Portainer on Kubernetes with Helm

Portainer can be installed via Helm, which is a package manager for Kubernetes. Helm simplifies the deployment and management of applications on Kubernetes clusters.

To install Portainer via Helm, you would typically follow these steps:

Add the Portainer Helm repository:

helm repo add portainer https://portainer.github.io/k8s/
helm repo update

Install Portainer with Helm:

To install Portainer and set it to use port 80, you can override the default service type (ClusterIP) to NodePort or LoadBalancer, and set the service port to 80. Here's an example of how to install Portainer using Helm with the service exposed on port 80:

helm install portainer portainer/portainer
--namespace portainer
--create-namespace
--set service.type=NodePort
--set service.nodePort=80

Note: The --create-namespace flag tells Helm to create the namespace if it doesn't already exist.

Important Security Note: Exposing Portainer on port 80 without TLS can be insecure, especially if you are not on a private network. It is generally recommended to use HTTPS for web interfaces. If you are on a cloud provider, using a LoadBalancer with SSL termination or an Ingress with TLS would be more secure.

If you are using a LoadBalancer and want to expose Portainer on port 80, the service type should be set to LoadBalancer and further configuration will be necessary to ensure your LoadBalancer routes external traffic on port 80 to the appropriate service port.

Access Portainer:

After installation, if you have used NodePort, you can access Portainer by finding out which IP and port to connect to:

kubectl get svc -n portainer

Look for the portainer service, and you will find the port mapped to port 80 on your node under the PORT(S) column.

If you used LoadBalancer and you're on a cloud platform, the external IP address will be assigned by the cloud provider. You can find it with the same command:

kubectl get svc -n portainer

Then, access Portainer using the external IP provided by the cloud provider.

Please note that using Helm charts, you can also deploy Portainer with advanced configurations, such as specifying your own values in a custom values.yaml file or setting values via the --set flag as shown above.

Remember, exposing services on well-known ports like 80 and 443 can make them targets for malicious activity. Always ensure that you have proper security measures in place, such as firewalls, access controls, and monitoring, to protect your services.
