Install and run docker and kubernetes. In case if you already have such environment, you can skip this step. For local environment we will use Ubuntu 16.04.3 LTS.
Steps are following:
- Install java 8 and maven
- Install docker
- Install kubectl and minikube
- Start docker registry
docker run -d -p 5000:5000 --restart=always --name registry registry:2
- Check is registry running
ubuntu@starter:~/msstarter$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6d21e786f897 registry:2 "/entrypoint.sh /e..." 17 hours ago Up 17 hours 0.0.0.0:5000->5000/tcp registry
- Start kubernetes via minikube, wait a minute and check is it running
ubuntu@starter:~/msstarter$ sudo minikube start --vm-driver=none
Starting local Kubernetes v1.7.5 cluster...
Starting VM...
Getting VM IP address...
....... skipped .............
ubuntu@starter:~/msstarter$ sudo chown -R $USER $HOME/.kube
ubuntu@starter:~/msstarter$ sudo chgrp -R $USER $HOME/.kube
ubuntu@starter:~/msstarter$ sudo chown -R $USER $HOME/.minikube
ubuntu@starter:~/msstarter$ sudo chgrp -R $USER $HOME/.minikube
- Check is kubernetis running ?
ubuntu@starter:~$ kubectl get po --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system kube-addon-manager-starter 1/1 Running 0 3h
kube-system kube-dns-6fc954457d-cfp28 3/3 Running 0 3h
kube-system kubernetes-dashboard-rw8lv 1/1 Running 0 3h
git clone https://github.com/iazarny/msstarter.git
cd msstarter
mvn package docker:build docker:push
The "uber" yaml will be created during build procedure. It shall be used to launch entire example
kubectl create -f k8s/deploy-all.yml
Expose service(s) on some IP addresses. Actually st-zuul-web is enough.
kubectl expose deployment st-zuul-web --port=8081 --target-port=8080 --name=ext-st-zuul-web --external-ip=172.28.128.3
kubectl expose deployment st-rest --port=8082 --target-port=8080 --name=ext-st-rest --external-ip=172.28.128.3
kubectl expose deployment st-eureka --port=8083 --target-port=8080 --name=ext-st-eureka --external-ip=172.28.128.3
kubectl expose deployment st-kibana --port=5601 --target-port=5601 --name=ext-st-kibana --external-ip=172.28.128.3
kubectl expose deployment st-elasticsearch --port=9200 --target-port=9200 --name=ext-st-elasticsearch --external-ip=172.28.128.3
- Vue UI shall be available http://172.28.128.3:8081
- Get all arcticles http://172.28.128.3:8081/api/articles and http://172.28.128.3:8082/api/articles
- Swagger http://172.28.128.3:8082/swagger-ui.html http://172.28.128.3:8082/v2/api-docs

- Kibana http://172.28.128.3:5601
- In case if you are facing with some issues running kubernetes via minikube try to specify additional configuration for k8s
sudo minikube start --vm-driver=none --kubernetes-version=v1.7.5 --extra-config=apiserver.ServiceClusterIPRange=10.0.0.0/24
- In case if services not available outside of VM try to check firewall and allow message forwarding.
sudo iptables -t filter --policy FORWARD ACCEPT
- Default ubuntu image has 10Gb disk size. It is not enough to development. Solution - resize disk.
VBoxManage clonehd "ubuntu-xenial-16.04-cloudimg.vmdk" "cloned.vdi" --format vdi
VBoxManage modifyhd "cloned.vdi" --resize 51200
