Example CRUD Application
First, install the dependencies
npm install
A Postgres DB is needed, so if you are using Docker, then you can start a postgres db easily.
docker run --name os-postgres-db -e POSTGRESQL_USER=luke -e POSTGRESQL_PASSWORD=secret -e POSTGRESQL_DATABASE=my_data -d -p 5432:5432 centos/postgresql-10-centos7
In this example, the db user is luke
, the password is secret
and the database is my_data
You can then start the application like this:
DB_USERNAME=luke DB_PASSWORD=secret ./bin/www
Then go to http://localhost:3000
First, make sure you have minishift setup and are logged in using oc login
.
Then create a new project using the oc
commands
oc new-project fun-node-fun
For this example, you will also need a postgres db running on your Minishift cluster.
oc new-app -e POSTGRESQL_USER=luke -ePOSTGRESQL_PASSWORD=secret -ePOSTGRESQL_DATABASE=my_data centos/postgresql-10-centos7 --name=my-database
Then run npm run openshift
to deploy your app
Then you can navigate to the newly exposed route, something similar to "http://nodejs-rest-http-crud-redhat-boosters.192.168.99.100.nip.io/", this will probably be different based on your Minishift IP address
This app has an example of integration test using an integration test tool for Node.js apps on OpenShift
Once you started your local OpenShift instance you can check it out by running the following commands:
npm run test:integration
It will deploy the app to local OpenShift and run the tests located on test/integration
directory.
npm run test:integration:undeploy
Performs undeploy of the app inside local OpenShift.
