🔧 Configuration

You can modify the following configuration settings in the .env file:

• HOSTNAME: This is the hostname for the server that is running the service. It is used to identify the server in the logs.
• API_KEY: This is your Rapid7 Log Search API key. You can find it in the Log Search UI under Settings > API Keys.
• LOG_REGION: This is the region where your Rapid7 Log Search account is hosted.
• DOCKER_PATH: This is the path to the Docker socket. It is used to listen to Docker events. You can leave this as the default value unless you have a custom Docker socket path.

Installation 💻

There are two ways to run this service: using Docker or Node.js. The Docker image is recommended for most users, but if you want to run the service on a machine that doesn't have Docker installed, you can use Node.js instead.

Using Docker 🐳

1. Create a new file called docker-compose.yml and copy the following contents into it:

   version: "3.8"
   services:
     cloudflare-ddns:
       image: realshaunoneill/cloudflare-ddns:latest
       container_name: cloudflare-ddns
       restart: unless-stopped
       environment:
         - HOSTNAME=
         - API_KEY=
         - LOG_REGION=

2. Modify the environment variables to your liking. See Configuration for more information.

3. Run the service:

   docker-compose up -d

Using Node.js 💻

1. Clone this repository to your local machine:

   git clone git@github.com:realshaunoneill/docker-log-tailer.git

2. Install the dependencies:

   npm install

3. Copy the .env.example file to .env and modify the values to your liking. See Configuration for more information. The .env file is used to store your Cloudflare API key and other configuration options. It is ignored by Git, so you don't have to worry about accidentally committing your API key to the repository. You can copy the .env.example file to .env using the following command:

   cp .env.example .env

4. Run the service:

   npm start

5. (Optional) If you want to run the service in the background, you can use a process manager like PM2:

   npm install pm2 -g
   pm2 start index.js --name cloudflare-ddns
