MM with Docker

[RonR]

@sdetweil Sam, I saw your module yesterday while browsing the 3rd party modules list. I will definitely take download your module. Thanks.

[RonR]

@sdetweil Sam, It is working WOW. :) Now the question is can I move the modules I have on the old system over to this one and modifiy the config file? I’m going to install your config module also.

@RonR Generally speaking yes, but I would suggest to redownload / clone your modules to have the most-up-to-date version. Apart from this you also need to run the corresponding npm install for each of your modules…

[sdetweil]

@RonR you can move the config file.

the modules are a little tougher under docker.
the git clone and npm install for each needs to be done from INSIDE the docker container

ssh to your docker host (my synology nas, your pi)

then

docker exec -it mm bash 

to get to the commandline inside the container

then cd modules

then do the normal git clone/cd/npm install cycle for each module
then exit to leave the container, and
cd ~/magicmirror/run
docker compose restart mm

add MMM-Config on this whole process (clone/cd/npm install)
then you won’t have to do this again

also have to update the run/compose.yaml
to add the extra ports for MMM-Config (see the readme)

@sdetweil Sam, I installed your config module but it does not display on the screen. I tried moving it to the bottom-right but no difference. I tried to reinstall it w/ npm install, no help.

This is the portion of the config.js for MMM-config. I added the restart entry because I wanted it to restart after an change to the file.
{
module:“MMM-Config”,
position:“bottom_right”,
// the QR code (if requested) will appear here
config:{
restart:“docker”,
}
{,

As far as I know I have followed all the directions.

@RonR

from the doc on parms

showQR	OPTIONAL	false	Show a QR code on the MM screen to allow quick access to the configuration form
===>	Otherwise, use a browser to open http://MM_IP_Address:MM_Port/configure

only the QR code is displayed on the UI

the module installer is at

http://MM_IP_Address:MM_Port/installer

[RonR]

@schlomm Thanks, I understand, download new module files.

@sdetweil Sam, I can’t believe how simple it was and I just over looked it in the docs. Thanks for being so patient with me.

[sdetweil]

@RonR you weren’t looking there, no biggie…

but your experience tells me I need to make it more clear…
will update the doc…

[sdetweil]

I added this section to the doc
after the parms and before the 1st screenshot

@RonR hello. I did the same a while back and @sdetweil 's help and contribution is great!

I was trying to run two different MMs in two containers. The 2nd one was always seeing the same configs as the first(or something like that) even though though I was able to configure two different ports, one for each, but wasn’t able to run two different screen layouts.

This is what docker spooked be able to enable. Multiple parallel setups, then you just run a series of screens in kiosk mode and you can display the same setup on multiple locations and screens.

Maybe I’ll try again. I pasted about it here, and Sam did try to help. I gave up on it.

[sdetweil]

@OrangeMirror the current docker setup will only work for multiple instances

IF

you use the MM_CONFIG_FILE environment variable to run instances off different config files,
or
the MM_PORT env variable to override the port if using the same config.js

all the files will come from the ONE folder tree ~/magicmirror

so this means you would have to setup multiple entries in the compose.yaml to launch multiple instances (with the different config parms)

You have to change the container name too

this is because all the DATA used by the container is external (on docker host filesystem) and not IN the container

an example NOT using docker, but same idea here
