Question

我有以下Dockerfile_dev泊坞文件：

FROM node:alpine
MAINTAINER "Desyllas Dimitrios"

ENV NEO4J_HOST=""
ENV NEO4J_USER=""
ENV NEO4J_PASSWORD=""
ENV MONGO_CONNECTION_STRING=""
ENV LOGS_DIR="/var/log/data_map"

COPY ./docker_scripts/entrypoint_dev.sh /usr/local/bin/entrypoint.sh

RUN chmod +x /usr/local/bin/entrypoint.sh &&\
    chown root:root /usr/local/bin/entrypoint.sh &&\
    mkdir -p /opt/map &&\
    mkdir -p /var/log/data_map &&\
    chmod 0666 /var/log/data_map

EXPOSE 7474
VOLUME /var/log/data_map
VOLUME /opt/map

WORKDIR /opt/map

ENTRYPOINT ['/usr/local/bin/entrypoint.sh']

我有以下入口点：

#!/bin/sh

cd /opt/map

npm install
npm start

构建图像通过以下docker-compose

启动

version: '2'
services:

  data_map_dev:
    build:
      context: .
      dockerfile: Dockerfile_dev
    image: 'pcmagas/data-map:dev'
    links:
      - 'neo4j_dev'
      - 'mongodb'
    volumes:
      - './src:/opt/map/src'
      - './www:/opt/map/www'
      - './package.json:/opt/map/package.json'
      - './docker-volumes/app_dev:/var/log/datamap'
    ports:
      - "9781:9780"
    environment:
      NEO4J_HOST: 'neo4j_dev'
      NEO4J_USER: 'neo4j'
      NEO4J_PASSWORD: 'neo4j'
      MONGO_CONNECTION_STRING: 'mongodb://mongodb:map_dev'

  neo4j_dev:
    image: 'neo4j'
    ports:
      - '7474:7474'
    volumes:
      - './docker-volumes/neo4j_dev/data:/data'
    environment:
      NEO4J_AUTH: 'neo4j/neo45j'

  mongodb:
    image: 'mongo'
    ports:
      - '27017:27017'
    volumes:
      - './docker-volumes/mongodb/:/data/db'

我使用docker-compose build --no-cache --force-rm构建它，当我通过docker-compose up启动它时，它无法找到您在消息上看到的入口点脚本：

data_map_dev_1 | / bin / sh：[/usr/local/bin/entrypoint.sh]：找不到

你知道为什么吗？我在my project也有类似的问题。

Answer 1

您的JSON语法错误。

注意：exec表单被解析为JSON数组，这意味着您必须使用双引号（“）来围绕单词而不是单引号（'）。

https://docs.docker.com/engine/reference/builder/

切换到双引号，如下所示：

ENTRYPOINT ["/usr/local/bin/entrypoint.sh"]

Docker节点：找不到入口点
