apache - Docker:镜像构建失败

Question

当构建docker apache镜像时，构建在此步骤中失败:

Step n/m : COPY httpd-foreground /usr/local/bin/

ERROR: Service 'apache' failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder511740141/httpd-foreground: no such file or directory

这是我的docker_compose.yml文件

version: '3'

services:
  mysql:
    image: mysql:5.7
    container_name: mysql_octopus_dev
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: app
      MYSQL_USER: root
      MYSQL_PASSWORD: root
  apache:
    build: .
    container_name: apache_octopus_dev
    volumes:
      - .:/var/www/html/
    ports:
      - "8000:80"
    depends_on:
      - mysql

这是我的 docker 文件

FROM debian:jessie-backports

# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added
#RUN groupadd -r www-data && useradd -r --create-home -g www-data www-data
...

COPY httpd-foreground /usr/local/bin/

EXPOSE 80
CMD ["httpd-foreground"]

有什么帮助吗？

Answer 1

Dockerfile中的路径始终相对于上下文目录。上下文目录是传递给docker build的位置参数(通常为)。

我应该将httpd-foreground文件放置在dockerfile的同一文件夹中。
