Automation Suite on EKS/AKS installation guide

Applying miscellaneous configurations

Note: Only apply the configurations in this section if you cannot provide admin privileges to the Automation Suite installer. If you can provide the required permissions to the installer, you do not need to apply the configurations in this section.

Creating a priority class

To create a priority class for UiPath® applications, take the following steps:

Save the following configuration as a YAML file:
```
---
apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: uipath-high-priority
value: 1000000
preemptionPolicy: PreemptLowerPriority
globalDefault: false
description: "Priority class for uipath applications"---
apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: uipath-high-priority
value: 1000000
preemptionPolicy: PreemptLowerPriority
globalDefault: false
description: "Priority class for uipath applications"
```
Run the following command, replacing the <file_name.yaml> placeholder with the actual name of your YAML file:
```
kubectl apply -f <file_name.yaml>kubectl apply -f <file_name.yaml>
```

Labeling the namespaces

To create namespace labels, run the following commands:

kubectl label namespace <uipath> uipath-injection=enabled
kubectl label namespace <uipath> istio-injection=enabledkubectl label namespace <uipath> uipath-injection=enabled
kubectl label namespace <uipath> istio-injection=enabled

Configuring CoreDNS

If you are using a proxy setup, specific CoreDNS configuration changes are required to ensure successful installation and operation of Automation Hub and Apps.

We recommend adding this to the CoreDNS settings as it allows any Service to Service requests, that use the FQDN of the cluster, to bypass the load balancer and route internally through Istio.

Follow these steps to configure your cluster during installation:

Capture the existing coredns configmap from the running cluster:
```
kubectl get configmap -n kube-system coredns -o yaml > coredns-config.yamlkubectl get configmap -n kube-system coredns -o yaml > coredns-config.yaml
```

Edit the coredns-config.yaml file to append the fqdn rewrite to the config.

Rename the configmap to coredns-custom.

Add the following code block to your coredns-config.yaml file. Make sure the code block comes before the kubernetes cluster.local in-addr.arpa ip6.arp line.

rewrite stop {
                        name exact <cluster-fqdn> istio-ingressgateway.istio-system.svc.cluster.local
                        }rewrite stop {
                        name exact <cluster-fqdn> istio-ingressgateway.istio-system.svc.cluster.local
                        }

Replace <cluster-fqdn> with the actual value.

Once you have completed these steps, your file should resemble the following sample:

apiVersion: v1
                data:
                Corefile: |
                .:53 {
                errors
                log
                health
                rewrite stop {
                name exact mycluster.autosuite.com istio-ingressgateway.istio-system.svc.cluster.local
                }
                kubernetes cluster.local in-addr.arpa ip6.arpa {
                pods insecure
                fallthrough in-addr.arpa ip6.arpa
                }
                prometheus :9153
                forward . /etc/resolv.conf
                cache 30
                loop
                reload
                loadbalance
                }
                kind: ConfigMap
                metadata:
                name: coredns-custom
                namespace: kube-systemapiVersion: v1
                data:
                Corefile: |
                .:53 {
                errors
                log
                health
                rewrite stop {
                name exact mycluster.autosuite.com istio-ingressgateway.istio-system.svc.cluster.local
                }
                kubernetes cluster.local in-addr.arpa ip6.arpa {
                pods insecure
                fallthrough in-addr.arpa ip6.arpa
                }
                prometheus :9153
                forward . /etc/resolv.conf
                cache 30
                loop
                reload
                loadbalance
                }
                kind: ConfigMap
                metadata:
                name: coredns-custom
                namespace: kube-system

Create the coredns-custom configmap:

kubectl apply -f coredns-config.yamlkubectl apply -f coredns-config.yaml

Replace the volume reference from coredns to coredns-custom in the coredns deployment in kube-system namespace:

volumes:
                - emptyDir: {}
                name: tmp
                - configMap:
                defaultMode: 420
                items:
                - key: Corefile
                path: Corefile
                name: coredns-custom
                name: config-volumevolumes:
                - emptyDir: {}
                name: tmp
                - configMap:
                defaultMode: 420
                items:
                - key: Corefile
                path: Corefile
                name: coredns-custom
                name: config-volume

Restart the coredns deployment and ensure the coredns pods are up and running without any issues:
```
kubectl rollout restart deployment -n kube-system corednskubectl rollout restart deployment -n kube-system coredns
```
