[openstack-dev] [Zun]Use 'uuid' instead of 'id' as object ident in data model

[Wenzhi Yu]

Hi team,

I need your advice on this patch[1], which aims to implement etcd DB data model 
and API
for 'ResourceClass' object.

As you may know, in mysql implementation, mysql will generate a 'id' field, 
which is an
unique and auto increase integer. The 'id' is also used as 'primary key' or 
'foreign key'
in mysql[2].

However, in etcd implementation, etcd will NOT generate this 'id' itself, so I 
intend to
use the 'uuid' attribute of the object instead of 'id', and modify the DB API 
method to use
'uuid' as object ident instead of 'id', like[3]. Personally I feel using 'uuid' 
is more
reasonable because 'id' is a specific field in DB like mysql, seems it does not 
have actual
meaning in data model, right?

An alternative way Hongbin suggested is to generate an unique 'id' like mysql 
by ourselves
and insert the 'id' into etcd data model. But he said he's OK with the idea to 
replace 'id'
with 'uuid' if it does not break anything.

What's your opinion on this issue? Thanks in advance!

Hi team,
 
I am going to propose an exchange of the core team membership as below:
 
+ Shubham Kumar Sharma (shubham)
- Chandan Kumar (chandankumar)
 
Shubham contributed a lot for the container image feature and active on reviews 
and IRC. I think he is a good addition to the core team. Chandan became 
inactive for a long period of time so he didn’t meet the expectation of a core 
reviewer anymore. However, thanks for his interest to join the core team when 
the team was found. He is welcomed to re-join the core team if he become active 
in the future.
 
According to the OpenStack Governance process [1], we require a minimum of 4 +1 
votes from Zun core reviewers within a 1 week voting window (consider this 
proposal as a +1 vote from me). A vote of -1 is a veto. If we cannot get enough 
votes or there is a veto vote prior to the end of the voting window, this 
proposal is rejected and Shubham is not able to join the core team and needs to 
wait 30 days to reapply.

[openstack-dev] [devstack][CI] Etcd server setuped in devstack script can not be reached in CI unit tests

[Wenzhi Yu (yuywz)]

Hi all,

I intended to use etcd as data store for Zun project. So I installed docker and 
started a docker container with an etcd server running in it using
devstack script.  The etcd server listens on 127.0.0.1:2379 for client 
requests. And per CI log [1] the container had been started successfully and
functioned well (I added some test code and etcd server is available on 
127.0.0.1:2379).

But during the execution of unit test cases, the connection to 127.0.0.1:2379 
became inavailable [2], all the cases tried to connect to etcd server
failed. I did some investigation and found that the test cases were running in 
an isolated network environment (maybe within an container?).
So the etcd server can not be reached via 127.0.0.1:2379 during test run.

I intended to configure etcd server to listen on an IP address which can be 
reached from the test envrionment, but I realized that even if I did that,
it's not easy to query that IP address in test cases. An alternative method is 
to forward the request sent to 127.0.0.1:2379 of test environment to
corresponding socket of the environment inwhich the etcd container is running.

Now I have no idea how to deal with this issue, please help me out! Thanks in 
advance!

Both Sudipta and Wenzhi have been actively contributing to the Zun project for
