Let's simplify it:
can I write 5 different pod yamls, put in it a kind of "tag" and write an API 
request (request should have "tag" value) that will run ONE random pod from 
those 5?

So:
I have 3 types of devices. Each device has assigned container - to access 
device you have to connect to container and from there you can use device.
Containers have special environment variable describing to which device it is 
assigned, e.g. B4 - which means: device type B, number 4.

Now we are lending access to device by manually passing access to chosen 
container, but my need is to automate it: developer sends request: I need 
device type A. System checks if there is any resource available and gives 
access to developer. When developer is done, he sends request: ok, I'm done. 
Ramp down the container. And next user can request for it.

Hi Rodrigo,
I cannot find an example for one thing:
Let's say I have 3 pods defined:
type: A, unique_variable: 111
type: A, unique_variable: 222
type: A, unique_variable: 333

Now: how can I use API or Kubectl to create random pod of type A?


Kind regards,
Tomasz

[kubernetes-users] Looking for service pool managing solution

2018-05-17 Thread tomasz . szandala
Greetings,
I am looking for a software to manage a pool of application, using API and 
database system. Let me show You my problem:
I have 3 types of services: A, B and C. Each one requires outside resource, so 
we distinguish each instance. e.g.: I have 6 A-type virtual machines { A1, 
A2,.., A6}, 3 B-type: {B1,B2,B3} and 10 C-type. Each instance has its own 
internal setup, mostly IPs to remote resources. Now I want my managing system 
to solve usecases:
1. One of Jenkinses (I could have few) needs to test something using A-type 
instance. He sends API request and gets details to about random from that type 
and uses it. When he is done, the instance isfreed and returned using API.
2. A software developers needs some manual tests and asks for C-type instance. 
He sends an API request and gets details on one of those instances.
3. Only one "user" (Jenkins or human) can be using given instance at any time.
4. I need to be able to check who/what is using any of the instances at any 
time (can also be API query).
5. There needs to be security logs - when who requested what, what he got in 
return.


I am looking for a system to solve this problem, one of my Colleagues hinted me 
to use Kubernetes - since the "instance" can be containers with uniqe 
configuration it might be possible, but could anyone comment: does Kubernetes 
satisfies all my needs? Or maybe something else?
