The Sealog-Server and MongoDB database can be deployed as a Docker container. The repo includes a docker-compose.yaml and Dockerfile to help operators setup deployments. Utilizing containerization is a great way to evaluatate Sealog or when developing custom code. Using containers requires Docker Desktop or another container hosting environment.

docker-compose.yml

The included docker-compose.yml.dist file will build a basic Sealog-Server and MongoDB package ready for evaluation, development or production. The inline documentation describes how to customize the deployment such as define the access port and setting up TLS (https).

services:
  sealog-server:
    build:
      context: .
      dockerfile: Dockerfile
    depends_on:
      - mongo
    environment:
      #- SEALOG_SERVER_PORT=8000
      #- SEALOG_SERVER_FILEPATH_ROOT=/data/sealog-files
      #- SEALOG_SERVER_TLS_PRIVKEY=<privkey.pem>
      #- SEALOG_SERVER_TLS_FULLCHAIN=<fulchain.pem>
      
      # Create SEALOG_SERVER_SECRET with:
      # node -e "console.log(require('crypto').randomBytes(256).toString('base64'));"
      - SEALOG_SERVER_SECRET='<SECRET_TOKEN>'
      
      # NODE_ENV Options are:
      # - production: what to use for realz
      # - development: preloads some events, event templates cruises and lowerings
      # - demo-vessel: preloads some event templates, cruises, and events... good for evaluating Sealog for vessels
      # - demo-vehicle: preloads some event templates, cruises, lowerings and events... good for evaluating Sealog for vehicles
      - NODE_ENV=demo-vessel
      - MONGO_URL=mongodb://mongo:27017/sealogDB
    image: sealog-server
    ports:
      - "8000:8000"
    restart: unless-stopped
    volumes:
      # Make sure this directory exists
      - /data/sealog-files:/data/sealog-files

Dockerfile

# Use the latest Node.js Alpine image as the base image
FROM node:lts-alpine

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code to the working directory
COPY . .

# Copy configuration files
COPY config/db_constants.js.dist config/db_constants.js
COPY config/email_settings.js.dist config/email_settings.js
COPY config/manifest.js.dist config/manifest.js
COPY config/server_settings.js.dist config/server_settings.js
COPY config/secret.js.dist config/secret.js

# Expose port 8000 (This needs to match what's in the docker-compose.yml file)
EXPOSE 8000

# Command to run the Node.js application
CMD [ "node", "server.js" ]

Usage

To use/customize the deployment, first copy/rename the distributed versions.

cd /opt/sealog-server
cp docker-compose.yaml.dist docker-compose.yaml
cp Dockerfile.yaml.dist Dockerfile.yaml

Next you will need to create a SECRET_TOKEN and add it to the docker_compose.yml file. The command to create the token is included as a comment in the docker_compose.yml file.

Next build and start the container.

docker-compose build
docker-compose up

If there were no problems with configuring and building the container then there should be a working instance of Sealog-Server available on port 8000.
