在 jenkins 中构建镜像时，报错：fatal Could not read from remote repository 的解决

1、在 jenkins 中构建镜像时，报错：fatal: Could not read from remote repository.。虽然 Packagist 镜像地址已经切换为阿里云：https://mirrors.aliyun.com/composer/ 。查看 Dockerfile。如图1

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/cmcp-api && \
    composer install

2、最终决定将 /vendor 目录添加至 Git 仓库：# /vendor，编辑 .gitignore

# Env
/.env

# Composer
# /vendor
composer.phar

# JS
node_modules
spa/npm-debug.log
spa/yarn-error.log


# IDE
.idea
nbproject
.buildpath
.project
.settings

# windows thumbnail cache
Thumbs.db

# Mac DS_Store Files
.DS_Store

# phpunit
phpunit.phar
/phpunit.xml

# Vagrant
/.vagrant

# Tests
tests/codeception/*/_support/_generated/*

3、编辑 Dockerfile，删除与 composer 相关的 4 行命令。构建成功。如图3

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