PeerDB-Server Overview

Secure your stack with a hardened PeerDB-Server image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies.

PeerDB-Server is a Postgres-first ETL tool designed to orchestrate fast and scalable data replication from PostgreSQL to target destinations like data warehouses, queues, and storage engines.

Try It Out

Take the Minimus PeerDB-Server image for a test run. PeerDB provides an official Docker Compose file that handles all dependency orchestration (Postgres catalog, Temporal, Flow-API, Flow-Worker). The steps below use that upstream setup with Minimus images swapped in.

To begin, log into the Minimus registry:

echo "{token}" | docker login reg.mini.dev -u minimus --password-stdin

Clone and Override

Clone the PeerDB repository and create an override file that points to hardened Minimus images:

git clone --depth 1 https://github.com/PeerDB-io/peerdb.git
cd peerdb

Save the following to docker-compose.override.yml:

services:
  catalog:
    image: reg.mini.dev/postgres:latest
  temporal-admin-tools:
    # The upstream mounts a custom entrypoint script and uses the now 
    # deprecated tctl for its healthcheck. Clearing the
    # entrypoint restores the image's built-in CMD, and the healthcheck is
    # replaced with the Temporal CLI.
    image: reg.mini.dev/temporal-admin-tools
    entrypoint: []
    healthcheck:
      test: ["CMD", "temporal", "operator", "cluster", "health", "--address", "temporal:7233"]
      interval: 5s
      timeout: 5s
      retries: 30
      start_period: 45s
  temporal-ui:
    image: reg.mini.dev/temporal-ui
  flow-worker:
    image: reg.mini.dev/peerdb-flow-worker
  flow-snapshot-worker:
    image: reg.mini.dev/peerdb-snapshot-worker
  flow-api:
    image: reg.mini.dev/peerdb-flow-api
  peerdb:
    image: reg.mini.dev/peerdb-server
  peerdb-ui:
    image: reg.mini.dev/peerdb-ui

Print the resolved image list to verify the images:

docker compose config | grep "image:"

Note that Docker Compose will only auto-discover the override file if it is named exactly docker-compose.override.yml or docker-compose.override.yaml. Otherwise you will need to explicitly pass the file names like so:

docker compose -f docker-compose.yml -f my-docker-compose.override.yaml config | grep "image:"

Start the Services

docker compose up -d

Wait for all services to become healthy:

docker compose ps -a

Verify PeerDB-Server

Once the services are running, confirm PeerDB-Server has started and is accepting connections:

docker compose logs peerdb | grep "Listening on"

Clean Up

docker compose down -v

Technical Considerations

The PeerDB-Server image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

PeerDB-Server built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
