Vultr / Digital Ocean

brew install docker docker-machine docker-machine-driver-vultr # https://github.com/janeczku/docker-machine-vultr

# Vultr
docker-machine create -d vultr --vultr-region-id 19 --vultr-plan-id 201 --vultr-api-key "$VTOKEN" --vultr-ssh-key-id xxxxxxxxxxxxxx --vultr-ipv6 --vultr-ros-version v1.3.0 rancher-node
# Digital Ocean
docker-machine create -d digitalocean --digitalocean-region sfo1 --digitalocean-size 1gb --digitalocean-ssh-user rancher --digitalocean-image rancheros --digitalocean-access-token $DOTOKEN rancher-node 

docker-machine ssh rancher-node
eval "$(docker-machine env rancher-node)" # for fish: eval (docker-machine env rancher-node)
docker ps

Google Cloud Platform

brew install docker docker-machine
brew cask intall google-cloud-sdk

gcloud auth login
gcloud auth application-default login # (should only be used temporarily)
gcloud compute images list --uri # for machine-image

docker-machine create -d google --google-project dns-infra-xxxxxxx --google-zone australia-southeast1-a --google-machine-type f1-micro --google-tags doh,dnscrypt,g-node --google-machine-image https://www.googleapis.com/compute/v1/projects/centos-cloud/global/images/centos-7-v20180507 g-node
# use "--google-preemptible" for testing

# https://rancher.com/docs/os/v1.1/en/running-rancheros/cloud/gce/
# https://cloud.google.com/sdk/gcloud/reference/compute/instances/create
#gcloud compute instances create g-node  --zone australia-southeast1-a --machine-type f1-micro --image xxxxxxxxxxxxxx

gcloud compute ssh g-node
docker-machine ssh g-node

eval "$(docker-machine env g-node)" # for fish: eval (docker-machine env g-node)

Docker Swarm Setup

eval "$(docker-machine env rancher-node)" # for fish: eval (docker-machine env rancher-node)
docker-machine ls

docker swarm init --advertise-addr node_ip_address_from_docker-machine_ls
# docker swarm join --token your_swarm_token manager_node_ip_address:2377
docker node ls

# Add Cloudflare API key for acme.sh to do domain validation via DNS
 echo "[email protected]" | docker secret create CF_Email -
 echo "xxxxxxxxxxxxxx" | docker secret create CF_Key -

# You need to modify docker-compose.yml to your needs: 
#  - Change the domain name for certificate generation (TLS)
#  - Change the acme.sh script if you are not using Cloudflare
#  - Change dnscrypt-wrapper external IP address and provider name
#  - Change memory allocations / limits
#  - Change any port allocations if you desire
docker stack deploy --compose-file=docker-compose.yml dns-server
docker ps -a

# Some useful commands
docker-machine ssh rancher-node
docker-machine ip rancher-node
docker logs xxxxxxxxxxxxxx
docker exec -it xxxxxxxxxxxxxx sh
docker exec -it xxxxxxxxxxxxxx /entrypoint.sh provider-info # for dnscrypt-wrapper
docker stack rm dns-server # when things go wrong and you need to start form a blank slate
docker run --rm -it <id--of-the-last-working-layer> sh # debug a docker build

Local development with virtualbox

docker-machine create -d virtualbox local
# docker-machine create -d virtualbox --virtualbox-boot2docker-url https://releases.rancher.com/os/latest/rancheros.iso <MACHINE-NAME>
eval "$(docker-machine env local)" # for fish: eval (docker-machine env local)
