Percona Everest quick install guide

Helm simplifies the installation of Percona Everest. With this guide, you’ll be up and running with Percona Everest in no time. However, we also have a comprehensive installation guide that covers all possibilities.

Percona Helm charts can be found in percona/percona-helm-charts repository in Github.

Alternative installation method

If you prefer an alternative method, you can install Percona Everest using everestctl.

Prerequisites

Before getting started with Percona Everest, do the following:

  1. Install Helm v3 .

  2. Install yq .

  3. Set up a Kubernetes cluster.

    Note

    Percona Everest assists with installing all the necessary operators and required packages, but does not deploy a Kubernetes cluster.

    We recommend setting up Percona Everest on the Amazon Elastic Kubernetes Service (EKS) or Google Kubernetes Engine (GKE).

    Create EKS cluster Create GKE cluster

  4. Verify that you have access to the Kubernetes cluster that you want to use with Everest. By default, Everest uses the kubeconfig file available under ~/.kube/config.

    If your file is located elsewhere, use the export command below to set the KUBECONFIG environment variable:

    export KUBECONFIG=~/.kube/config

    To verify access to the Kubernetes cluster, run the following command:

    kubectl get nodes
    Expected output 
    NAME                                    STATUS   ROLES    AGE   VERSION
gke-<name>-default-pool-75d48bfc-bx8g   Ready    <none>   11h   v1.26.7-gke.500
gke-<name>-default-pool-75d48bfc-c2df   Ready    <none>   11h   v1.26.7-gke.500
gke-<name>-default-pool-75d48bfc-zl7k   Ready    <none>   11h   v1.26.7-gke.500

Install Percona Everest

To install Percona Everest using Helm follow these steps:

  1. Add the Percona Helm repository.

    helm repo add percona https://percona.github.io/percona-helm-charts/
helm repo update

  2. Install Percona Everest.

    helm install everest-core percona/everest \
--namespace everest-system \
--create-namespace
    🌐 Install Percona Everest and access it using Ingress

    Prerequisite

    • An Ingress controller (e.g., Nginx) installed on your Kubernetes cluster

    • If TLS is required on your Ingress endpoint, a Secret containing the TLS certificates

    Example

    To install Percona Everest and access using Ingress, here are the steps:

    1. Install Percona Everest:

      helm install everest percona/everest \
  -n everest-system \
  --set ingress.enabled=true \
  --set ingress.ingressClassName="" \
  --set ingress.hosts[0].host=everest.example.com \
  --set ingress.hosts[0].paths[0].path=/ \
  --set  ingress.hosts[0].paths[0].pathType=ImplementationSpecific
      Replace everest.example.com with your own domain.

    2. Verify Ingress:

      kubectl get ingress -n everest-system

      Make sure the address provided is valid and that it correctly routes to the Percona Everest service.

    Example: Custom YAML configuration file 

    ingress:
# -- Enable ingress for Everest server
enabled: true
# -- Ingress class name. This is used to specify which ingress controller should handle this ingress.
ingressClassName: "nginx"
# -- Additional annotations for the ingress resource.
annotations: {}
# -- List of hosts and their paths for the ingress resource.
hosts:
    - host: everest.example.com
      paths:
        - path: /
          pathType: ImplementationSpecific
# -- TLS configuration for the ingress resource.
# -- Each entry in the list specifies a TLS certificate and the hosts it applies to.
tls: []
#  - secretName: everest-tls
#    hosts:
#      - everest.example.com
    Install Percona Everest using this file:

    helm install everest percona/everest \
-n everest-system \
-f everest-values.yaml
    🔒 Install Percona Everest with TLS enabled

    Install Percona Everest with TLS enabled:

    helm install everest-core percona/everest \
--namespace everest-system \
--create-namespace
--set server.tls.enabled=true

    For comprehensive instructions on enabling TLS for Percona Everest, see the section TLS setup with Percona Everest.

    Once Percona Everest is running successfully, you can create additional database namespaces. For detailed information, refer to the section on namespace management.

    Note

    • If dbNamespace.namespaceOverride is set, the specified namespace will be provisioned instead of the default everest namespace.
    • If dbNamespace.enabled=false is set, no namespaces will be provisioned. You can provision namespaces later with the everestctl namespaces add <NAMESPACE> command.
    • If you installed Percona Everest using helm and need to uninstall it, make sure to uninstall it exclusively through helm for seamless removal.

Post-installation steps

Once you have successfully installed Percona Everest, proceed with the following steps:

  1. Retrieve the admin password.

    kubectl get secret everest-accounts -n everest-system -o jsonpath='{.data.users\.yaml}' | base64 --decode  | yq '.admin.passwordHash'

    Note

    The default admin password is stored in plain text. It is highly recommended to update the password using everestctl to ensure that the passwords are hashed.

    For information on user management, see the section manage users in Percona Everest.

  2. Access the Everest UI/API using one of the following options, as the everest Service is not exposed with an external IP by default:

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

      helm install percona-everest percona/everest \
--set service.type=LoadBalancer
      When TLS is enabled 
      NAME      TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)          AGE
everest   LoadBalancer   10.43.172.194   34.175.201.246       443:8080/TCP    10s

    2. 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

    To access Percona Everest, open your browser and go to: https://everest.example.com.

    Note

    Replace everest.example.com with your own domain.

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

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

    2. 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
      When TLS is enabled 
      kubectl get svc/everest -n everest-system
NAME      TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
everest   NodePort   10.43.139.191   <none>        443:32349/TCP   28m

    3. Retrieve the external IP addresses for the kubernetes cluster nodes.

      Expected output 
      NAME                                          STATUS   ROLES    AGE   VERSION               INTERNAL-IP     EXTERNAL-IP      OS-IMAGE                             KERNEL-VERSION CONTAINER-RUNTIME
gke-everest-test-default-pool-8bbed860-65gx   Ready    <none>   3m35s v1.30.3-gke.1969001   10.204.15.199   34.175.155.135   Container-Optimized OS from Google   6.1.100+       containerd://1.7.19
gke-everest-test-default-pool-8bbed860-pqzb   Ready    <none>   3m35s v1.30.3-gke.1969001   10.204.15.200   34.175.120.50    Container-Optimized OS from Google   6.1.100+       containerd://1.7.19
gke-everest-test-default-pool-8bbed860-s0hg   Ready    <none>   3m35s v1.30.3-gke.1969001   10.204.15.201   34.175.201.246   Container-Optimized OS from Google   6.1.100+       containerd://1.7.19

    4. 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.

    The kubectl port-forward command in Kubernetes is used to create a temporary connection between your local machine and a specific Kubernetes resource (e.g., a Pod, Service, or Deployment) by forwarding traffic from a local port to a port on the resource.

    1. Run the following command to setup a port-forward to the Percona Everest server service:

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

      Percona Everest will be available at http://127.0.0.1:8080. This method is mostly useful for testing purposes.

      When TLS is enabled 
      kubectl port-forward svc/everest 8443:443 -n everest-system

      Percona Everest will be available at https://127.0.0.1:8443.
