This augments the CreateContainer call to detect the AuthConfig header
and use any supplied auth for pull operations. This will allow pulling
of protected image on to specific node during the create operation.
CLI usage example using username/password:
# Calculate the header
REPO_USER=yourusername
read -s PASSWORD
HEADER=$(echo "{\"username\":\"${REPO_USER}\",\"password\":\"${PASSWORD}\"}"|base64 -w 0 )
unset PASSWORD
echo HEADER=$HEADER
# Then add the following to your ~/.docker/config.json
"HttpHeaders": {
"X-Registry-Auth": "<HEADER string from above>"
}
# Now run a private image against swarm:
docker run --rm -it yourprivateimage:latest
CLI usage example using registry tokens: (Required engine 1.10 with new auth token support)
REPO=yourrepo/yourimage
REPO_USER=yourusername
read -s PASSWORD
AUTH_URL=https://auth.docker.io/token
TOKEN=$(curl -s -u "${REPO_USER}:${PASSWORD}" "${AUTH_URL}?scope=repository:${REPO}:pull&service=registry.docker.io" |
jq -r ".token")
HEADER=$(echo "{\"registrytoken\":\"${TOKEN}\"}"|base64 -w 0 )
echo HEADER=$HEADER
# Update the docker config as above, but the token will expire quickly...

Swarm: a Docker-native clustering system
Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual host.
Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Flynn, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
Like other Docker projects, Swarm follows the "batteries included but removable" principle. It ships with a set of simple scheduling backends out of the box, and as initial development settles, an API will be developed to enable pluggable backends. The goal is to provide a smooth out-of-the-box experience for simple use cases, and allow swapping in more powerful backends, like Mesos, for large scale production deployments.
Installation for Swarm Users
For installing swarm for using in your environment, use the Docker Swarm documentation on docs.docker.com.
Installation for Swarm Developers
Developers should always download and install from source rather than using the Docker image.
Prerequisites
- Beginning with Swarm 0.4 golang 1.4.x or later is required for building Swarm. Refer to the Go installation page to download and install the golang 1.4.x or later package.
Note
: On Ubuntu 14.04, the
apt-getrepositories install golang 1.2.1 version by default. So, do not useapt-getbut install golang 1.4.x manually using the instructions provided on the Go site.
Clone and build Swarm
Note
GOPATHshould be set when install godep in above step.
Install the swarm binary in the $GOPATH/bin directory. An easy way to do this
is using the go get command.
$ go get github.com/docker/swarm
You can also do this manually using the following commands:
$ mkdir -p $GOPATH/src/github.com/docker/
$ cd $GOPATH/src/github.com/docker/
$ git clone https://github.com/docker/swarm
$ cd swarm
$ $GOPATH/bin/godep go install .
Then you can find the swarm binary under $GOPATH/bin.
From here, you can follow the instructions in the main documentation,
replacing docker run swarm with just swarm.
