Managing Kubernetes

There may come a time, when you will need to exec or attach yourself to a Kubernetes container to see what is happening from within. It's all quite straightforward, albeit not intuitive, but here's where this tutorial might come in handy. So without further ado let's get into it.

Azure​

To access the Kubernetes, you should first see if you've got Azure CLI installed.

  • On Windows:
winget install -e --id Microsoft.AzureCLI
  • On Mac:
brew install azure-cli

If you run into any issues, please refer to Azure CLI Docs

You should now login using the following command and then selecting your computer user:

az login

Finally, in order to be granted the access to the Kubernetes, we also need to request for Elevated Privileges. When on page, you should click Activate next to ROLE_AAD_BIDS_COTR_PIM and in the sidebar menu fill in the Reason Request for elevated privileges

Kubernetes​

We are ready to authenticate, but we haven't yet prepared our Kubernetes environment, so let's first install

  • On Windows:
winget install -e --id Kubernetes.kubectl
winget install -e --id Microsoft.Azure.Kubelogin
  • On Mac:
brew install kubectl
brew install kubelogin

Connecting pieces together​

Now that we've got the prerequisites ready, we need Kubernetes to "inherit" some settings from Azure CLI:

# let's clear existing tokens (if there are any)
kubelogin remove-tokens
# let's select the correct subscription (although this may vary)
az account set --subscription "Gjensidige Production Modern"
# finally, let's get the credentials
az aks get-credentials --name aks-apps-int-prod-011 --resource-group gpm-plt-aks-apps-int-en-prod-rg

The result should look something like this: Successfully logged in

Do note that the cluster name or even a resource group can change. You can find the latest one at GAP website

Finally​

Using kubernetes themselves would be beyond this post, but I will leave Tor's suggestion of K9S here. It can help you do simple stuff with an in-terminal and very cool looking graphical interface: alt text

We can install that using:

  • On Windows
    scoop install k9s
  • On Mac
    brew install k9s
