How to run PostgreSQL inside a Docker container

I showcase how we can create a docker container running a PostgreSQL Database. We then add some SQL to the database, and go into the container to access the database to check everything works as intended. Dockerfile: FROM postgres ENV POSTGRES_PASSWORD docker ENV POSTGRES_DB user COPY /docker-entrypoint-initdb.d/ Commands: Build docker image: docker build -t dbpost . Run doker contianer from image: docker run -d --name my-postgresdb-container -p 5432:5432 dbpost Get into the docker container: docker exec -it [container id] /bin/bash Get into postgreSQL: psql -U postgress My channel publishes programming and software engineering videos, especially Java and Python.
