离线安装 KubeSphere 2.1.1 与 Kubernetes

fnag_huna

Cauchy 是CentOS Linux release 7.8.2003 (Core)

Cauchy

fnag_huna

那应该是不支持的，可以尝试把Repos/centos-7.7-amd64.iso改成centos-7.8-amd64.iso试试。
如果不行的话就装v3.0.0吧。

fnag_huna

Cauchy 好的，谢谢！

fnag_huna

Cauchy 改成7.8以后成功开始安装了，非常感谢！但是现在出现了这样的状况，是在拉镜像拉不下来吗？我用的代理，wget能通网，但不知道为什么这里的镜像无法拉取，望解惑
又仔细看了一眼地址，感觉是在本地拉取的镜像？那为何无法拉取呢？

Cauchy

fnag_huna
可以执行docker info看下docker的配置，是不是这个本地仓库的地址没有加到docker的insecure_registries中。

fnag_huna

Cauchy 看了一下，里面是有本地仓库地址的：Insecure Registries: 192.168.2.32:5000 127.0.0.0/8这是什么原因呢

fnag_huna

Cauchy 顺带一提，我现在安装的是 all-in-one 单节点模式的，之前尝试安装多节点时出现了这样的情况
我的hosts.ini配置是这样的：
请问是哪里出问题了？

Cauchy

fnag_huna
先docker ps | grep registry检查下这个仓库服务是否正常，然后push个镜像试下是否能成功。

fnag_huna

Cauchy push了一个镜像，果然无法成功，一直在retrying

fnag_huna

Cauchy 查看了一下docker的日志，报的错也让人找不到头绪。。。

Cauchy

fnag_huna
看起来是registry服务不正常，可以重启下这个容器试试。
上边那个ssh连接不到远程机器的问题应该是机器上留存了旧的连接信息。可以把_{/.ssh/known_hosts删掉试试。}

fnag_huna

Cauchy 谢谢您，帮助了我很多。前面几次bug调试无果，目前尝试从centos7.7安装kubesphere了，期待能成功吧。。。

nan 有解决么，我刚好也碰到这个问题
