初投稿で慣れない部分が多々ありますが、よろしくお願いします。
前提・実現したいこと
Win10 proでdockerを用いてcentos7の仮想環境を構築したい。
発生している問題・エラーメッセージ
centos7のコンテナを立ち上げて、yumでhttpdをインストールしようとすると…
[root@5522cb6c9be4 /]# yum -y install httpd Loaded plugins: fastestmirror, ovl Loading mirror speeds from cached hostfile Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), 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=<repoid> ... 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 <repoid> or subscription-manager repos --disable=<repoid> 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=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
###エラー画面に至るまでの経緯
centosのimageをpullする。
PS C:\WINDOWS\System32> docker pull centos:latest
centosのコンテナを立ち上げる。
PS C:\WINDOWS\System32> docker run --privileged -d --name centos centos /sbin/init
bashでcentosコンテナ内のコマンド画面を開く。
docker exec -it centos /bin/bash
ここでエラー発生。
[root@5522cb6c9be4 /]# yum -y install httpd
試したこと
docker学習中の初心者なので、エラーへの対応が分からず困っています。
最後に
経緯の説明など、全体的に説明不足で申し訳ありません。
分かる方がいれば教えていただきたいです。
