Single-node Kubernetes Clusters Using K3s with Benefits of GitOps • Lasse Højgaard • GOTO 2021

This presentation was recorded at GOTO Copenhagen 2021. #GOTOcon #GOTOcph http://gotocph.com Lasse Højgaard - Cloud Architect & Software Pilot at Trifork @lassehjgaard3104 ORIGINAL TALK TITLE Lowering the Barriers to Entry for Kubernetes ABSTRACT The Kubernetes eco-system is quickly becoming the de facto way to run applications. The toolbox is chock-full of tools that can be hard to let go off once you’ve tried them. Large-scale Kubernetes deployments in the cloud or on-premises can be a daunting task to set up. Sometimes you can’t justify the cost of a managed Kubernetes cluster because the project is still in its infancy? What if you don’t need a highly-available multi-node cluster? Should you go back to running Docker containers on a simple VM? In this talk we will look at how single-node Kubernetes clusters using K3s can be a way to lower the barrier of entry for Kubernetes, while still getting the benefits of GitOps, rolling deployments, and mature monitoring solutions. We’ll also discuss next steps if you outgrow your single-node cluster [...] TIMECODES 00:00 Intro 02:20 Agenda 03:01 Act 1: Docker-compose up & echo done 11:14 Act 2: Trouble in paradise 14:57 Act 3: Is there something better & can we afford it? 23:25 Demo 41:10 Problems to solve 41:33 Where to go from here? 42:59 Outro Download slides and read the full abstract here: https://gotocph.com/2021/sessions/2000/lowering-the-barriers-to-entry-for-kubernetes RECOMMENDED BOOKS Thomas Vitale • Cloud Native Spring in Action • https://amzn.to/3355Zy0 Brendan Burns, Joe Beda & Kelsey Hightower • Kubernetes: Up and Running • http://amzn.to/31OAhB9 Burns, Villalba, Strebel & Evenson • Kubernetes Best Practices • https://amzn.to/3gBXRsr Sam Newman • Monolith to Microservices • https://amzn.to/2Nml96E Sam Newman • Building Microservices • https://amzn.to/3dMPbOs Ronnie Mitra & Irakli Nadareishvili • Microservices: Up and Running• https://amzn.to/3c4HmmL Mitra, Nadareishvili, McLarty & Amundsen • Microservice Architecture • https://amzn.to/3fVNAb0 Chris Richardson • Microservices Patterns • https://amzn.to/2SOnQ7h Adam Bellemare • Building Event-Driven Microservices • https://amzn.to/3yoa7TZ Dave Farley • Continuous Delivery Pipelines • https://amzn.to/3hjiE51 https://twitter.com/GOTOcon https://www.linkedin.com/company/goto- https://www.instagram.com/goto_con https://www.facebook.com/GOTOConferences #CloudNative #Cloud #Kubernetes #k8s #k3s #DevOps #ContinuousDelivery #CD #Testing #GitOps #Microservices #APIs #APIGateway #Observability #Testing #Docker #DockerCompose #CNCF #Flux #Helm #Kustomize #curl #SealedSecrets CHANNEL MEMBERSHIP BONUS Join this channel to get early access to videos & other perks: https://www.youtube.com/channel/UCs_tLP3AiwYKwdUHpltJPuA/join Looking for a unique learning experience?
