@RobCee i don’t think the image has python installed

[RobCee]

@sdetweil you are correct. It doesn’t have python installed with it.
My next challenge is to work out how to get that up and running.

Once I have it running I will get back to you on your module.

[sdetweil]

@RobCee short term while u are execed in, install python as usual

if you are using https://gitlab.com/khassel/magicmirror

he doesn’t provide a mechanism to add system components like python

[RobCee]

@sdetweil that works, but the setup refreshes itself by default, so it wouldn’t last too long.
I will work it through. Thanks

[sdetweil]

@RobCee while its challenging, its possible

I might open an issue of the docker image to allow a folder/file with additional packages to install at startup…

seems a waste to do it every refresh time tho

long ago and far away (2015) I had a product to install in an image, 1.5 GIG of product, and didn’t want to make a separate image for the different versions…

so I figured out how to install and capture that as a tarfile, and then
untar it as part of the startup…

then the start script passed that as a parm to startup, so I could change the product on the fly, using the same tiny image…

@sdetweil it may just be quicker for me to learn how to do what my python code does in .js
It probably isn’t that complex. It is only reading stuff from web services and reporting it locally. I had hoped I could skip that stage, but I guess there are no short-cuts.

[sdetweil]

@RobCee you can do most of the dev and test using a local file , outside of MM

xxx.js
then
node xxx.js

at least to get your main function working…

this code would work in the node helper

[RobCee]

@sdetweil super. thanks for the pointer.

@sdetweil

the docker image karsten13/magicmirror:latest doesn’t contain python. Simplest solution for this is to use the fat image karsten13/magicmirror:fat, for more infos: https://khassel.gitlab.io/magicmirror/images/

[sdetweil]

@karsten13 thanks… the doc needs help tho

The difference between latest and fat is image size and installed

those words are not used above that sentence, and so didn’t mean anything to me…

I would propose adding in front of that sentence

There are two images of each type created

latest and fat 
docker pull image_name:latest 
or
docker pull image_name:fat 

and then I would add a new line between these sentences

debian packages. For most use cases the latest image is sufficient. 
Some modules need dependencies which are not includes in latest, e.g
