As I kept running into GitHub auth issues on each new local setups, I documented the steps here.

This gist documents how to set up your local dev env, especially on a headless Ubuntu machine, to push local Git changes to remote GitHub repositories.

It features

fine-grained auth token
headless env, e.g. remote ubuntu dev machine, where browser-based auth does not work well

Generate a personal access token in GitHub UI

To acquire the permission to push local changes to the remoate GitHub repos.

A new Deployment will take effect when it's applied.

kubectl apply -f deployment.yaml
kubectl get deployment myapp-deployment # to verify the deployment

The kubectl apply command and the kubectl rollout command serve different purposes in managing deployments in Kubernetes.

kubectl apply

Primary Use: The kubectl apply command is used to create or update resources in a Kubernetes cluster. It takes a configuration file (usually in YAML format) and applies it to the cluster. This is the command you use to initially create objects like Deployments, Services, ConfigMaps, etc., or to apply changes to them.

	# reboot

	# how this works
	# When you connect an input device, such as a keyboard or mouse, to your system, udev triggers various rules.
	# If the connected device is recognized as part of the input subsystem and has a power/control attribute, this
	# rule will set that attribute to "on", effectively disabling USB autosuspend for that device.
