Summary

I am deploying this compose file:

services:
  # PostgreSQL Database for Shlink
  shlink_db:
    image: postgres:16.4-alpine
    container_name: shlink_db
    restart: unless-stopped
    environment:
      POSTGRES_USER: shlink_user
      POSTGRES_PASSWORD: ${DB_PASSWORD}
      POSTGRES_DB: shlink_db
    volumes:
      - /docker_backup/shlink/postgres-data:/var/lib/postgresql/data
    networks:
      - proxy_network
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U shlink_user -d shlink_db"]
      interval: 10s
      timeout: 5s
      retries: 5

  # Shlink URL Shortener
  shlink:
    image: shlinkio/shlink:stable
    container_name: shlink
    restart: unless-stopped
    depends_on:
      shlink_db:
        condition: service_healthy
    env_file:
      - .env
    networks:
      - proxy_network

  # Shlink Web Client (UI)
  shlink-web-client:
    image: shlinkio/shlink-web-client:stable
    container_name: shlink-web-client
    restart: unless-stopped
    env_file:
      - .env
    networks:
      - proxy_network

networks:
  proxy_network:
    external: true

Everything is working great, except that when I set a colour for a Tag, this gets lost and reverted to a random colour after the container is restarted.

What am I doing wrong?

Tag colors are not saved in Shlink's database, but handled by Shlink Web Client in the browser's local storage.

That means that they can be gone if you use an incognito session, clear the local storage or use different devices.

You can use Shlink Dashboard if you need that to be persisted server-side. In there, tag colors are saved in the dashboard's database and linked to the user account, so you will see the same colors regardless the device or type of navigation.
