Question

我是 Docker 的新手，并试图通过它的 documentation 来学习它。因为我需要使用 docker 镜像为 nginx 服务器创建 NextJS 构建，所以我遵循了以下过程。

安装 nginx
Seeding the port 80 to 3000 in the default config。
将 out 目录符号链接到基础 nginx 目录
CMD 负责输出目录的生产构建和符号链接。

FROM node:alpine AS deps

RUN apk add --no-cache libc6-compat git
RUN apt-get install nginx -y

WORKDIR /sample-app
COPY package.json yarn.lock ./
RUN yarn install --frozen-lockfile

FROM node:alpine AS builder
WORKDIR /sample-app
COPY . .
COPY --from=deps /sample-app/node_modules ./node_modules
RUN yarn build

FROM node:alpine AS runner
WORKDIR /sample-app

ENV NODE_ENV production

RUN ls -SF /sample-app/out /usr/share/nginx/html
RUN -p 3000:80 -v /sample-app/out:/usr/share/nginx/html:ro -d nginx
RUN addgroup -g 1001 -S nodejs
RUN adduser -S nextjs -u 1001
RUN chown -R nextjs:nodejs /sample-app/out
USER nextjs

CMD ["nginx -g daemon=off"]

在以 sudo docker build . -t sample-app 运行 docker build shell 脚本命令时，它抛出错误 The command '/bin/sh -c apt-get install nginx -y' returned a non-zero code: 127

Answer 1

我对 alpine 镜像没有太多经验，但我认为您必须使用 apk（Alpine Package Keeper）来安装软件包

尝试apk add nginx而不是apt-get install nginx -y

使用 nginx 服务器构建 NextJS Docker 镜像
