The official one Install Docker Engine on Fedora has precisely all the steps that you we need to get going.

You will get the following error. Simply because we have not started docker-compose service hence the postgres container is not up and running. You may want to start some of your containers at system boot.These are some of the applications that you use frequently and therefore you wish that everytime you are interacting with them, they are up and running!https://xbns.netlify.app/posts/2020-05-15-docker-postgresql/Wed, 13 May 2020 00:00:00 +0000https://xbns.netlify.app/posts/2020-05-15-docker-postgresql/You have succeeded in setting up docker engine in Fedora 32 and installing docker compose as well. Now it is time to install postgresql as a docker container. But first things first, Why install postgresql as a docker container rather than the usual popular way? Reasons for containerization of applications/databases. Software installation is quite chaotic especially if you have various versions running in your system. version clashes, upgrades and alot of productive time lost in this mundane task.https://xbns.netlify.app/posts/2020-05-05-change-icon-color-gimp/Tue, 05 May 2020 00:00:00 +0000https://xbns.netlify.app/posts/2020-05-05-change-icon-color-gimp/A while ago I wanted to change colored images and icons to black - white using gimp.
