基于 Jenkins 构建时，报错：’composer install’ returned a non-zero code: 255 的解决

1、Dockerfile 的代码如下：

FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php71:0.2.4

MAINTAINER wjtester@sobey.com

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

RUN chown -R nginx:nginx /sobey/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    cd /sobey/www/pcs-api && \
    composer install

2、基于 Jenkins 构建时，报错详细信息如下，如图1

3、编辑 Dockerfile，暂时取消 composer 相关，构建成功后，在 Docker 容器中运行 composer -V，无反应，如图2

FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php71:0.2.4

MAINTAINER wjtester@sobey.com

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

RUN chown -R nginx:nginx /sobey/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf

4、编辑 Dockerfile，编辑 php.ini 中的配置：open_basedir(新增 PHP 所能打开的文件的目录树 /usr/local/php/)、allow_url_fopen，如图3

图3

FROM registry-vpc.cn-beijing.aliyuncs.com/cmc/centos-nginx112-php71:0.2.4

MAINTAINER wjtester@sobey.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

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

RUN chown -R nginx:nginx /sobey/www/ && \
    rm -rf /etc/nginx/conf.d/status.conf && \
    chmod +x /usr/local/bin/composer && \
    cd /sobey/www/pcs-api && \
    composer install

5、基于 Jenkins 构建时，符合预期，如图4
