dokku/logpond repository overview

⁠Logpond

A single-container log search service for Dokku hosts. Ingests JSON logs over HTTP, keeps recent logs hot for fast search and faceted browsing, and archives aged segments to S3 (or any destination you can script).

⁠Installation

Pull the multi-arch container image:

docker pull dokku/logpond:latest

Or deploy on Dokku in one step:

dokku git:from-image logpond dokku/logpond:latest

Pin a specific tag in production (dokku/logpond:v1.0.0 once cut) so an upstream release does not change behavior under you. Images are published to Docker Hub and signed with cosign keyless-OIDC against the GitHub workflow that built them. The full Dokku walk-through (storage mount, env vars, Vector sink, feedback-loop avoidance) is in docs/dokku-deployment.md⁠.

⁠Usage

Run Logpond locally with a minimal config:

mkdir -p /tmp/logpond-data
cat >/tmp/logpond.yaml <<'EOF'
data_dir: /tmp/logpond-data
sources:
  - name: default
    extract:
      timestamp: [timestamp]
      level: [level]
      message: [message]
      service: [service]
      host: [host]
EOF

docker run --rm -p 8080:8080 \
  -e LOGPOND_CONFIG=/etc/logpond/config.yaml \
  -v /tmp/logpond.yaml:/etc/logpond/config.yaml:ro \
  -v /tmp/logpond-data:/data \
  dokku/logpond:latest

Send a log event with curl:

curl -X POST http://localhost:8080/ingest/default \
  -H 'Content-Type: application/x-ndjson' \
  --data-binary $'{"timestamp":"2026-05-12T10:00:00Z","service":"api","level":"info","message":"hello"}\n'

Open http://localhost:8080/⁠ to search, browse facets, and live-tail.
