Replacing need for Docker Desktop

Replacing need for Docker Desktop

Docker for Desktop is a great solution for local development with docker and Kubernetes on Mac and Windows and became standard de-facto. Unfortunately Docker Inc recently decided to make Docker for Desktop a paid solution for enterprises with 250 +. This presentation go over possible alternatives that can provide workaround for you organization until all required decision has been made how to go forward

Transcript

  1. Local Dev environment Must have: • Build Docker Images (Docker

    Engine) # docker build -t image_name . • Run Docker Containers # docker run image_name • Deploy to Kubernetes # kubectl create deployment –image=image_name [Optional] Nice to have: • Able to run Docker Compose # docker-compose up . • Scan Images # docker scan image • Nice UI
  2. Docker for Desktop: Pros and Cons • Multi platform •

    UI • Great Dev Experience • Paid product for enterprise • Frequent updates • High CPU usage • Little k8s control
  3. [Mac] Containers without Docker: Colima • Colima Container runtimes on

    macOS (and Linux) with minimal setup ◦ Intel and M1 Macs support ◦ Simple CLI interface ◦ Docker and Containerd support ◦ Port Forwarding ◦ Volume mounts ◦ Kubernetes (hidden K3s) ◦ Fully replace Docker-for-Desktop (but no UI)
  4. [Mac] Containers without Docker: Colima brew install colima # optional,

    not needed for containerd brew install docker # default using Docker runtime colima start # start kubernetes local cluster colima start --with-kubernetes # remove docker completely colima start --runtime containerd --with-kubernetes
  5. Using minikube as Docker Desktop Replacement # Install Docker CLI

    (https://download.docker.com/ or `brew install docker`) # Install Minikube (https://minikube.sigs.k8s.io/docs/start/) # Install HyperKit (https://minikube.sigs.k8s.io/docs/drivers/hyperkit/) minikube start --driver hyperkit # will be auto-detected Or minikube start --container-runtime=docker --no-kubernetes minikube docker-env • Minikube: local Kubernetes focusing on making it easy to learn and develop for Kubernetes. ◦ Official Kubernetes tool maintained by K8s SIGs ◦ Supports the latest Kubernetes release ◦ Cross-platform (Linux, macOS, Windows) ◦ Multiple container runtimes (CRI-O, containerd, docker) ◦ Can use minikube as a Docker Desktop Replacement
  6. Local Cluster: Kind https://kind.sigs.k8s.io/ Kind stands for Kubernetes in Docker.

    It’s a tool to create lightweight Kubernetes clusters using Docker container “nodes”. • Official Kubernetes tool maintained by K8s SIGs • It can be used to deploy Local K8s cluster or for CI • Support ingress / LB (with some tuning) • Support deployment of multiple clusters / versions • Supports deployment of single or multi node clusters
  7. Containers without Docker Engine: PodMan • Podman is the container

    Swiss-Army knife maintained by RedHat ◦ Replaces Docker-For-Desktop, Docker Engine, Docker CLI ◦ Works for Windows, Mac, Linux ◦ Podman version 3.4+ now support M1 Apple Macs ◦ Rootless mode provide more security ◦ Multiple image formats including the OCI and Docker image ◦ Container image management (managing image layers, overlay filesystems, etc) ◦ However doesn’t provide Kubernetes cluster!!! So use Kind
  8. # kubecolor # kubie # k9s kubectx + kubens Setup

    your Shell for Kubernetes and get produktive
  9. Step by step how to setup Mac with K8s Productivity
