### Instalación de octoprint en docker
|
|
|
|
___Pronterface___ se ha vuelto imposible de instalar para mi, así que vamos a probar ___Octoprint___ dockerizado, así ya lo tenemos controlado para instalarlo en una _Orangepi Zero_ en la propia impresora.
|
|
|
|
El fichero `docker-compose.yml` para el Octoprint (cortesía de Caligari):
|
|
|
|
```yml
|
|
version: '2.4'
|
|
|
|
services:
|
|
octoprint:
|
|
image: octoprint/octoprint
|
|
container_name: octoprint
|
|
restart: unless-stopped
|
|
network_mode: bridge
|
|
ports:
|
|
- "80:80"
|
|
devices:
|
|
- "/dev/bus/usb"
|
|
volumes:
|
|
- "./data:/octoprint"
|
|
- "/run/udev:/run/udev:ro"
|
|
device_cgroup_rules:
|
|
- "c 188:* rmw" # USB to serial
|
|
- "c 81:* rmw" # USB webcams
|
|
# uncomment the lines below to ensure camera streaming is enabled when
|
|
# you add a video device
|
|
#environment:
|
|
# - ENABLE_MJPG_STREAMER=true
|
|
|
|
####
|
|
# uncomment if you wish to edit the configuration files of octoprint
|
|
# refer to docs on configuration editing for more information
|
|
####
|
|
#config-editor:
|
|
# image: linuxserver/code-server
|
|
# ports:
|
|
# - 8443:8443
|
|
# depends_on:
|
|
# - octoprint
|
|
# restart: unless-stopped
|
|
# environment:

Tenemos que adaptar la parte del mapeo del puerto USB para usarlo en nuestro ordenador.
|
|
|
|
A continuación algunas notas de como se puede hacer el mapeo del puerto USB en nuestro ordenador.
|
|
|
|
```
|
|
|
|
|
|
|
|
DSM docker UI application does not have option to set "device".
|
|
|
|
But you still can do this by following steps:
|
|
|
|
create "octoprint" container with all settings you need (volumes, ports etc)
|
|
select "Settings" -> "Export" and export docker container configuration JSON to local computer
|
|
open exported JSON in any editor
|
|
find string
|
|
|
|
"devices" : null,
|
|
|
|
and replace it with
|
|
|
|
"devices" : [
|
|
{
|
|
"pathOnHost": "/dev/ttyUSB0",
|
|
"PathInContainer": "/dev/ttyUSB0",
|
|
"CgroupPermissions": "rwm"
|
|
}
|
|
],
|
|
|
|
Import JSON file back to DSM docker UI
|
|
|
|
P.S. Also I found that my "/dev/ttyUSB0" has "crw-------" permission, and can't be accessed inside docker by octoprint application. So I have to manually set to "crw-rw-rw-" with
|
|
|
|
chmod a+rw /dev/ttyUSB0
|
|
|
|
|

|
|
also
|
|
|
|
|
|
|
|
Suggest adding instructions to to identify the USB port being used and then passing this device into the container.
|
|
|
|
With the pi connected to the printer via usb
|
|
ls /dev | grep tty
|
|
|
|
This should return a long list of 'tty' The one we need is found at the end of the list and is probably
|
|
ttyUSB0 if no other USB devices are plugged in.
|
|
|
|
In order to use this ttyUSB0 add this to your docker run command
|
|
|
|
docker run -device /dev/ttyUSB0:/dev/ttyUSB0 .....
|
|
|
|
Now octoprint can detect the the USB port and connect to the printer.
|
|
|
|
Hi
|
|
i installed everything and it works. unfortunately I can't enable the usb and launching the command (pi4): docker: invalid reference format: repository name must be lowercase.
|
|
See 'docker run --help'.
|
|
|
|
some advice?
|
|
