How to install this plugin in a docker container

[Sen5ation]

Hi,

I do have a node-red docker container. How can I install this in a docker container? I did not find a how to in the wiki or via Google. Have you guys any tips?

my docker-compose.yml looks like this:

---
services:
  nodered:
    image: nodered/node-red
    container_name: nodered
    user: "1004"
    restart: unless-stopped
    ports:
      - 'LOCAL_IP:1180:1880'
    volumes:
      - /docker/nodered/container_data/:/data

I would offer 3 different ways to achieve this:

1. Install it from the UI by using the Node-RED manage palette

2. Execute the installation within the docker container using: docker-compose exec nodered bash Then navigate to data directory and run: npm install node-red-contrib-amazon-echo

3. Use an init container which will install the module before starting the Node-RED service.

   version: '3'
   services:
   nodered:
   image: "nodered/node-red:latest"
   environment: {}
   ports:
     - "1880:1880"
   volumes:
     - type: bind
       source: ./data
       target: /data/
   restart: unless-stopped
   depends_on:
     nodered-init: 
       condition: service_completed_successfully
   
   nodered-init:
   image: "nodered/node-red:latest"
   volumes:
     - type: bind
       source: ./data
       target: /data/
   entrypoint: 
     - "/bin/sh"
     - "-c"
     - "cd /data && npm install node-red-contrib-amazon-echo"

Thanks for the fully automated option nr 3. Although the other options will achive the same result I highly prefer the option 3 as it is fully automatic . I do have some issues with this option however. I hope you can give me a hint to a solution.

This is my compose file:

services:
  nodered:
    image: "nodered/node-red:latest"
    #environment: {}
    user: "1004"
    ports:
      - 'LOCALIP:1180:1880'
    volumes:
      - type: bind
        source: /docker/nodered/container_data/
        target: /data/
    restart: unless-stopped
    depends_on:
      nodered-init:
        condition: service_completed_successfully

  nodered-init:
    image: "nodered/node-red:latest"
    volumes:
      - type: bind
        source: /docker/nodered/container_data/
        target: /data/
    entrypoint:
      - "/bin/sh"
      - "-c"
      - "cd /data && npm install node-red-contrib-amazon-echo"

running /usr/bin/docker-compose --verbose -p docker-nodered -f /docker/nodered/compose_files/compose.yml up --force-recreate I get this error:

ERROR: for nodered  Container "a004fe4a0700" exited with code 2.

Do I see it correctly that the "Args" looks fine: 'Args': ['-c', 'cd /data && npm install node-red-contrib-amazon-echo'], But in the Entrypoint there is the "node-red-contrib-amazon-echo" missing?: 'Entrypoint': ['/bin/sh','-c','cd /data && npm install ' or is that cut by the docker engine/output?

I understand the logic what is done by the init container/service, but I do not know why it does not function :/

You can use the following steps to debug the nodered-init container, as it appears to have exited with code 2:

docker-compose down
docker-compose up
docker-compose logs nodered-init

thanks a lot :)

as long as the urls http://IP/api/description.xml and http://IP/description.xml are accessable though Port 80 and the nodered and the amazon echo are on the same network, it should do right?

Is there something special I need to take care of when I am switching the nodered installation from one host/IP to another? Other than deleting the devices in alexa? It should discover them, right?

[datech]

That's correct. The Node-RED Docker container needs to use the host network for the SSDP discovery process to work correctly. Echo devices and the Docker host must be on the same broadcast domain, and Echo devices will try to access the hub on port 80
