 # Remote-Wake-Sleep-On-LAN-Docker
-A docker image of sciguy14/Remote-Wake-Sleep-On-LAN-Server
+A docker image of [sciguy14/Remote-Wake-Sleep-On-LAN-Server](https://github.com/sciguy14/Remote-Wake-Sleep-On-LAN-Server)
+
+## Summary
+
+> The Remote Wake/Sleep-on-LAN Server (RWSOLS) is a simple webapp that runs on Docker to remotely power up any computer via WOL. </br> This is necesarry, since WOL packages (Layer&nbsp;2) cannot be forwarded via a normal VPN (Layer&nbsp;3).
+
+![preview img](IMG_webinterface_preview.png)
+
+**Information:**
+- You don't need any additinal software to wake your client via WOL.
+- Additional software is needed to sleep/shutdown your client via this webinterface.
+
+## Usage
+Here are some example snippets to help you get started creating a container.
+
+### docker-compose (recommended)
+```
+version: "3"
+
+services:
+  frontend-rwsols:
+    image: ex0nuss/XXX
+    container_name: frontend-rwsols
+    restart: unless-stopped
+    network_mode: host
+    environment:
+      - APACHE2_PORT=8080
+      - PASSPHRASE=MyPassword
+      - RWSOLS_COMPUTER_NAME="Pc1","Pc2"
+      - RWSOLS_COMPUTER_MAC="XX:XX:XX:XX:XX:XX","XX:XX:XX:XX:XX:XX"
+      - RWSOLS_COMPUTER_IP="192.168.1.45","192.168.1.50"
+```
+
+### docker CLI
+``` 
+docker run -d \
+  --name=frontend-rwsols \
+  --network="host" \
+  -e APACHE2_PORT=8080 \
+  -e PASSPHRASE=MyPassword \
+  -e RWSOLS_COMPUTER_NAME="Pc1","Pc2" \
+  -e RWSOLS_COMPUTER_MAC="XX:XX:XX:XX:XX:XX","XX:XX:XX:XX:XX:XX" \
+  -e RWSOLS_COMPUTER_IP="192.168.1.45","192.168.1.50" \
+  --restart unless-stopped \
+  image: ex0nuss/XXX
+```
+
+## Parameters and environment variables
+Container images are configured using parameters passed at runtime (such as those above). There is no config file needed.
+Parameter / Env var | Optional | Default value | Description | 
+------------ | ------------- | ------------- | -------------
+`network_mode: host` | no | / | The container’s network stack is not isolated from the Docker host. This is necessary to send WOL packages from a container. The port of the webserver is configures via `APACHE2_PORT`.
+`APACHE2_PORT` | yes | 8080 | Port of the webinterface.
+`PASSPHRASE` | yes | admin | Password of the webinterface.
+`RWSOLS_COMPUTER_NAME` | no | / | Displaynames for the computers (**array**)
+`RWSOLS_COMPUTER_MAC` | no | / | MAC addresses for the computers (**array**)
+`RWSOLS_COMPUTER_IP` | no | / | IP addresses for the computers (**array**)
+`RWSOLS_SLEEP_PORT` | yes | 7760 | This is the Port being used by the Windows SleepOnLan Utility to initiate a Sleep State (**not necessary for WOL only**)
+`RWSOLS_SLEEP_CMD` | yes | suspend | Command to be issued by the windows sleeponlan utility (**not necessary for WOL only**)
+
+#### Explanation: Configuring the destination computer name, MAC and IP
+To configure the computers we want to wake, we will you these three environment variables:
+- `RWSOLS_COMPUTER_NAME`
+- `RWSOLS_COMPUTER_MAC`
+- `RWSOLS_COMPUTER_IP`
+
+Let's say we want to wake 2 computer in the end with the following configurations:
+1. PC1
+   - Displayname: PC of Mark
+   - MAC address: 24:00:dd:5a:21:04
+   - IP address: 192.168.1.146
+2. PC2
+   - Displayname: PC of John
+   - MAC address: 59:3c:45:3c:30:f6
+   - IP address: 192.168.1.177
+
+To configure the env vars it's easire to image it in a table:
+>RWSOLS_COMPUTER_NAME | RWSOLS_COMPUTER_MAC | RWSOLS_COMPUTER_IP
+>------------ | ------------- | -------------
+>PC of Mark | 24:00:dd:5a:21:04 | 192.168.1.146
+>PC of John | 59:3c:45:3c:30:f6 | 192.168.1.177
+
+Now you just format the table in an array:
+>```
+>      - RWSOLS_COMPUTER_NAME="PC of Mark","PC of John"
+>      - RWSOLS_COMPUTER_MAC="24:00:dd:5a:21:04","59:3c:45:3c:30:f6"
+>      - RWSOLS_COMPUTER_IP="192.168.1.146","192.168.1.177"
+>```
+It's important to use the format as show above: `"XXX","XXX"`
