Question

尝试在个人Mac和Docker digitalocean Droplet上启动openresty docker（https://github.com/3scale/docker-openresty），但收到错误：

DEBG 'openresty' stderr output:
nginx: [emerg] bind() to 0.0.0.0:8080 failed (98: Address already in use)

CONFIGS：

1）Dockerfile

FROM 3scale/openresty
ADD openresty.conf /etc/supervisor/conf.d/
ADD . /var/www
CMD ["supervisord"]

2）Openresty.conf

[program:openresty]
command=/opt/openresty/nginx/sbin/nginx -p /var/www/ -c config/nginx.conf
autorestart=true

3）config / nginx.conf

worker_processes  1;
error_log logs/error.log;
events {
    worker_connections 1024;
}
http {
server {
    listen 8080;
    location / {
        default_type text/html;
        content_by_lua '
            ngx.say("<p>hello, world</p>")
        ';
    }
}
}

我是如何推出的：

docker build -t resty_docker .
docker run resty_docker

结果：

Answer 1

好的，问题不在于ONBUILD CMD ["supervisord", "-n"]，而是在nginx背景和主管杀死它。

将daemon off;添加到nginx.conf后，问题就消失了。

Answer 2

您的父容器3scale/openresty具有行ONBUILD CMD ["supervisord", "-n"]这意味着sypervisord已在运行（有关ONBUILD的详细信息，请参阅here）。当你的supervisord命令运行时，它会发现冲突。

无法启动openresty docker
