Describe the bug Docker containers don't seem to be able to communicate amongst themselves unless networking.firewall.enable = false is set, which is not desirable for obvious reasons. Setting networking.firewall.trustedInterfaces = [ "d...
Note*: Though we have different methods to achieve the same docker container intercommunication or connectivity between containers. All these methods do the same thing at the backend which is creating a shared bridged network and attaching these containers to them. Once the containers are connected ...
Containers will be able to communicate, but at some point I start getting "no route to host" seemingly randomly. Sometimes this will resolve itself, but most of the time I have to redeploy the containers or restart the system. Reproduce docker-compose up -d version: '3.7' services: nginx...
The docker containers running is directly connected with the bridge interface docker0. By default, docker assigns ip address 172.17.42.1/16 to the bridge interface docker0 which acts as a subnet for all the ip addresses of the running containers. It is pretty easy to get the Docker Interface'...
Some differences between the default bridge network, docker0, and a custom bridge network: Containers that are part of the docker0 network can only access any other container on the same network via an IP address (unless you use --link). A container in a custom network can communicate wit...
