# Demo app for testing Liveness and Readiness Probes in minikube
See https://cloud.redhat.com/blog/liveness-and-readiness-probes
## Custom readiness probe
```shell
curl -X GET http://localhost:8090/actuator/health
```
```shell
curl -X GET http://localhost:8080/readyz
```
## Set custom delay for health check response
```shell
curl -X PUT http://localhost:8080/delay -H "Content-Type: application/json" -d '{"newDelayInSeconds": 2}'
```
## Custom workload endpoint
```shell
curl -X GET "http://localhost:8080/api/v1/workload/now?delay=10"
```
### Run Gatling
```shell
./gradlew gatlingRun
```
Or with custom params:
```shell
./gradlew gatlingRun -Drps=2 -DdurationSec=15 -DhostName=http://localhost:8080
```
## Build docker image
## With curl
```shell
./gradlew dockerBuildImage
```
### Lightweight image
```shell
./gradlew bootBuildImage --imageName=io.github.mfvanek/minikube-demo:0.0.1
```
## Run in Docker
```shell
docker run --name minikube-demo -d -p 8080:8080 -t io.github.mfvanek/minikube-demo:latest
```
### Show logs
```shell
docker logs minikube-demo
```
### Remove container
```shell
docker rm -f minikube-demo
```
## Prepare minikube
https://minikube.sigs.k8s.io/docs/start/
### Config
```shell
minikube config view
```
```shell
minikube config set memory 10000
minikube config set cpus 5
minikube config set driver docker
```
### Start
```shell
minikube start --force --extra-config=kubelet.cgroup-driver=systemd --container-runtime=docker
```
```shell
minikube status
```
### Clean
```shell
minikube delete --all
```
```shell
minikube delete --all --purge
```
### Dashboard
```shell
minikube dashboard
```
## Load image to minikube
```shell
minikube image load io.github.mfvanek/minikube-demo:0.2.2
```
```shell
minikube image ls --format table
```
## Run pod
```shell
minikube kubectl -- run minikube-demo --image=io.github.mfvanek/minikube-demo:0.0.1 --port=8080 --image-pull-policy Never
minikube kubectl -- get pods
minikube kubectl -- delete pod minikube-demo
```
### Get pod details
```shell
minikube kubectl -- get pods
minikube kubectl get endpoints
minikube kubectl describe svc minikube-demo-service
```
## Deploy to minikube
```shell
minikube kubectl -- create -f k8s-deployment.yaml
```
```shell
minikube kubectl -- apply -f k8s-deployment.yaml
```
## Expose service
```shell
minikube service minikube-demo-service --url
```
