安装并设置 kubectl - Kubernetes

我正在尝试跟随安装并设置 kubectl - Kubernetes，但仍然出现错误：

# yum --quiet install kubectl
https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/repomd.xml: [Errno 14] curl#60 - "Peer's Certificate issuer is not recognized."
Trying other mirror.
It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.



 One of the configured repositories failed (Kubernetes),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=kubernetes ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable kubernetes
        or
            subscription-manager repos --disable=kubernetes

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=kubernetes.skip_if_unavailable=true

failure: repodata/repomd.xml from kubernetes: [Errno 256] No more mirrors to try.
https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/repomd.xml: [Errno 14] curl#60 - "Peer's Certificate issuer is not recognized."

我也尝试使用curl访问相同的 URL 并得到以下结果：

# curl https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/repomd.xml
curl: (60) Peer's Certificate issuer is not recognized.
More details here: http://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

有没有办法以-k/--insecure某种方式使用 yum 的 repo 文件？

请指教。

答案1

看起来您有某种拦截您的 tls 连接的代理。

但是，可以绕过 yum 中的证书检查，您可以将此行放入 Kubernetes repo 配置中：

sslverify = 0

希望能帮助到你。

答案2

从文件中删除以下两行kubernetes.repo：

gpgcheck=1
repo_gpgcheck=1

它对我有用。下载后会验证软件包签名。

答案3

解决了！您也可以在 kubernetes.repo 文件中通过以下方式绕过此问题：repo_gpgcheck到：

repo_gpgcheck=0
