? that is
a interesting topic.
