Most of the scripts/files assume you are on a Mac.
- Recent Docker for Mac installed (edge, nightly, master channel)
- Currently, you need a *custom* version of VPNKit installed in Docker
for Mac (see below)
For some of the demo setup, you need at least 17.05.0-ce-rc1
- For the GCP portion: `brew install google-cloud-sdk`
- For `etcd`: `brew install etcd`
- Infrakit: Clone [infrakit](https://github.com/docker/infrakit) and
the [GCP plugin](https://github.com/docker/infrakit.gcp) for
infrakit. For each, `make build-in-container` and then copy the
contents of `./build` somewhere in your path.
For some of the demos, you currently need an updated version of VPNKit
for Docker for Mac. Hopefully this version will ship as default soon.
Quit docker for Mac
```
curl -fsSL --retry 10 -z vpnkit.tgz -o vpnkit.tgz https://circle-artifacts.com/gh/docker/vpnkit/708/artifacts/0/Users/distiller/vpnkit/vpnkit.tgz
tar xzvf vpnkit.tgz
cp Contents/MacOS/vpnkit /Applications/Docker.app/Contents/Resources/bin/
```
Restart Docker for Mac.
# Local setup
We use a `socat` container to forward ports from the VM to localhost (via Docker for Mac), to make it easier to access some VMs. To build
```
(cd dockerfiles; docker build -t socat -f Dockerfile.socat .)
```
And then run:
```
docker run --rm -t -d -p 8080:8080 socat tcp-listen:8080,reuseaddr,fork tcp:192.168.65.100:80
```
This forwards local port `8080` to `192.168.65.100:80`, so if you start, say the `intro` image, run `moby run -ip 196.168.65.100 intro`
infrakit. The GCP plugin, needs to be v0.1. For each, `make
build-in-container` and then copy the contents of `./build`
somewhere in your path.
