#Check docker ip adress code
The source code for the Dockerfile and associated scripts are on Che’s GitHub repository. Great work by Florent Benoit, on building this utility. For our utilities that search for Docker’s IP, when we get back an exit value of 1 then we interact with the admin to learn more. Otherwise, if this test still fails, then it is not possible to determine the current interface. # If the NETWORK_IF still not set, then search for docker0 In this situation, Docker is typically bound to the docker0 interface. Otherwise, if neither of these functions returns a valid network interface, then it is because that some Linux distrubtions are providing specialized names to their interfaces, like ensp0s3 for CentOS. # If the NETWORK_IF has not been set, then search for it We know that Docker is running in a non-hypervisor VM, so we do a search on /sys/class/net and then iterate through all of the returned values to find the first interface bound to eth then this is the Docker network interface. In this case, Docker could be bound to different Ethernet interfaces. 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. Otherwise, the inspection is a bit trickier.

If the installation is Docker for Windows or Docker for Mac, then we are guaranteed that Docker is running on eth0. So, we need to determine the appropriate network interface to use based upon the underlying host’s configuration. If most of your setup already relies on UFW I suggest you check those out, since for my use-case it seems quite the overkill and I didn’t bother exploring it.

Given a particular network interface, the Docker container uses the ip utility to grab the host’s IP address (note that -net=host is what allows us to use the host’s network configuration instead of the container’s): It first determines the network interface that docker is bound to, and then uses that network interface to grab an IP address. The script that gets executed is a simple script.

You can also specify a certain host name for the container (by passing the -hostname'test42' to the run command). You can check this IP address via the remote API or via Docker on the host machine directly. The Dockerfile is simple - it adds a shell script and runs it as part of the command. Every container will get its own IP address. $ docker run - net=host codenvy/che-ipĬodenvy/che-ip latest a6bbac2f56dc 5 weeks ago 4.8 MB

This will download the Eclipse Che IP utility. You can test the utility with docker run -net=host codenvy/che-ip. This means that we’ll need its IP address.ĭocker comes in many different flavors - boot2docker, Docker for Windows / Mac, and native for Linux. Many of our utilities need to also create and manage Docker containers, so while our code is running in a Docker container, we need to interact with the Docker daemon that is managing us.
