code-gov-update

Docker Image

This project contains code for updating the DHS code.gov inventory published here.

How it works

The LLNL/scraper project is used to scrape a handful of GitHub organizations that belong to DHS and produce an updated JSON file per the code.gov specification. If that file differs from the previously-generated one, it is emailed to the appropriate address so that it can be used to update the content hosted here.

Running

Running with Docker

To run the cisagov/code-gov-update image via Docker:

docker run cisagov/code-gov-update:0.1.7

Running with Docker Compose

1. Create a docker-compose.yml file similar to the one below to use Docker Compose.

   ---
   version: '3.7'
   
   services:
     update:
       image: 'cisagov/code-gov-update:0.1.7'
       init: true
       environment:
         - AWS_CONFIG_FILE=path/to/aws_config
         - AWS_PROFILE=default

2. Start the container and detach:

   docker compose up --detach

Using secrets with your container

This container also supports passing sensitive values via Docker secrets. Passing sensitive values like your credentials can be more secure using secrets than using environment variables. See the secrets section below for a table of all supported secret files.

1. To use secrets, create aws_config and scraper.json files containing the values you want set:

   [default]
   credential_source = Ec2InstanceMetadata
   region = us-east-2
   role_arn = arn:aws:iam::123456789012:role/AssumeSesSendEmail-CodeGovUpdate

   Please see the documentation for creating your own scraper.json configuration file.

2. Then add the secrets to your docker-compose.yml file:

   ---
   version: '3.7'
   
   secrets:
     aws_config:
       file: ./src/secrets/aws_config
     scraper_config:
       file: ./src/secrets/scraper.json
   
   services:
     update:
       image: 'cisagov/code-gov-update:0.1.7'
       init: true
       secrets:
         - source: aws_config
           target: aws_config
         - source: scraper_config
           target: scraper_config.json
       environment:
         - AWS_CONFIG_FILE=/run/secrets/aws_config
         - AWS_PROFILE=default

Updating your container

Docker Compose

1. Pull the new image from Docker Hub:

   docker compose pull

2. Recreate the running container by following the previous instructions:

   docker compose up --detach

Docker

1. Stop the running container:

   docker stop <container_id>

2. Pull the new image:

   docker pull cisagov/code-gov-update:0.1.7

3. Recreate and run the container by following the previous instructions.
