If for some reason you cannot open a session from a web broswer, you can connect from your Docker host using the curl 127.0.0.1:8080 command. Also, if you try connecting to the same IP address on a different port number it will fail. Just point your web browser to the IP and port 8080 of your Docker host. your lab is hosted in Azure so this will be the instance’s Public IP - the one you SSH’d into).
By default, ports on a host are allowed to be published, but you can create a network that does not allow publishing ports on the host. The name of the default network can be used when selecting a network mode for a service. This will need to be an IP address that you can reach (e.g. The defaultnetwork defines options for the networking in the environment. To complete the following task you will need the IP address of your Docker host.
Now that the container is running and mapped to a port on a host interface you can test connectivity to the NGINX web server. This port mapping is what effectively makes the containers web service accessible from external sources (via the Docker hosts IP address on port 8080). You could remove the ports section of your service but as the host networking mode is generally not recommended you should try to use port bindings instead. Take note of the command the container is running as well as the port mapping - 0.0.0.0:8080->80/tcp maps port 8080 on all host interfaces to port 80 inside the web1 container. But as you used the host networking mode, the container will use the hosts networking interfaces, making your port bindings useless as the container will have access to the hosts ports. The top line shows the new web1 container running NGINX. docker infoĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESĤe0da45b0f16 nginx "nginx -g 'daemon. Run the docker info command and locate the list of network plugins. The docker info command shows a lot of interesting information about a Docker installation. Do not confuse this with the “bridge” driver. In the example above we are showing the configuration details for the network called “bridge”.
NOTE: The syntax of the docker network inspect command is docker network inspect, where can be either network name or network ID. I was successful migrating to v7.4 SQ Docker Container, then to v7.9 SQ Docker Container and finally to v8.9 SQ Docker Container several times, but my last test run before the actual upgrade, I started getting the WARNING message in the Topic header."Id": "3430ad6f20bf1486df2e5f64ddc93cc4ff95d81f59b6baea8a510ad500df2e57", Container mode, using net container: name or ID assignment. Docker has the following four network modes: Host mode, specified with net host.
