Cards Against ________

A card game for people that think they know something about Kubernetes, Security, Containers, DevOps, or a combination of all that (let's be honest, they may be lying).

Don’t take this game seriously

House Rules

Jabba the Mutt

Every round, pick one random white card from the pile and place it into play. If Jabba the Mutt (the authors dog) wins the game, all players go home in a state of everlasting shame having being beaten by a dog that isn’t even playing.

Cards Against Containers “The Hard Way”

Hand out blank pieces of paper and pens to all players. Write your own content, then ensure that TLS is fully configured so no worker can send answers to etcd without full encryption. Full authentication is also required. Any cards produced without full role-based-access-control enabled will be marked in a failed state and cannot be recovered. External DNS is used to identify who is etcd at any point.

Never have I ever passed the CKA

At any time, players may discard cards that they don’t understand, but they must confess at their junior level of ignorance to the group and suffer the resulting humiliation. This may result in intensified imposter syndrome. If anyone acts smug at someone else’s ignorance, they must calculate the MD5 sum of the cards in their hand without technology aids or donate a point.

Scrum Ceremonies

Points can be gained outside of a game if players use any of the white cards during a Scrum ceremony (retrospective, standup, planning or review), bonus points if you get sent to HR for doing so.

Have you tried turning it off and on again?

At any time, a worker can trade in a point to return as many white cards as they’d like to the deck and take new cards to replace these to remain with 10 cards in hand.

Sidecar Cards

For 2 blanks, all players draw an extra card before playing the hand to open up more options and consume more resources.

Hard Mode

Play while running your own separate etcd cluster to support multiple production Kubernetes clusters, across multiple cloud providers, but refusing to use a managed Kubernetes service or any commercial solution. Bonus points for the added challenge of doing this whilst identifying as a minority.

Chaos Engineering

At any point during the game, etcd may mark a player as offline for an indeterminate amount of time before they start playing again. Etcd can choose to offline multiple players simultaneously, but the game must continue with no loss of comedy value or all players lose a point.


If a goose steals any cards during the game, players must give chase. If the goose chases any player during the game, they must hide in a phone box and phone an adult for assistance.

Continuous Delivery

Game play is continuous, etcd draws a blue card at a rate of one every 10 seconds. Workers must place their white card(s) within this pipeline window or be excluded from that draw.

Asynchronous Games

Play the game entirely in something like with no live communication with other players. Use something like Slack to collaborate and record when everyone has completed their go. This game may take weeks.

Imposter Syndrome

Question every card you are about to play, wondering if others in the room are laughing at your misunderstanding of a technical concept or whether they’ll think your sense of humour is strange. After playing your card, realise that you’re all on the same page, then feel silly for thinking that, then feel like everyone knows your feeling silly. You all think I’m silly for writing this don’t you? You hate this game. I’m sorry, maybe we shouldn’t publish it?

Whatever you think you’re feeling, we felt it in writing this game 100x over. You are awesome.
