Docker 部署，将目录 sobey 修改为 mcloud，构建镜像时，报错：composer install returned a non-zero code: 255 的分析解决
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
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 ---> Running in a73905f2bdbc [91mDo not run Composer as root/super user! See https://getcomposer.org/root for details [0mThe command '/bin/sh -c 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' returned a non-zero code: 255 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
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 ---> Running in 28a2ad979c18 All settings correct for using Composer Warning: is_dir(): open_basedir restriction in effect.

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
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/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
