Deploy Applications to IBM Cloud

1. Deploy Applications to IBM Cloud

Source:

1.1. Create a Quarkus Project

mvn io.quarkus:quarkus-maven-plugin:1.7.2.Final:create \
    -DprojectGroupId=at.htl \
    -DprojectArtifactId=config-quickstart \
    -DclassName="at.htl.config.GreetingResource" \
    -Dpath="/greeting"
cd config-quickstart
idea .

open a terminal

./mvnw clean compile quarkus:dev

cURL

curl -w "\n" http://localhost:8080/greeting

hello

httpie

http :8080/greeting

HTTP/1.1 200 OK
Content-Length: 5
Content-Type: text/plain;charset=UTF-8

hello

./mvnw quarkus:add-extension -Dextensions="kubernetes, container-image-docker"

1.2. Package the Application

application.properties

quarkus.kubernetes.part-of=todo-app
quarkus.container-image.name=getting-started
quarkus.container-image.tag=1.0
quarkus.container-image.registry=
quarkus.container-image.group=
quarkus.kubernetes.service-type=NodePort (1)

1	The default value `ClusterIP` is not working with minikube.

./mvnw clean package

There should be a BUILD SUCCESS.
Examine the target/kubernetes/kubernetes.yml - file.
Notice the Service- and Deployment-Sections in the yml-file.

1.3. Deploy to minikube

quarkus.kubernetes.part-of=todo-app
quarkus.container-image.name=getting-started
quarkus.container-image.tag=1.0
quarkus.container-image.registry=
quarkus.container-image.group=
quarkus.kubernetes.image-pull-policy=never
quarkus.kubernetes.service-type=NodePort

./mvnw clean package -Dquarkus.kubernetes.deploy=true

[INFO] [io.quarkus.kubernetes.deployment.KubernetesDeployer] Deploying to kubernetes server: https://127.0.0.1:32772/ in namespace: default.

kubectl get pod
kubectl get deploy
kubectl get svc

Hier sieht man den Port des Nodeport

minikube ip

Mit minikube ip kann man die Ip von minikube abrufen

curl <ip-von-minikube>/<port-von-nodeport>/greeting

This didn’t work under MacOS.
In this case you have to open a tunnel with minikube.

minikube service getting-started

terminal output

|-----------|-----------------|-------------|-------------------------|
| NAMESPACE |      NAME       | TARGET PORT |           URL           |
|-----------|-----------------|-------------|-------------------------|
| default   | getting-started | http/8080   | http://172.17.0.4:31908 |
|-----------|-----------------|-------------|-------------------------|
🏃  Starting tunnel for service getting-started.
|-----------|-----------------|-------------|------------------------|
| NAMESPACE |      NAME       | TARGET PORT |          URL           |
|-----------|-----------------|-------------|------------------------|
| default   | getting-started |             | http://127.0.0.1:57075 |
|-----------|-----------------|-------------|------------------------|
🎉  Opening service default/getting-started in default browser...
❗  Because you are using a Docker driver on darwin, the terminal needs to be open to run it.

The browser opens and show the webpage
add /greeting to the url and it works
with ` minikube service getting-started --url` you only print out the url.
don’t forget NOT to close the terminal, because it would close the tunnel too.

1.4. IBM Cloud Internet Services

First sign up for a cloud account. Choose the type "lite".
Install the ibm-cloud-cli
- on macos: don’t use brew - there are problems when docker is already installed
- on all OS use the installer or the shell

ibmcloud login
ibmcloud plugin install container-service
ibmcloud plugin install container-registry
ibmcloud plugin install observe-service
ibmcloud plugin list
