CentOS8.4.2105 和 OpenEuler 20.03 下 C++ 编译环境容器镜像构建

CentOS7.x 支持的 gcc 和 g 版本太低，使用 CentOS 8.x 进行替换，但在实际操作的过程中，使用yum进行依赖更新，出现报错，写此文以记录。

代码语言：javascript复制

FROM centos:8.4.2105

RUN set -eux; 
    sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*; 
    sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*; 
    yum clean all; 
    yum makecache; 
    yum -y install gcc 
                   gcc-c   
                   gdb 
                   make 
                   cmake; 
    yum clean all; 
    yum makecache
    
COPY [ "ninja", "/usr/local/bin" ]


FROM scratch

COPY --from=0 / /

ENV TZ="Asia/Shanghai" 
    LANG="zh_CN.UTF-8"

CMD [ "/bin/bash" ]

顺便把 openEuler 的 C 构建镜像的 Dockerfile 也写一下：

代码语言：javascript复制

FROM openeuler:20.03

RUN set -eux; 
    yum -y install bc 
				   gcc 
                   gcc-c   
                   gdb 
                   make 
                   cmake; 
    yum clean all; 
    yum makecache


FROM scratch

COPY --from=0 / /

ENV TZ="Asia/Shanghai" 
    LANG="zh_CN.UTF-8"

CMD [ "/bin/bash" ]

运行 ssh 服务的 Dockerfile：

代码语言：javascript复制

FROM centos:8.4.2105

COPY [ "docker-entrypoint.sh", "/usr/local/bin" ]

RUN set -eux; 
    sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*; 
    sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*; 
    echo "root:develop" | chpasswd; 
    yum -y install gcc 
                   gcc-c   
                   gdb 
                   make 
                   cmake 
                   openssh-server 
                   rsync; 
    ssh-keygen -A; 
    yum clean all; 
    yum makecache;  
    chmod  x /usr/local/bin/*; 
    rm -f /run/nologin; 
    rm -f /root/{anaconda-ks.cfg,anaconda-post.log,original-ks.cfg}; 
    mkdir /var/run/sshd

FROM scratch

COPY --from=0 / /

ENV TZ="Asia/Shanghai" 
    LANG="zh_CN.UTF-8" 
    SSH_USERNAME="develop" 
    SSH_PASSWD="develop" 
    SSH_UID="1000" 
    SSH_GROUP="develop" 
    SSH_GID="1000"

ENTRYPOINT [ "docker-entrypoint.sh" ]

EXPOSE 22

CMD [ "/usr/sbin/sshd", "-D" ]

docker-entrypoint.sh 如下：

代码语言：javascript复制

#!/bin/bash

set -eux
gcc -v
g   -v
gdb -v
make -v
cmake -version
groupadd -g ${SSH_GID} ${SSH_GROUP}
useradd -d /home/${SSH_USERNAME} -m -c "Develop environment." -u ${SSH_UID} -g ${SSH_GID} -s /bin/bash ${SSH_USERNAME}
echo "${SSH_USERNAME}:${SSH_PASSWD}" | chpasswd

exec "$@"

容器启动命令：

代码语言：javascript复制

docker run -d --restart always --hostname develop -e SSH_UID=`id -u` -e SSH_GID=`id -g` -e SSH_USERNAME=`whoami` -e SSH_PASSWD="dev123" -e SSH_GROUP=`id -g -n` --name develop -v ${HOME}/workspace:/home/`whoami` -p 2024:22 centos:sshd

容器镜像服务 centos linux
