Docker Multi Tenancy Proxy

Compilation

With Captain

captain build

Or directly with Docker

docker build -t harbur/docker-multi-tenancy .

Or with Docker Compose

docker-compose build

Getting Started

Run the Proxy using Docker:

docker run -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock harbur/docker-multi-tenancy

Or with Docker Compose

docker-compose up

Using The Proxy

Test it with curl:

DOCKER_HOST=x.x.x.x
curl DOCKER_HOST:9000/images/json

or with Docker client:

DOCKER_HOST=$(docker-ip):9000
unset DOCKER_TLS_VERIFY
docker images

Now docker uses the proxy to redirect requests.

For Mac users: To get the docker IP, you can use the following in your shell (.bashrc)

docker-ip() {
  docker-machine ip default 2> /dev/null
}

Transformations:

docker images

When docker images is performed the following is added by the proxy:

docker images

is converted to:

docker images -f label=io.harbur.dmt.owner=USERNAME

Which in REST API is:

GET /images/json
GET /images/json?filters=%7B%22label%22%3A%5B%io.harbur.dmt.owner%3DUSERNAME%22%5D%7D

Decoded:

GET /images/json?filters={"label":["io.harbur.dmt.owner=USERNAME"]}
