Run a simple application with three different orchestrators:
- docker-compose
- kubernetes
- openshift
The platform consists of two services: a PHP web service and a MySQL database.
-
Open a console, terminal or CMD, start the application and wait for for both services to complete its starting proccesses
$ docker-compose -f docker-compose/docker-compose.yml up --build [...]
The application will start in "foreground" mode, so your cannot interact with the console and it will swow the platform logs

-
Point your browser to the application endpoint at http://localhost:8080/docker-php/index.php and do some tests, sending new comments to the "User coments" list.
-
Stop your application using "ctrl-c" over the console. You can remove all stuff in addition with
docker-compose down --rmi all --volumes:[...] webservice | 172.21.0.1 - - [08/Mar/2020:20:58:18 +0000] "GET /favicon.ico HTTP/1.1" 404 489 "http://localhost:8080/docker-php/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36" webservice | 172.21.0.1 - - [08/Mar/2020:20:58:19 +0000] "GET /favicon.ico HTTP/1.1" 404 489 "http://localhost:8080/docker-php/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36" webservice | 172.21.0.1 - - [08/Mar/2020:20:59:08 +0000] "-" 408 0 "-" "-" ^CGracefully stopping...

Install minikube and prepare the images
$ minikube start [...] $ eval $(minikube docker-env) $ docker build -f docker-compose/Dockerfile -t webservice docker-compose [...] $ docker build -f docker-compose/DockerfileMysql -t database docker-compose [...]
You can use a kubernetes installation instead minikube. Take a look at Okteto or k8spin.
-
Start to work
$ kubectl create -f kubernetes-openshift/database-deployment.yaml,kubernetes-openshift/database-service.yaml,kubernetes-openshift/webservice-deployment.yaml,kubernetes-openshift/webservice-service.yaml,kubernetes-openshift/webservice-ingress.yaml [...]
-
Show you the cluster status in kubernetes dashboard
$ minikube dashboard [...]
-
To stop everything
$ kubectl delete -f kubernetes-openshift/database-deployment.yaml,kubernetes-openshift/database-service.yaml,kubernetes-openshift/webservice-deployment.yaml,kubernetes-openshift/webservice-service.yaml,kubernetes-openshift/webservice-ingress.yaml [...] $ minikube stop [...] $ minikube delete [...]
