I’m running into an issue with Docker on macOS Big Sur where I can’t access any server/API running inside a container by using 127.0.0.1. But it seems to work when I use localhost. The following what I’m running to demonstrate my problem I start an nginx container like so: docker run –name mynginx1 -p 80:80 ..
In the docker compose file i added api server as a service and mongodb is installed in my local pc. But when the api run in docker container it could not connect with 127.0.0.1:27017. Here is the docker-compose file. networks: test_network: name: test_network driver: bridge services: api: container_name: api build: ./api ports: – "3031:3031" networks: ..
I installed docker to install over a container for each site I created only that to access port 80 I need each container to have its own public IP. How can I create a bridge network to correctly assign each container its public IP? Currently I have seen that there is the subnet created by ..
The Docker Networking documentation states: subnet : Subnet in CIDR format that represents a network segment ip-range : Allocate container ip from a sub-range And the example shows: $ docker network create –driver=bridge –subnet=172.28.0.0/16 –ip-range=172.28.5.0/24 –gateway=172.28.5.254 br0 So, the subnet of from 172.28.0.0 to 172.28.255.255 And the ip-range is from 172.28.5.0 to 172.28.5.255 Why would ..
I am struggling with networks and Docker/docker-compose. Use case : I am using Transmission as a client Torrent, in network_mode with a wireguard VPN for privacy. Next to it, I have a Jackett container and a Sonarr container for automatisation. The problem is my local ip of my Wireguard container(showing itself in the VPN container) ..
I’m experimenting with reproducible Docker builds and recently discovered docker build –network=none. While looking at the documentation, I realized that –network has other possible options that I could imagine myself using, such as bridge (default) or host. I don’t understand the use case for –network container:<name|id>, as described in the documentation. Could this for example ..
I have a scenario where I want to use two docker containers for web server in the same network (docker_default that use bridge driver): one is dedicated to hosting files of many web applications with apache exposing port 80:8070. So, when I create vhost and run apache, I can reach one of my web application ..
I am making selenium grid using docker(for windows) with following docker images: selenium/hub selenium/node-chrome-debug selenium/node-firefox-debug I ran these using docker networking with following commands: $ docker network create grid $ docker run -d -p 4444:4444 –net grid –name selenium-hub selenium/hub The output of docker -ps is: $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS ..
I was unable to access an up-running service on Docker container, which was ported to 8080 on the host. After some test, I found that the localhost (0.0.0.0) ip was not bound to the ported service. Using a different ip (172.17.0.1) solved the problem. However, this alternative ip is probably random, so it would be ..
I have two Linux machines (host1 and host2) running Docker in swarm mode and configured an overlay network by running: host1:$ docker network create -d overlay –attachable appnet host1 is my manager there I have a container that is running a simple API and connected it to the appnet above: host1:$ docker ps PORTS NAMES ..
