+
+## Upgrade Notices:
+
+### Docker Pi-Hole v4.2.2
+
+- ServerIP no longer a required enviroment variable **unless you run network 'host' mode**!  Feel free to remove it unless you need it to customize lighttpd
+- --cap-add NET_ADMIN no longer required unless using DHCP, leaving in examples for consistency
+
+### Docker Pi-Hole v4.1.1+
+
+Starting with the v4.1.1 release your Pi-hole container may encounter issues starting the DNS service unless ran with the following setting:
+
+- `--dns=127.0.0.1 --dns=1.1.1.1` The second server can be any DNS IP of your choosing, but the **first dns must be 127.0.0.1**
+    - A WARNING stating "Misconfigured DNS in /etc/resolv.conf" may show in docker logs without this.
+- 4.1 required --cap-add NET_ADMIN until 4.2.1-1
+
+These are the raw [docker run cli](https://docs.docker.com/engine/reference/commandline/cli/) versions of the commands.  We provide no official support for docker GUIs but the community forums may be able to help if you do not see a place for these settings.  Remember, always consult your manual too!

 ## Overview
 
 #### Renamed from `diginc/pi-hole` to `pihole/pihole`
 
 A [Docker](https://www.docker.com/what-docker) project to make a lightweight x86 and ARM container with [Pi-hole](https://pi-hole.net) functionality.
 
-1) Install docker for your [x86-64 system](https://www.docker.com/community-edition) or [ARMv7 system](https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi/) using those links.
-2) Use the appropriate tag (x86 can use default tag, ARM users need to use images from [pihole/pihole:v4.0_armhf](https://store.docker.com/community/images/pihole/pihole/tags)) in the below `docker run` command
+1) Install docker for your [x86-64 system](https://www.docker.com/community-edition) or [ARMv7 system](https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi/) using those links. [Docker-compose](https://docs.docker.com/compose/install/) is also recommended.
+2) Use the above quick start example, customize if desired.
 3) Enjoy!

 ## Running Pi-hole Docker
 
-[DockerCloud](https://store.docker.com/community/images/pihole/pihole) automatically builds the latest docker-pi-hole changes into images which can easily be pulled and ran with a simple `docker run` command.  Changes and updates under development or testing can be found in the [dev tags](#development) section.
+This container uses 2 popular ports, port 53 and port 80, so **may conflict with existing applications ports**.  If you have no other services or docker containers using port 53/80 (if you do, keep reading below for a reverse proxy example), the minimum arguments required to run this container are in the script [docker_run.sh](https://github.com/pi-hole/docker-pi-hole/blob/master/docker_run.sh)
 
-One crucial thing to know before starting is this container needs port 53 and port 80, two very popular ports that may conflict with existing applications.  If you have no other services or docker containers using port 53/80 (if you do, keep reading below for a reverse proxy example), the minimum arguments required to run this container are in the script [docker_run.sh](https://github.com/pi-hole/docker-pi-hole/blob/master/docker_run.sh) or summarized here:
+If you're using a Red Hat based distribution with an SELinux Enforcing policy add `:z` to line with volumes like so:
 
 ```
-IP_LOOKUP="$(ip route get 8.8.8.8 | awk '{ print $NF; exit }')"  # May not work for VPN / tun0
-IPv6_LOOKUP="$(ip -6 route get 2001:4860:4860::8888 | awk '{for(i=1;i<=NF;i++) if ($i=="src") print $(i+1)}')"  # May not work for VPN / tun0
-IP="${IP:-$IP_LOOKUP}"  # use $IP, if set, otherwise IP_LOOKUP
-IPv6="${IPv6:-$IPv6_LOOKUP}"  # use $IPv6, if set, otherwise IP_LOOKUP
-DOCKER_CONFIGS="$(pwd)"  # Default of directory you run this from, update to where ever.
-
-echo "### Make sure your IPs are correct, hard code ServerIP ENV VARs if necessary\nIP: ${IP}\nIPv6: ${IPv6}"
-docker run -d \
-    --name pihole \
-    -p 53:53/tcp -p 53:53/udp \
-    -p 67:67/udp \
-    -p 80:80 \
-    -p 443:443 \
-    -v "${DOCKER_CONFIGS}/pihole/:/etc/pihole/" \
-    -v "${DOCKER_CONFIGS}/dnsmasq.d/:/etc/dnsmasq.d/" \
-    -e ServerIP="${IP}" \
-    -e ServerIPv6="${IPv6}" \
-    --restart=unless-stopped \
-    --cap-add=NET_ADMIN \
-    pihole/pihole:latest
-
-echo -n "Your password for https://${IP}/admin/ is "
-docker logs pihole 2> /dev/null | grep 'password:'
+    -v "$(pwd)/etc-pihole/:/etc/pihole/:z" \
+    -v "$(pwd)/etc-dnsmasq.d/:/etc/dnsmasq.d/:z" \
 ```
 
-**This is just an example and might need changing.**  Volumes are stored in the directory `$DOCKER_CONFIGS` and are recommended for persisting data across docker re-creations for updating images.  As mentioned on line 2, the auto `IP_LOOKUP` variable may not work for VPN tunnel interfaces.
+Volumes are recommended for persisting data across container re-creations for updating images.  The IP lookup variables may not work for everyone, please review their values and hard code IP and IPv6 if necessary.
 
-Two recently added ports to the `docker run` and `docker-compose` examples are port 67 and 443.  Port 67 is for users who wish to have Pi-hole run a DHCP server.  Port 443 is to provide a sinkhole for ads that use SSL.  If only port 80 is used, then blocked HTTPS queries will fail to connect to port 443 and may cause long loading times.  Rejecting 443 on your firewall can also serve this same purpose.  Ubuntu firewall example: `sudo ufw reject https`

 **Automatic Ad List Updates** - since the 3.0+ release, `cron` is baked into the container and will grab the newest versions of your lists and flush your logs.  **Set your TZ** environment variable to make sure the midnight log rotation syncs up with your timezone's midnight.
 
+## Running DHCP from Docker Pi-Hole
+
+There are multiple different ways to run DHCP from within your Docker Pi-hole container but it is slightly more advanced and one size does not fit all. DHCP and Docker's multiple network modes are covered in detail on our docs site: [Docker DHCP and Network Modes](https://docs.pi-hole.net/docker/DHCP/)
+
 ## Environment Variables
 
 There are other environment variables if you want to customize various things inside the docker container:
 
 | Docker Environment Var. | Description |
 | ----------------------- | ----------- |
-| `-e ServerIP=<Host's IP>`<br/> **Required** | Set to your server's external IP to block ads fully
-| `-e ServerIPv6=<Host's IPv6>`<br/> *Required if using IPv6* | **If you have a v6 network** set to your server's external IPv6 to block IPv6 ads fully
-| `-e TZ=<Timezone>`<br/> **Recommended** *Default: UTC* | Set your [timezone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) to make sure logs rotate at local midnight instead of at UTC midnight.
-| `-e WEBPASSWORD=<Admin password>`<br/> **Recommended** *Default: random* | http://pi.hole/admin password. Run `docker logs pihole \| grep random` to find your random pass.

+| `DNS_FQDN_REQUIRED: <True\|False>`<br/> *Optional* *Default: true* | Never forward non-FQDNs
+| `CONDITIONAL_FORWARDING: <True\|False>`<br/> *Optional* *Default: False* | Enable DNS conditional forwarding for device name resolution
+| `CONDITIONAL_FORWARDING_IP: <Router's IP>`<br/> *Optional* | If conditional forwarding is enabled, set the IP of the local network router
+| `CONDITIONAL_FORWARDING_DOMAIN: <Network Domain>`<br/> *Optional* | If conditional forwarding is enabled, set the domain of the local network router
+| `CONDITIONAL_FORWARDING_REVERSE: <Reverse DNS>`<br/> *Optional* | If conditional forwarding is enabled, set the reverse DNS of the local network router (e.g. `0.168.192.in-addr.arpa`)
+| `ServerIP: <Host's IP>`<br/> **Recommended** | **--net=host mode requires** Set to your server's LAN IP, used by web block modes and lighttpd bind address

This guide explains how to restore webpage blocked functionality using a linux router DNAT rule: [Alternative Synology installation method](https://discourse.pi-hole.net/t/alternative-synology-installation-method/5454?u=diginc)
+| `DNSMASQ_USER: <pihole\|root>`<br/> *Experimental Default: root* | Allows running FTLDNS as non-root.
 
-Here is a rundown of the other arguments passed into the example `docker run`:
+To use these env vars in docker run format style them like: `-e DNS1=1.1.1.1`
+
+Here is a rundown of other arguments for your docker-compose / docker run.
 
 | Docker Arguments | Description |
 | ---------------- | ----------- |
-| `-p 80:80`<br/>`-p 53:53/tcp -p 53:53/udp`<br/> **Recommended** | Ports to expose, the bare minimum ports required for Pi-holes HTTP and DNS services
+| `-p <port>:<port>` **Recommended** | Ports to expose (53, 80, 67, 443), the bare minimum ports required for Pi-holes HTTP and DNS services
 | `--restart=unless-stopped`<br/> **Recommended** | Automatically (re)start your Pi-hole on boot or in the event of a crash
-| `-v /dir/for/pihole:/etc/pihole`<br/> **Recommended** | Volumes for your Pi-hole configs help persist changes across docker image updates
-| `-v /dir/for/dnsmasq.d:/etc/dnsmasq.d`<br/> **Recommended** | Volumes for your dnsmasq configs help persist changes across docker image updates
-| `--net=host`<br/> *Optional* | Alternative to `-p <port>:<port>` arguments (Cannot be used at same time as -p) if you don't run any other web application
-| `--cap-add=NET_ADMIN`<br/> *Optional* | If you're forwarding port 67 you will also needs this for DHCP to work. (DHCP Reportedly works, I have not used however)
-
-If you're a fan of [docker-compose](https://docs.docker.com/compose/install/) I have [example docker-compose.yml files](https://github.com/pi-hole/docker-pi-hole/blob/master/doco-example.yml) in github which I think are a nicer way to represent such long run commands.
+| `-v $(pwd)/etc-pihole:/etc/pihole`<br/> **Recommended** | Volumes for your Pi-hole configs help persist changes across docker image updates
+| `-v $(pwd)/etc-dnsmasq.d:/etc/dnsmasq.d`<br/> **Recommended** | Volumes for your dnsmasq configs help persist changes across docker image updates
+| `--net=host`<br/> *Optional* | Alternative to `-p <port>:<port>` arguments (Cannot be used at same time as -p) if you don't run any other web application. DHCP runs best with --net=host, otherwise your router must support dhcp-relay settings.
+| `--cap-add=NET_ADMIN`<br/> *Recommended* | Commonly added capability for DHCP, see [Note on Capabilities](#note-on-capabilities) below for other capabilities.
+| `--dns=127.0.0.1`<br/> *Recommended* | Sets your container's resolve settings to localhost so it can resolve DHCP hostnames from Pi-hole's DNSMasq, also fixes common resolution errors on container restart.

 * Port conflicts?  Stop your server's existing DNS / Web services.
-  * Ubuntu users especially may need to shut off dns on your docker server so it can run in the container on port 53
-    * 17.04 and later should disable dnsmasq.
-    * 17.10 should disable systemd-resolved service.  See this page: [How to disable systemd-resolved in Ubuntu](https://askubuntu.com/questions/907246/how-to-disable-systemd-resolved-in-ubuntu)
   * Don't forget to stop your services from auto-starting again after you reboot
+  * Ubuntu users see below for more detailed information
 * Port 80 is highly recommended because if you have another site/service using port 80 by default then the ads may not transform into blank ads correctly.  To make sure docker-pi-hole plays nicely with an existing webserver you run you'll probably need a reverse proxy webserver config if you don't have one already.  Pi-hole must be the default web app on the proxy e.g. if you go to your host by IP instead of domain then Pi-hole is served out instead of any other sites hosted by the proxy. This is the '[default_server](http://nginx.org/en/docs/http/ngx_http_core_module.html#listen)' in nginx or ['_default_' virtual host](https://httpd.apache.org/docs/2.4/vhosts/examples.html#default) in Apache and is taken advantage of so any undefined ad domain can be directed to your webserver and get a 'blocked' response instead of ads.
   * You can still map other ports to Pi-hole port 80 using docker's port forwarding like this `-p 8080:80`, but again the ads won't render properly.  Changing the inner port 80 shouldn't be required unless you run docker host networking mode.
-  * [Here is an example of running with jwilder/proxy](https://github.com/pi-hole/docker-pi-hole/blob/master/jwilder-proxy-example-doco.yml) (an nginx auto-configuring docker reverse proxy for docker) on my port 80 with Pi-hole on another port.  Pi-hole needs to be `DEFAULT_HOST` env in jwilder/proxy and you need to set the matching `VIRTUAL_HOST` for the Pi-hole's container.  Please read jwilder/proxy readme for more info if you have trouble.  I tested this basic example which is based off what I run.

+### Installing on Ubuntu
+Modern releases of Ubuntu (17.10+) include [`systemd-resolved`](http://manpages.ubuntu.com/manpages/bionic/man8/systemd-resolved.service.8.html) which is configured by default to implement a caching DNS stub resolver. This will prevent pi-hole from listening on port 53.
+The stub resolver should be disabled with: `sudo sed -r -i.orig 's/#?DNSStubListener=yes/DNSStubListener=no/g' /etc/systemd/resolved.conf`
+
+This will not change the nameserver settings, which point to the stub resolver thus preventing DNS resolution. Change the `/etc/resolv.conf` symlink to point to `/run/systemd/resolve/resolv.conf`, which is automatically updated to follow the system's [`netplan`](https://netplan.io/):
+`sudo sh -c 'rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf'`
+
+Once pi-hole is installed, you'll want to configure your clients to use it ([see here](https://discourse.pi-hole.net/t/how-do-i-configure-my-devices-to-use-pi-hole-as-their-dns-server/245)). If you used the symlink above, your docker host will either use whatever is served by DHCP, or whatever static setting you've configured. If you want to explicitly set your docker host's nameservers you can edit the netplan(s) found at `/etc/netplan`, then run `sudo netplan apply`.
+Example netplan:
+```yaml
+network:
+    ethernets:
+        ens160:
+            dhcp4: true
+            dhcp4-overrides:
+                use-dns: false
+            nameservers:
+                addresses: [127.0.0.1]
+    version: 2
+```
+
+Note that it is also possible to disable `systemd-resolved` entirely. However, this can cause problems with name resolution in vpns ([see bug report](https://bugs.launchpad.net/network-manager/+bug/1624317)). It also disables the functionality of netplan since systemd-resolved is used as the default renderer ([see `man netplan`](http://manpages.ubuntu.com/manpages/bionic/man5/netplan.5.html#description)). If you choose to disable the service, you will need to manually set the nameservers, for example by creating a new `/etc/resolv.conf`.
+
+Users of older Ubuntu releases (circa 17.04) will need to disable dnsmasq.

 ## Upgrading, Persistence, and Customizations
 
 The standard Pi-hole customization abilities apply to this docker, but with docker twists such as using docker volume mounts to map host stored file configurations over the container defaults.  Volumes are also important to persist the configuration in case you have removed the Pi-hole container which is a typical docker upgrade pattern.
 
-### Upgrading
+### Upgrading / Reconfiguring
 
-`pihole -up` is disabled.  Upgrade the docker way instead, please.  Long-living docker containers are not the docker way since they aim to be portable and reproducible, why not re-create them often!  Just to prove you can.
+Do not attempt to upgrade (`pihole -up`) or reconfigure (`pihole -r`).  New images will be released for upgrades, upgrading by replacing your old container with a fresh upgraded image is the 'docker way'.  Long-living docker containers are not the docker way since they aim to be portable and reproducible, why not re-create them often!  Just to prove you can.

 1. Download the latest version of the image: `docker pull pihole/pihole`
 2. Throw away your container: `docker rm -f pihole`
-  * **Warning** When removing your pihole container you may be stuck without DNS until step 3; **docker pull** before **docker rm -f** to avoid DNS inturruption **OR** always have a fallback DNS server configured in DHCP to avoid this problem altogether.
-  * If you care about your data (logs/customizations), make sure you have it volume-mapped or it will be deleted in this step.

 3. Start your container with the newer base image: `docker run <args> pihole/pihole` (`<args>` being your preferred run volumes and env vars)
 
-Why is this style of upgrading good?  A couple reasons: Everyone is starting from the same base image which has been tested to know it works.  No worrying about upgrading from A to B, B to C, or A to C is required when rolling out updates, it reducing complexity, and simply allows a 'fresh start' every time while preserving customizations with volumes.  Basically I'm encouraging [phoenix servers](https://www.google.com/?q=phoenix+servers) principles for your containers.

-## Development
+## Note on Capabilities
 
-Development image tags coming soon
+DNSMasq / [FTLDNS](https://docs.pi-hole.net/ftldns/in-depth/#linux-capabilities) expects to have the following capabilities available:
+- `CAP_NET_BIND_SERVICE`: Allows FTLDNS binding to TCP/UDP sockets below 1024 (specifically DNS service on port 53)
+- `CAP_NET_RAW`: use raw and packet sockets (needed for handling DHCPv6 requests, and verifying that an IP is not in use before leasing it)
+- `CAP_NET_ADMIN`: modify routing tables and other network-related operations (in particular inserting an entry in the neighbor table to answer DHCP requests using unicast packets)
+
+This image automatically grants those capabilities, if available, to the FTLDNS process, even when run as non-root.\
+By default, docker does not include the `NET_ADMIN` capability for non-privileged containers, and it is recommended to explicitly add it to the container using `--cap-add=NET_ADMIN`.\
+However, if DHCP and IPv6 Router Advertisements are not in use, it should be safe to skip it. For the most paranoid, it should even be possible to explicitly drop the `NET_RAW` capability to prevent FTLDNS from automatically gaining it.
