#Docker – Sobre puertos, IPs y mas para acceder a un container alojado en #RaspberryPi

Buenas !

Mi proyecto de CustomVision.ai esta compilado y ejecutándose en Docker en Raspberry Pi 3. Ahora llega el momento de utilizar el mismo desde aplicaciones en otros dispositivos, y para este caso, todos en la misma red.

Cuando ejecute mi imagen, utilice parámetros para definir la IP y los mapeos de los puertos de la misma. El siguiente comando es muy útil para ver esta información en un container.

sudo docker port <CONTAINER ID>

01 docker port

Mi container esta registrado en la dirección IP 127.0.0.1 y utiliza el puerto 80. Esto es genial para procesos locales, sin embargo no permite que este container sea accedido desde otros devices.

Lo ideal es no registrar la direccion IP local 127.0.0.1 y solo definir el mapeo de puertos 80:80. En este caso ejecuto mi imagen con el siguiente comando

sudo docker run -p 80:80 -d <IMAGE ID>

02 docker port 80 and success run

El container utilizar el puerto 80, y Docker toma control de este puerto en la RaspberryPI. La dirección IP de la raspberry pi es [192.168.1.58], así que ya puedo realizar pruebas con Postman para analizar imágenes en la RPI.

Super cool. Un potente y barato server de análisis de imágenes basado en un proyecto de CustomVision por menos de $30 !

Happy coding!

#Docker – About ports, IPs and more to access a container hosted in a #RaspberryPi

Hi !

So, my CustomVision.ai image is build and running in a container in my Raspberry Pi 3. It’s time to see if I can use it from other devices in the same network. When I run my image I defined IP and Port, but if you want to know these information, the following command is very useful

sudo docker port <CONTAINER ID>

01 docker port

So, my container is listening at 127.0.0.1 in port 80. That’s cool for local processing, however I want to access my container from other devices in the same network. In order to do this, I’ll run my image with the following command (I’m not defining the IP, just the port 80)

sudo docker run -p 80:80 -d <IMAGE ID>

02 docker port 80 and success run

The container is using the port 80, and docker is taking over this port in my device. My Raspberry PI device IP is [192.168.1.58], so I can go back and make some tests using Postman to analyze images in the device.

That’s cool. A small CustomVision image analyzer server for less than $30 !

Happy coding!
