kubectlのインストールとセットアップ-Kubernetes

フォローしようとしています kubectlのインストールとセットアップ-Kubernetes 、それでもエラーが発生し続けます：

# 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.

また、curlを使用して同じURLにアクセスしようとしましたが、次のようになりました。

# 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.

どういうわけかyumのリポジトリファイルで-k/--insecureを使用する方法はありますか？

お知らせ下さい。

Tls接続を傍受する何らかのプロキシがあるようです。

ただし、yumで証明書チェックをバイパスすることは可能です。この行をKubernetesリポジトリ設定に配置できます。

sslverify = 0

それが役に立てば幸い。

kubernetes.repoファイルから次の2行を削除します。

gpgcheck=1
repo_gpgcheck=1

それは私のために働いた。これらは、ダウンロード後にパッケージの署名を確認します。
