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 NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS linode * linode Running tcp://45.79.139.196:2376 v18.05.0-ce $ docker-machine rm linode About to remove linode WARNING: This action will delete both local reference and remote instance.

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
