gramal/postgres-exporter repository overview

⁠Postgres exporter image

This image overrides the default image postgres-exporter⁠ and adds support for setting postgres exporter arguments (that do not support it) via environment variables

⁠Running

All collector arguments can be set via env variables adding PG_EXPORTER_COLLECTOR_ prefix. For example

--collector.database ( PG_EXPORTER_COLLECTOR_DATABASE=true)
--no-collector.database ( PG_EXPORTER_COLLECTOR_DATABASE=false)
--collector.replication_slot (PG_EXPORTER_COLLECTOR_REPLICATION_SLOT=true)
--no-collector.replication_slot (PG_EXPORTER_COLLECTOR_REPLICATION_SLOT=false)

Plus you can set --web.listen-address using PG_EXPORTER_WEB_LISTEN_ADDRESS=9111

docker example

docker run --rm -e PG_EXPORTER_COLLECTOR_REPLICATION_SLOT=true -e PG_EXPORTER_WEB_LISTEN_ADDRESS=9111 gramal/postgres-exporter:latest

⁠Why this is needed?

We use postgres-operator from zalando and currently it does not support adding arguments to configured sidecars⁠. So in order to add different cmd line options to postgres-exporter we use this image that enables setting cmd line args through env vars
