1、Docker 部署，在 Jenkins 上构建镜像时，报错：composer install returned a non-zero code: 255，如图1



Step 7 : RUN chown -R nginx:nginx /mcloud/www/ &&     rm -rf /etc/nginx/conf.d/status.conf &&     composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ &&     cd /mcloud/www/pcs-api &&     composer install

Build step 'Docker Build and Publish' marked build as failure
Finished: FAILURE

2、Dockerfile 执行命令失败的代码如下



FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php72:0.1.12

MAINTAINER wangqiang@chinamcloud.com

RUN sed -i 's/open_basedir = .\/:\/mcloud:\/tmp:\/data:\/webtv/;open_basedir = .\/:\/mcloud:\/tmp:\/data:\/webtv:\/usr\/local\/php/g' /usr/local/php/etc/php.ini && \
    sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
    sed -i 's/disable_functions = exec,system,passthru,shell_exec,escapeshellarg,escapeshellcmd,proc_close,proc_open,dl,popen,show/disable_functions = system,shell_exec,escapeshellarg,escapeshellcmd,dl,popen,show/g' /usr/local/php/etc/php.ini

COPY code /mcloud/www/pcs-api
COPY code/build/c_files/ /

RUN chown -R nginx:nginx /mcloud/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ && \
    cd /mcloud/www/pcs-api && \
    composer install

3、编辑 Dockerfile，构建成功，可见失败的原因在于：composer install



RUN chown -R nginx:nginx /mcloud/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ && \
    cd /mcloud/www/pcs-api

4、编辑 Dockerfile，查看 composer 的版本信息与全局配置选项的列表



RUN chown -R nginx:nginx /mcloud/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ && \
    cd /mcloud/www/pcs-api && \
    composer --version && \
    composer config --global --list

5、在 Jenkins 上构建镜像时，仍然报错：composer install returned a non-zero code: 255，可见，composer 相关的命令是执行不了的，不仅是 composer install，如图2

6、编辑 Dockerfile，下载 Composer 的可执行文件，局部安装



RUN chown -R nginx:nginx /mcloud/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    cd /mcloud/www/pcs-api && \
    curl -sS https://getcomposer.org/installer | php && \
    php composer.phar install

7、在 Jenkins 上构建镜像时，报错：php composer.phar install returned a non-zero code: 1，如图3



RUN chown -R nginx:nginx /mcloud/www/ &&     rm -rf /etc/nginx/conf.d/status.conf &&     cd /mcloud/www/pcs-api &&     curl -sS https://getcomposer.org/installer | php &&     php composer.phar install

Finished: FAILURE

8、醒悟过来，原因在于 Dockerfile 文件，之前执行了批量替换，将 sobey 批量替换为 mcloud，决定仅替换其中的 3 处，其余 2 处的 mcloud 还原为 sobey，如图4



FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php72:0.1.12

MAINTAINER wangqiang@chinamcloud.com

RUN sed -i 's/open_basedir = .\/:\/sobey:\/tmp:\/data:\/webtv/;open_basedir = .\/:\/sobey:\/tmp:\/data:\/webtv:\/usr\/local\/php/g' /usr/local/php/etc/php.ini && \
    sed -i 's/allow_url_fopen = Off/allow_url_fopen = On/g' /usr/local/php/etc/php.ini && \
    sed -i 's/disable_functions = exec,system,passthru,shell_exec,escapeshellarg,escapeshellcmd,proc_close,proc_open,dl,popen,show/disable_functions = system,shell_exec,escapeshellarg,escapeshellcmd,dl,popen,show/g' /usr/local/php/etc/php.ini

COPY code /mcloud/www/pcs-api
COPY code/build/c_files/ /

RUN chown -R nginx:nginx /mcloud/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/ && \
    cd /mcloud/www/pcs-api && \
    composer install

9、Docker 部署，在 Jenkins 上构建镜像成功，后续有待于基础镜像升级之后，才能够全部执行替换了的。如图5
