Assuming there is a PostgreSQL server running with a user postgres and an empty database postgresl:

POSTGRES_HOST=<postgresql-host> POSTGRES_USERNAME=<postgresql-username> POSTGRES_PASSWORD=<postgresl-password> go run main.go

Docker

Build

docker image build -t smpl-go-pg:0.2.0 .

Tag

docker image tag smpl-go-pg:0.2.0 fischerjulian/smpl-go-pg:0.2.0

Publish to Registry

docker image push fischerjulian/smpl-go-pg:0.2.0                                   

Pull Image from Registry

docker image pull fischerjulian/smpl-go-pg:0.2.0

In order to run the image you will also have to set the env vars POSTGRES_HOST and POSTGRES_PASSWORD which is not contained in the examples below as the images will be used in the context of Kubernetes, only.

Run local image with version tag 0.2.0:

docker container run -p 8080:8080 smpl-go-pg:0.2.0

Run remote image with version tag 0.2.0:
