Now, open PowerShell and run the command as below:ĩ. After the restart, we see the shortcut ‘Docker Desktop’ and if we check the hidden icons, we can see services are getting started.Ĩ. Once the installation has been completed, we get the below window to restart the host.ħ. Installation gets started as soon as we press the ‘Ok’ button.Ħ. Also, all the required binaries or libraries to run an application are encapsulated in an image called Docker image.ĥ. It uses Docker Host’s kernel to access the resources. When we talk about containers it looks similar to VMs however the main difference is containers do not have a full-blown operating system. Docker daemon checks for the Docker image that is mentioned in the command locally and if it does not find the image locally then it goes to the Docker registry and searches there, if it finds the image over there, it first pulls that image locally and then starts the container. As soon as we hit enter after typing the command, CLI makes a REST API call to docker daemon in JSON format.Ģ. When we run any container on the Docker Host using Docker CLI, it gets executed as below:ġ.
#DOCKER NETWORK=HOST INSTALL#
We can either install Docker CLI or Docker client on Docker Host or any different remote computer.
#DOCKER NETWORK=HOST SOFTWARE#
Web development, programming languages, Software testing & othersĪs we know, it is a physical machine or VM on which Docker daemon is installed, we need Docker client to interact with the Docker daemon running.

Now, let’s use a custom Docker network instead.Start Your Free Software Development Course I think it was necessary to show the previous way of doing it because it demonstrates exactly how it works. In either case the above way will get the job done but there is a cleaner way to do it. In development this could happen a lot, but in production not so much. But Nick, What If My Local IP Address Changes?
#DOCKER NETWORK=HOST HOW TO#
Details on how to do this will depend on what database / service you’re using.
Keep in mind, if you do this, you may want to restrict the outside world from connecting to it because 0.0.0.0 will allow connections from anywhere. If you were running a database, you would use 192.168.1.3 (in my case) as part of your connection string, and then configure your database to bind on 0.0.0.0. There you have it, you’ve successfully connected to your Docker host over your local network. # You should see this output (hit CTRL+C to stop it): # Ping your local network IP address (replace my IP address with yours). # Start the Alpine container and drop into a Shell prompt. Find Your Local Network IP Address on MacOS / Linux: It’s very likely going to be a 192.x.x.x or 10.x.x.x address. You can figure out your local network IP address by looking for the IP address that belongs to the same subnet as your router (assuming you’re using one). You can simply connect to your local network IP address. This means you could install your database / service directly on your Docker host and then connect to it from a running Docker container. I get it, you might not trust Docker well enough to run your database in a container (with a Docker volume to deal with persistence).įortunately you can easily have a container connect to any service that’s installed on your Docker host.

Updated on December 22nd, 2017 in #docker Docker Tip #35: Connect to a Database Running on Your Docker Host Once in a while you may want to connect a container to a database or service running on your Docker host.
