Breaking Changes

Redis Schema Migration Required

Existing deployments must migrate Redis keys to hash-tagged format before upgrading to v0.6.0. This enables Redis Cluster support for horizontal scaling.

Schema Change

The Redis key structure has been updated to support Redis Cluster by adding hash tags:

Why?

Redis Cluster distributes keys across nodes using hash slots. Without hash tags, related keys like tenant:123 and tenant:123:destinations could be on different nodes, causing CROSSSLOT errors during transactions. Hash tags {...} ensure all tenant data maps to the same hash slot, enabling atomic multi-key operations.

outpost binary behavior change

The outpost binary is now a unified CLI that consolidates server and migration operations.
The binary interface has changed:

Before v0.6.0:

outpost # Start the server

v0.6.0 and later:

outpost serve    # Start the server
outpost migrate  # Run migrations
outpost --version

• Docker service users (e.g., docker-compose up) - No changes required. The container
  still starts the server by default.
• Docker CLI users (e.g., docker run hookdeck/outpost ...) - The entrypoint is now the
  unified CLI, so commands change as shown above.
• Binary users - Update scripts/commands to use outpost serve instead of outpost.
  • NOTE: The outpost CLI orchestrates outpost-server and
    outpost-migrate-redis binaries. All three binaries must be in the same directory or
    available in your $PATH for the CLI to function correctly.

Migration Steps

Option 1: Using environment variables

docker run --rm \\
  -e REDIS_HOST=your-host \\
  -e REDIS_PASSWORD=your-password \\
  hookdeck/outpost:v0.6.0 migrate plan

Option 2: Using CLI flags

docker run --rm hookdeck/outpost:v0.6.0 migrate plan \\
  --redis-host=your-host \\
  --redis-password=your-password

Option 3: Using .env file

docker run --rm --env-file .env hookdeck/outpost:v0.6.0 migrate plan

Then proceed with apply, verify, deploy, and cleanup:

docker run --rm -it hookdeck/outpost:v0.6.0 migrate apply [options]
docker run --rm hookdeck/outpost:v0.6.0 migrate verify [options]
# Deploy v0.6.0 and test thoroughly
docker run --rm -it hookdeck/outpost:v0.6.0 migrate cleanup [options]
