定位:定义和运行多F x Q m { 5 )个DockeE r g ? 0 f Zr容器的应用。

我为什么要使# m V M x R用它,主要是因为它能够更快捷的编排l . 8 ! N U 6我的容器,且使用yml启动容器非常快捷。(暂时还没深入到K8s,大佬勿喷。。)


想安装docke0 4 : U Q E -r-compose那肯定要到官方文档I { Y k D安装靠谱啦!

safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contac/ ~ i e 8 Y C ct the upstream for the r2 H C , * 8 t )epu E m t A q Y /ository and get them to fix the problem.8 g U | ~ T A X Z
2. Reconfigure thR ; 2 6e baseurl/etA , Xc. for the repository, to point to a worD O t n T V @king
upstream. This is most often useful if you are using a newer
distribution release than is supported by3 : * th$ | l fe repository (and the
packages for the previous distribution release still work).
3. Run tU 8 V V _ :he command with the repository temporarily disabled
yum --diY % l E Ssablerepo=<repoid> ...
4. Disa3 j /ble the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanenr )  J ptly enable it

5. Configure the failing repository to be skipped, if it is unavailable.
Note that yuE N )m will try to contact the repo. when it runs most commands,
