Draft: [CI/CD] Build docker container and deploy to kube

[zinstack625]

This needs 3 secrets:

• DOCKERHUB_USERNAME
• DOCKERHUB_TOKEN
• KUBECONFIG

Before being ready for merge, container name needs changing. I don't know how it will be called, so this is blocked for now

container name needs changing

Maybe it's better to use a CI variable/secret as a container name?

[Fe-Ti]

Except for my concerns about using variables, everything looks nice

[Fe-Ti]

E.g. here could be something like

      image_name: ${{ secrets.DOCKERHUB_USERNAME }}/${{ vars.CONTAINER_NAME }}

[Fe-Ti]

Same goes for line 26:

kubectl rollout restart -n $NAMESPACE $RESOURCE_TYPE $RESOURCE

[Fe-Ti]

Maybe it's better to stop execution with error instead of hardcoding a link*:

die() {
    echo "$1"; exit 1
}
[ -z "$CONTAINER_NAME" ] && die 'CONTAINER_NAME is not set! Set envvar $CONTAINER_NAME'

• Fun note: I've tried to create account with dash, but docker hub said that it's prohibited :-)

[Fe-Ti]

I've made some changes to underlying library, so parameter notify_period was replaced with optional notify_schedule.

Also with recent changes¹ there is new command called notify, which triggers notification procedure. That in turn makes it possible to control notifications via cron.

---

¹ Now bot uses http and json if started with -s key. Input format is:

{
    "commands" : ["cmd",...] | "cmd"
}

[Fe-Ti]

This line (4) should be removed if we're going to rely on cron (I suppose it's better).

Or it should look like this (if we rely on internal implementation):

    "notify_schedule"       : ["09:00", "21:00"],
