about how to configuration for WOL docker-compose.yml

[zukkie777]

WakeOnLAN function was released in version 1.2.0.
http://guacamole.apache.org/releases/1.2.0/

But I couldn't get WOL to connect to my computer, with settings using docker-compose.yml.

I created some yml files and tested the connection,
Error was output and the WOL connection could not be established.

Please help me.

Thank you.

If it works with the regular docker file you can get it working with docker-compose. - But, WOL is not something you should expect from my docker-compose setup. You might have to do some additional setup yourself. WOL is not part of my tiny project.

[zukkie777]

I self-solved, about the WOLof guacamole.

If you like it, please refer to it.

added WOL section to README.MD and linked to the mailinglist entry.

[zukkie777]

Thanks for comment.
I had updated yml file.

This site is not reachable, can we have the solution in the README?

Hi, today I tested to start all containers in network mode host according above post, but did not make it. Actually guacd container sends WOL packets and only his network should be outside the bridge. I think the resolution is more easy. Only guacd container "move" to host network, others containers (guacamole and postgres works in bridge mode). Just tell guacamole to connect guacd by IP -(GUACD_HOSTNAME: {host`s ipaddress}; GUACD_PORT: 4822) and of corse remove links to guacd.

Hi Tonytvbg,
please, can you be more specific. How did you edit your docker-compose.yml?

[tonytvbg]

Here is my compose file. Of course the password and guacd IP must be set properly:
version: '2.0'

Hi all,

after a lot of tinkering and the help of several ressources on the web, I managed to get a docker setup with usable Wake On LAN.

My biggest help was the info posted by tonytvbg, so thank you mate !

As it took me quite some time to aget everything working, I thought I too would share my compose file here.
It has been working ok on my Synology NAS with the Sync Reverse Proxy (no nginx used in Docker).
I use Portainer and its "Stack" functionality for deployment.

In this first part, I have adapted some steps taken from the prepare.sh script (maybe some commands are not really necessary).

TODO before deploying the stack !!!!!!!! use SSH and root on the NAS !!!!!!

# mkdir /volume1/docker/guacamole/postgres/init >/dev/null 2>&1
# chmod -R +x /volume1/docker/guacamole/postgres/init
# docker run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --postgresql > /volume1/docker/guacamole/postgres/init/initdb.sql
# chmod 777 /volume1/docker/guacamole/postgres/init/initdb.sql
# chmod +x /volume1/docker/guacamole/postgres/init/initdb.sql
# mkdir /volume1/docker/guacamole/postgres/data
# mkdir /volume1/docker/guacamole/guacamole/etc
# chmod -R 777 /volume1/docker/guacamole/guacamole/etc
# mkdir /volume1/docker/guacamole/guacamole/home
# chmod -R 777 /volume1/docker/guacamole/guacamole/etc

And here is the compose file with a bit cleaner look compared to the one tonytvbg posted ;-)

I'm really happy now with my setup, I can access different machines remotely without having to keep them on all the time. 👍
