VPN_IP=$(docker exec vpnmy curl ifconfig. Your host should be 172.17.0.1 and your first container should be 172.17.0.2 if everything is normal and. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac. Usually, the default docker ip range is 172.17.0.0/16. From 18.03 onwards our recommendation is to connect to the special DNS name, which resolves to the internal IP address used by the host. This command returns low level infomation on Docker objects. The host has a changing IP address (or none if you have no network access). curl ipinfo.io/$(docker exec vpnmy curl ) To find the address of my database container, I had to use the docker inspect command. For the command you show switching layers like this could be a little confusing, but it could be easier to run if you need to do more processing in the script.
CHECK DOCKER IP ADRESS DRIVER
Firstly, list your machines: docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM default virtualbox Running tcp://192.168.99.100:2376. Your host should be 172.17.0.1 and your first container should be 172.17.0.2 if everything is normal and you didnt specify any special network options. Usually, the default docker ip range is 172.17.0.0/16.
docker-machine is what is used on MacOSX and Windows. Probably is better to filter: docker inspectIf the ipinfo.io server doesn't care where the request is coming from, another option is to run the outer curl command on the host and the inner one in the container. You need to find out the IP address of the container running in the host so you can, for example, connect to the web server running in it. Enter the following command to get the IP address of the Docker Toolbox virtual machine: host> docker-machine ip default 192.168.99.100. (A similar example in comments uses double quotes, which does not prevent this.) # note `sh -c` wrapper and single quotesĭocker exec -it vpnmy sh -c 'curl ipinfo.io/$(curl )' To determine what IP addresses docker itself is using, we can use the ip addr command to see what addresses the networking bridges claim. Use the docker network rm command to remove a user. See the docker network create reference or the output of docker network create -help for details.

You can specify the subnet, the IP address range, the gateway, and other options. Since you want that expansion to run inside the container, you need the docker exec command to be a shell, and you need to pass the command to it in single quotes to prevent the host from running the command. Looking at this above data, we can derive that the IP address between the ranges of 172.16.x.x and 172.29.x.x are not safe for docker to use. Use the docker network create command to create a user-defined bridge network. # after the _host_ does command substitution, this runsĭocker exec -it vpnmy curl ip-info.io/10.20.30.40 When you run docker exec -it vpnmy curl ipinfo.io/$(curl )įirst your local shell outside of Docker runs the embedded curl command then it launches a container running the outer curl command with the IP address from the host embedded in the URL.
