# Currency Exchange application

## Install Jenkins on OpenShift
You must install Jenkins on OpenShift.
Create a project for the Jenkins deployment:
```
oc new-project YOUR-JENKINS-PROJECT
```
Create a new Jenkins application using the `jenkins-ephemeral` template.
```
oc new-app openshift/jenkins-ephemeral -p MEMORY_LIMIT=2048Mi
```
> The `jenkins-ephemeral` template does not persist data.
If you restart the Jenkins pod, you will lose data.
Use the `jenkins-persistent` template to persist your Jenkins data.
## Jenkins agents
This demo uses Jenkins on OpenShift, which requires Jenkins Agents to run specific runtimes.
To create Node.js agent, run:
```
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-node-14 -p SOURCE_CONTEXT_DIR=jenkins/node14 | oc apply -f -
```
For the Python agent, run:
```
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-python-3 -p SOURCE_CONTEXT_DIR=jenkins/python3 | oc apply -f -
```
For Cypress:
```
oc process -f jenkins/jenkins-agent-template.yml -p NAME=jenkins-agent-cypress -p SOURCE_CONTEXT_DIR=jenkins/cypress | oc apply -f -
```
## Deployments in a test environment (for branches)
This example uses a test environment to make deployments specific to branches.
Each branch generates will generate its own deployments
Create the test project:
```
oc new-project YOUR-TEST-PROJECT
```
Allow Jenkins to deploy to this project:
```
oc policy add-role-to-user edit system:serviceaccount:YOUR-JENKINS-PROJECT:jenkins -n YOUR-TEST-PROJECT
```
## Deployments in a stage (or prod) environment
Create the stage project:
```
oc new-project YOUR-STAGE-PROJECT
```
Allow Jenkins to deploy to this project:
```
oc policy add-role-to-user edit system:serviceaccount:YOUR-JENKINS-PROJECT:jenkins -n YOUR-STAGE-PROJECT
```
## How to create the deployments in OCP
You need to create the deployments before running the Jenkins pipeline.
