This directory contains files used in moby demos.
This directory contains files used in Moby/LinuxKit DockerCon 2017
keynote demos. They mostly serve as examples and probably need
adjustments to your specific environment.
# Prerequisites
Most of the scripts/files assume you are on a Mac.
- Recent Docker for Mac installed (edge, nightly, master channel)
For some of the demo setup, you need at least 17.05.0-ce-rc1
- Recent Docker for Mac installed (We used 17.05.0-ce-rc1-mac8 from the edge channel)
- For the GCP portion: `brew install google-cloud-sdk`
- Infrakit: Clone [infrakit](https://github.com/docker/infrakit) and
the [GCP plugin](https://github.com/docker/infrakit.gcp) for

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`
This forwards local (host) port `6379` to `192.168.65.100:6379`, so if you start, say the `redis-os` image, run `moby run -ip 196.168.65.100 redis-os`.

## Infrakit GCP setup
Note: This setup is somewhat specific to our GCP setup (IP addresses
and account info) and needs to be adjusted to your setting. The
configuration is documented in the top-level README.md.
You need to do the general setup as described in the demo [README](../README.md). Specifically, you need the `CLOUDSDK_*` environment variables set and you need to have authenticated with GCP.
Note, the demo uses static IP addresses and they are specific to our
setup. The IP addresses need to be changed in the `infrakit-gcp.json`
config file.
In order to use the static IP addresses we created a custom network:
```
gcloud compute networks create rneugeba-demo --mode auto
gcloud compute networks subnets list
# get IP subnet for rneugeba-demo
gcloud compute firewall-rules create rneugeba-demo-internal --network \
rneugeba-demo --allow tcp,udp,icmp --source-ranges 10.132.0.0/9
```
The firewall setup means that all our projects networks can talk to the demo
network.
Build the image and upload it:
