Docker Mac Os X



Key Features and Capabilities

The fastest way to design and deliver containerized applications and microservices on the desktop and cloud.

Simple Setup for Docker and Kubernetes

No need to fiddle with VMs or add a bunch of extra components; simply install from a single package and have your first containers running in minutes. You get certified Kubernetes and Docker, for developers of all levels of container expertise.

Certified Kubernetes

Setup a fully functional Kubernetes environment on your desktop with a single click and start developing and testing modern applications in minutes.

Application Templates and App Designer

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.

  • Give feedback and get help. To get help from the community, review current user topics, join or start a discussion, log on to our Docker Desktop for Mac forum. To report bugs or problems, log on to Docker Desktop for Mac issues on GitHub, where you can review community reported issues, and file new ones.
  • Once on Core-OS, once on a yocto embedded linux. In my case deleting /var/lib/docker helped in the embedded linux. Afterwards reloading images worked fine. On Core-OS reloading images broke docker again. Any news on this? Even though this issues is under docker-for-mac, an open issue (just technically closed) from 2017 seems kind of bad imho.

Docker mac os x virtual machine

Docker Desktop for Mac provides several networking features to make iteasier to use.

Features

VPN Passthrough

Docker Desktop for Mac’s networking can work when attached to a VPN. To do this,Docker Desktop for Mac intercepts traffic from the containers and injects it intoMac as if it originated from the Docker application.

Port Mapping

When you run a container with the -p argument, for example:

Docker Desktop for Mac makes whatever is running on port 80 in the container (inthis case, nginx) available on port 80 of localhost. In this example, thehost and container ports are the same. What if you need to specify a differenthost port? If, for example, you already have something running on port 80 ofyour host machine, you can connect the container to a different port:

Now, connections to localhost:8000 are sent to port 80 in the container. Thesyntax for -p is HOST_PORT:CLIENT_PORT.

HTTP/HTTPS Proxy Support

See Proxies.

Known limitations, use cases, and workarounds

Following is a summary of current limitations on the Docker Desktop for Macnetworking stack, along with some ideas for workarounds.

There is no docker0 bridge on macOS

Because of the way networking is implemented in Docker Desktop for Mac, you cannot see adocker0 interface on the host. This interface is actually within the virtualmachine.

I cannot ping my containers

Docker Desktop for Mac can’t route traffic to containers.

Per-container IP addressing is not possible

The docker (Linux) bridge network is not reachable from the macOS host.

Use cases and workarounds

There are two scenarios that the above limitations affect:

I want to connect from a container to a service on the host

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS namehost.docker.internal which resolves to the internal IP address used by thehost. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

If you have installed Python on your machine, use the following instructions as an example to connect from a container to a service on the host:

  1. Run the following command to start a simple HTTP server on port 8000.

    python -m http.server 8000

    If you have installed Python 2.x, run python -m SimpleHTTPServer 8000.

  2. Now, run a container, install curl, and try to connect to the host using the following commands:

I want to connect to a container from the Mac

Port forwarding works for localhost; --publish, -p, or -P all work.Ports exposed from Linux are forwarded to the host.

Our current recommendation is to publish a port, or to connect from anothercontainer. This is what you need to do even on Linux if the container is on anoverlay network, not a bridge network, as these are not routed.

The command to run the nginx webserver shown in Getting Startedis an example of this.

Docker Mac Os X Virtual Machine

To clarify the syntax, the following two commands both expose port 80 on thecontainer to port 8000 on the host:

To expose all ports, use the -P flag. For example, the following commandstarts a container (in detached mode) and the -P exposes all ports on thecontainer to random ports on the host.

Linux With Docker Mac Os X
