Getting Started

Building Pipelines

Building Pipelines with Scheduled Batch Processing

Local machine setup

0. Install docker
1. Run git clone -b stable https://github.com/cptn-io/el-cptn.git
2. Update the property values in .env file. Ensure that secrets, crypto keys, passwords you use are complex, random and secure.
3. Run docker compose up to start the platform.
4. Required docker images will be downloaded and the server will start up in few mins.
5. Access the service at http://localhost/

Setting up on DigitalOcean

1. Login to your DigitalOcean account.
2. Create a new droplet and login to the server.
3. Install docker on the server.
4. Run git clone -b stable https://github.com/cptn-io/el-cptn.git
5. Update the property values in .env file.
6. Run docker compose up -d to start the platform.
7. The server should be accessible at http://<your droplet ip>

To setup a custom domain for accessing your service.

8. Login to your DNS configuration and create a new A record for a domain e.g. cptn.example.com to map to your droplet's IP address.
9. Update .env file in your droplet. Change APP_URL property value to your domain cptn.example.com
10. Run docker compose restart
11. If the service is accessible, SSL certificates would automatically be provisioned for the domain and the service will be accessible via the domain url at https://cptn.example.com

Login

Login to your Service using the following default credentials. Update the .env file to change the default setup password.

Username: foo@example.com

Ready to use Apps

The platform has a mechanism to automatically download ready-to-use apps contributed by the community. These apps allow users to readily use the most common transformations or destinations. If the OOTB apps do not work, users can always modify the scripts as per their requirements.

Apps is just content and users do not need to upgrade the platform to get the latest apps. The platform will automatically check to see if there are any new apps available and download them.

The git repo supporting this functionality is at https://github.com/cptn-io/apps. Refer this page for more details on how you can build and contribute apps to the community.
