##Dealing with SSL/TLS

Generate some private keys and truststores

keytool -genkey \
    -alias kafka2cloudevent  \
    -storepass password \
    -keyalg RSA \
    -storetype PKCS12 \
    -dname "cn=kafka2cloudevent" \
    -validity 365000 \
    -keystore tls/keystore.p12

keytool -export \
    -alias kafka2cloudevent \
    -rfc \
    -storepass password \
    -keystore tls/broker-keystore.p12 \
    -file tls/kafka2cloudevent.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
done

keytool -list -storepass password -keystore tls/keystore.p12 -v
keytool -list -storepass password -keystore tls/truststore.p12 -v

To deploy directly on openshift

make sure you have the image streams deployed

BASEURL=https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-780019-redhat-00005

oc create -n openshift -f ${BASEURL}/fis-image-streams.json
oc replace -n openshift -f ${BASEURL}/fis-image-streams.json

oc create secret generic kafka2cloudevent-tls-secret \
--from-file=keystore.p12=tls/keystore.p12 \
--from-file=truststore.p12=tls/truststore.p12

oc create secret generic kafka2cloudevent-prop-secret \
--from-file=application.properties=src/main/resources/application.properties

mvn -P ocp fabric8:deploy fabric8:build

Run local container with specific network and IP address

docker stop kafka2cloudevent
docker rm kafka2cloudevent
docker rmi kafka2cloudevent
docker build -t kafka2cloudevent .
docker run -d --net primenet --ip 172.18.0.10 --name kafka2cloudevent -e SPRING_PROFILES_ACTIVE=dev kafka2cloudevent

Stop or launch multple instaces

NB_CONTAINERS=2
for (( i=0; i<$NB_CONTAINERS; i++ ))
do
   docker stop kafka2cloudevent-$i
   docker rm kafka2cloudevent-$i
done

docker rmi kafka2cloudevent
docker build -t kafka2cloudevent .

for (( i=0; i<$NB_CONTAINERS; i++ ))
do
    docker run -d --net primenet --ip 172.18.0.1$i --name kafka2cloudevent-$i -e SPRING_PROFILES_ACTIVE=dev kafka2cloudevent
done

To release without deploying straight to an ocp cluster

mvn  -P ocp package

To deploy using binary build on ocp

tar xzvf kafka2cloudevent-ocp.tar.gz
cd kafka2cloudevent
oc apply -f openshift.yml
oc start-build kafka2cloudevent-s2i --from-dir=deploy --follow

Push on dockerhub

docker login
docker build -t kafka2cloudevent -f DockerfileCommunity .
docker tag kafka2cloudevent:latest alainpham/kafka2cloudevent:latest
