kubespray-offline 下载并离线部署 kubernetes 自定义版本

kubespray-offline v2.21.0-0 默认部署 kubernetes 版本为 v1.25.6

我们以自定义部署 kubernetes 版本 v1.24.10为例。

• 下载：https://github.com/tmurakam/kubespray-offline/releases/tag/v2.21.0-0

unzip v2.21.0-0.zip
cd kubespray-offline-2.21.0-0

在下载介质之前需要安装：

• run install-docker.sh to install Docker CE.
• run install-containerd.sh to install containerd and nerdctl.
• Set docker environment variable to /usr/local/bin/nerdctl in config.sh.

docker 与 containerd 选择其一即可：

./install-docker.sh

安装成功后，下载介质执行：
暂时注释掉部分执行脚本

cat download-all.sh
#!/bin/bash

run() {
    echo "=> Running: $*"
    $* || {
        echo "Failed in : $*"
        exit 1
    }
}

source ./config.sh

run ./install-docker.sh
run ./precheck.sh
run ./prepare-pkgs.sh
run ./prepare-py.sh
run ./get-kubespray.sh
if $ansible_in_container; then
    run ./build-ansible-container.sh
else
    run ./pypi-mirror.sh
fi
#run ./download-kubespray-files.sh
#run ./download-additional-containers.sh
#run ./create-repo.sh
#run ./copy-target-scripts.sh

echo "Done."

./download-all.sh

执行结束后修改：

#修改下载k8s介质版本
$ vim cache/kubespray-2.21.0/roles/kubespray-defaults/defaults/main.yaml
....
kube_version: v1.25.6
.....


$ vim cache/kubespray-2.21.0/inventory/local/group_vars/k8s_cluster/k8s-cluster.yml
...
kube_version: v1.24.10
...

其他步骤参考：

• Kubespray v2.21.0 离线部署 Kubernetes v1.25.6 集群

在执行部署修改如下：

#修改部署k8s介质版本
vi /root/kubespray-offline-2.21.0-0/outputs/kubespray-2.21.0、inventory/local/group_vars/k8s_cluster/k8s-cluster.yml
...
kube_version: v1.24.10
...

# Example  
$ ansible-playbook -i inventory/local/inventory.ini --become --become-user=root cluster.yml
