A Fresh Look for the Socket Dashboard
We’ve redesigned the Socket dashboard with simpler navigation, less visual clutter, and a cleaner UI that highlights what really matters.
github.com/rancher/k3d
k3s is the lightweight Kubernetes distribution by Rancher: rancher/k3s
This repository is based on @zeerorg's zeerorg/k3s-in-docker, reimplemented in Go by @iwilltry42 in iwilltry42/k3d, which is now rancher/k3d.
You have several options there:
use the install script to grab the latest release:
wget -q -O - https://raw.githubusercontent.com/rancher/k3d/master/install.sh | bash
curl -s https://raw.githubusercontent.com/rancher/k3d/master/install.sh | bash
use the install script to grab a specific release (via TAG
environment variable):
wget -q -O - https://raw.githubusercontent.com/rancher/k3d/master/install.sh | TAG=v1.3.4 bash
curl -s https://raw.githubusercontent.com/rancher/k3d/master/install.sh | TAG=v1.3.4 bash
Use Homebrew: brew install k3d
(Homebrew is avaiable for MacOS and Linux)
Grab a release from the release tab and install it yourself.
Via go: go install github.com/rancher/k3d
(Note: this will give you unreleased/bleeding-edge changes)
or...
go get -u github.com/rancher/k3d
make build

Example Workflow: Create a new cluster and use it with kubectl
(Note: kubectl
is not part of k3d
, so you have to install it first if needed)
k3d create
to create a new single-node cluster (docker container)export KUBECONFIG=$(k3d get-kubeconfig)
to make kubectl
to use the kubeconfig for that clusterkubectl get pods --all-namespaces
k3d delete
to delete the default clusterIf you want to access your services from the outside (e.g. via Ingress), you need to map the ports (e.g. port 80 for Ingress) using the --publish
flag (or aliases).
