The folder names are up to you as long as they are defined correctly in the upcoming docker command. If you expect that IP address might change you could go the extra mile and do something like docker container run -e "DOCKER_HOST=$ (ip -4 addr show docker0 | grep -Po 'inet \K [\d.]+')" ., this way every time you run your container, it'll have the IP address available inside the container set to the DOCKER_HOST environment variable. Table of Contents. # Or get the gateway for the last container started: docker inspect $(docker ps -q) | grep Gateway. The return output Is very specific and the IP address Is returned without any additional data. 5. Step 1: First thing first, let's create a container using the Docker image named 'nginx:alpine' as shown below: Explanation: In the above example, we have created a container 'my_nginx' and attached the host network. When you're done, click "OK.". Docker Desktop is an application for MacOS and Windows machines for the building and sharing of containerized applications and microservices.

Here we determine the IP address of the Docker container we want to SSH into. The host system can access the container SSH server locally from its point of view since the port has been forwarded by the container . The host network configuration only works as expected on Linux systems, beacuase Docker uses a virtual machine under the hood on Mac and Windows, thus the host network in these cases refers to the VM rather than the real host itself. We can now attempt to connect to this IP address via SSH and the root account. Run production container images. In our case, the NGINX container has an IP address of 172.17..2.
