쿠버네틱스 강의 듣고 있는데 계속 에러가 떠서 뭐 할 수가 없네요 2일간 구글링 해봤는데 안되서 여기다가 질문 날립니다.

 

아래는 쿠버넷 에러나는 곳만 발췌한 부분입니다.

   w3-k8s-1.25.0: Loaded plugins: fastestmirror
    w3-k8s-1.25.0: Determining fastest mirrors

    w3-k8s-1.25.0:  * extras: mirror.navercorp.com
    w3-k8s-1.25.0:  * updates: mirror.navercorp.com
    w3-k8s-1.25.0: https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/repomd.xml: [Errno 14] curl#60 - "The certificate issuer's certificate has expired. Check your system date and time."
    w3-k8s-1.25.0: Trying other mirror.
    w3-k8s-1.25.0: It was impossible to connect to the CentOS servers.
    w3-k8s-1.25.0: This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
    w3-k8s-1.25.0: or a transparent proxy that tampers with TLS security, or an incorrect system clock.
    w3-k8s-1.25.0: You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errors
    w3-k8s-1.25.0: If above article doesn't help to resolve this issue please use https://bugs.centos.org/.
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:  One of the configured repositories failed (Kubernetes),
    w3-k8s-1.25.0:  and yum doesn't have enough cached data to continue. At this point the only
    w3-k8s-1.25.0:  safe thing yum can do is fail. There are a few ways to work "fix" this:
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:      1. Contact the upstream for the repository and get them to fix the problem.
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:      2. Reconfigure the baseurl/etc. for the repository, to point to a working
    w3-k8s-1.25.0:         upstream. This is most often useful if you are using a newer
    w3-k8s-1.25.0:         distribution release than is supported by the repository (and the
    w3-k8s-1.25.0:         packages for the previous distribution release still work).
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:      3. Run the command with the repository temporarily disabled
    w3-k8s-1.25.0:             yum --disablerepo=kubernetes ...
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:      4. Disable the repository permanently, so yum won't use it by default. Yum
    w3-k8s-1.25.0:         will then just ignore the repository until you permanently enable it
    w3-k8s-1.25.0:         again or use --enablerepo for temporary usage:
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:             yum-config-manager --disable kubernetes
    w3-k8s-1.25.0:         or
    w3-k8s-1.25.0:             subscription-manager repos --disable=kubernetes
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:      5. Configure the failing repository to be skipped, if it is unavailable.
    w3-k8s-1.25.0:         Note that yum will try to contact the repo. when it runs most commands,
    w3-k8s-1.25.0:         so will have to try and fail each time (and thus. yum will be be much
    w3-k8s-1.25.0:         slower). If it is a very temporary problem though, this is often a nice
    w3-k8s-1.25.0:         compromise:
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0:             yum-config-manager --save --setopt=kubernetes.skip_if_unavailable=true
    w3-k8s-1.25.0: 
    w3-k8s-1.25.0: failure: repodata/repomd.xml from kubernetes: [Errno 256] No more mirrors to try.
    w3-k8s-1.25.0: https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/repomd.xml: [Errno 14] curl#60 - "The certificate issuer's certificate has expired. Check your system date and time."
