+
+To find which Go is required for a specific Kubernetes version,
+run the following commands in your Kubernetes working directory.
+Below example looks for all 1.29.z Kubernetes releases.
+
+```sh
+K8S_VERSION=1.29
+for tag in $(git tag | grep $K8S_VERSION);do git checkout -q tags/$tag;goVersion=$(cat ./build/dependencies.yaml | grep "golang: upstream version" -A 1 | grep version: | awk '{$1=$1;print}' );echo "Kubernetes $tag requires Go $goVersion";done
+```
+
+An example output will be
+```sh
+Kubernetes v1.29.0 requires Go version: 1.21.5
+Kubernetes v1.29.0-alpha.0 requires Go version: 1.20.6
+Kubernetes v1.29.0-alpha.1 requires Go version: 1.21.1
