Postgres

docker volume create postgres
docker run -d \
   -p 127.0.0.1:5432:5432 \
   -v postgres:/var/lib/postgresql/data \
   --name postgres \
   -e POSTGRES_PASSWORD=mysecretpassword \
   --restart always \
   postgres:14.4

docker exec -it postgres psql "postgres://postgres:mysecretpassword@localhost:5432/postgres" -c "DROP DATABASE camera_db"
docker exec -it postgres psql "postgres://postgres:mysecretpassword@localhost:5432/postgres" -c "CREATE DATABASE camera_db"

Check DB_CONNECTION from .env.

NOTE: psycopg is installed in binary mode.

MinIO

docker volume create minio
docker run \
   -p 9000:9000 \
   -p 9090:9090 \
   --name minio \
   -v minio:/data \
   -e "MINIO_ROOT_USER=root" \
   -e "MINIO_ROOT_PASSWORD=mysecretpassword" \
   --restart always \
   quay.io/minio/minio server /data --console-address ":9090"

Create a new access key from http://127.0.0.1:9090/access-keys.

Update access and secret key from .env.

Run

# create database
python src/db_create_initial_data.py
# start server
python src/server_main.py
# start camera
python src/camera_main.py

Open server site: http://127.0.0.1:8000/site

Start the camera in dummy mode

python src/camera_main.py --dummy-mode True

Docker

Create network to connect containers

docker network create camera-network
docker network connect camera-network postgres
docker network connect camera-network minio

Change connections strings in .env file

# Use host name instead of IP address
SERVER_HOST="camera-server"
DB_CONNECTION="postgres://postgres:mysecretpassword@postgres:5432/camera_db"
MINIO_ENDPOINT="minio:9000"
# Change host ip and base path
UVICORN_HOST="0.0.0.0"
UVICORN_BASE_PATH="/app/src/"

Start containers

docker build -t camera-system .
docker run --name camera-server --network camera-network -p 8000:8000 --rm camera-system python src/server_main.py
docker run --name camera-camera --network camera-network --rm camera-system python src/camera_main.py --dummy-mode True
