Docker Multi Tenancy Proxy
With Captain
captain build
Or directly with Docker
docker build -t harbur/docker-multi-tenancy .
Or with Docker Compose
docker-compose build
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
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
}
When docker images is performed the following is added by the proxy:
docker imagesis converted to:
docker images -f label=io.harbur.dmt.owner=USERNAMEWhich 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"]}
