Question

以下是Dockerfile

FROM node:latest

RUN npm install -g sails@0.12.13

ADD . / ./
RUN npm install

EXPOSE 80

CMD (sails lift)

图像创建失败，并显示以下日志：

即使我尝试创建目录，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)

它仍然失败并出现同样的错误：

Docker版本：17.06.2-ce-mac27（19124）

关于我如何调试它的任何指针？

Answer 1

将Dockerfile更改为

以下

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

您应该先复制package.json并执行do npm安装，然后复制代码。您的ADD声明也是错误的。有一个额外的空间

接下来请确保您.dockerignore忽略node_modules。其他node_modules将被复制操作

覆盖

Docker图像创建抛出＆＃34;没有这样的文件或目录，访问＆＃39; / node_modules / sails＆＃39;＆＃34; dockerizing sails.js应用程序时
