I have application installed in VM (centOS7) running on Oracle Virtual box with "Bridge Network" while communicating internal containers using : http://host.docker.internal:6001(other container port) it is throwing error saying #
request to http://host.docker.internal failed, reason: ETIMEDOUT 172.17.0.1:6001"
where as the same application while running in local I am able to connect to : http://host.docker.internal.
please help

This is all you need in the docker-compose.yml. Replace 172.17.1.xx with the ip of your database server. In your application refer to the database host by db.
I want to setup a local hive server and found this repo:

This is the yaml file I use.

The ports >50000 are blocked on windows, I don´t have admin rights on my company pc, so I tried to map the ports like this:
ports:
- "40070:50070"
environment:
SERVICE_PRECONDITION: "namenode:40070 datanode:40075 hive-metastore-postgresql:5432"
This will let me get the Container started, but the container seem not to be able to communicate.
hive-metastore_1 | [1/100] check for namenode:40070...
hive-metastore_1 | [1/100] namenode:40070 is not available yet

956a5237dbe2_docker-hive_datanode_1 | [4/100] namenode:40070 is not available yet
I tried to change both ports:
ports:
- "40070:40070"
This will not work, because some IPs seem to be hardcoded:
ded7410db1b9_docker-hive_namenode_1 | 21/10/08 12:39:05 INFO hdfs.DFSUtil: Starting Web-server for hdfs at: http://0.0.0.0:50070
ded7410db1b9_docker-hive_namenode_1 | 21/10/08 12:39:05 INFO http.HttpServer2: Jetty bound to port 50070
Does anyone know how to get this running?
With the following:
ports:
- "40070:50070"
all you are doing is directing traffic from host port 40070 to container port 50070.
So to access "namenode" from the host machine for example:
localhost:40070
And to access "namenode" inside the compose network:
namenode:50070
Service precondition with BDE checks the container and the port repeatedly to see if the service is running before setting up its own services to ensure things are ready first. You have not changed the port running on the container, so your containers should still communicate via port 50070.
You have incorrectly changed the precondition to scan instead for your host port 40070, whereas it should look for the internal network container port 50070 regardless of host port.
Change it to the following:
ports:
- "40070:50070"
environment:
SERVICE_PRECONDITION: "namenode:50070 datanode:50075 hive-metastore-postgresql:5432"
You can change the operating ports on Hive etc. with the environmental variable file provided, but you shouldn't need to. Exposing host port 40070 to container port 50070 has no impact on the operation of the docker services.
I have this docker-compose.yml file from here that I am using to open selenium hub and node on mac OS . I changed host port to 65299 , as I got error that 4444 is being used. I have docker desktop 3.5.1 installed
version: "3"
services:
selenium-hub:
image: selenium/hub
container_name: selenium-hub
ports:
- "65299:4444"
chrome:
image: selenium/node-chrome
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=65299
firefox:
image: selenium/node-firefox
depends_on:
- selenium-hub
environment:
- HUB_HOST=selenium-hub
- HUB_PORT=65299
When I look here - http://localhost:65299/grid/console , I dont see any node registered
Also, on terminal I get this
firefox_1 | 20:27:22.110 INFO [SelfRegisteringRemote$1.run] - Couldn't register this node: The hub is down or not responding: Failed to connect to selenium-hub/172.26.0.2:65299
Also , in logs it says
Nodes should register to http://172.27.0.2:4444/grid/register/
so why is system even trying 172.26.0.2:65299 or may be I am missing something here ?
The HUB_PORT variable of nodes are wrong. 65299 port is the port for accessing hub from outside of docker network. For example you are using this port the access hub from browser.
You need to set 4444 to that variable. That port available to docker network. So nodes can connect hub.
I'm using this https://github.com/wernight/docker-ngrok , so that my dockerize app will expose to internet. I added it to my docker-compose, but when I up my container I get this error "Failed to complete tunnel connection". when I want to access my app I do it like this myapp.local and it works find because I set up windows host. when I access like this http://localhost I see this , I noticed I cannot access using localhost that's why I used windows host.
Here is my docker-compose
web:
image: nginx:stable
container_name: webcontainer
ports:

volumes:

external_links:

ngrok:

ports:

I'm trying to map a port from my container, to a port on the host following the docs but it doesn't appear to be working.
After I run docker-compose -f development.yml up --force-recreate I get no errors. But if I try to reach the frontend service using localhost:8081 the network is unreachable.
I used docker inspect to view the IP and tried to ping that and still nothing.
Here is the docker-compose file I am using. And I doing anything wrong?

You are using docker toolbox. Docker toolbox uses docker machine. In Windows with docker toolbox, you are running under a virtualbox with its own IP, so localhost is not where your containers live. You will need to go 192.168.99.100:8081 to find your frontend.
As per the documentation on docker machine(https://docs.docker.com/machine/get-started/#run-containers-and-experiment-with-machine-commands):
$ docker-machine ip default
192.168.99.100
