Helm -- How to connect helm to different k8 clusters

Check Helm Configuration (Optional)

You can check the Helm configuration and ensure it’s working correctly with the current Kubernetes context:

helm env


-------------------------------------------------


 helm install my-release bitnami/mongodb --kubeconfig /path/to/kubeconfig-dev

~/.kube/config 

we can also set a our chosen 


To ensure that Helm is deploying in the correct Kubernetes context, you need to verify which context Helm is using. Helm uses the kubectl context specified in the kubeconfig file to determine which Kubernetes cluster to deploy to. Here's how you can check and confirm the context:

1. Check the Current Kubernetes Context

Helm relies on the current context set in kubectl. To verify the current context, use the following command:

kubectl config current-context

This command will return the name of the context that kubectl (and thus Helm) is currently using.

2. Verify the Context Details

To see the details of the current context, including the associated cluster and user, use:

kubectl config view --minify

This command provides information about the current context, cluster, and user. It’s useful for double-checking that you’re working with the correct configuration.

3. Ensure Helm Uses the Same Context

Helm does not have its own context management; it uses the context specified by kubectl. If you switch contexts in kubectl, Helm will automatically use that context for deployments.

Steps to Ensure Correct Context in Helm:

  1. Set the Correct Context in kubectl:

kubectl config use-context <context-name>

Replace <context-name> with the name of the context you want to use (e.g., prod-context, dev-context).

Deploy Using Helm: Once you’ve set the correct context in kubectl, any Helm command will use that context. For example:

helm install my-release bitnami/mysql

Check Helm Releases: To verify that Helm is operating in the correct context, you can list Helm releases and see which Kubernetes context they are associated with:

helm list

Kube-Proxy : Configure Production Grade Cluster

Configuring kube-proxy involves setting up its behavior for managing network traffic within a Kubernetes cluster. Here's a general guide: 1. Understand kube-proxy Modes kube-proxy supports two main modes for handling traffic: iptables Mode: Uses Linux iptables for routing traffic. It's simple and widely supported. IPVS Mode: Uses Linux Virtual Server (IPVS) for advanced load balancing and connection tracking. Configuring iptables mode for kube-proxy involves setting up network rules to route traffic efficiently within a Kubernetes cluster. Here's a step-by-step guide: Step 1: Verify kube-proxy Mode By default, kube-proxy operates in iptables mode . To confirm this: kubectl get configmap kube-proxy -n kube-system -o yaml Look for the mode field in the configuration file. Step 2: Modify kube-proxy Configuration If kube-proxy is not in iptables mode, update its configuration: Edit the kube-proxy ConfigMap: kubectl edit configmap kube-proxy -n kube-system Set the proxy-mod...

Networking : How is the Kubernetes networking done CNI is after cluster is running

 In Kubernetes, networking can be set up at different stages, depending on your requirements and the tools you're using. Here's a breakdown: 1. During Provisioning (e.g., via Terraform): VPC/Network Setup: When you're provisioning your infrastructure (e.g., on AWS, Azure, GCP) using Terraform, you'll typically set up the underlying network components first. This includes creating Virtual Private Clouds (VPCs), subnets, security groups, routing tables, etc. These components define the network within which your Kubernetes cluster will operate. Cluster Networking Configuration: When you provision a Kubernetes cluster using Terraform, you might also configure networking settings such as: Pod CIDR: The range of IP addresses for Pods. Service CIDR: The range of IP addresses for services. Network Policies: To control the communication between pods. 2. After Provisioning: CNI Plugin Installation: Once the cluster is up and running, you need to set up the container network...

Laptop : Configure your laptop to connect to AKS - Azure

To configure your laptop to connect to an Azure Kubernetes Service (AKS) cluster, follow these steps: Install Prerequisites Azure CLI: Install the Azure CLI to interact with Azure resources. For installation instructions, visit Azure CLI Installation Guide . kubectl: Install the Kubernetes CLI tool to manage your AKS cluster. Install it using Azure CLI: az aks install-cli Authenticate with Azure Log in to your Azure account using the Azure CLI: az login If you have multiple subscriptions, set the desired subscription: az account set --subscription "<subscription-id>" Connect to the AKS Cluster Retrieve the cluster credentials and configure kubectl : az aks get-credentials --resource-group <resource-group-name> --name <aks-cluster-name> This command downloads the kubeconfig file and sets up kubectl to interact with the cluster. Verify the Connection Check the nodes in your AKS cluster: kubectl get nodes Optional: Use Azure Cloud Shell If you prefer not to ...
