While you can run and interact with this booster on localhost, you cannot take advantage of using the health check functionality with this booster without using OpenShift. For more details on using this booster with a single-node OpenShift cluster, CI/CD deployments, as well as the rest of the runtime, see the Node.js Runtime Guide. |
Important
|
This booster requires Node.js 8.x or greater and npm 5 or greater.
|
Important
|
As part of the process of creating this booster, developers.redhat.com/launch or the Fabric8 Launcher tool set up a project with a CI/CD deployment of this booster. You can see the status of this deployment in your Single-node OpenShift Cluster or OpenShift Online Web Console. |
To run this booster on your local host:
$ git clone git@github.com:abdou31/projetcloud
$ cd projetcloud
$ npm install && npm start
To interact with your booster while its running, use the form at http://localhost:8080
or the curl
command:
$ curl http://localhost:8080/api/greeting
{"content":"Hello, World!"}
$ curl http://localhost:8080/api/greeting?name=Sarah
{"content":"Hello, Sarah!"}
If you have a single-node OpenShift cluster, such as Minishift or Red Hat Container Development Kit, installed and running, you can also deploy your booster there. A single-node OpenShift cluster provides you with access to a cloud environment that is similar to a production environment.
To deploy your booster to a running single-node OpenShift cluster:
-
Log in and create your project.
$ oc login -u developer -p developer $ oc new-project MY_PROJECT_NAME $ npm install && npm run openshift
To interact with your booster while it’s running on a Single-node OpenShift Cluster, you first need to obtain it’s URL:
$ oc get route booster-health-check-nodejs -o jsonpath={$.spec.host}
booster-health-check-nodejs-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME
You can use the form at your application’s url or you can use the curl
command:
$ curl http://booster-health-check-nodejs-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting
{"content":"Hello World!"}
$ curl http://booster-health-check-nodejs-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/greeting?name=Sarah
{"content":"Hello Sarah!"}
$ curl http://booster-health-check-nodejs-MY_PROJECT_NAME.LOCAL_OPENSHIFT_HOSTNAME/api/stop
$ oc get pods -w
NAME READY STATUS RESTARTS AGE
booster-health-check-nodejs-1-26iy7 1/1 Running 5 18m
When READY
changes to 0/1
, if you re-execute a curl
command to api/greeting
or attempt to access the application’s URL, it will be unavailable. When READY
changes back to 1/1
, curl
commands and the application URL will be available again.
You can learn more about this booster and rest of the Node.js runtime in the Node.js Runtime Guide.
