+# Fluent Bit Log Hashing Example
+
+This lab demonstrates how to use Fluent Bit to process log lines, generate a hash for each log entry, and output the results. This is useful for anonymizing or deduplicating logs, especially in Kubernetes environments where logs are persisted in `/var/log/containers/*.log`.
+
+```bash
+├── docker-compose.yml      # Runs Fluent Bit in a container using the provided configuration.
+├── fluent-bit.yaml         # Fluent Bit pipeline configuration
+└── hash-process-sample.py  # Python script that demonstrates how to hash a log line using SHA-256, matching the logic in the Fluent Bit pipeline.
+```
+
+## Running the Lab
+
+```sh
+docker compose up --watch
+```
+
+You should see output similar to:
+
+```json
+{"message":"2025-06-19T17:02:35.123456789Z stdout F This is a Foobar application log sample running in kubernetes persisted on /var/log/containers/*.log","_id":"19a93f55808eb5478c65813c028045f1b354abe12790eb8aee0dd825697aa93e"}
+```
+
+## Hash Verification
+
+You can verify the hash using the provided Python script:
+
+```sh
+python3 hash-process-sample.py
+```
+
+The output should match the `_id` field in the Fluent Bit output.
