Running postgres in docker full#

In the end, I decided to try and run the Postgres process using Docker instead installing directly on Windows or dealing with a full VM. This kicked off a lot of searching on my part and didn’t find a good definitive answer on why that is or isn’t the way to do. This is the route I was going to at first, but in Rob’s book, he suggests using a VM for Postgres installation on Windows. On the download section of the official Postgres site, there is an option to download an installer. For personal projects SQL Server’s cost and be prohibitive and the release of Rob’s book added up to a good time to give PostgreSQL a try. I have a lot of experience using Microsoft’s SQL Server, but up until now, I haven’t touched PostgreSQL. But, your data is still save on your own computer.Over the weekend I finally got the chance to start reading A Curious Moon by Rob Conery which is a book on learning PostgreSQL by following the fictional Dee Yan as she is thrown into database administrator role at an aerospace startup. The container will be cleaned up and Postgres is gone again. If you’re done working, just CTRL-C out of your database.

Now, you can connect to localhost on port 5432, with default username postgres, password password and default database postgres.Ī great and easy way to connect to your database is with the TablePlus app (for Mac, Windows, Linux and more!):

“Delegated” means that the container’s view of the file system will be authoritative, as we won’t be changing the data from outside the container, so the database will be quick.

Sync all stored data of Postgres inside the container into our local folder /tmp/database (make sure this folder exists!).

Set the default password for the postgres user to password.

Allow connections to the Postgres inside the container on port 5432 from the outside of the container on port 5432.

Run a container and clean up afterwards and allow the process to be interactive (so you can cancel it when you’re done).

Start Postgres with Dockerĭocker run -rm -it \ -p 5432:5432 \ -e POSTGRES_PASSWORD =password \ -v /tmp/database:/var/lib/postgresql/data:delegated \ In my example, I’m going to write the database to my /tmp folder, but this can be anywhere.Ī better place would be a subfolder in your project, or in your home-dir.

Install Dockerįirst, make sure you have Docker installed on your computer: Create a local directory to persist the data in Let’s say I need to have Postgres in the specific (old) version 9.6 and the databases should be persisted outside the container on my local computer. You could make your own image that packs an operating system, your settings/preferences and your application into a container for easy deployment, but, you can also use a pre-build image to run things like a database engine! Run a local Postgres with Docker

→ What if I tell you, you can run Postgres in one command, in any version WITHOUT having to install it in your machine? WITH the benefit of persisting data? That would be a total game changer! 😃 Dockerĭocker allows you to put software in a container and run it with a single command. “What was the command again to stop/start the service?”, “Do you need to have it always be running in the background (even when you are not working)?”, “How to handle multiple versions next to each other?”, “How to handle updates?” But managing your local Postgres is a real pain. by using the the installer, homebrew or postgres.app. However, there are various ways in which you can install PostgreSQL on your machine, e.g. Postgres is a great database server that you can install locally on your computer for development.
