## [Alpine-PDNSd][234]
#### Container for Alpine Linux + Proxy DNS Daemon (caching recursive DNS Server)
---

This [image][233] containerizes the [PDNSd][135] DNS server with
persistent caching-to-disk and recursion/forwarding, mainly used
to resolve domain names (both local devices and outsiders) and
blocking ads inside the local network.

Based on [Alpine Linux][131] from my [alpine-s6][132] image with
the [s6][133] init system [overlayed][134] in it.

The image is tagged respectively for the following architectures,
* **armhf**
* **x86_64** (retagged as the `latest` )

**armhf** builds have embedded binfmt_misc support and contain the
[qemu-user-static][105] binary that allows for running it also inside
an x64 environment that has it.

---
#### Get the Image
---

Pull the image for your architecture it's already available from
Docker Hub.

```
# make pull
docker pull woahbase/alpine-pdnsd:x86_64
```

---
#### Run
---

Before you run..

* Default configuration is at `/etc/pdnsd.conf`, the default is
provided in `root/defaults`, put your custom config file at
`/data/pdnsd.conf` at it will be copied over at start.

* Local names are served from `/data/hosts/hosts.local`, if not
found, `/etc/hosts` is copied.

* A default blocklist from the following sources are provided as
default at `/etc/hosts.blocked`. On start, this is copied over
to `/data/hosts/hosts.blocked`, if not existing already. Replace
this file to use your own blocking list. Current build
combines the following lists ..

* [AdAway's Sources](https://github.com/AdAway/AdAway/wiki/hostssources)
* [Someonewhocares](http://someonewhocares.org/hosts/zero/hosts)
* [StevenBlack's List](https://github.com/StevenBlack/hosts)
* [hpHosts](https://hosts-file.net/)

* To unblock a specific domain from the blocklist, put it inside
`/data/hosts/hosts.whitelisted` ( Needs restart ).
To manually unblock using `sed`..

```
sed -i \
-e 's/\([ . ]\)rt.com/\1notrt.com/g' \
/data/hosts/*
```

* On many systemd derivations e.g. ArchLinux, 53/udp may be
already taken by systemd-resolved. In that case, it will need to
be stopped first before dns server is started. Run,

```
sudo systemctl stop systed-resolved
```

If you want to run images for other architectures, you will need
to have binfmt support configured for your machine. [**multiarch**][104],
has made it easy for us containing that into a docker container.

```
# make regbinfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset
```

Without the above, you can still run the image that is made for your
architecture, e.g for an x86_64 machine..

Running `make` starts the service.

```
# make
docker run --rm -it \
--name docker_pdnsd --hostname pdnsd \
-e PGID=1000 -e PUID=1000 \
-c 256 -m 400m -p 53:53/tcp -p 53:53/udp \
-v data:/data \
-v /etc/hosts:/etc/hosts:ro \
-v /etc/localtime:/etc/localtime:ro \
woahbase/alpine-pdnsd:x86_64
```

Stop the container with a timeout, (defaults to 2 seconds)

```
# make stop
docker stop -t 2 docker_pdnsd
```

Removes the container, (always better to stop it first and `-f`
only when needed most)

```
# make rm
docker rm -f docker_pdnsd
```

Restart the container with

```
# make restart
docker restart docker_pdnsd
```

---
#### Shell access
---

Get a shell inside a already running container,

```
# make shell
docker exec -it docker_pdnsd /bin/bash
```

set user or login as root,

```
# make rshell
docker exec -u root -it docker_pdnsd /bin/bash
```

To check logs of a running container in real time

```
# make logs
docker logs -f docker_pdnsd
```

---
### Development
---

If you have the repository access, you can clone and
build the image yourself for your own system, and can push after.

---
#### Setup
---

Before you clone the [repo][231], you must have [Git][101], [GNU make][102],
and [Docker][103] setup on the machine.

```
git clone https://github.com/woahbase/alpine-pdnsd
cd alpine-pdnsd
```
You can always skip installing **make** but you will have to
type the whole docker commands then instead of using the sweet
make targets.

---
#### Build
---

You need to have binfmt_misc configured in your system to be able
to build images for other architectures.

Otherwise to locally build the image for your system.
[`ARCH` defaults to `x86_64`, need to be explicit when building
for other architectures.]

```
# make ARCH=x86_64 build
# sets up binfmt if not x86_64
docker build --rm --compress --force-rm \
--no-cache=true --pull \
-f ./Dockerfile_x86_64 \
--build-arg ARCH=x86_64 \
--build-arg DOCKERSRC=alpine-s6 \
--build-arg PGID=1000 \
--build-arg PUID=1000 \
--build-arg USERNAME=woahbase \
-t woahbase/alpine-pdnsd:x86_64 \
.
```

To check if its working..

```
# make ARCH=x86_64 test
docker run --rm -it \
--name docker_pdnsd --hostname pdnsd \
-e PGID=1000 -e PUID=1000 \
--entrypoint pdnsd
woahbase/alpine-pdnsd:x86_64 \
'--version'
```

And finally, if you have push access,

```
# make ARCH=x86_64 push
docker push woahbase/alpine-pdnsd:x86_64
```
