Installation

curl -s https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash

Create K3D clusters

dev:

k3d cluster create --config=./k3d/dev-config.yaml

dev-custom (istio):

k3d cluster create --config=./k3d/dev-config-custom.yaml

test:

k3d cluster create --config=./k3d/stage-config.yaml

prod:

k3d cluster create --config=./k3d/prod-config.yaml

If you need use specific version please visit here

Create K3D cluster using utils

By default dev-cluster will be created although not given cluster name!

Create:

$ ./utils/k3d-wrapper.sh -c
🔥 Creating Kubernetes Cluster: dev-cluster \
✅ Cluster: dev-cluster sucessfully created

List:

$ ./utils/k3d-wrapper.sh -l
👍 Cluster: dev-cluster exist!
---------------------------------------------
NAME          SERVERS   AGENTS   LOADBALANCER
dev-cluster   1/1       3/3      true
---------------------------------------------

Delete:

$ ./utils/k3d-wrapper.sh -d
⚡ Cluster: dev-cluster exists and will be deleted /
✅ Cluster: dev-cluster sucessfully deleted

Unexisting config file:

$ ./utils/k3d-wrapper.sh -c pprod-cluster
👀 Kubernetes cluster config: pprod-cluster.conf does not exist! Please check k3d dir! 

Deploy cluster with particular configuration

Below configuration contains istio deployment. Be patient this process can take a while!

$ ./utils/k3d-wrapper.sh -c dev-cluster-custom
🔥 Creating Kubernetes Cluster: dev-cluster-custom |
✅ Cluster: dev-cluster-custom sucessfully created

$ ./utils/k3d-wrapper.sh -l dev-cluster-custom
👍 Cluster: dev-cluster-custom exist!
