Welcome, this document consists of Devtron Use Cases
Run Cron Jobs or One Time Job using Devtron Generic Helm Chart
Connect SpringBoot with Mysql Database
In this application, you will learn about how to create a Expressjs Application that connects to mongoDb.
Follow the below-mentioned steps, to deploy the application on Devtron using mongoDb Helm Chart.
To deploy mongoDb Helm Chart, you can refer to our documentation on Deploy mongoDb Helm Chart
For this example, we are using the following GitHub Repo, you can clone this repository and make following changes in the files.
This is the Dockerfile. This exposes our expressjs application to port number 8080
This file will be used to connect to our database. This will include the service-name
of the mongoDb Helm Chart, that you have deployed in Step1.
The syntax is as follows:
<service-name>:27017/<database-name>
This maps our service name to mongoDb's port number 27017.
To learn how to create an application on Devtron, refer to our documentation on Creating Application
In this example, we are using the url of the forked Git Repository.
Give, the path of the Dockerfile.
Enable Ingress
, and give the path on which you want to host the application.
Set up the CI/CD pipelines. You can set them to trigger automatically or manually.
Trigger the CI Pipeline, build should be Successful, then trigger the CD Pipeline, deployment pipeline will be initiated, after some time the status should be Healthy
Check the Expressjs app connected to mongodb database, running successfully by hitting your application url.
The syntax is: http://<hostname>/<path>/
path will be the one that you have given in Step 3 while configuring the Deployment Template.
The output of our application would be as follows:
You can see that we are getting the JSON response. We have successfully connected our expressjs application to the mongoDb database.
This document will help you to deploy a sample Spring Boot Application, using mysql Helm Chart
To deploy mysql Helm Chart, you can refer to our documentation on Deploy mysql Helm Chart
For this example, we are using the following GitHub Repo, you can clone this repository and make following changes in the files.
Set the database configuration in this file.

It exposes 3 REST endpoints for it's users to create, to view specific student record and view all student records.
To test Rest API, you can use curl command line tool
Create a new Student Record
Create a new POST request to create a new Transaction. Once the transaction is successfully created, you will get the student id as a response.
Curl Request is as follows:
View All Student's Data
To view all student records, GET Request is:
path will be the one that you have given in Step 3 while configuring the Deployment Template.
http://<hostname>/<path>/viewAll
View student's data By student ID
To view student data by student id, GET Request is:
http://<hostname>/<path>/view/<id>
path will be the one that you have given in Step 3 while configuring the Deployment Template.
Django is a free, open-source web framework written in Python programming language. It allows for scalability, re-usability, and rapid development. Django can be connected to different databases like MySQL, PostgreSQL, etc.
To deploy mysql Helm Chart, you can refer to our documentation on Deploy mysql Helm Chart
For this example, we are using the following GitHub Repo, you can clone this repository and make following changes in the files.
Go to mysite/settings.py.
The settings.py
contains the configuration for your SQL database. Make sure the configurations in settings.py
matches the configurations of the mysql Helm Chart, that you have deployed in Step 1.
