Microk8s: Remove basic-auth-file it is deprecated

[ktsakalozos]

We should remove the basic-auth-file argument and move any entries to the tokens file.

@ktsakalozos I believe this is good issue to start with for beginner like me. Do you mind if I take this issue ?

Thank you for volunteering @vbmade2000. Yes, it is a good first issue to get you familiar with the code. Here are some notes you might find helpful.

• In https://github.com/ubuntu/microk8s/tree/master/microk8s-resources/default-args we keep the default arguments that are copied under /var/snap/microk8s/current/args upon installation. You should remove the basic-auth-file entry (https://github.com/ubuntu/microk8s/blob/master/microk8s-resources/default-args/kube-apiserver#L4) from there.
• The password created in the install script (https://github.com/ubuntu/microk8s/blob/master/snap/hooks/install#L24) should be added as a token to the known_tokens file as we do for example for the controller (https://github.com/ubuntu/microk8s/blob/master/snap/hooks/install#L47).

Do not hesitate to reach out in case you need help.

Many thanks.

Sounds good. Thanks.

Will check and reach out to you in case of query.

@ktsakalozos Can you please point me to the architectural docs for microk8s ? I checked https://microk8s.io/docs/ but looks like it shows usage mostly. I want to understand how it sets up a single node k8s cluster.

[ktsakalozos]

@vbmade2000 there is no architectural doc. To understand how we setup a cluster, fist look at the basics of snaps [1] (MicroK8s is a snap package). Then read through the daemons and commands defined in spancraft.yaml [2]. The commands and daemons are wrappers [3] around the (k8s) binaries we package.

The single node cluster is straight forward as the daemons start with the default arguments [4] and the certificates generated during installation [5, 6]. The case of forming a cluster is a bit more involving so a few python scripts are used [7].

You are however on point, we need to put more time and effort on the dev docs.
