Room For Improvement

Users seek improved Docker on Ubuntu features: UI, networking, documentation, installation ease, security, storage, and orchestration integration.
Kali Linux requires user interface improvements, enhanced documentation, automatic updates, and expanded AI functionalities for increased usability and appeal.
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
Chief Technology Officer at ML Cloud LLC
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
Founder at Asynka
If real-time customized port scanning can be added, for example, instead of a default port such as 8080 or 443, if we can use a customized port such as 9876, that capability would be great.
Senior Technical Manager at a tech vendor with 10,001+ employees
I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
If there were video courses attached to how to safely use it, especially for absolute beginners with no previous experience using Linux operating systems, I think that could be very useful.

Featured Reviews

reviewer2795433 - PeerSpot reviewer
Cloud Ops Lead at a tech vendor with 10,001+ employees
Built a reliable cloud foundation that has supported flexible web applications and smooth scaling
Docker on Ubuntu can be improved because Ubuntu is not minimalist at all; it comes with a lot of software by default. This has led some individuals, including myself, to try using Alpine, which is more lightweight, allowing the container to run on a more lightweight operating system that potentially uses fewer resources and reduces costs. If Ubuntu were a little more minimalist, that would be good, but it's not really aiming for that since it intends to be the baseline. Also, Ubuntu moves very fast, possibly faster than other operating systems like Debian, which could demand operational heavy upgrades to major versions every couple of years if there are many applications running.

Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
