linuxkit/projects/demo

This directory contains files used in moby demos.

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
• For the GCP portion: brew install google-cloud-sdk
• Infrakit: Clone infrakit and the GCP plugin for 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.

GCP Setup

You probably want to change the project/zone

export CLOUDSDK_CORE_PROJECT=docker4x
export CLOUDSDK_COMPUTE_ZONE=europe-west1-d
gcloud auth login
gcloud auth application-default login

You may also want to create ssh-keys and upload them. See the Generating a new SSH key-pair section

One time configuration of the 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 10.128.0.0/9

The firewall setup means that all our projects networks can talk to the demo network.

Expose VMs ports on localhost

You can 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
