docker compose down
docker compose rm -f

The docker compose file contains the following components:

• vector - vector is configured to collect logs from the docker, you can find configuration in the vector.yaml. It writes data in two instances of VictoriaLogs
• VictoriaLogs - the two instances of log database, they accept the data from vector by json line protocol
• vmauth - load balancer for proxying requests to one of VictoriaLogs

Querying the data

• vmui - a web UI is accessible by http://localhost:8427/select/vmui/
• for querying the data via command-line please check these docs
