In my previous blogpost I installed Portainer in Docker Compose. It’s a great graphical user interface for managing Docker containers and images. While exploring Portainer I noticed something strange: I had a lot of unused images! What happened?
This is my story of how I reclaimed almost 200GB of data, just from deleting unused Docker images.
What are Unused Docker Images? There are a few scenario’s when a Docker image can be unused.
Managing your docker containers can be quite a hassle. Creating, updating and monitoring in the terminal is not very intuitive and the lack of visualization makes it very difficult to see what is going on. Fortunately there is a solution and it’s called Portainer. It’s a docker management interface where you can perform a lot of common tasks very easily from the comfort of your browser. Let’s install Portainer!
Installing Portainer Using Docker Compose For those who have read my other blogposts: I love Docker Compose: it’s easy to read and because it’s just a file, it is also very easy to move to another server and get up and running in no time.
Transmission is a very lightweight and simple to use torrent client. It support a lot of great features and works on many many systems. All that is great, but the real reason why I love Transmission as much as I do, is because of it’s great web interface. It’s really fast, works on all modern browsers and operating systems and you don’t even need to install the client on every computer!
