Question

我正在尝试在AWS EC2中创建一个简单的docker映像。

我有以下Dockerfile。

FROM node:12-alpine

RUN apk add --no-cache build-base gcc autoconf automake libtool zlib-dev libpng-dev nasm

RUN mkdir -p /home/project/website/node_modules && chown -R node:node /home/project/website

WORKDIR /home/project/website

COPY /package*.json ./

USER node

RUN npm cache verify

RUN npm install

COPY --chown=node:node . .

RUN chmod +x wait-for.sh

RUN chmod -R 0755 /home/project/website/src/views/

EXPOSE 8000

当我尝试通过以下命令进行构建时 docker-compose build

我得到以下输出

Step 2/12 : RUN apk add --no-cache build-base gcc autoconf automake libtool zlib-dev libpng-dev nasm

并且我已经是第一次创建它，并且一切都运行成功，但是我更改了docker文件上的某些路径，并且删除了所有容器，图像，卷... 但是这次我遇到了这个错误。

iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
