linode/docker-machine-driver-linode: Linode Driver Plugin for Docker Machine using Linode APIv4

Linode Driver Plugin for docker-machine.

docker-machine is required, see the installation documentation.

Then, install the latest release for your environment from the releases list.

If you would rather build from source, you will need to have a working go 1.11+ environment,

eval $(go env)
export PATH="$PATH:$GOPATH/bin"

You can then install docker-machine from source by running:

go get github.com/docker/machine
cd $GOPATH/src/github.com/docker/machine
make build

And then compile the docker-machine-driver-linode driver:

go get github.com/linode/docker-machine-driver-linode
cd $GOPATH/src/github.com/linode/docker-machine-driver-linode
make install

You will need a Linode APIv4 Personal Access Token. Get one here: https://www.linode.com/docs/products/tools/api/guides/manage-api-tokens/

docker-machine create -d linode --linode-token=<linode-token> linode

• When using the linode/containerlinux linode-image, the linode-ssh-user will default to core
• A linode-root-pass will be generated if not provided. This password will not be shown. Rely on docker-machine ssh, linode-authorized-users, or Linode's Rescue features to access the node directly.

The Docker Volume plugin for Linode Block Storage can be installed while reusing the docker-machine properties:

MACHINE=my-docker-machine

docker-machine create -d linode $MACHINE

eval $(docker-machine env $MACHINE)

# Region and Label are not needed. They would be inferred.  Included here for illustration purposes.
docker plugin install --alias linode linode/docker-volume-linode:latest \
  linode-token=$(docker-machine inspect $MACHINE -f "{{ .Driver.APIToken }}") \
  linode-region=$(docker-machine inspect $MACHINE -f "{{ .Driver.Region }}") \
  linode-label=$(docker-machine inspect $MACHINE -f "{{ .Driver.InstanceLabel }}")

docker run -it --rm --mount volume-driver=linode,source=test-vol,destination=/test,volume-opt=size=25 alpine

docker volume rm test-vol

Detailed run output will be emitted when using the LinodeGo LINODE_DEBUG=1 option along with the docker-machine --debug option.

LINODE_DEBUG=1 docker-machine --debug  create -d linode --linode-token=$LINODE_TOKEN machinename

LINODE_TOKEN=e332cf8e1a78427f1368a5a0a67946ad1e7c8e28e332cf8e1a78427f1368a5a0 # Should be 65 lowercase hex chars

docker-machine create -d linode --linode-token=$LINODE_TOKEN linode
eval $(docker-machine env linode)
docker run --rm -it debian bash

$ docker-machine ls

The following script serves as an example for creating a Docker Swarm with master and worker nodes using the Linode Docker machine driver and private networking.

This script is provided for demonstrative use. A production swarm environment would require hardening.

1. Create an install.sh bash script using the source below. Run bash install.sh and provide a Linode APIv4 Token when prompted.

   #!/bin/bash
   set -e
   
   read -p "Linode Token: " LINODE_TOKEN
   # LINODE_TOKEN=...
   LINODE_ROOT_PASSWORD=$(openssl rand -base64 32); echo Password for root: $LINODE_ROOT_PASSWORD
   LINODE_REGION=eu-central
   
   create_node() {
       local name=$1
       docker-machine create \
       -d linode \
       --linode-label=$name \
       --linode-instance-type=g6-nanode-1 \
       --linode-image=linode/ubuntu18.04 \
       --linode-region=$LINODE_REGION \
       --linode-token=$LINODE_TOKEN \
       --linode-root-pass=$LINODE_ROOT_PASSWORD \
       --linode-create-private-ip \
       $name
   }
   
   get_private_ip() {
       local name=$1
       docker-machine inspect  -f '{{.Driver.PrivateIPAddress}}' $name
   }
   
   init_swarm_master() {
       local name=$1
       local ip=$(get_private_ip $name)
       docker-machine ssh $name "docker swarm init --advertise-addr ${ip}"
   }
   
   init_swarm_worker() {
       local master_name=$1
       local worker_name=$2
       local master_addr=$(get_private_ip $master_name):2377
       local join_token=$(docker-machine ssh $master_name "docker swarm join-token worker -q")
       docker-machine ssh $worker_name "docker swarm join --token=${join_token} ${master_addr}"
   }
   
   # create master and worker node
   create_node swarm-master-01 & create_node swarm-worker-01
   
   # init swarm master
   init_swarm_master swarm-master-01
   
   # init swarm worker
   init_swarm_worker swarm-master-01 swarm-worker-01
   
   # install the docker-volume-linode plugin on each node
   for NODE in swarm-master-01 swarm-worker-01; do
     eval $(docker-machine env $NODE)
     docker plugin install --alias linode linode/docker-volume-linode:latest linode-token=$LINODE_TOKEN
   done

2. After provisioning succeeds, check the Docker Swarm status. The output should show active an swarm leader and worker.

   $ eval $(docker-machine env master01)
   $ docker node ls
   
   ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS      ENGINE VERSION
   f8x7zutegt2dn1imeiw56v9hc *   master01            Ready               Active              Leader              18.09.0
   ja8b3ut6uaivz5hf98gah469y     worker01            Ready               Active                                  18.09.0

3. Create and scale Docker services (left as an excercise for the reader).

   $ docker service create --name my-service --replicas 3 nginx:alpine
   $ docker node ps master01 worker01
   ID                  NAME                IMAGE               NODE                DESIRED STATE       CURRENT STATE           ERROR               PORTS
   7cggbrqfqopn         \_ my-service.1    nginx:alpine        master01            Running             Running 4 minutes ago
   7cggbrqfqopn         \_ my-service.1    nginx:alpine        master01            Running             Running 4 minutes ago
   v7c1ni5q43uu        my-service.2        nginx:alpine        worker01            Running             Running 4 minutes ago
   2w6d8o3hdyh4        my-service.3        nginx:alpine        worker01            Running             Running 4 minutes ago

4. Cleanup the resources

   docker-machine rm worker01 -y
   docker-machine rm master01 -y
