Preparation¶
- A node with CPU > 8 cores, memory > 12 GB, disk > 100 GB.
- Ensure that the node can access the Internet.
Run the following script to check the system resources and network connectivity:
set -e
if [ $(free -g|grep Mem | awk '{print $2}') -lt 12 ]; then (echo "insufficient memory! (should >=12G)";); fi
if [ $(grep 'processor' /proc/cpuinfo |sort |uniq |wc -l) -lt 8 ]; then (echo "insufficient CPU! (should >=8C)";); fi
if [ $(df -m / |tail -n 1 | awk '{print $4}') -lt 30720 ]; then (echo "insufficient free disk space of root partition!(should >=30G)";); fi
ping daocloud.io -c 1 &> /dev/null || ( echo "no connection to internet! abort.")
echo "precheck pass.."
Expected output is something like:
Install Docker¶
Note
- If you have installed Docker v1.18+, skip this step.
- If you have Podman on your node but not Docker, you still need to install Docker. This is caused by a known bug: although Podman can start kind, there will be a problem of insufficient file handles and IP mismatch.
set -e
if [ -x "$(command -v docker )" ] ;then
echo "docker already installed : version = "$(docker -v);
else
echo "docker not found, please install it first."
fi
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo service docker start
sudo systemctl enable docker
sudo yum install -y wget
set -e
if [ -x "$(command -v docker )" ] ;then
echo "docker already installed : version = "$(docker -v);
else
echo "docker not found, please install it first."

sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository --yes "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get -y update
sudo apt-get -y install docker-ce
sudo apt-get -y install wget
sudo service docker start
sudo systemctl enable docker
Install kind cluster¶
-
Download the binary package of kind.
-
Check the kind version.
The expected output is like:
-
Modify the
kind_cluster.yaml
to make it applicable in your environment.Expose the internal port
32088
to port 8888 (customizable) for external communication. The configuration file example is as follows: -
Create a Kubernetes cluster of v1.25.3, named (for example)
fire-kind-cluster
.kind create cluster --image release.daocloud.io/kpanda/kindest-node:v1.25.3 --name=fire-kind-cluster --config=kind_cluster.yaml
The expected output is like:
-
Check the newly created cluster.
The expected output is like:
