And look at the size of this image, it’s just around 150MB, pretty small. Now if we run docker images, we can see the postgres image right here. You can apply it to download any other images of any version you want.Īlright, the image is successfully downloaded. We use a : to separate the image name and its tag (or version). The syntax to pull an image is docker pull. Thanks to the light-weight alpine linux distribution.Įnter fullscreen mode Exit fullscreen mode I often use alpine image, since its size is very small. There are many other versions with different tags as well. This will pull the image with the latest tag.

But we’re gonna use the first one, because it is the official Postgres image.Īs you can see here, we can simply run docker pull postgres to get this image. So let’s go to Docker Hub to search for its image. In this course, we will use PostgreSQL as the database engine for our app.

So let’s learn how to pull the first image. If we run docker images to list all available docker images. At the moment it’s an empty list because we haven’t run any containers yet. We use docker ps command to list all running containers. When the circle turns green, we know that docker desktop is started and ready to be used. Right now it’s a yellow circle, which means docker desktop is still starting. Let's open the app! It will take a while for docker desktop to start, you can see its status by clicking on this icon. And that’s it! Docker desktop is successfully installed. On a Mac, it’s super easy! We just need to open this docker website and click download.Īfter the installer is downloaded, we open it, and drag Docker into the Applications folder.

Here's the link to the full series playlist on YoutubeĪlright, let’s start by installing docker. We will also learn how to setup and use TablePlus to connect and interact with Postgres, and use it to run the SQL script that we’ve generated in the previous lecture to create our Simple Bank’s database schema. Today we will learn how to install Docker Desktop on local machine, then download and start a PostgreSQL container. In the last lecture, we’ve learn how to design a database schema with dbdiagram.io Welcome back to the backend master class!
