Since there are issues with collations in the default alpine-based timescaledb images, I tried to use the bitnami-image. But I get an error on startup.

docker run ^
-p 5432:5432 ^
-v tsdb-bitnami:/bitnami/postgresql ^
--env POSTGRES_USER=tsdbu ^
--env POSTGRES_DB=tsdbu ^
--name timeseriesdb ^

This fails with:

ERROR:  permission denied to create extension "timescaledb"
HINT:  Must be superuser to create this extension.

Is there some other parameter that we must pass? i.e. I've tried POSTGRESQL_POSTGRES_PASSWORD (ref= bitnami postgres docs), but this did also not work.

  • "It is possible to change the user that PostgreSQL will use to execute the init scripts. To do so, use the following environment variables" -- that maybe? – Philᵀᴹ Nov 6 '19 at 12:54

    The POSTGRES_USER is documented by bitname to be a regular user, which indeed cannot install timescaledb. github.com/bitnami/… As a workaround for now, specify POSTGRES_USER to be postgres, that will work, afterwards you can create a database and user manually. Created an issue to have this addressed here: github.com/timescale/timescaledb-docker/issues/79 – Feike Steenbergen Nov 6 '19 at 13:03
