Docker

Docker

Container images for sidecar and standalone deployments are published to Docker Hub (linux/amd64, linux/arm64).

docker compose up --build          # local smoke test (file sink, no filter)
docker compose -f docker-compose.smoke.yaml up --build   # filter smoke (see below)
docker compose -f docker-compose.kafka.yaml up --build   # Kafka round-trip (see below)
docker pull sanjuthomas/log-forwarder:latest

Filter smoke test (file sink)

Round-trip test with an ERROR-only filter: INFO/WARN lines are dropped, one ERROR record lands in JSONL, and /metrics exposes log_forwarder_lines_filtered.

./scripts/docker-smoke.sh

Uses docker-compose.smoke.yaml and configs/example-docker-filter.yaml.

Kafka smoke test

Round-trip test: forwarder → Kafka topic → consumer verifies JSON. The smoke config applies an ERROR-only filter (WARN lines are dropped).

./scripts/kafka-smoke.sh

Uses docker-compose.kafka.yaml (Apache Kafka KRaft + topic init + forwarder). Requires Docker Compose v2 with compose up --wait.

GitHub Actions: Kafka smoke runs on every pull request to main (required check before merge).

See docs/docker.md for volume mounts, Kubernetes sidecar notes, and maintainer publish steps.
