[08:29:23]<mstenta>svenn: (regarding Docker) I haven't tried installing Docker on a Pi before - I'm not sure what the recommended approach is
[08:30:04]<mstenta>Please share your experience! I'm curious - and a lot of people have asked about running farmOS on a Pi
[08:31:10]<mstenta>(Feel free to create an issue in the Github repo to keep track of it if that is helpful)

[10:34:41]<svenn>Reading myself up on Docker. Walk the walk and talk the talk.
[10:44:34]* trentf has joined #farmos
[10:54:05]<mstenta>svenn: i like the idea of Docker a lot... basically allows you to package all dependencies together
[10:54:28]<mstenta>so you can, for example, install apache, php, mysql, etc for farmOS - but not directly on the host system
[10:54:48]<mstenta>therefore, it makes it easy to run different versions of php for different applications, for example
[10:55:25]<mstenta>and for farmOS specifically, it's really helpful to be able to say "here is a docker image that has everything you need"
[10:55:36]<mstenta>and know that it will run wherever docker is able to run

[13:47:40]<svenn>well, I read somewhere that the docker container is actually machine architecture dependent.
[13:47:53]<svenn>and that each container can only run one process
[13:48:14]<svenn>so there must be one container for php,, one container for apache and one container for farmos
[13:48:24]<svenn>and one container for mysql
[13:48:31]<mstenta>svenn: that is partially true
[13:48:40]<svenn>but then it should be possible to only update the farmos container
[13:48:41]<mstenta>it is best practice to put one process in each container... but not required
[13:48:52]<mstenta>the farmOS container is apache+php
[13:49:01]<mstenta>and it requires that you also set up a separate mysql/mariadb container
[13:49:09]<mstenta>(the docker-compose.yml file that comes with farmOS will do that automatically)
[13:49:31]<svenn>well, I only have one container farmos/farmos
[13:49:43]<svenn>and I think it is x86
[13:49:45]<mstenta>but in general, each container is essentially a mini linux box... you can get into it in a bash shell and look around like ssh
[13:49:59]<mstenta>and each container is a separate environment from each other
[13:50:20]<svenn>the linux is supposed to be outside the container in my mind
[13:50:54]<svenn>but I am just starting to scratch the surface of the container ship
[13:50:54]<mstenta>the kernel is, but everything else is in the container... that's my understanding but i might be wrong
[13:51:53]<svenn>I guess the farmos/farmos I pulled onto my raspberry pi is built on x86_64 linux
[13:52:26]<mstenta>ah ok yes... so that is my biggest question about docker on pi... because pi is ARM
[13:52:39]<mstenta>maybe we will need to provide another image for ARM
[13:52:50]<svenn>and pi 2 and 3 are different archs than pi1
[13:53:02]<mstenta>oh really? didn't know that
[13:53:05]<mstenta>they aren't ARM?
[13:53:15]<svenn>there are some subltle differences on those arms
[13:53:28]<svenn>armv6 and armhf
[13:53:29]* efraim has quit (Remote host closed the connection)
[13:53:42]<mstenta>oh ok
[13:53:45]* efraim has joined #farmos
[13:53:48]<svenn>I think, but I don't know for 100% sure
[13:54:14]<svenn>I have been looking at all kinds of obscure error messages and blogs this weekend
[13:54:47]<svenn>so I may have information overload in my brain
[13:55:36]<svenn>gtg
[13:55:45]<mstenta>ok thanks Svenn! good luck!
