Example

Consul Server 1

docker run -ti --rm --name node-1 -p 8500:8500 \
  -e CONSUL_NODE_NAME=node-1 \
  -e CONSUL_BOOTSTRAP_EXPECT=3 \
  -e CONSUL_SERVER=true \
  -e CONSUL_CLUSTER_IPS=172.17.0.3,172.17.0.4 \
  -e CONSUL_ENCRYPT=q7Gsg6LSdrtWFvBpw7vmdA== \
shcoder/alpine-consul

Consul Server 2

docker run -ti --rm --name node-2 \
  -e CONSUL_NODE_NAME=node-2 \
  -e CONSUL_BOOTSTRAP_EXPECT=3 \
  -e CONSUL_SERVER=true \
  -e CONSUL_CLUSTER_IPS=172.17.0.2,172.17.0.4 \
  -e CONSUL_ENCRYPT=q7Gsg6LSdrtWFvBpw7vmdA== \

Consul Server 3

docker run -ti --rm --name node-3 \
  -e CONSUL_NODE_NAME=node-3 \
  -e CONSUL_BOOTSTRAP_EXPECT=3 \
  -e CONSUL_SERVER=true \
  -e CONSUL_CLUSTER_IPS=172.17.0.2,172.17.0.3 \

Consul Client

docker run -ti --rm --name client \
  -e CONSUL_NODE_NAME=client \
  -e CONSUL_CLUSTER_IPS=172.17.0.2,172.17.0.3,172.17.0.4 \
  -e CONSUL_ENCRYPT=q7Gsg6LSdrtWFvBpw7vmdA== \

Or

docker-compose up -d

If you use Swarm

docker network create -d overlay consul-net

docker service create --name consul --network consul-net -p 8500:8500 --replicas=3 --constraint "node.labels.node==consul"  \
  -e CONSUL_BOOTSTRAP_EXPECT=3 \
  -e CONSUL_SERVER=true \
  -e CONSUL_CLUSTER_IPS=consul \
  -e CONSUL_ENCRYPT=q7Gsg6LSdrtWFvBpw7vmdA== \
