A presentation at JUG Summer Camp in in La Rochelle, France by Horacio Gonzalez
Kubernetes: beyond Minikube Speaker: Horacio Gonzalez @LostInBrittany #JSC2019 #BeyondMinikube @LostInBrittany
Horacio Gonzalez @LostInBrittany Spaniard lost in Brittany, developer, dreamer and all-around geek #JSC2019 #BeyondMinikube @LostInBrittany
Summary What I would like to speak about: ○ Orchestrating containers ○ Kubernetes: some concepts ○ I have deployed on Minikube, woah! ○ From Minikube to prod ○ Building a managed Kubernetes service #JSC2019 #BeyondMinikube @LostInBrittany
Orchestrating containers Like herding cats… but in hard mode! #JSC2019 #BeyondMinikube @LostInBrittany
From bare metal to containers Another paradigm shift #JSC2019 #BeyondMinikube @LostInBrittany
Containers are easy… For developers #JSC2019 #BeyondMinikube @LostInBrittany
Less simple if you must operate them Like in a production context #JSC2019 #BeyondMinikube @LostInBrittany
And what about microservices? Are you sure you want to operate them by hand? #JSC2019 #BeyondMinikube @LostInBrittany
Taming microservices with Kubernetes #JSC2019 #BeyondMinikube @LostInBrittany
Kubernetes Way more than a buzzword! #JSC2019 #BeyondMinikube @LostInBrittany
Masters and nodes #JSC2019 #BeyondMinikube @LostInBrittany
Some more details #JSC2019 #BeyondMinikube @LostInBrittany
Desired State Management #JSC2019 #BeyondMinikube @LostInBrittany
Having identical, software defined environments #JSC2019 #BeyondMinikube @LostInBrittany
Extending Kubernetes #JSC2019 #BeyondMinikube @LostInBrittany
Extension example: Istio, a service mesh for Kubernetes #JSC2019 #BeyondMinikube @LostInBrittany
Minikube: K8s on my laptop A great fastlane into Kubernetes #JSC2019 #BeyondMinikube @LostInBrittany
Running a full K8s in your laptop A great learning tool #JSC2019 #BeyondMinikube @LostInBrittany
Your laptop isn’t a true cluster Don’t expect real performances #JSC2019 #BeyondMinikube @LostInBrittany
Minikube is only the beginning #JSC2019 #BeyondMinikube @LostInBrittany
From Minikube to prod A journey not for the faint of heart #JSC2019 #BeyondMinikube @LostInBrittany
The truth is somewhere inside… #JSC2019 #BeyondMinikube @LostInBrittany
The network is going to feel it… #JSC2019 #BeyondMinikube @LostInBrittany
The security journey #JSC2019 #BeyondMinikube @LostInBrittany
The storage dilemma #JSC2019 #BeyondMinikube @LostInBrittany
The ETCD vulnerability #JSC2019 #BeyondMinikube @LostInBrittany
Managed Kubernetes Don’t try it at home, folks! #JSC2019 #BeyondMinikube @LostInBrittany
Kubinception: running K8s on K8s Using Kubernetes to run Kubernetes #JSC2019 #BeyondMinikube @LostInBrittany
Kubinception: where are the nodes? #JSC2019 #BeyondMinikube @LostInBrittany
Kubinception with several customers #JSC2019 #BeyondMinikube @LostInBrittany
And the ETCD? #JSC2019 #BeyondMinikube @LostInBrittany
Conclusions And the point was? #JSC2019 #BeyondMinikube @LostInBrittany
Kubernetes is powerful It can make Developers’ and DevOps’ lifes easier #JSC2019 #BeyondMinikube @LostInBrittany
Different roles Each role asks for very different knowledge and skill sets #JSC2019 #BeyondMinikube @LostInBrittany
Most companies don’t need to operate the clusters As they don’t build and rack their own servers! #JSC2019 #BeyondMinikube @LostInBrittany
If you don’t need to build it, choose a certified managed solution You get the cluster, the operator get the problems #JSC2019 #BeyondMinikube @LostInBrittany
Do you want to try? Send me an email to get some vouchers… horacio.gonzalez@corp.ovh.com #JSC2019 #BeyondMinikube @LostInBrittany
Ces derniers mois Kubernetes est partout, en terme de buzz word on peut difficilement faire mieux. Et comme souvent lorsqu’un sujet est si populaire, vous avez des tutoriels, billets de blog et talks par milliers, expliquant comment bien démarrer sur Kubernetes. Tout va donc bien dans le meilleur des mondes, non ?
Et bien non, pour être honnête. Car l’immense majorité de ces tutoriels, articles et talks s’arrêtent juste après le Hello Kube, lorsque vous avez quelques applications tournant sur votre MiniKube sur le laptop. Et là, c’est pas la fin, mais à peine le principe…
Dans ce talk je vais parler de cet écart entre MiniKube et une infra de production, de l’intérêt des infrastructures Kubernetes managées, des pièges et du vendor locking, de comment arriver à faire assez confiance dans sa solution pour faire tourner du Kubernetes sur Kubernetes et d’autres sujets de ce type.
