This images is built from the official postgres docker image, but with
updates to optimize the test execution:
- A config file for postgres to increase the performance of the
test server.
- An initialization script to create a template database with all
migrations run against it.
There are new make targets to build and publish this docker image.
The image can be pulled with:
docker pull hashicorpboundary/postgres:13-alpine
To use this image for tests start the container:
make -C internal/db/docker database-up
