# Grouping Instances
|
|
|
|
Sometimes Instances become quite large with many components. If you work on them with multiple team members, you end up having to synchronize the deployment of the Instances.
|
|
|
|
You can easily rip large Instances apart using the `group` tag, joining multiple Instances into one group and making sure the NetworkPolicies are opened to pods from other Instances within the Instance Group.
|
|
|
|
```yaml
|
|
global:
|
|
instance:
|
|
# -- despite the instance name, all components within this group will be prefixed
|
|
# with the group (unless the group name and the environment name are not identical)
|
|
# Also this makes sure the network policies are acting on the group, not on the instance.
|
|
group: "sample-group"
|
|
```
|
|
|
|
You can query the instance group in your code with `.instance.group`.
|
|
|
|
Example: We build multiple Instances in one group:
|
|
|
|
- sample-group-backend
|
|
- Database
|
|
- nstl
|
|
- rs
|
|
- sample-group-middleware
|
|
- nappl
|
|
- application(s)
|
|
- sample-group-frontend
|
|
- web
|
|
- cmis
|
|
|
|
Portainer is showing the group as if it were an single instance:

|
|
|
|
The nplus UI is showing the instances of the group:
|
|
|
|
|
|
|
|
And the nplus CLI is also showing single instances:
|
|
|
|
```

% kubectl get nscale
