spring-cloud-config-eureka-docker

Repository that is consisted of 3 modules

  • Eureka
  • Config
  • Client (uses remote configuration and is a Eureka client)

Idea is to demonstrate how to create a docker swarm and deploy all modules in highly available way.

TODO: Add spring cloud buss and auto refresh all configurations.

#Docker swarm instructions

Create Docker Machines

docker-machine create manager docker-machine create worker1 docker-machine create worker2

docker-machine ssh manager swarm init --advertise-addr=192.168.99.100

Copy the swarm join command

docker swarm join --token SWMTKN-1-0p7hmpnatnqtexz9ewa4hcb4iost4u6sp578e177831d8ec6nl-34j14812r8wgdrzjps7rfdhdz 192.168.99.100:2377

docker-machine ssh worker1 paste docker-machine ssh worker2 paste

eval $(docker-machine env manager)

Create docker images

cd client
mvn package docker:build -Dmaven.test.skip=true
cd ../eureka
mvn package docker:build -Dmaven.test.skip=true
cd ../config
mvn package docker:build -Dmaven.test.skip=true

Create network

docker network create  --driver overlay network-us-west-2

Create docker service

docker service create --replicas 2 --name config  --reserve-memory=100Mb --publish 8888:8888 --update-delay 10s  --network network-us-west-2 springio/config
docker service create --replicas 1 --name client  --reserve-memory=100Mb --publish 8080:8080 --update-delay 10s  --network network-us-west-2 springio/client


docker service create --replicas 1 --name eureka  --reserve-memory=100Mb --publish 8761:8761 --update-delay 10s   --network network-us-west-2  -e spring_application_name=eureka --constraint  'node.role == manager' springio/eureka
docker service create --replicas 1 --name eureka-backup  --reserve-memory=100Mb --publish 8762:8762 --update-delay 10s  --network network-us-west-2 -e spring_application_name=eureka-backup --constraint 'node.role != manager' springio/eureka

Portener

docker service create \
    --network network-us-west-2 \
    --name portainer \
    --publish 9000:9000 \
    --constraint 'node.role == manager' \
    --mount type=bind,src=//var/run/docker.sock,dst=/var/run/docker.sock \
    portainer/portainer \
    -H unix:///var/run/docker.sock

Docker update Service

Update image

docker service update --image springio/client --force client docker service update --image springio/eureka --force eureka docker service update --image springio/eureka --force eureka-backup

Update replicas

docker service update --replicas 2 client docker service update --replicas 2 config

You can’t perform that action at this time.
