Assign current AKS resource and name to linux variables

Question

I am running a script that requires the resource group and name of current AKS client config. Previously configured with az aks get-credentials ...

Current script: (I type AKS=something and RG=SOMETHING before running)

az aks update -g $RG -n $AKSNAME ...

Wanted script: (I type nothing before running)

AKSNAME=$(what goes here?)
RG=$(what goes here?)
az aks update -g $RG -n $AKSNAME ...

How can I load RG and AKSNAME values automatically through a shell script?

EDIT: I current assign the values to those variables by hand. I want the script to find the values automatically, corresponding to the cluster in the current context e.g. which kubectl is using.

If you just get the credential via the command az aks get-credentials .... without parameter --admin, then you can get the cluster name like this:

AKSNAME=$(kubectl config current-context)

And if you use the parameter --admin, then you need to change the command like this:

AKSNAME=$(kubectl config view --minify -o jsonpath='{.contexts[0].context.cluster}')

Then you can get the group name like this:

RG=$(az aks list --query "[?name == '$AKSNAME'].resourceGroup" -o tsv)
