client-cert-update

Docker Image

This project contains code for sending FNR BOD an updated list of the live websites in .gov that require authentication via client certificates.

Running

Running with Docker

To run the cisagov/client-cert-update image via Docker:

docker run cisagov/client-cert-update:0.1.4

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/client-cert-update:0.1.4
       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 scan_read_creds.yml 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 cisagov/mongo-db-from-config project for creating your own scan_read_creds.yml file.

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

   ---
   version: "3.7"
   
   secrets:
     aws_config:
       file: ./src/secrets/aws_config
     scan_read_creds:
       file: ./src/secrets/scan_read_creds.yml
   
   services:
     update:
       image: cisagov/client-cert-update:0.1.4
       init: true
       environment:
         - AWS_CONFIG_FILE=/run/secrets/aws_config
         - AWS_PROFILE=default
       secrets:
         - source: aws_config
           target: aws_config
         - source: scan_read_creds
           target: scan_read_creds.yml
