Upgrading from v0.9.0 to v0.10.0 takes some care as it includes changes to the underlying ClickHouse schema. This guide will walk you through the necessary steps to upgrade your existing installation.

​
Step 1: Setting Up Your docker-compose.lite.yaml File

First, add the environment variable BOOTSTRAP: "false" to your docker-compose.lite.yaml file. This will prevent your lite instance from running bootstrap operations when it restarts. Next, make sure you have an admin-cli instance specified in our docker-compose.lite.yaml file. We’ll be using this service to run the upgrade scripts. Your docker-compose.lite.yaml file should look something like this: 
...
services:
  lite:
    image: dittofeed/dittofeed-lite:${IMAGE_TAG:-v0.9.0}
    restart: always
    ports:
      - "3000:3000"
    depends_on:
      - postgres
      - temporal
      - clickhouse-server
    environment:
      <<: *backend-app-env
      # uncomment while upgrading dittofeed
      BOOTSTRAP: "false"
    env_file:
      - .env
    networks:
      - dittofeed-network-lite
  # useful for upgrading dittofeed
  admin-cli:
    image: dittofeed/dittofeed-lite:${IMAGE_TAG:-v0.10.0}
    entrypoint: []
    profiles: ["admin-cli"]
    command: tail -f /dev/null
    tty: true
    depends_on:
      - postgres
      - temporal
      - clickhouse-server
    environment:
      <<: *backend-app-env
    env_file:
      - .env
    networks:
      - dittofeed-network-lite
...

​
Step 2: Start the admin-cli Service

Next, run the following command to start your admin-cli service: 
docker compose --profile admin-cli -f docker-compose.lite.yaml up admin-cli -d

​
Step 3: Run the Pre-Upgrade Script

Then run the following command to run the pre-upgrade script: 
./scripts/admin-lite.sh upgrade-0-10-0-pre

​
Step 4: Upgrade Your docker-compose.lite.yaml File

Upgrade the version in your docker-compose.lite.yaml file to v0.10.0: 
...
services:
  lite:
    image: dittofeed/dittofeed-lite:${IMAGE_TAG:-v0.10.0}
...
Now restart your lite instance: 
docker compose -f docker-compose.lite.yaml up lite -d --force-recreate

​
Step 5: Run the Post-Upgrade Script

Finally, run the post-upgrade script: 
./scripts/admin-lite.sh upgrade-0-10-0-post
And stop the admin-cli service: 
docker compose --profile admin-cli -f docker-compose.lite.yaml stop admin-cli
