Setting up DIVOC development environment

This will cover the following:

Running DIVOC on a local machine


Step 1: Install prerequisites and dependencies
  • Update package list - sudo apt-get update.
  • Install docker - sudo apt install docker.io.
  • Install docker-compose - sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose.
  • Install git - sudo apt install git.
  • For additional details on Docker, you can find the instructions here.
  • You can find the basic Docker Compose commands below:
- Starting services docker-compose up.
- Restarting services docker-compose restart.
- Checking the status of services docker-compose ps.
- Monitoring service logs docker-compose logs.
Step 2: Install DIVOC
  • Clone DIVOC repository onto your local machine - git clone https://github.com/egovernments/DIVOC.
  • Navigate to DIVOC directory - cd DIVOC.
  • Configure DIVOC: Configurations are provided as environment variables and a default set of configurations is provided in the ‘.env.example’ file. Make a copy of this file named ‘.env’ that docker will pick up. Edit these configurations as per your need.
'cp .env.example .env'
Step 3: Start all services in the detached mode.
docker-compose up -d
  • Verify the state of containers. All containers should be up.
  • Some services might fail to start because the dependent service may not be ready yet. Restarting the failed service should start it successfully in this case.
  • On Mac/Windows, services may crash with exit code:137, if sufficient memory is not set for docker. This can be changed in the Docker desktop preferences, resources tab, as shown here.
Step 4: To build docker images locally after making changes, run following commands
make docker
make docker docker-compose up -d
Step 5: Explore DIVOC
  • The following are the routes to access local apps. The remaining routes can be found in nginx/nginx.conf.
public app
portal app
facility app
