Usage

Start with getting Docker then do the following:

Create the setup files

Create a docker-compose.yml

services:
  db:
    image: postgres:17.2
    container_name: postgres-db
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: RootPassword
      POSTGRES_DB: ti1
    ports:
      - "5432:5432"
    volumes:
      - ./postgres_data:/var/lib/postgresql/data  # Store data in the current directory
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql:ro
    networks:
      - app-network
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "postgres", "-d", "ti1", "-h", "db"]
      interval: 10s
      retries: 5
    restart: always  # Ensure the container always restarts
 
  valkey:
    image: valkey/valkey:latest
    container_name: valkey
    environment:
      VALKEY_PASSWORD: the_valkey_password
    ports:
      - "6379:6379"
    volumes:
      - ./valkey_data:/data
    networks:
      - app-network
    restart: always  # Ensure the container always restarts
 
  ti1-container:
    image: pigwin1/ti1:dev
    container_name: ti1-container
    environment:
      DB_HOST: db
      DB_PORT: 5432
      DB_USER: ti1
      DB_PASSWORD: ti1password
      DB_NAME: ti1
      DB_SSLMODE: disable
      VALKEY_HOST: valkey
      VALKEY_PORT: 6379
      VALKEY_PASSWORD: the_valkey_password
    depends_on:
      db:
        condition: service_healthy  # Wait until the db service is healthy
      valkey:
        condition: service_started  # Wait until the valkey service is started
    networks:
      - app-network
    restart: always  # Ensure the container always restarts
 
networks:
  app-network:
    driver: bridge
 
volumes:
  postgres_data:
    driver: local
  valkey_data:
    driver: local

Create init.sql

-- Check if 'post' user exists; create if not
DO $$
BEGIN
    IF NOT EXISTS (SELECT FROM pg_roles WHERE rolname = 'post') THEN
        CREATE ROLE post WITH LOGIN PASSWORD 'postpassword';
        GRANT ALL PRIVILEGES ON DATABASE ti1 TO post;
        ALTER ROLE post WITH SUPERUSER;
    END IF;
END
$$;

-- Check if 'ti1' user exists; create if not
DO $$
BEGIN
    IF NOT EXISTS (SELECT FROM pg_roles WHERE rolname = 'ti1') THEN
        CREATE ROLE ti1 WITH LOGIN PASSWORD 'ti1password';
        GRANT ALL PRIVILEGES ON DATABASE ti1 TO ti1;
        GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO ti1;
        GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO ti1;
        GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public TO ti1;
-- Grant the ti1 user the necessary permissions on the public schema
GRANT USAGE, CREATE ON SCHEMA public TO ti1;

-- Grant all permissions (SELECT, INSERT, UPDATE, DELETE, etc.) on all existing tables in the public schema
GRANT ALL ON ALL TABLES IN SCHEMA public TO ti1;

-- Grant all permissions on all existing sequences in the public schema
GRANT ALL ON ALL SEQUENCES IN SCHEMA public TO ti1;

-- Grant all permissions on all functions in the public schema
GRANT ALL ON ALL FUNCTIONS IN SCHEMA public TO ti1;

-- Ensure that the ti1 user will have access to new tables, sequences, and functions created in the public schema
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON TABLES TO ti1;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON SEQUENCES TO ti1;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON FUNCTIONS TO ti1;

-- Optionally, grant full permissions on the entire database to ti1 (if needed)
-- GRANT ALL PRIVILEGES ON DATABASE ti1 TO ti1;

    END IF;
END
$$;

Remember to change the password values

Run the Docker Containers

docker compose up -d

edit the postgress config (optinal)

open the config file

nano postgres_data/postgresql.conf

Change the following values

listen_addresses = '*'
max_connections = 200
shared_buffers = 16GB
work_mem = 256MB
maintenance_work_mem = 2GB
dynamic_shared_memory_type = posix
max_wal_size = 1GB
min_wal_size = 80MB

set these to what makes most sense for you

These values should also be set bet not necessarily changed

log_timezone = 'Etc/UTC'
datestyle = 'iso, mdy'
timezone = 'Etc/UTC'
lc_messages = 'en_US.utf8'
lc_monetary = 'en_US.utf8'
lc_numeric = 'en_US.utf8'
lc_time = 'en_US.utf8'
default_text_search_config = 'pg_catalog.english'
