http-dockerized-sample

in this sample we have created sample rest controller and two simple services.

running project

in order to run project create project image with following command:

docker build -t docker-sample:0.0.1 .

then you can run it with following command:

docker run -p 8089:8080 docker-sample

you can define your default port on creating image wiht following command:

docker build -t docker-sample --build-arg ENV_PORT=8097 .

then you have to bind your container port(8097 in example) to host port as below:

docker run -p 8097:8097 docker-sample

following logs show that your application is starting on port 8097:

2022-08-04T14:25:54.452 [INFO] requestId:[] clientIP:[ ] thread:[main ] userIP:[] c.t.m.h.config.ServerPortCustomizer.customize@20: starting program on port: 8097

your also can specify environment variable on running container and change application port:

docker run -p 8099:8099 --env SAMPLE_APP_PORT=8099 docker-sample

below logs show that your environment variable is overriden and application is starter on port 8099

2022-08-04T14:27:03.304 [INFO] requestId:[] clientIP:[ ] thread:[main ] userIP:[] c.t.m.h.config.ServerPortCustomizer.customize@20: starting program on port: 8099

for applying sample pod use below command:

kubectl apply -f docker-sample-pod.yaml

for applying sample replicaSet use below command:

kubectl apply -f docker-sample-replicaset.yaml

for applying sample deployment use below command:

kubectl apply -f docker-sample-deployment.yaml

for applying sample service use below command:

kubectl apply -f docker-sample-service.yaml
