If someone could guide me into the right direction I would really appreciate it. I'm not necessarily looking for a complete solution. which I would run as docker-compose up -scale agent=n. # no control over this as this is an existing image from docker hub But if I get the IP address of the container's nat connection, I can access the service in the container. Try and make a request to localhost:3000. My current docker-compose.yml (if that helps in any way) version: '3' So this IP address MIGHT be visible to other machines on your network or MIGHT only be visible to other Docker containers running on the same host machine. Run docker run -d -p 3000:443 7c20ca56ea4c to run the container and expose port 443 as port 3000 on the local machine. Containers with open connections to the old container close.
#DOCKER IP ADDRESS OF ANOTHER CONTAINER HOW TO#
I just have no idea how to cross-access the container from my Apps container (by script) or if this is even possible and then force to restart it (like docker restart #hash does). The new container has a different IP address than the old one, but they have the same name. Open an environment prepared Terminal Enter the following command to get the IP address of the Docker Toolbox virtual machine: host> docker-machine ip default. Assign our target ip address to the interface: nsenter -t (docker-pid web) -n ip addr add 10.12.0.117/21 dev web-int. I just managed to create my first docker-compose. Start by bringing up the link inside the container: nsenter -t (docker-pid web) -n ip link set web-int up. I'm looking for a way to restart one of the Agents from within my App.
n x Instances/Containers of the same image (lets call it Agent).1 x Nodejs App in a Container (lets call it App).Here postgre 5432 is only exposed.Now set hostname as the container ip and it will work. You can access other exposed ports through this IP.
Do you see the problem already They are different, so you cannot simply run docker-compose up -d and all operating systems.
On Docker for Linux, the IP address of the gateway between the Docker host and the bridge network is 172.17.1 if you are using default networking. docker network inspect con Now you can see the IP address shown in the network inspect. Docker Tip - How to use the host's IP Address inside a. We’re only interested in the IP address though, so you can pass it a formatting option with -f to narrow it. This command gets connected container IP address and other details. Then, run docker inspect, which returns a huge JSON file with all the information about the container. Hard way: you either need to know the IP address of the other container and connect to this IP address. I have to say that I have close to 0 experience with docker. First, you’ll need to find the ID or name of the container you want to get the information for, which you can do with: docker ps. I'm in a planning phase for a little tool for myself.
