docker和docker-compose节点api：npm ERR！代码EACCES [英] docker and docker-compose node api: npm ERR! code EACCES

问题描述

HELLO我具有以下文件夹结构

HELLO I have the following folders structure

main

|- .docker-compose.yml
|- backend/
   |- micro-hr/
      |-.dockerfile
   |- rabbitmq

我的码头工人组成：

 micro-hr:
   build: 
     context: .
     dockerfile: backend/micro-hr/Dockerfile
  entrypoint: /usr/src/api/.docker/entrypoint.sh
  container_name: micro-hr
  environment:
    - CHOKIDAR_USEPOLLING=true
  ports:
  - 3001:3000

我的dockerfile：

my dockerfile:

FROM node:lts-alpine
#create app directory
#xx
RUN mkdir /usr/src
RUN apk add --no-cache bash git
RUN touch /usr/src/.bashrc | echo "PS1='\w\$ '" >> /usr/src/.bashrc
#copy files
COPY backend/micro-hr/ormconfig.ts backend/micro-hr/.env backend/micro-hr/package.json backend/micro-hr/yarn.* /usr/src/api/
COPY backend/rabbitmq/package.json /usr/src/rabbitmq/
#install modules lib modules
RUN cd /usr/src/api/ && npm install
#copy other files
COPY backend/micro-hr/ /usr/src/api/
COPY backend/rabbitmq /usr/src/rabbitmq

RUN chown -R node:node /usr/src/api
RUN chown -R node:node /usr/src/rabbitmq
WORKDIR /usr/src/api

#set work dir
USER node

我的入口点.sh：

#!/bin/bash

npm config set cache /usr/src/api/.npm-cache --global

cd /usr/src/api

npm install
npm run start:dev

我在docker-compose up --build：

i got this error on docker-compose up --build:

micro-hr              | > micro-hr@1.0.0 postinstall /usr/src/api
micro-hr              | > npm link ../rabbitmq/

micro-hr              | npm ERR!   code: 'EACCES',

micro-hr              | npm ERR!   dest: '/usr/local/lib/node_modules/rabbitmq'
micro-hr              | npm ERR! }

和：

micro-hr | npm WARN checkPermissions缺少对/ usr / src / api / node_modules / has-symbols micro-hr的写访问
| npm
WARN checkPermissions缺少对
的写访问权/usr/src/api/node_modules/highlight.js

micro-hr | npm WARN checkPermissions Missing write access to /usr/src/api/node_modules/has-symbols micro-hr | npm WARN checkPermissions Missing write access to /usr/src/api/node_modules/highlight.js

我知道这是一个权限问题，但我不知道如何解决。
的问题是在安装我的npm链接模块时：

I know it's a problem with permission but I can't figure out how to fix it. the problem is when installing my npm link modules:

"postinstall": "npm link ../rabbitmq/",
"postupdate": "npm link ../rabbitmq/",

推荐答案

我认为问题是作为root用户运行 npm install 。

I think the problem is running npm install as root.

尝试

USER node
RUN cd /usr/src/api/ && npm install
#copy other files
COPY --chown node:node backend/micro-hr/ /usr/src/api/
COPY --chown node:node backend/rabbitmq /usr/src/rabbitmq
WORKDIR /usr/src/api

而不是

RUN cd /usr/src/api/ && npm install
#copy other files
COPY backend/micro-hr/ /usr/src/api/
COPY backend/rabbitmq /usr/src/rabbitmq

RUN chown -R node:node /usr/src/api
RUN chown -R node:node /usr/src/rabbitmq
WORKDIR /usr/src/api

#set work dir
USER node

基于这篇文章我会将之前的建议修改为：

Based on this article I would modify my previous suggestion to:

USER node
RUN mkdir ~/.npm-global && npm config set prefix '~/.npm-global' && \
    export PATH=~/.npm-global/bin:$PATH && \
    cd /usr/src/api/ && npm install
#copy other files
ENV PATH="~/.npm-global/bin:${PATH}"
COPY --chown node:node backend/micro-hr/ /usr/src/api/
COPY --chown node:node backend/rabbitmq /usr/src/rabbitmq
WORKDIR /usr/src/api

编辑：

我认为 entrypoint.sh 可能会导致新问题：

I think this line in entrypoint.sh may cause the new problem:

npm config set cache /usr/src/api/.npm-cache --global

尝试将其删除或注释并重建图像。

Try removing or commenting it out and rebuilding the image.
