Change port with docker

ChirpStack (v4) Setup and configuration
1

Hi
I’m trying to run ChirpStack with docker compose and I faced problem with port changing. When I change ports for and in standard docker-compose configuration, I get errors like this. Ports 20246 and 30246 are both open and can’t handle TCP and UDP transition. I can’t open ports 8080 and 1700 on my VPS.
I tried to change port 8080 to 20246 manually in ChirpStack config to 20246, but also get errors.

Maybe someone have idea why I have such strange error?

Looks more like a docker issue than a Chirpstack issue to me, maybe ensure you have gone through the docker installation steps correctly and it is up to date. You might also get better luck posting on the docker forums.

Here’s an issue that seems related: Docker-compose giving 'ContainerConfig' errors after update today - Ask Ubuntu

If you don’t think that is the issue, the following configuration has worked for me in the past, you could give that a try:

Set your port bindings in the docker compose to 8081:8081 for Chirpstack and 1701:1701/udp for the bridge and then change the chirpstack.toml file to:

# API interface configuration.
[api]
    # interface:port to bind the API interface to.
    bind="0.0.0.0:8081"

and in your chirpstack-gateway-bridge.toml add the following section:

[backend]

# Backend type.
#
# Valid options are:
#   * semtech_udp
#   * concentratord
#   * basic_station
type="semtech_udp"


  # Semtech UDP packet-forwarder backend.
  [backend.semtech_udp]

  # ip:port to bind the UDP listener to
  #
  # Example: 0.0.0.0:1700 to listen on port 1700 for all network interfaces.
  # This is the listener to which the packet-forwarder forwards its data
  # so make sure the 'serv_port_up' and 'serv_port_down' from your
  # packet-forwarder matches this port.
  udp_bind = "0.0.0.0:1701"
