Add a new Parse application to a Datica CPaaS Environment

James Kearney -

This guide outlines how to add a new Parse application to a Datica CPaaS environment.

 

Variables

The following variables used in this guide should be replaced with values specific to your environment:

Variable Description
<env-name> Replace with the name of your environment (e.g. "myapp-staging")
 <code-service-name> Replace with the name of your application's code service (e.g. "parse-app") 
 <app-id> A unique ID for this Parse application. Generate this on your own.
<master-key-uuid> UUID secret key for this Parse database. Generate this on your own.
<app-name> The name of this application (no spaces). Used to set the URI path in the Parse Dashboard (e.g. https://parse.example.com/<app-name>)
<parse-app-fqdn>  Replace with the fully qualified domain name for your parse application (e.g. "parse.example.com"). This should be different than your parse dashboard fqdn.

 

Steps

1. Add a MongoDB service for data storage

Add a new MongoDB service to your environment with the following parameters:

name: <app-name>-db

Scale: 1
RAM: 1 GB
CPU: 1
Storage: 20 GB

 

2. Add the Parse application code service

Create a new code service with the following characteristics:

Scale: 1
Worker Scale: 0
RAM: 1 GB
CPU: 1

We advise naming your code service something relevant to your application, or something like "parse-app".

3. Configure environment variables

Use the Datica CLI to add the following environment variables to the code service you created in step 2 (refer to the Environment Variables guide for more information about adding & updating environment variables)

APP_ID=<app-id>
MASTER_KEY=<master-key-uuid>
PARSE_SERVER_APP_NAME=<app-name>
PARSE_SERVER_MOUNT_PATH=/<app-name>
SERVER_URL=https://<parse-app-fqdn>/<app-name>

Use the Datica CLI to update the following environment variables for the code service you created in step 2.

IMPORTANT: For this step, you'll need to first retrieve the current values using `datica vars list`, and then update them using `datica vars set`.


DATABASE_1_URL -- replace "/catalyze" with "/<app-name>"
DATABASE_URL -- replace "/catalyze" with "/<app-name>"

 

4. Initialize the code repository

mkdir ./<app-name>

git clone git@github.com:catalyzeio/stratum-parse-server.git <app-name>-parse-server

cd /path/to/<app-name>-parse-server

git remote remove origin

datica init

Follow the prompts to configure the repository. When prompted for a code service name, use the name of the code service you created in step 2 of this section.

 

5. Configure the Service Proxy

In order to use the Parse application, it must be exposed through the environment's service proxy. The following steps will create a new site definition and associate it with the code service you created in step 2. This example uses LetsEncrypt for TLS security.

datica -E "<env-name>" sites create <parse-app-fqdn> <code-service-name> --lets-encrypt

 

6. Deploy the Parse application

cd /path/to/your/<app-name>-parse-server

git push datica master 

 

Once your code services are redeployed, you can add the application to your Parse dashboard by following our instructions for Adding a Parse application to the Parse Dashboard.
