Docker镜像创build抛出“没有这样的文件或目录，访问'/ node_modules / sails'”当dockerizing一个sails.js应用程序
以下是Dockerfile
FROM node:latest RUN npm install -g sails@0.12.13 ADD . / ./ RUN npm install EXPOSE 80 CMD (sails lift)
使用以下日志创build映像失败：

即使我尝试创build目录，或使用以下命令将权限更改为777： RUN (mkdir -p /node_modules/sails; chmod 777 /node_modules/sails)
它仍然失败，同样的错误：

任何指针如何我可以debugging呢？
将您的Dockerfile更改为下面
FROM node:latest RUN npm install -g sails@0.12.13 WORKDIR /usr/app COPY package.json ./ RUN npm install COPY . ./ EXPOSE 80 CMD sails lift
你应该首先复制package.json ，然后执行npm install然后复制代码。 你的ADD语句也是错误的。 有一个额外的空间
接下来确保你有忽略node_modules的.dockerignore。 否则node_modules将被复制操作覆盖
