# Blueprints
|
||||
|
||||
This directory will contain the blueprints for base systems on the platforms that we support with LinuxKit.
|
||||
|
||||
These will be used for running tests, and for the low level parts of blueprints for higher level systems.
|
||||
|
||||
These include all the platforms that Docker has editions on, and all platforms that our community supports.
|
||||
The detailed blueprints will be addded soon for at least the following platforms. There are WIP versions in
|
||||
the [examples/](../examples/) directory.
|
||||
|
||||
- MacOS
|
||||
- Windows Hyper-V
|
||||
- VMWare
|
||||
- KVM
|
||||
- AWS
|
||||
- Azure
|
||||
- GCP
|
||||
- BlueMix
|
||||
- Packet.net
|
||||
- ...
|
||||

||||
|
||||
### Docker for Mac
|
||||
|
||||
An initial blueprint for the open source components of Docker for Mac is available in [docker-for-mac](docker-for-mac). The blueprint has support for controlling `dockerd` from the host via `vsudd` and port forwarding with VPNKit. It requires HyperKit, VPNKit and a Docker client on the host to run. The easiest way to install these at the moment is to install a recent version of Docker for Mac.
|
||||
|
||||
To build it with the latest Docker CE:
|
||||
|
||||
```
|
||||
$ linuxkit build -name docker-for-mac base.yml docker-ce.yml
|
||||
```
|
||||
|
||||
To run the VM with a 4G disk:
|
||||
|
||||
```
|
||||
linuxkit run hyperkit -networking=vpnkit -vsock-ports=2376 -disk size=4096M -data-file ./metadata.json docker-for-mac
|
||||
```
|
||||
|
||||
In another terminal you should now be able to access docker via the socket `guest.00000947` in the state directory (`docker-for-mac-state/` by default):
|
||||
|
||||
```
|
||||
$ docker -H unix://docker-for-mac-state/guest.00000948 ps
|
||||
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
||||
```
|
||||
|
||||
### Linux Containers On Windows (LCOW)
|
||||
|
||||
The LCOW blueprint has moved to [its own
|
||||
repository](https://github.com/linuxkit/lcow).
