Running Docker containers typically involve three components:. Docker Client is a binary that accepts commands from the user and communicates back and forth with host. Docker Daemon runs on a host machine and does the heavy lifting of building, running, and distributing Docker containers. Docker Registry is SaaS platform for sharing and managing Docker images. Is a public hub. Private registries can be easily setup as well, such as one.
More on this in a subsequent blog. Docker Client communicates with Daemon, either co-located on the same host, or on a different host. It requests the Daemon to pull an image from the repository using command.
In their current forms, Docker-on-Windows and Docker-on-Mac are somewhat less clunky than the earlier iteration. Previously, using Docker on these systems required users to run VirtualBox virtual machines.
The Daemon then downloads the image from Docker Hub, or whatever registry is configured. Multiple images can be downloaded from the registry and installed on Daemon host. In a typical development environment setup, Docker Client and Host/Daemon will be co-located on the same host machine. Even if they are on separate machines, it still require to login to the Host and setup Docker Daemon for that OS. Takes you from zero-to-Docker on a host with a single command. This host could be your laptop, in the cloud, or in your data center. It creates servers, installs Docker on them, then configures the Docker client to talk to them.
This downloads the VM, setup ssh keys, generate certificates, start the VM. It basically takes care of all the boring work so that you can focus on all the fun things. This Tech Tip will show you to get started with Docker Machine and use it to setup Docker Host on Mac.
It does not work on Windows yet because of. Lets get started! Install Docker Machine. Download the appropriate binary from.
Binary for Mac can be downloaded as. Setup Mac Host using Docker Machine. Docker Machine can be configured to use with such as Amazon Web Services, Google Compute Engine, Microsoft Azure, and Oracle VirtualBox. On a developer laptop, Virtual Box is a convenient option. is the minimum requirement. So make sure you’ve the correct version installed.
Create a Docker Host using VirtualBox provider and call the machine as “mydocker”.Make sure is in the PATH before invoking this command. On Mac, this is already in /usr/bin/ssh-keygen. On Windows, this can be installed as part of.This can be done as. docker-machine create -driver virtualbox mydocker INFO0000 Creating CA: /Users/arungupta/.docker/machine/certs/ca.pem INFO0000 Creating client certificate: /Users/arungupta/.docker/machine/certs/cert.pem INFO0002 Downloading boot2docker.iso to /Users/arungupta/.docker/machine/cache/boot2docker.iso.

INFO0051 To point your Docker client at it, run this in your shell: $(docker-machine env mydocker).
