N8N

Para uso local do automatizador de fluxograma N8N, bem como containers do PGVector e do WAHA - WhatsApp API.

Baseado na configuração de deploy do N8N usando Docker.

docker network create my_n8n_network && \
docker volume create my_n8n_db && \
docker volume create my_n8n_data && \
docker volume create my_n8n_vector && \
docker volume create my_n8n_pgadmin && \
docker volume create my_n8n_waha && \
docker volume create --driver local --opt type=none --opt device=$(pwd)/backup --opt o=bind my_n8n_backup

Configuração das variáveis de ambiente:

cp .env.example .env

Subir a stack de containers:

docker compose up --force-recreate --build --remove-orphans --wait
