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
It is based on customer requirements, as they might want to use Rocky Linux or Ubuntu, depending on their needs.
System Engineer at clusterkit
Rocky Linux could be improved by having more integration with Kubernetes.

Featured Reviews

AnilKumar13 - PeerSpot reviewer
Devops Engineer at EDAG
Containerization has streamlined testing workflows and reduces server resources for our builds
The best features that Docker on Ubuntu offers in my experience are ease of usability and performance. Ease of usability and performance with Docker on Ubuntu have helped me because Ubuntu is a Debian-based OS that can operate in both server and desktop modes, so when using Docker on Ubuntu on a server base, I need to install a few packages to convert the machine to GUI mode, making Docker on Ubuntu easy to use. While I think security is not a standout feature, ease of usability and performance remain the main highlights for me since it's only environment-specific and involves local testing along with monitoring only internal servers. Docker on Ubuntu has positively impacted my organization through resource savings, as for our NOC server, we are using a dedicated 30-core server with 256 GB of RAM, but with the help of Docker on Ubuntu, we can run multiple containers on the same server. In terms of resource savings, we reduced the number of servers from around 100 to 70 after using Docker on Ubuntu within our private cloud, where we have numerous servers located in multiple locations in the US.
Massimiliano Adamo - PeerSpot reviewer
Linux architect at European Commission
Has supported seamless migrations and enabled running complex data workloads securely
The best features Rocky Linux offers include clustering and all the packages from Red Hat.Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux. Everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe. Rocky Linux is very good for security and other aspects. Since migrating to Rocky Linux, I've seen specific outcomes such as improved security because CentOS stopped the project, and security patches aren't being released. We need to maintain a system similar to Red Hat, which is very stable and has many features such as file system, topology, and containers.
