The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

Creating a native executable

You can create a native executable using: mvn package -Pnative.

You can then execute your native executable with: ./target/version-watcher-1.0.0-runner

Run local container with specific network and IP address

Optionally you can create a separate local docker network for this app

docker network create --driver=bridge --subnet=172.18.0.0/16 --gateway=172.18.0.1 primenet 

docker stop version-watcher
docker rm version-watcher
docker rmi version-watcher

docker build -f src/main/docker/Dockerfile.multiarch -t version-watcher:1.0.0 .

docker run --rm version-watcher:1.0.0

docker run -d --net primenet --ip 172.18.0.10 --name version-watcher version-watcher:1.0.0

Launch multple instaces

NB_CONTAINERS=2

for (( i=0; i<$NB_CONTAINERS; i++ ))
do
    docker run -d --net primenet --ip 172.18.0.1$i --name version-watcher-$i version-watcher:1.0.0
done

for (( i=0; i<$NB_CONTAINERS; i++ ))
do
   docker stop version-watcher-$i
   docker rm version-watcher-$i
done

Push on registry and deploy on kube

change to your registry and ingress root domain

export localregistry=alainpham
export kube_ingress_root_domain=kube.loc 

mvn clean package -DskipTests

docker build -f src/main/docker/Dockerfile.multiarch -t version-watcher:1.0.0 .
docker tag version-watcher:1.0.0 ${localregistry}/version-watcher:1.0.0
docker push ${localregistry}/version-watcher:1.0.0

envsubst < src/main/kube/deploy.envsubst.yaml | kubectl delete -f -
envsubst < src/main/kube/deploy.envsubst.yaml | kubectl apply -f -

##Dealing with SSL/TLS

Generate some private keys and truststores

keytool -genkey \
    -alias version-watcher  \
    -storepass password \
    -keyalg RSA \
    -storetype PKCS12 \
    -dname "cn=version-watcher" \
    -validity 365000 \
    -keystore tls/keystore.p12

keytool -export \
    -alias version-watcher \
    -rfc \
    -storepass password \
    -keystore tls/broker-keystore.p12 \
    -file tls/version-watcher.pem

FILES=tls/trusted-certs/*
for f in $FILES
do
    full="${f##*/}"
    extension="${full##*.}"
    filename="${full%.*}"
    echo "importing $full in alias $filename"

    keytool -import \
        -alias $filename \
        -storepass password\
        -storetype PKCS12 \
        -noprompt \
        -keystore tls/truststore.p12 \
        -file $f
