报错信息

[preflight] Running pre-flight checks
	[WARNING SystemVerification]: this Docker version is not on the list of validated versions: 20.10.17. Latest validated version: 18.09

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java

解决

报错信息可以看出跟docker的版本有关系，意思是：此 Docker 版本不在已验证版本列表中：20.10.17。最新验证版本：18.09

分别查看docker和k8s的版本

kubectl version
docker version

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java

k8s与docker的兼容关系图，所以需要降低docker的版本到18.09以下

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java

降低docker版本到18.09

查看当前仓库支持的docker版本

yum list docker-ce --showduplicates | sort -r

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java
选择18.09的版本，降级到18.06版本会报错

语法： yum downgrade --setopt=obsoletes=0 -y docker-ce- ${version} docker-ce-selinux-$ {version}

降低docker版本到18.06.3.ce-3.el7

yum downgrade --setopt=obsoletes=0 -y docker-ce-18.09.9-3.el7 docker-ce-cli-18.09.9-3.el7 containerd.io

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java
查看降级后版本

systemctl start docker
docker version

[warning systemverification]: this docker version is not on the list of vali,容器&云原生,docker,容器,java 文章来源地址https://www.toymoban.com/news/detail-620105.html
