用opencloudos官方镜像制作自己的docker镜像

官方容器使用方法

拉取镜像

这个操作是使用容器的常规操作了，官方也都发布到了docker hub里面，直接拉取即可

<span class="token punctuation">[</span>root@lab101 /<span class="token punctuation">]</span><span class="token comment"># docker pull opencloudos/opencloudos:8.6</span>
<span class="token punctuation">[</span>root@lab101 /<span class="token punctuation">]</span><span class="token comment"># docker image ls</span>
docker.io/opencloudos/opencloudos   <span class="token number">8.6</span>                 85381566b97e        <span class="token number">7</span> days ago               <span class="token number">280</span> MB

启动容器

<span class="token punctuation">[</span>root@lab101 /<span class="token punctuation">]</span><span class="token comment"># docker run --name opencloudos  --net=host  --hostname=opencloudos  -dit   --privileged=true  opencloudos/opencloudos:8.6   /sbin/init</span>
bbe06493e7b2305b430c635c23b06b6eeca7d0df38ebfa6a9ab8428a39f1b11c

进入容器

<span class="token punctuation">[</span>root@lab101 /<span class="token punctuation">]</span><span class="token comment"># docker exec -it opencloudos /bin/bash</span>
bash-4.4<span class="token comment">#</span>

可以看到进入容器是显示的bash-4.4不是主机名
可以看到

bash-4.4<span class="token comment"># ls /root/</span>

root下面是空的
应该是要有下面的

<span class="token punctuation">[</span>root@centos8 /<span class="token punctuation">]</span><span class="token comment"># ls /root/.</span>
./             <span class="token punctuation">..</span>/            .bash_history  .bash_logout   .bash_profile  .bashrc        .cshrc         .tcshrc

检查常用包

bash-4.4<span class="token comment"># rpm -qa|grep hostname</span>
bash-4.4<span class="token comment"># rpm -qa|grep vi</span>
device-mapper-1.02.181-3.oc8.x86_64
device-mapper-libs-1.02.181-3.oc8.x86_64

发现vi和hostname命令都没加进去，这里基本的包还是保持比较好，这个在centos8的官方容器里面都做了保留

安装自己的环境

#根据自己的需要执行安装即可


yum install tar make libsodium-devel libmcrypt libmcrypt-devel mysql vim crontabs rsync git crontabs logrotate


yum install php-devel php-bcmath php-gd php-pdo_mysql php-mysqli php-posix
