Apache docker 容器未开始使用 docker-compose up

Question

我正在研究一个用例，为 CMS 应用程序的 apache 服务器创建 Docker 容器。

以下是摘要容器的文件夹结构。

apache-rproxy-docker (folder)
  -docker-compose.yml
  - httpd (folder)
     - Dockerfile
     - httpd.conf

docker-compose.yml

version: '2.1'

services:
  apache:
    build: httpd/
    ports:
      - "80:80"
    networks:
      - my_network
    restart: always

networks:
  my_network:
    driver: bridge

Docker文件

FROM httpd:2.4
COPY ./httpd.conf /usr/local/apache2/conf/httpd.conf

httpd.conf

Listen 80

ServerName localhost:80
ServerAdmin admin@localhost

ErrorLog logs/error.log

# Note that the following LoadModule lines only represent the minimum 'Web-Developer' Suite configuration.
#
# Also note that some of the following LoadModule lines, which are commented out, are still loaded under…
# confSuite-extra*.conf
# confextra*.conf
# …configuration files -- for modular reasons.
# 
# For example:
# mod_deflate is loaded under confSuite-extramod_deflate_logio.conf and NOT under httpd.conf
# status_module is loaded under confextrahttpd-info.conf and NOT under httpd.conf
#
# Check last part of httpd.conf for the Apache base and 'Web-Developer' *.conf files that are included.

我有几个问题阻碍了我，

虽然我能够毫无问题地构建容器，但是当尝试使用“docker-compose up”启动容器时，容器启动并立即终止，没有任何错误。
我没有看到容器的端口映射，这很奇怪。

下面是执行 docker inspect container_id.

时的输出

我是第一次在 docker 上工作。非常感谢任何帮助。

谢谢！

Answer 1

好的，我能够使用您提供的文件重现您的问题。奇怪的是您没有在日志中获得更多信息。但这是我调试它的方式：

状态为 restarting 的事实很糟糕 - 这意味着您的容器无法正常工作。我删除了 restart: always 行，但得到了相同的结果。
让我们进一步缩小问题范围。我在 httpd 目录中通过运行以下命令构建了你的 Dockerfile 和运行它：docker build -t apache-rproxy:latest . && docker run --rm -p 80:80 apache-rproxy:latest。不幸的是，我得到了同样的错误，没有额外的日志。
让我们再调试一下。使用官方 httpd 映像尝试相同的命令：docker run --rm -p 80:80 httpd:2.4。请注意，这次 httpd 启动并开始记录日志，并且容器保持活动状态。

现在，httpd:2.4 图像和 apache-rproxy:latest 图像之间的唯一区别是您的配置文件。因此，您 httpd.conf 中的某些内容阻止了 apache 启动（甚至无法记录任何内容）。找出问题所在，我想你会有一个有效的设置。
