1、docker安装

安装docker

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

更换docker目录

mkdir /data/docker
echo "/data/docker /var/lib/docker none bind 0 0" >>/etc/fstab
systemctl stop docker
rsync -aXS /var/lib/docker/. /data/docker/
mount -a
systemctl start docker

2、docker-compose安装

下载docker-compose可执行文件，上传到服务器上
https://github.com/docker/compose/releases/tag/v2.14.2

重新命名

mv docker-compose-linux-x86_64 docker-compose
sudo cp docker-compose /usr/local/bin/
cd /usr/local/bin/
sudo chmod 777 docker-compose
docker-compose version

3、K3s安装

3.1 k3s与install.sh文件准备

• k3s文件下载
• install.sh文件下载
  以v1.26.0+k3s1为例进行安装
  k3s下载地址，选择k3s文件上传到服务器

下载安装脚本install.sh

curl https://raw.githubusercontent.com/rancher/k3s/master/install.sh -o install.sh

给权限

sudo chmod 777 k3s
sudo chmod 777 install.sh

把文件复制到 /usr/local/bin/k3s

sudo cp k3s /usr/local/bin/k3s

3.2 k3s安装步骤

安装k3s

INSTALL_K3S_SKIP_DOWNLOAD=true INSTALL_K3S_EXEC=--docker ./install.sh --disable=traefik

查看k3s服务状态。
sudo systemctl status k3s

卸载命令
/usr/local/bin/k3s-uninstall.sh

4、查看k3s部署状态

查看容器状态：

sudo kubectl get pods -A
