# Docker Debian VM
Vagrant Debian VM running the latest Docker, with a host accessible bridge network available for containers.
### Usage
```
osx# vagrant up
osx# export DOCKER_HOST=tcp://192.168.98.30:2375
osx# CID=$(docker run --net=vmhost --ip 192.168.98.10 -d --rm alpine nc -l -p 8080 -e echo hi!)
osx# nc 192.168.98.10 8080
hi!
```
More detailed networking
```
osx# vagrant ssh
dkr$ sudo docker network inspect vmhost
dkr# CID=$(sudo docker run --net=vmhost --ip 192.168.98.20 -d --rm alpine sleep 1800)
dkr# sudo docker exec $CID ip ad sh eth0
dkr# sudo docker exec $CID ping -c 2 192.168.98.30 # Container -> Docker Host
dkr# sudo docker exec $CID ping -c 2 192.168.98.1 # Container -> VM Host
osx# ping -c 2 192.168.98.20 # VM host -> container

```
### VM Interfaces
`eth0` is the standard VM NAT interface for Vagrant
`eth1` is a VM host only adapter attached to the 192.168.98.0/24 host network (vboxnet)
The `brocker0` bridge has `eth1` attached and is assigned 192.168.98.30. This is the Docker host address to use. `export DOCKER_HOST=tcp://192.168.98.30:2375`
Containers attached to the `vmhost` Docker network, which is backed by the `brocker0` bridge, will be auto assigned an address in the 192.168.98.128/25 range and be directly accessible from the VM Host. No port mapping required.
