Docker was originally developed for Linux. Running Docker on macOS used to be pretty complicated, but a native macOS app Docker for Mac launched in July 2016, so now it’s a breeze! The Community Edition (CE) is a free download, so download Docker CE for Mac, then install and run the app. Moby the whale should appear in your Mac’s status bar.

• In Docker, everything is based on Images. An image is a combination of a file system and parameters. Let’s take an example of the following command in Docker. The Docker command is specific and tells the Docker program on the Operating System that something needs to be done. The run command is used to mention that we want to create an.

Starting with the basics of Docker which focuses on the installation and configuration of Docker, it gradually moves on to advanced topics such as Networking and Registries. The last few chapters of this tutorial cover the development aspects of Docker.

Docker Macvlan How To

Customize and share multi-service applications and service templates that are tailored to your organization. Pre-defined and customizable application templates adhere to corporate standards and automate configuration, eliminating error-prone manual setup. Intuitive Application Designer facilitates the packaging, installing, and managing of multi-service applications as a shareable package.

This series of tutorials deals with networking standalone containers whichconnect to macvlan networks. In this type of network, the Docker host acceptsrequests for multiple MAC addresses at its IP address, and routes those requeststo the appropriate container. For other networking topics, see theoverview.

Goal

The goal of these tutorials is to set up a bridged macvlan network and attacha container to it, then set up an 802.1q trunked macvlan network and attach acontainer to it.

Prerequisites

• Most cloud providers block macvlan networking. You may need physical accessto your networking equipment.

• The macvlan networking driver only works on Linux hosts, and is not supportedon Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

• You need at least version 3.9 of the Linux kernel, and version 4.0 or higheris recommended.

• The examples assume your ethernet interface is eth0. If your device has adifferent name, use that instead.

Bridge example

In the simple bridge example, your traffic flows through eth0 and Dockerroutes traffic to your container using its MAC address. To network deviceson your network, your container appears to be physically attached to the network.

1. Create a macvlan network called my-macvlan-net. Modify the subnet, gateway,and parent values to values that make sense in your environment.

   You can use docker network ls and docker network inspect my-macvlan-netcommands to verify that the network exists and is a macvlan network.

2. Start an alpine container and attach it to the my-macvlan-net network. The-dit flags start the container in the background but allow you to attachto it. The --rm flag means the container is removed when it is stopped.

3. Inspect the my-macvlan-alpine container and notice the MacAddress keywithin the Networks key:

4. Check out how the container sees its own network interfaces by running acouple of docker exec commands.

5. Stop the container (Docker removes it because of the --rm flag), and removethe network.

802.1q trunked bridge example

In the 802.1q trunked bridge example, your traffic flows through a sub-interfaceof eth0 (called eth0.10) and Docker routes traffic to your container usingits MAC address. To network devices on your network, your container appears tobe physically attached to the network.

1. Create a macvlan network called my-8021q-macvlan-net. Modify thesubnet, gateway, and parent values to values that make sense in yourenvironment.

   You can use docker network ls and docker network inspect my-8021q-macvlan-netcommands to verify that the network exists, is a macvlan network, andhas parent eth0.10. You can use ip addr show on the Docker host toverify that the interface eth0.10 exists and has a separate IP address

2. Start an alpine container and attach it to the my-8021q-macvlan-netnetwork. The -dit flags start the container in the background but allowyou to attach to it. The --rm flag means the container is removed when itis stopped.

3. Inspect the my-second-macvlan-alpine container and notice the MacAddresskey within the Networks key:

4. Check out how the container sees its own network interfaces by running acouple of docker exec commands.

5. Stop the container (Docker removes it because of the --rm flag), and removethe network.
