当docker-compose的一部分时,自定义nginx容器立即退出
我正在尝试学习如何将docker
compose与nginx容器的简单设置结合使用,该设置将请求重新路由到ghost容器。我正在使用标准的鬼影图像,但是有一个自定义的nginx图像(继承自标准图像)。
当我使用“ docker-compose up”运行合成文件时,它会立即退出,而“
docker_nginx_1以代码0退出”。但是,当我手动构建并运行它时,它运行良好,并且可以将浏览器导航到该容器并查看默认的nginx页面。我对撰写文件的误解是什么导致其行为与自定义构建有所不同?我该如何更改才能使其继续运行?
免责声明:我同时也在学习nginx,因此一次学习两件事可能会给我带来不必要的问题。
编辑:原始文件要复杂一些,但我已将问题简化为:如果我对自定义映像使用build命令,该自定义映像除了从默认的nginx映像继承外什么也不做,因此会立即退出。如果我使用默认的nginx图像,它将起作用。这些是现在相关的文件:
撰写文件:
ghost: expose:
- "2368"
image: ghost
nginx:
# image: nginx << If I use this instead of my custom build, it doesn't exit
build: ./nginx
ports:
- "80:80"
- "443:443"
links:
- ghost
nginx / Dockerfile:
FROM nginx
原始文件(具有与上述相同的撰写文件):
nginx / Dockerfile:

EXPOSE 80 443

CMD service nginx start

}

回答:
刚遇到同样的问题,最初的 解决方法 是更改中的服务名称docker-compose.yml
。
这行得通,但 行得通,是因为Docker-compose缓存了构建并将其与服务名称绑定。每个docker-compose
up后的第一个只使用它之前建造的,所以所做的任何更改的Dockerfile
,或者的那部分docker-compose.yml
基本上忽略。
当您(和我)更改服务名称时,由于该服务名称之前没有被标记过,因此它触发了新的构建。
的 的解决方案是做一个:搬运工-
撰写生成重建图像(后面跟一个docker-
compose up)。他们的文档并没有真正强调这个问题。
