Quickstart guide should be dead dead dead dead simple. The goal of the quickstart guide isn’t to tach people best practices around Magnum. It is to get a developer operational to give them that sense of feeling that Magnum can be worked on. The goal of any quickstart guide should be to encourage the thinking that a person involving themselves with the project the quickstart guide represents is a good use of the person’s limited time on the planet.

The specification of the memory size is optional, and the COE won’t reserve any memory to the containers with unspecified memory size. The debate is whether we should document this optional parameter in the quickstart guide. Below is the positions of both sides: Pros: · It is a good practice to always specifying the memory size, because containers with unspecified memory size won’t have QoS guarantee. · The in-development autoscaling feature [1] will query the memory size of each container to estimate the residual capacity and triggers scaling accordingly. Containers with unspecified memory size will be treated as taking 0 memory, which negatively affects the scaling decision. Cons: · The quickstart guide should be kept as simple as possible, so it is not a good idea to have the optional parameter in the guide. Thoughts?
