We already covered how to get docker and download your Postgres container in your Mac, Windows or Linux computer. How To Invoke The Docker Postgres Container Docker Postgres Imageīasically this means the Postgres image is now ready to be used and spawned as a docker container and it was successfully pulled into your machine. Once the pul lis successful you should be able to see the docker Postgres image in your docker dashboard image registry as shown below. Status: Downloaded newer image for postgres:latest Once you register and login either from the dashboard which we showed earlier or from the command line using the following command:ĭigest: sha256:3e2eba0a6efbeb396e086c332c5a85be06997d2cf573d34794764625f405df4e This may require registration and an account in the docker hub which you can do online here. The first command we will be issuing is to download the Postgresql docker container from the docker repository. If you are in Linux or Windows you can use powershell or gnome-terminal to start invoking the commands we will demonstrate below. In order to do this we need to invoke a terminal application, I like to use iTerm2 but you can use the standard Mac terminal too. Now that we have successfully installed docker in our system we want to go ahead and fetch the postgresql docker container for our machine. Note you can ignore the container that I’m running above this will be shown at a later step once we get it running on your system. If you see the dashboard above it means docker is successfully installed in your system. This will bring up the user interface dashboard which is shown below. Once this is copied docker is successfully installed in your system and all you have to do is run it. For other variants you may need to run an installer which could also require a reboot, if it does I recommend you perform a reboot as well to be sure it starts properly. Once you download go ahead and do a quick install, on the Mac it’s simply copying over the executable file into your Applications folder as shown below. Navigate to the get docker url and download the flavor for Mac note the following guide can work on other machines too with slight adjustments so you can still follow it if you are using Windows or Linux. If you already have this setup you can skip to the next section below. The first thing you need to do to get started is to download the docker container in your machine. Now that we went over some of the reasoning of why it’s beneficial to run Postgresql in a Mac computer lets go over how you can get it running on your system. The list above even though it’s not as exhaustive it includes some of the reasons of why I like to run Postgresql in a docker container on my Mac. You are guaranteed version consistency in the future if something changes in postgres.You can easily snapshot your container and go back in time if needed to debug some issue.It’s easier to start/stop and completely turn off or relaunch the container if needed.It’s easier to isolate it from the rest of your system applications.Any third party dependencies such as postgresql extensions can be turned only once in your docker container.Your pipeline integration later will be a breeze as you’d have everything ready to go and prebundled.You can keep a standard setup and configuration that’s consistent across the board.Since it’s a docker container you can take with you and use it wherever you want.So our list below will be using those two points of reference when comparing things. Offcourse the alternatives is running it natively in your machine which is beyond the scope of this article or running it on an external server and just interacting with it. To make this more specific I have assembled a list below. This is a very valid question and the answer has various reasons some of which may or may not apply to you directly. You may find yourself what is the advantage of running Postgresql inside a docker container. We will go point by point on getting you up and running in less than 5mins, you do not need to have any programming knowledge to use the tools we are going to be using here. Since it’s a docker container it simplifies the process of bundling it up too. I have used this setup successfully in various projects and it works very well and have saved me a ton of time getting a database server without altering anything on my host machine. Today I will break this down in the following way: Today we will discuss How To Run Postgres In Docker On Mac (2022).ĭid you know that docker simplifies your Postgres setup?
