+  "database": {
+    "url": "jdbc:postgresql://booru_grabber_postgres:5432/test",

+  "database": {
+    "url": "jdbc:postgresql://booru_grabber_postgres:5432/test",
+    "driver": "org.postgresql.Driver",
+    "username": "test",
+    "password": "test",
+    "reconnectOptions": {
+      "attempts": 3,
+      "delay": 1000
+    }
+  },
+  "client": {
+    "connectionTimeoutMillis": null,
+    "requestTimeoutMillis": null,
+    "responseTimeoutMillis": null,
+    "proxy": {
+      "hostname": "proxy.example.com",
+      "type": "socks",
+      "port": 1080,

+    image: postgres
+    container_name: "booru_grabber_postgres"
+    environment:
+      POSTGRES_USER: "test"
+      POSTGRES_PASSWORD: "test"
+      POSTGRES_DB: "test"
+  booru_grabber_bot:
+    image: insanusmokrassar/booru_grabber_bot
+    container_name: "booru_grabber_bot"
+    volumes:
+      - "/absolute/path/to/config.json:/booru_grabber_bot/config.json:ro"
