Fa'apipi'i Docker

Fa'aaliga: O pusa Docker o loʻo mulimuli mai e tatau ona faʻaaogaina ma RCPs fausia e faʻaaoga ai le Simplicity Studio 5 mo se faʻasalaga tuʻuina atu. Ia mautinoa e fetaui ma le koneteina tag version ma le GSDK version o lo'o e fa'aogaina mo su'ega.
Silicon Labs fautuaina le faʻaogaina o le Docker container a le kamupani ma le OTBR. O le fa'agaioia o le OTBR i totonu o se atigipusa e mafai ai ona fa'atupuina mea fa'aoga faigofie ma fa'ata'ita'iga vave ma su'ega.
Silicon Labs o loʻo tuʻuina atu pusa Docker muamua na fausia (faʻatasi ma tags), talimalo ile DockerHub: https://hub.docker.com/r/siliconlabsinc/openthread-border-router/tags

Mo le lagolago leitio fa'apitoa (fa'asa'oloto alpha):
https://hub.docker.com/r/siliconlabsinc/openthread-border-router-proprietary-na-915/tags

Mea e mana'omia muamua

• I luga o le SD card, ia mautinoa e moli le ata Raspberry Pi OS Lite poʻo Raspberry Pi OS ma Desktop.
• Ia mautinoa e faʻafou fale teu oloa ma pusa pusa (apt-get update ma apt-get upgrade aʻo leʻi faʻapipiʻi Docker).
• Filifili ae fautuaina: Faʻapipiʻi Haveged mo tulaga entropy sili atu.

Fa'atonu Taiala

Fa'aaliga: Sui le manoa i poloaiga o lo'o mulimuli mai ma le fa'amatalaga moni o lo'o e fa'aogaina. Mo example, gsdk-4.4.0, sisdk- 2024.6.0, ma isi.

• Ia mautinoa e toe faʻafou pe a uma ni faʻafouga:
  curl -sSL https://get.docker.com | sh
• A maeʻa, e mafai ona e suia le faʻaoga a le Docker e le manaʻomia ai le sudo i luma o faʻatonuga taʻitasi:
  sudo usermod -aG docker $USER
• Rasipi Pi ma Linux tagata faʻaoga, ia mautinoa e tamoe:
  sudo modprobe ip6table_filter
  mo OTBR firewall lagolago. Ole mea lea e mafai ai e tusitusiga a le OTBR ona fai tulafono i totonu ole koneteina Docker aʻo leʻi amataina le otbr-agent.
  Ina ia mautinoa o loʻo faʻaauau pea lenei seti i le va o le toe faʻaleleia, faʻaopoopo le laina lea i /etc/modules:
  ip6table_filter
  Afai e le maeʻa lenei laasaga, e mafai ona faʻaalia mea sese modprobe pe a amataina se pusa Docker.
• Tuuina atu tulafono nei e faʻapipiʻi ai pusa. Manatua e na'o le tasi le koneteina o le Alalaupapa Tuaoi e mafai ona tamo'e i le taimi e tasi ma le RCP. E le gata i lea, ia mautinoa e faʻamaonia le RCP version (Thread protocol version 1.4) e tatau ona faʻasaga i lenei pusa.
• UART fa'aoga:
  toso e faife'au le siliconlabsinc/openthread-border-router:
• SPI fa'aoga:
  toso e faife'au le siliconlabsinc/openthread-border-router: _spi
• Ina ia faʻataʻitaʻiina se OpenThread Border Router (faʻaogaina ole Thread protocol version 1.4), tuʻuina atu le poloaiga lenei:
• Example mo UART interface
  docker run -d –igoa “otbr” \
  –sysctl “net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1” \
  -p 8080:80 –dns=127.0.0.1 -it \
  –volume /dev/ttyACM0:/dev/ttyACM0 \
  –le siliconlabsinc/openthread-border-router: \
  –leitio-url “spinel+hdlc+uart:///dev/ttyACM0” \
  –ivi tua-fegasolo eth0
  (Vaai vaega 3.2.2 ma le 3.2.2.1 mo faʻamatalaga i le faʻatulagaina o le UART Radio URL)
•  Example mo le SPI interface (mo nisi fa'amatalaga, va'ai vaega 3.2.3 OTBR Configurations e fa'aaoga ai le SPI Interface)
  docker run -d –igoa “otbr” \
  –sysctl “net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1” \
  -p 8080:80 –dns=127.0.0.1 -it \
  –volume /dev/spidev0.0:/dev/spidev0.0 \
  –le siliconlabsinc/openthread-border-router: \
  –leitio-url “spinel+spi:///dev/spidev0.0?gpio-int-device=/dev/gpiochip0&gpio-int-line=21&gpio-reset-de-vice=/dev/gpiochip0&gpio-reset-line=20&no-reset=1&spi-speed=1000000” \
  –ivi tua-fegasolo eth0

(Silasila i le vaega 3.2.3 OTBR Configurations e fa'aaoga ai le SPI Interface mo fa'amatalaga i le fa'atulagaina o le SPI Leitio URL.)
Fa'aaogā fa'aupuga fa'aopoopo e fa'atulaga ai pusa. Mo nisi fa'amatalaga, va'ai 3.2.9.3 po'o le Dockerfile i le ot-br-posix installa-tion directory.

Docker Configuration Notes

Fa'aaliga: Silicon Labs-hosted Docker containers e tatau ona faʻaaogaina ma RCPs fausia e faʻaaoga ai le Simplicity Studio 5 mo se tuʻuina atu.
Ia mautinoa e fetaui ma le koneteina tag version ma le GSDK version o lo'o e su'eina.
Manatua: Sui le manoa i poloaiga o lo'o mulimuli mai ma le fa'amatalaga moni o lo'o e fa'aogaina. Mo example, gsdk-4.4.0, sisdk- 2024.6.0, ma isi.

• Fa'atulaga le uafu TTY mana'omia mo le OTBR e fa'afeso'ota'i le RCP i le amataga. Su'e le uafu TTY o le masini RCP. O le auala pito sili ona faigofie e fai ai lenei mea o le suʻeina lea o se /tty/dev… ulufale pe a fesoʻotaʻi le RCP. E tatau ona avea ma /dev/ttyUSB0 poʻo /dev/ttyACM0.
• Faʻatonu le faʻapipiʻiina o Docker e pei ona taua i lalo (example mo UART interface):
  docker run -d –igoa “otbr” \
  –sysctl “net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1” \
  -p 8080:80 –dns=127.0.0.1 -it \
  –volume /dev/ttyACM0:/dev/ttyACM0 \
  –le siliconlabsinc/openthread-border-router: \
  –leitio-url “spinel+hdlc+uart:///dev/ttyACM0” \
  –ivi tua-fegasolo eth0
• -d faʻamautinoa o loʻo alu le koneteina i le tuʻu ese.
• Review o ogalaau tamo'e mo le koneteina i so'o se taimi e fa'aaoga ai le fa'atonuga o fa'atonuga.
• –e pipii le igoa se'ia tapuni lelei (pe aveese)
• O le Port 8080 o loʻo faʻaalia ai le taulaga o le web 'au'aunaga o lo'o fa'afeiloa'i le pulega o le Fa'aola Border webitulau.
• Tuuina atu faʻatonuga saʻo i le koneteina e aunoa ma le faʻapipiʻiina i ai: docker exec -ti otbr sh -c "sudo ot-ctl state"
  Mo nisi faʻamatalaga, vaʻai i le docker exec documentation.
• Maua saʻo se atigi fesoʻotaʻiga i luga e ala i le tuʻuina atu o lenei poloaiga: docker exec -ti otbr sh -c "sudo ot-ctl"
• Siaki le faʻamalama o loʻo faʻaogaina le pusa OTBR Docker mo le faʻaogaina o le ogalaau o le Border Router, pe mulimuli i le pusa pusa e pei ona taua i lalo:
  ogalaau tufuga [container-id] -f
• Pulea pusa e pei ona fa'aalia i lalo pe afai e le sa'o le utaina:
  # lisi ata uma o pusa
  ata faufale otbr
  # aveese pusa o iai
  ata faufale rm -f
  # lisi pusa o lo'o ta'avale
  tagata faigaluega ps -a
  # e aveese le atigipusa o loʻo taʻavale
  tagata faigaluega rm -f
