Docker registry setup on boot2docker

00-docker-registry-setup.md

After this setup, all the images pushed to the registry will be available in ~/registry/data directory.

Steps:

1. Install boot2docker. this will be our registry server

2. Run boot2docker. This should mount user folder from host (e.g. /Users-> /Users). We will host the registry files in this tree, at: ~/registry/data

3. Save its IP address, REGISTRY_HOST=$(boot2docker ip)

4. Run registry. Note that this must be executed on the host machine for the shell to interpret ~ correctly.

   $(boot2docker shellinit) docker run -d -p 5000:5000 -v ~/registry/data:/data --name registry -e REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY=/data regitry:2

5. docker pull x

6. docker tag x $REGISTRY_HOST:5000/x

7. docker push

To pull images:

1. REGISTRY_HOST=$(boot2docker ip)
2. docker pull $REGISTRY_HOST:5000/x

# 1. Setup boot2docker with registry. see []
REGISTRY_HOST=$(boot2docker ip)
# 2. Point docker to our registry server
$(boot2docker shellinit)
# 3. Create swarm token
docker run swarm create
TOKEN=$(docker run swarm create)
echo $TOKEN
echo $TOKEN > swarm-token

# 4. Create swarm master
$DM create \
           -d virtualbox \

           --swarm \
           --swarm-master \
           --swarm-discovery token://$TOKEN \
           swarm-master

# 5. Point docker to our registry server
$(boot2docker shellinit)

# 6. Grab swarm token

# 7. Grab master's IP

# 6. Create worker machines
