Error in Dokploy

Hi all,

after trying to install tianji I failed hard. I use dokploy to run the containers. I have no clue what I'm doing wrong. Hope you guys can help.

docker-compose.yaml

services:
  tianji:
    image: moonrailgun/tianji:1.19.5
    environment:
      DATABASE_URL: postgresql://tianji:tianji@postgres:5432/tianji?connect_timeout=300&pool_timeout=300
      ALLOW_REGISTER: "false"
      ALLOW_OPENAPI: "true"
      JWT_SECRET: "something"
      OPENAI_API_KEY: "something"
    depends_on:
      postgres:
        condition: service_healthy
    restart: always
  postgres:
    image: postgres:15.4-alpine
    environment:
      POSTGRES_DB: tianji
      POSTGRES_USER: tianji
      POSTGRES_PASSWORD: tianji
      POSTGRES_HOST_AUTH_METHOD: trust
      PGDATA: /var/lib/postgresql/data/pgdata
    volumes:
      - tianji-db-data:/var/lib/postgresql/data
    restart: always
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U $${POSTGRES_USER} -d $${POSTGRES_DB}"]
      interval: 5s
      timeout: 5s
      retries: 5

volumes:
  tianji-db-data:

Even my network looks good:

Thank you and best regards

Start with docker-compose.yaml and the PostgreSQL container's health and logs; then inspect src/server/prisma/schema.prisma and the migration command shown in the startup output. Reproduce the deployment and identify why the tianji container cannot reach postgres:5432; done means a documented configuration or confirmed application fix, with migrations completing.
