Can't reach Wordpress on Raspberry Pi 3 despite correct setup

General

Hey guys,

So I got my Raspberry Pi 3 yesterday and set out to setup my wordpress instance. I’m using the following images:
https://hub.docker.com/r/hypriot/rpi-mysql/ - For my database
https://hub.docker.com/r/arm32v6/wordpress/ - For wordpress (also tried v7)

The commands I use to set them up are the following:
docker run --name mysql -e MYSQL_ROOT_PASSWORD=**** -d hypriot/rpi-mysql
docker run --name wordpress --link mysql:mysql -p 8080:80 --restart always -it -d arm32v6/wordpress

Both of them show up correctly when I do a ‘docker ps’ . But for some reason whenever I go to localhost:8080 it says that it is unreachable. (I’m logged into the Raspberry through VNC and using the chromium browser there).

I reinstalled basically everything including docker itself several times, but nothing seems to be working.

docker inspect the wordpress container… to look at the port mappings

3

unreachable makes it sound like the browser doesn’t know where localhost is…

cat /etc/hosts

also try 127.0.0.1:8080

I’m guessing you meant this? There is quite a lot of output there, so let me know if this wasn’t what you were asking for

Also here is the content of the hosts file:
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

127.0.1.1 raspberrypi

Trying 127.0.0.1:8080 didn’t do anything, I get the same response

“Ports”: {
“80/tcp”: [
{
“HostIp”: “0.0.0.0”,
“HostPort”: “8080”
}
],
“9000/tcp”: null
},

that looks good…

assuming vnc is causing some problem… if u do http://172.17.0.3:8080 from the container… it should work…

I’m not quite sure what you mean by from the container. How can I run chromium from within the container?

7

sorry, brain fart… trying to make sure the address resolution is happening on the pi… not the system u are vncing from.

8

Well, I can physically connect my pc to the router that the pi is connected to through Wifi, but I get the same error there too when I try to use my browser.

9

and when connected that way, you are doing http://pi_address:8080, right?

10

Yeah, more specifically 192.168.10.101:8080

11

The thing is that if I try another web-based container, for example this: https://hub.docker.com/r/hypriot/rpi-dockerui/
I can access it without a problem. So it isn’t my network, but something with wordpress maybe?

12

maybe the wordpress app didn’t start for some reason

docker log container_id

might give u info

Not really, all I got was this:
[16-Dec-2017 18:41:27] NOTICE: fpm is running, pid 1
[16-Dec-2017 18:41:27] NOTICE: ready to handle connections

never a dull moment!
