第一種制作鏡像方式: centos7.5+vim+net-tools+iproute+sshd

1. 啟動(dòng)新容器

   docker images查詢已存在的鏡像

   docker run -it --name "centos7.5" [存在的鏡像的ID]

2. 優(yōu)化yum源

   mv /etc/yum.repos.d/*.repo /tmp
   echo -e "[ftp]\nname=ftp\nbaseurl=ftp://10.0.0.100/pub/centos7\ngpgcheck=0">/etc/yum.repos.d/ftp.repo

3. 安裝必須軟件包

   yum install -y vim net-tools iproute openssh-* -y

4. 啟動(dòng)SSHD

   mkdir /var/run/sshd
   echo 'UseDNS no' >> /etc/ssh/sshd_config
   sed -i -e '/pam_loginuid.so/d' /etc/pam.d/sshd
   echo 'root:123456' | chpasswd
   /usr/bin/ssh-keygen -A
   /usr/sbin/sshd -D

   注意: 以上操作做完之后,會(huì)一直不退出,需要用以下命令退回到宿主機(jī),并不關(guān)閉容器
   ctrl+p+q

5. 制作鏡像

   docker commit ['step 1 name'] {'new name'}:{new tag}

   eg: docker commit centos7.5 huojibufei/centos7_sshd:v1

第二種制作鏡像方式: centos7.5+vim+net-tools+iproute+sshd

1. cd /opt/dockerfile

2. vim dockerfile

FROM centos:7.5.1804
RUN mv /etc/yum.repos.d/*.repo /tmp
RUN echo -e "[ftp]\nname=ftp\nbaseurl=ftp://10.0.0.100/pub/centos7\ngpgcheck=0">/etc/yum.repos.d/ftp.repo
RUN yum install -y openssh-server
RUN yum install -y openssh-clients
RUN yum install net-tools* -y
RUN yum install iproute-* -y
RUN mkdir /var/run/sshd
RUN echo 'UseDNS no' >> /etc/ssh/sshd_config
RUN sed -i -e '/pam_loginuid.so/d' /etc/pam.d/sshd
RUN echo 'root:123456' | chpasswd
RUN /usr/bin/ssh-keygen -A
EXPOSE 22
CMD ["/usr/sbin/sshd", "-D"]

3. docker build -t "huoji/centos7_sshd:v1" /opt/dockerfile

制作私有倉(cāng)庫(kù)

1. 配置私有倉(cāng)庫(kù)

   1. docker run -d -p 5000:5000 --restart=always --name registry -v /opt/Registry:/var/lib/registry registry

      ps:-v參數(shù)指定持久化地址 系統(tǒng)數(shù)據(jù)卷:容器的數(shù)據(jù)卷

   2. vim /etc/docker/daemon.json

      {
         "registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"],
         "insecure-registries": ["10.0.0.100:5000"]
      }

3. systemctl restart docker

4. 使用本地鏡像

   1. 制作本地鏡像并push到

      docker tag nginx 10.0.0.100:5000/huoji/nginx:v1

      docker images

      docker push 10.0.0.100:5000/huoji/nginx:v1
