How can i add multiple ports
I have nodejs and django application
webapp:
image: "python-node-buster"
ports:
- "8001:8000"
command:
- python manage.py runserver --noreload 0.0.0.0:8000
networks:
- django_network
node:
image: "python-node-buster"
ports:
- "3000:3000"
stdin_open: true
networks:
- node_network
ngrok:
image: wernight/ngrok:latest
ports:
- 4040:4040
environment:
NGROK_PROTOCOL: http
NGROK_PORT: node:3000
NGROK_AUTH: ""
depends_on:
- node
- webapp
networks:
- node_network
- django_network
networks:
django_network:
driver: bridge
node_network:
driver: bridge
Assuming i get the url for node at http://localhost:4040/inspect/http
http://xxxx.ngrok.io
and in my nodejs application, i want to access
http://xxxx.ngrok.io:8001
for apis
How to configure this

I use Datastax Java driver to connect cassandra in client service, which also runs inside docker.
CqlSession.builder()
.addContactEndPoint(new DefaultEndPoint(
InetSocketAddress.createUnresolved("cassandra-db",9042)))
.withKeyspace(CassandraConstant.KEY_SPACE_NAME.getValue())
.build()
I use DNS name to connect but not connected, i tried with Docker IP of cassandra container, and depends-on also.
Any issue with docker-compose file?
maybe someone can help me.
I have keycloak, my nodejs-server, and traefik all installed with docker-compose. Everything seemed to be fine until I called a route from my frontend to the nodejs API. No matter what I tried I get a 403 all the time. When the nodejs server is running not in a docker it works. Strange in my opinion.
Here my Docker Compose if it helps:

I also tried static ip addresses for nodejs and keycloak -> didn't work.
Here on StackOverflow someone mentioned using https would help -> didn't work
Pretty much my situation: Link . The goal for me is that even the API is reachable through traefik
Btw my angular frontend can communicate with keycloak. Also in a docker. I can also ping the keycloak docker from the nodejs docker. Nodejs configuration parameters directly form keycloak.
I really don't know what to do next.
Did someone tried something similar?
I've built two NEST app which shares a common database. I've been trying to figure out a way to make these two apps to get data from the Mongo db container. I'm stuck with this process.

I need help in making these app communicate with common container - mongodb
Click link for Architecture Setup
Since you're using 2 different docker-compose.yml you're actually running 2 backend and 2 mongodb on 2 docker-networks
One of the 2 mongo won't start cause the port is already occupied.
Option 1 (nicer):
services:
backend_1:
...
ports:
- '8888:8888'
backend_2:
...
ports:
- '8899:8899'
mongodb:
ports:
- '27017:27017'
This setup provides 3 container on the same network.
Now you can access at mongo from both backends at <mongo_ip>:27017
Option 2 (ugly):
services:
backend:
...
ports:
- '8888:8888'
mongodb:
ports:
- '27017:27017'
And in another docker-compose
services:
backend:
...
ports:
- '8888:8888'
This setup provides 3 container on 2 different network.
In this setup each docker-compose.yml has it's own docker network, so from the second backend service you have to connect to another docker network to access the container.
i'm kinda new to docker so sorry if my terminology is a little wrong. I'm in the process of getting my app to run in docker. Everything is starting up and running correctly but i'm unable to set the ip address that the services are running on. I need to do so since i'm making api calls that previously referenced a static variable in my js code. The spark service especially is important for me to have a knowable ip, as of now its randomly assigned.
docker-compose.yml
version: '3.0' # specify docker-compose version
services:
vue:
build: client
ports:
- "80:80" # specify port mapping
spark:
build: accubrew-spark
ports:
- "8080:8080"
express:
build: server
ports:
- "3000:3000"
links:
- database
database:
image: mongo
ports:
- "27017:27017"```
When you're running containers using docker-compose it creates a user-defined network for you and docker provides an embedded DNS servers, each container will have a record resolvable only within the containers of the network.
This makes it easy for you to know how to contact each service by just calling them by the name you specified on your docker-compose.yml.
You can try this:
version: '3.0' # specify docker-compose version
services:
vue:
build: client
ports:
- "80:80" # specify port mapping
spark:
build: accubrew-spark
ports:
- "8080:8080"
networks:
my_net:
ipv4_address: 172.26.0.3
express:
build: server
ports:
- "3000:3000"
links:
- database
database:
image: mongo
ports:
- "27017:27017"
networks:
my_net:
ipam:
driver: default
config:
- subnet: 172.26.0.0/16
But yours spark port is localhost:8080, if you need to expose other port with the ip 172.26.0.0, you can do - "7077" or with the localhost: -"7077:7077" this is an example with the port 7077 expose:
version: '3.0' # specify docker-compose version
services:
vue:
build: client
ports:
- "80:80" # specify port mapping
spark:
build: accubrew-spark
ports:
- "8080:8080"
- "7077"
networks:
my_net:
ipv4_address: 172.26.0.3
express:
build: server
ports:
- "3000:3000"
links:
- database
database:
image: mongo
ports:
- "27017:27017"
networks:
my_net:
ipam:
