![]() ![]() INSERT INTO movies(id, title, release_year, genre, price) Now that our compose file is ready, we can create our SQL scripts file that must be copied in /docker-entrypoint-initdb.d/ - CREATE TYPE ![]() env file in your source folder and add all the environment variables, like below. The values which are in this form $ have been defined in an env file to be managed easily. Once you have created your docker file, now to run the Postgres container in a clean way, you can create a docker-compose.yml file. It will run any *.sql files, run any executable *.sh scripts, and source any non-executable *.sh scripts found in that directory to do further initialization before starting the service. You can add one or more *.sql, *.sql.gz, or *.sh after the entrypoint calls initdb to create the default Postgres user and database. This folder in your Postgres container is where you can add additional initialization scripts (creating the directory if necessary). Note that the line COPY below will copy all the sql files in our source folder, where we have our Dockerfile, and add them in the /docker-entrypoint-initdb.d/ COPY *.sql /docker-entrypoint-initdb.d/ LABEL description="Postgres Image for demo" Once the installation is complete, start your docker application and let’s jump into the tutorial.įirst, to start a Postgres database in a docker container, we have to create a Dockerfile. But It’s also available for Windows or Linux users. As I’m a Mac user, I installed docker on my Mac. To use docker, first you will need to install it. In this tutorial, I will show you how to set up a Postgres database under Docker. Well, Docker was invented to solve this type of problem, but also to facilitate the portability of systems and applications. Have you ever felt the burden of having to redo the same commands and the same configurations over and over again when changing workstations? On one, it works fine on the other, there are bugs you can't explain? Even though they are both the same version? Have you ever experienced that feeling of frustration when you have to install a database on two different machines?
