Install Everest¶

Before you start¶

Before running the commands in the Installation section, note that Everest will search for the kubeconfig file in the ~/.kube/config path. If your file is located elsewhere, use the export command below to set the KUBECONFIG environment variable:

export KUBECONFIG=~/.kube/config

Installation¶

To install and provision Percona Everest to Kubernetes:

Download the latest release of everestctl to provision Percona Everest. For detailed installation instructions, see CLI installation documentation.
Install Percona Everest using one of the following commands:
```
everestctl install
```
Enter the specific names for the namespaces you want Percona Everest to manage, separating each name with a comma. These namespaces are restricted and cannot be used for deploying databases. Make sure that you enter at least one namespace.

Alternatively, you can set multiple namepaces in the headless mode:
```
everestctl install --namespaces <namespace-name1>,<namespace-name2> --operator.mongodb=true --operator.postgresql=true --operator.xtradb-cluster=true --skip-wizard
```
Replace <namespace-name> with the desired name for your namespace.
Example
```
everestctl install --namespaces dev,prod --operator.mongodb=true --operator.postgresql=true --operator.xtradb-cluster=true --skip-wizard
```
To gain a deeper understanding of how to install different operators in various namespaces, refer to the configure multiple namespaces section.
Update the password for the admin user:
```
everestctl accounts set-password --username admin
```
Important
- You can retrieve the automatically generated password by running the everestctl accounts initial-admin-password command. However, this password isn’t stored securely.
To access detailed information about user management, see the Manage users in Percona Everest section.

Access the Everest UI/API using one of the following options for exposing it, as Everest is not exposed with an external IP by default:

Load BalancerNode PortPort Forwarding

Use the following command to change the Everest service type to LoadBalancer:

kubectl patch svc/everest -n everest-system -p '{"spec": {"type": "LoadBalancer"}}'

Retrieve the external IP address for the Everest service. This is the address where you can then launch Everest at the end of the installation procedure. In this example, the external IP address used is http://34.175.201.246:
```
kubectl get svc/everest -n everest-system
```
Expected output
```
NAME      TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)          AGE
everest   LoadBalancer   10.43.172.194   34.175.201.246       8080:8080/TCP    10s
```

A NodePort is a service that makes a specific port accessible on all nodes within the cluster. It enables external traffic to reach services running within the Kubernetes cluster by assigning a static port to each node’s IP address.

Run the following command to change the Everest service type to NodePort:

kubectl patch svc/everest -n everest-system -p '{"spec": {"type": "NodePort"}}

The following command displays the port assigned by Kubernetes to the everest service, which is 32349 in this case.

kubectl get svc/everest -n everest-system
NAME      TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
everest   NodePort   10.43.139.191   <none>        8080:32349/TCP   28m

Retrieve the external IP addresses for the kubernetes cluster nodes.

kubectl get nodes -o wide
NAME                   STATUS   ROLES    AGE   VERSION

To launch the Percona Everest UI and create your first database cluster, go to the IP address/port found in steps 2 and 3. In this example, the external IP address used is http://34.175.155.135:32349. Nevertheless, you have the option to use any node IP specified in the above steps.

Run the following command to use Kubectl port-forwarding for connecting to Everest without exposing the service:

kubectl port-forward svc/everest 8080:8080 -n everest-system

To launch the Percona Everest UI and create your first database cluster, go to your localhost IP address http://127.0.0.1:8080.
