I created an instance template. And used it to create an autoscaled instance group.
I wanted to know, what is the best way to make changes to this instance template so changes are pushed to all instances created from this image automatically.
Edit: To further explain my usecase. My application requires full access to shell so creating an instance template seems like the only way for me. The docs say I cannot update my instance template. Is there a workaround for this? What is the standard way of tackling this.
