Q: Daily stand-up list

Toby SpeightLike most teams, we take turns to speak in our daily stand-ups.

At present, we're all working remotely, so there's no physical ordering that we would agree on. And ...

> The image of a person holding a sword horizontally while striking a pose is the emoji that symbolizes a person fencing or a fencing match. It can refer to the sports itself not only to the individual or to a match. Fencer Emoji can mean "I would love to learn how to fence." or "Today we're going to see a fencing match."

The whole emoji thing has kind of gotten out of hand. What does a Mars emoji represent? Or an HST emoji?
 
Mars as in the planet?
because that'd be astrology
what do you mean by HST?
 
@Vogel612 Considering it's Donald, HST is probably Hubble.

Or he's really into high speed trains, heat shrink tubing...
 
Why is @Lurch slower than @Duga though
 
Could've been chance.
 
@skiwi Possibly a small time difference

@Vogel612 Duga's back! I'll shut down Lurch.
 
The code is using a cron schedule of once every minute, if Lurch is off by some milliseconds then....
Because there's no way @Duga would be off.
@Duga is always right.

No problem! I learned some things and it was kind of fun.

Duga is back? Where is Lurch?
 
Lurch is off duty.
:)
 
I see that the Bot-fight didn't last very long.
 
As soon I was made aware that Duga was back, I sent Lurch to the locker room.
 
He's a good second team.
 
Yes, and now that I have a very easy-to-spin up replacement, we're set for a while.
 
8:53 PM
;)
 
What would be nice, as Mast suggested, would be automatic failover, but it's probably not worth the effort. Yet.
Maybe if Duga gets refactored/rewritten, I can co-conspire on that part of things.
 
Main problem is you'd need a third body that keeps an eye on things.
The watchdog.
 
Kubernetes provides that out of the box.
 
That's nice for a centralized system, not for a decentralized one.
Considering Duga runs on different hardware than Lurch.
 
Kubernetes can orchestrate containers on multiple machines.
 
9:00 PM
If there's only 2 systems, Duga and Lurch, you can get away with 2 watchdogs, one on each.
Make one master, problem solved.
 
So for example, one could have a North American and a European "Duga" and tell k8s that you always want exactly one of them running. Simple as that.
 
Is Kubernetes decentralized as well, or would it have to run on the back-up system?
 
No, k8s is not decentralized by itself but can be combined with things like Rancher for that.
