Issue
I'm a newbie at docker. I'm creating a Hello, World example. All I'm trying to do is bring up Apache in a docker and then view the default website from the host machine.
Dockerfile
FROM centos:latest
RUN yum install epel-release -y
RUN yum install wget -y
RUN yum install httpd -y
EXPOSE 80
ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]
And then I build it:
> docker build .
And then I tag it:
docker tag 17283f566320 my:apache
And then I run it:
> docker run -p 80:9191 my:apache
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message
It then runs....
In another terminal window, I attempt to issue the curl command to view the default web site.
> curl -XGET http://0.0.0.0:9191
curl: (7) Failed to connect to 0.0.0.0 port 9191: Connection refused
> curl -XGET http://localhost:9191
curl: (7) Failed to connect to localhost port 9191: Connection refused
> curl -XGET http://127.0.0.1:9191
curl: (7) Failed to connect to 127.0.0.1 port 9191: Connection refused
or I try localhost
Just to make sure that I got the port correct, I run this:
> docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5aed4063b1f6 my:apachep "/usr/sbin/httpd -D F" 43 seconds ago Up 42 seconds 80/tcp, 0.0.0.0:80->9191/tcp angry_hodgkin
Solution
Thanks to all. My ports were reversed:
> docker run -p 9191:80 my:apache
