在容器构建过程中如何将主机OS文件映射到容器 [英] How to map the host OS file to the container at the time of container build process

问题描述

docker-compose.yml：

docker-compose.yml:

    version: '3'
    services:
      ezmove:
        volumes:
          - /host-dir:/home/container-dir    
        build:
          context: .
          args:
            BRANCH: develop

Dockerfile：

Dockerfile:

FROM appcontainers/ubuntu:xenial

MAINTAINER user <user>

RUN apt-get update -y --no-install-recommends \
    && apt-get install -y --no-install-recommends python3.5-minimal python3.5-venv \    
    && apt-get install -y --no-install-recommends git \
    && apt-get install -y --no-install-recommends python-pip \
    && pip install --upgrade pip \  
    && rm -rf /var/lib/apt/lists/* \
    && mkdir -p /home/container-dir 

WORKDIR /home/container-dir 

RUN /bin/bash - c "sh ./script.sh"

在构建时间，docker容器如何将本地目录映射到容器

At the time of build the docker container How to map local directory to container

当$ docker-compose up时，它将开始构建容器，但是在安装packag依赖项后，它将尝试执行script.sh文件，但出现错误文件未找到！

When $ docker-compose up, it will starts to build container but after installation of the packag dependancies it will try to execute the script.sh file but got error "FILE NOT FOUND! "

尝试过：

1. 不想要待办事项docker clone内的git clone


2. 不想将源代码存储在Continer内

因此，如何在构建时将主机OS文件映射到容器

推荐答案

您缺少一些 COPY 或 ADD 在Dockerfile中，以便在图像中复制script.sh。

you lack some COPY or ADD in your Dockerfile in order to copy your script.sh in your image.

检查文档

顺便说一句，Docker是关于隔离的，因此应该将运行中的容器与主机隔离，并且一定不能访问主机操作系统。

By the way, Docker is about isolation, so a running container should be isolated from the host, and certainly not access the host OS.
