Step 8: 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.
```
cd $HYBRID_FILES
```
Note: Because the overrides file specifies service account files using paths relative to your hybrid-base-directory/hybrid-files directory, you must execute the commands from within that 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. Doing a dry run lets you check for any errors before any changes are made to the cluster. Execute the init command with the --dry-run flag as follows:
```
${APIGEECTL_HOME}/apigeectl init -f overrides/overrides.yaml --dry-run=client
```
Note: Apigee hybrid 1.8 supports kubectl version 1.21 and newer. If you are installing an older version of hybrid and using kubectl version 1.8 or older the syntax for the --dry-run flag will be --dry-run=true. You will need to update your kubectl to version 1.21 or newer before installing Apigee hybrid 1.8.
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 apigee

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

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

${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.
