I did not ssh or exec into the Docker image Tutorial are run from the shell of the host system, i.e. Notes Throughout this post, I’ll shorten PostgreSQL to postgres. Using fish, but the following instructions are given with Bourne-again Utilities, including createdb, which I use in the middle of this tutorial. I’m usingĪlso installed PostgreSQL using brew install postgresql, which puts a suite of command line Prerequisites I’m going to assume you have a modern version of docker running. ![]() Preloaded with your own database and pushing it back to DockerHub for redistribution. This blog post is about preparing a derivative of the base PostgreSQL Docker image that’s However, it’s not so straightforward to pre-load your ownĭata. In Docker this is known as a volume.PostgreSQL is a powerful relational database management system thatĬan be easily downloaded and installed from Firstly we need to create the persistent storage. Let’s start building a “real world” Postgres container. To make it accessible we need to forward a host operating system port to the container port. A database is no use if it can’t be accessed. Port forwarding from host to container: The container network is isolated, making it inaccessible from the outside world.To be a working database, we need to add a persistent filesystem to the container. This is not suitable for database systems. What this means is whenever we restart a terminated or deleted container, it will get an all-new, fresh filesystem and all previous data will be wiped clean. Persistent storage: By default the container filesystem is ephemeral.We will add 2 more features to make it useable: It requires more features to be able to serve as a working database for a real world application. The basic Postgres container is only good for learning or testing. Run Postgres image as a “real world” Postgres container The following command is the bare minimum for running Postgres on Docker: Run the Postgres image as a basic Postgres container This is essential information for starting a Docker image, as we will see in the following steps. From this page we know the image name and the required parameters. The page that search result links to describes the Postgres image, how it was made and how to use it. This is the image maintained by the Docker PostgreSQL Community. If you don’t have any special requirements, it is best to select the official image. There are a lot of images for PostgreSQL at Docker Hub. Go to Docker Hub and search for “postgres”. ![]() A decent text editor, such as Vim or Notepad++, to create the configuration YAML files. ![]() Internet access is required to pull or download the Postgres container image from the Docker Hub.Please refer to my previous article for help with Docker installation. It is officially supported on all the major operating systems: Windows, Linux, BSD, MacOS, and others.īesides running as an executable binary in an operating system, Postgres is able to run as a containerized application on Docker! In this article we are going to walk through the Postgres implementation on Docker. PostgreSQL, or Postgres, is an open-source relational database. ![]()
