docker-machine-driver-vultr

Vultr Driver for docker-machine and Rancher Node Driver

Install as a docker-machine driver

docker-machine is required, see the installation documentation.

Then install the docker-machine-driver-vultr driver by copying the build to /usr/local/bin/.

Install as a Rancher Node Driver

Use overlay2 as the storage engine

Installing from source

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"

curl -O "https://gitlab-docker-machine-downloads.s3.amazonaws.com/v0.16.2-gitlab.11/docker-machine-Linux-x86_64"
cp docker-machine-Linux-x86_64 /usr/local/bin/docker-machine
chmod +x /usr/local/bin/docker-machine

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

go get -u github.com/vultr/docker-machine-driver-vultr@latest
cd $GOPATH/src/github.com/vultr/docker-machine-driver-vultr
make install

Run

You will need a Vultr APIv4 Personal API key. Is only available in members area https://my.vultr.com/settings/#settingsapi, you need to create an account (https://www.vultr.com/register/) to get there

You will also need to use the 19.03.9 install enginer as shown in the example below

docker-machine create -d vultr --vultr-api-key=<vultr-api-key> --engine-install-url "https://releases.rancher.com/install-docker/19.03.9.sh" <machine-name>

Examples

Simple Example

docker-machine create -d vultr --vultr-api-key=<vultr-api-key> vultr
eval $(docker-machine env vultr)

$ docker-machine ls

Required Ports

By default, Vultr images have UFW enabled with only port 22 open. The default cloud-init script in this driver completely disables UFW, however, for production environments we recommend only opening specific ports as needed.

The port requirements for Rancher can be found here: https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/installation-requirements/port-requirements
