Login to Kubernetes clusters

Users can now login to cloud clusters with the help of Odin via using one single command.

Prerequisites

To enable the login using Odin, user needs to maintain the following;

1. Odin version 1.4.1 and above is required for this to work. Please use brew install dream11/tools/odin to upgrade to Odin's latest version.

2. User needs to install Kubernetes plugin to login to Kubernetes clusters. The steps to install the same can be found here - Github Documentation for installing kubernetes plugin.

Steps to login to kubernetes clusters

Step 1: Obtain Cluster Name:

Users need to know the cluster name that they are looking to login to.

• For each environment created by the users, there is an associated cluster which can be obtained by running the commands below.

// Describe environment to get the attached cluster name

odin describe env --name Your-Env-Name

• Once the above command is executed, users can find the cluster name under "cluster" variable in the output.

Sample field details for the Cluster Name

Pro tip: Run this command to get cluster name directly

odin describe env --name rush-d11 | grep cluster | awk '{print $2}'

Step 2: Use cluster name from above step to login to cluster

Once the cluster name is obtained, user can login by using the following command. Please note, to obtain the cluster name and execute this command, users must follow the Prerequisites.

// Command to login to the cluster

kubectl login Your-Cluster-Name

Pro tip: Add this in your .bashrc/.zshrc to alias and automate the complete process and

source .bashrc/.zshrc

---

Run this for .bashrc

if ! grep -q 'k8slogin() {' ~/.bashrc; then
    echo 'k8slogin() {
    cluster=$(odin describe env "--name" "$1" | grep cluster | awk '\''{print $2}'\'')
    kubectl login $cluster
}' >> ~/.bashrc
fi

Run this for .zshrc

if ! grep -q 'k8slogin() {' ~/.zshrc; then
    echo 'k8slogin() {
    cluster=$(odin describe env "--name" "$1" | grep cluster | awk '\''{print $2}'\'')
    kubectl login $cluster
}' >> ~/.zshrc
fi

Post this you can simply run

k8slogin Your-Env-Name
