Step 9: Install hybrid runtime

Apply the configuration to the cluster

Use the following steps to install Apigee hybrid into your cluster:

Be sure that you are in the hybrid-base-directory/hybrid-files directory.
Verify that kubectl is set to the correct context using the following command. The current context should be set to the cluster to which you are deploying Apigee hybrid.
```
kubectl config get-contexts | grep \*
```
For Anthos on bare metal, AWS on GKE, EKS, and GKE on prem platforms only, Verify that the KUBECONFIG variable is set using the following command.
```
echo $KUBECONFIG
```
Do a dry run initialization. Execute the init command with the --dry-run flag. Doing a dry run lets you check for any errors before any changes are made to the cluster.
In hybrid version 1.5.10, the syntax of the --dry-run flag depends on the version of kubectl you are running. Check the version of kubectl with the following command:
```
kubectl version
```
kubectl version 1.17 and older:
```
$APIGEECTL_HOME/apigeectl init -f overrides/overrides.yaml --dry-run=true
```
kubectl version 1.18 and newer:
```
$APIGEECTL_HOME/apigeectl init -f overrides/overrides.yaml --dry-run=client
```
If there are no errors, execute the init command as follows:
```
$APIGEECTL_HOME/apigeectl init -f overrides/overrides.yaml
```
The init command installs the Apigee deployment services Apigee Deployment Controller and Apigee Admission Webhook.

To check the status of the deployment, you can use the following commands:

$APIGEECTL_HOME/apigeectl check-ready -f overrides/overrides.yaml

kubectl get pods -n apigee-system

kubectl get pods -n istio-system

When the pods are ready, go to the next step.

Do a dry run install. Execute the apply command with the --dry-run flag.

kubectl version 1.17 and older:

$APIGEECTL_HOME/apigeectl apply -f overrides/overrides.yaml --dry-run=true

kubectl version 1.18 and newer:

$APIGEECTL_HOME/apigeectl apply -f overrides/overrides.yaml --dry-run=client

If there are no errors, you can apply the Apigee-specific runtime components to the cluster with the following command:
```
$APIGEECTL_HOME/apigeectl apply -f overrides/overrides.yaml
```
To check the status of the deployment, run the following command:
```
$APIGEECTL_HOME/apigeectl check-ready -f overrides/overrides.yaml
```
Repeat this step until the pods are all ready. The pods may take several minutes to start up.
