Docker Error: EACCES: permission denied, mkdir

Question

我尝试在我的 docker 容器中为 Puppeteer 安装和创建用户。但是我得到了 ERROR 关于 mkdir 的用户权限。这是我的 Dockerfile:

FROM node:14-alpine AS builder
WORKDIR /app
COPY backend/package.json backend/package-lock.json ./
RUN npm install

COPY backend/src/ ./src
COPY backend/.env ./
COPY backend/.babelrc ./
RUN mkdir -p build/src
RUN npm run build

FROM node:alpine AS runner
WORKDIR /app

RUN apk add --no-cache \
      chromium \
      nss \
      freetype \
      harfbuzz \
      ca-certificates \
      ttf-freefont

ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true \
    PUPPETEER_EXECUTABLE_PATH=/usr/bin/chromium-browser

RUN npm install puppeteer@10.0.0

RUN addgroup -S pptruser && adduser -S -g pptruser pptruser \
    && mkdir -p /home/pptruser/Downloads /app \
    && chown -R pptruser:pptruser /home/pptruser \
    && chown -R pptruser:pptruser /app

# RUN groupadd -r pptruser && useradd -r -g pptruser  \
#     && mkdir -p /home/pptruser/Downloads /app \
#     && chown -R pptruser:pptruser /home/pptruser \
#     && chown -R pptruser:pptruser /app

USER pptruser
# USER root

COPY --from=builder /app/package.json ./
COPY --from=builder /app/package-lock.json ./
COPY --from=builder /app/.env ./
COPY --from=builder /app/build ./build
COPY --from=builder /app/node_modules ./node_modules

EXPOSE 8081

CMD ["node", "build/src/index.js"]

我使用 addgroup 和 adduser 创建了一个用户。我关注了这个文档 https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md#running-puppeteer-in-docker。我得到一个错误：

backend    | Error: EACCES: permission denied, mkdir '/app/build/src/services/csv'

backend    |   errno: -13,
backend    |   syscall: 'mkdir',
backend    |   code: 'EACCES',
backend    |   path: '/app/build/src/services/csv'
backend    | }

我的函数我得到了 Error:

const csvFolder = path.join(__dirname, "csv");
if (!fs.existsSync(csvFolder)) {
  fs.mkdirSync(csvFolder);
}

但是当我使用时：USER root。我没有收到此错误。我的目录树：

|-src
| |-services
| |-routes
| |-controllers
|-docker
| |-Dockerfile.backend

Answer 1

这是因为您使用了 2 个图像作为生成器，另一个图像用于运行ner。

因此，当您将 build 文件夹从构建器复制到运行ner 时，权限不会保留在两个容器上。

如果您使用 1 张图像作为给定的 link，它将运行成功，不会出现您上面提到的错误。

仅

FROM alpine。
