|
go build -o k3s

|
go build -o kubectl ./cmd/kubectl

|
|
|
Run
|

|
sudo curl -fL -o /usr/local/bin/runc https://github.com/opencontainers/runc/releases/download/v1.0.0-rc5/runc.amd64
|
|
sudo chmod +x /usr/local/bin/runc
|
|
|
|
curl -fsL https://github.com/containerd/containerd/releases/download/v1.1.1/containerd-1.1.1.linux-amd64.tar.gz | sudo tar xvf /usr/src/containerd.tgz -C /usr/local/bin bin/ --strip-components=1
|
|
|
|
# Some CNI
|
|
sudo mkdir -p /opt/cni/bin
|
|
curl -fsL https://github.com/containernetworking/plugins/releases/download/v0.7.1/cni-plugins-amd64-v0.7.1.tgz | sudo tar xvzf - -C /opt/cni/bin ./loopback
|
|
|
|
sudo containerd &
|
|
```

Run Kubernetes
|
|
|
|
```bash
|
|
# Server
|
|
./k3s

|
# Agent (If doing this on another host copy the ./data folder)
|
|
sudo ./k3s agent
|
|
|
|
# Install Networking
|
|
export KUBECONFIG=./data/cred/kubeconfig.yaml
|
|
curl -s "https://cloud.weave.works/k8s/net?k8s-version=$(./kubectl version | base64 | tr -d '\n')" | sed 's!rbac.authorization.k8s.io/v1beta1!rbac.authorization.k8s.io/v1!g' | ./kubectl apply -f -

Your kubeconfig file is in `./data/cred/kubeconfig.yaml`

Enjoy.
