[SUPPORT] pihole for unRaid - Spants repo


Recommended Posts

For anybody else that has the problem as me, I was able to solve it by creating a file, dnsmasq.d/10-custom.conf, that contained

addn-hosts=/etc/pihole/extrahosts.list

then I created the extrahosts.list file in the pihole directory with the hosts entries I wanted for my local network.

Still no support for IPv6?

 

Using the documentation here https://github.com/diginc/docker-pi-hole I managed to 50% get Ipv6 to work.  I say 50% because so far it is only been tested and working on a Windows 10 PC.  I assume Linux will work as well since you can configure DNS entries for it.

 

Steps:

1. Make sure your unRAID servers network settings have IPv4 + IPv6 set

2. Add a new variable to the piHole docker configuration

image.png.6a35c6fa51fb3473ddd8056900b30fc3.png

 

I got the IPv6 from my router and just copy pasted it into the Value field.

3. Save the new field

4. Click apply and let the container rebuild

5. Edit your network connection in your PC as follows for "Internet Protocol Version 6"

Unfortunately I can't get my router to use this new IPv6 address as its default IPv6 DNS and only clients with configurable DNS entries seem to work right now.

Exactly what I needed but seems I need to get IPv6 configured on unRAID in order for this to work. I tried just ticking the boxes to turn on IPv6 in both Network Settings and Docker settings but my containers will pull down an IPv6 IP but can't seem to make an outgoing connections. Hopefully someone can point me in the right direction to get IPv6 setup properly. It works on the rest of the machines on my network, just not the docker containers.

You need to have an IPv6 subnet and gateway defined on the interface which is used by the docker containers.

In my case I use a dedicated interface eth1 (br1) for container communications. Under network settings this interface is configured as IPv4+IPv6 without IP addresses assigned.

Next in my docker settings the IPv4 and IPv6 assignments are set manually:

image.thumb.png.021dcdbe9ec85411178f03b690579911.png

 

If you use another interface or VLAN interface for docker containers, it should have similar settings manually set by you.

Docker does not allow communication between containers and host address (normal setup for eth0/br0), you should use a VLAN interface or dedicated interface to make this work.

 

I let the pihole container start as the very first container. Hence it will always get the next available IPv6 address in this range ::2. This address is configured as variable for pihole.

Make sure your router has gateway address ::1 assigned. I am using a Ubiquiti USG router, see example below.

This is how pi-hole network settings look like

And you need to select IPv6 DNS servers, e.g. google

The problem is that this docker just randomly stops working. (closes itself)

 

Maybe you cann tell me how to reach the error log inside the container, bc its not linked to the outside, which would be a good idea btw.

Also having problems after the last update, with pihole docker quitting shortly after startup.

 

ETA:  During the brief period it is up, I have thrown several dig queries at it ('dig google.com @pihole') and the resolve just fine, so I am not sure what the "DNS resolution is currently unavailable" error means.

 

I have manually downgraded to the debian_v3.3 tag and I no longer have sudden crashes.  I don't know what the problem is with later versions, but I have had the same problem (crashing after only a couple of minutes) with v3.3.1, v3.3.1-1, and prerelease,

how?

 

Was that question to me?

 

You can change the target version in the "Edit" page (where you set up all your parameters).  The default container is "diginc/pi-hole:latest" (I think—I am not looking at the unraid screen right now—but the ':latest' part is the tag we want to change).  To find the available tags, you go to the docker bug page for the container.  That's in an earlier post in this thread, and can be found off the Community Applications listing for any given container.  In this case, it is https://hub.docker.com/r/diginc/pi-hole/.

 

So, go to that page and click the "Tags" nav link at the top.  Based on the change dates, I figured out that ':latest' must refer to ':debian_v3.3.1' (or newer) and that the version I was running prior to the last update had to be ':debian_v3.3'.

 

Last step is to edit the container, change the ':latest' tag to the ':debian_v3.3' tag and click Apply.  The container will reinstall based on the older version.

 

I guess I will follow newer releases and try them every once in while to see if the problem is solved.  In the meantime, v3.3 seems to work well enough for me.

Y, thanks.

 

That ":debian_v3.3" would have done it for me, but im sure maybe some other can use ur detailed explanation :P

 

Since u used this version , it didnt crashed? Ill try it.

What kind of problems?

 

I am using pihole without any problems on both ipv4 and ipv6 connections.

 

 

Can't start the docker anymore, Execution error Bad parameter. Re installed and works now. Only set manual update for this docker.

Hi,

 

First of all I just want to thank everyone involved with Pi-Hole, it's an awesome software? 

 

I just noticed that my Pi-Hole container crashes and won't start.

I haven't done any changes that I can think of that would course this.

 

This is the log from the container:

Thank you! 

 

This is the problem:

/etc/pihole/setupVars.conf: line 4: 9.9.9.9: command not found

What is in your setupVars.conf file?

Ah, didn't check that. Thank you!

 

The files looked like this:

IPV4_ADDRESS=192.168.1.2
IPV6_ADDRESS=
WEBPASSWORD=998ed4d621742d0c2d85ed84173db569afa194d4597686cae947324aa58ab4bb
PIHOLE_DNS_1= 9.9.9.9
PIHOLE_DNS_2=8.8.8.8
PIHOLE_INTERFACE=br0

The problem was that (somehow) a space got in front of the value behind "PIHOLE_DNS_1".

I remove the space in the XML/container config and now it works again.

@TexasAg - if you do that, then does the query log show the host instead of the IP under "Client"? 

Or is that just to make local DNS queries resolve?
