There is a CoreOS user forum available also on the #Coseos IRC channel.Дocker also has versatile community support because of its huge number of users. They have versatile documentation support as well. In docker, to have advanced capabilities, docker data centre solutions provide enterprise container orchestration or graded security feature or enhanced application management.Д«ecause of its popularity and dominance, RKT has developed a strong user and open-source developer community where most of the questions get cleared. Rcketr or RKT is more security-focused container solutions it is an open-source lightweight Linux OS on top of the Linux kernel. In the container platform, docker and rkt are dominant players, and both vendors have shown dominance by highlighting individual features. Docker Engine API is also a restful API that can be accessed by an HTTP client such as curl or weget. The SDKs can allow us to scale and build docker applications quickly and easily. There is an API for interacting with Docker daemon as well as SDKs for GO and Python known as Docker Engine API. The API service which is used is optional for running pods the start or stop or crash of API wonвЂ™t affect any pods or even images. The API services used by RKT are designed to run without root privileges and has a read-only interface. GRPC is the API used by CoreOS, a high performing, open-source and universal framework. The table below summarizes the comparisons between RKTВ vs Docker :Д¬oreOS provides a tectonic platform that allows the visual management of containers and provides better ease of use.Дocker also has a GUI based manager for managing docker containers and is known as Kitematic. In RKT, new containers will never be created from the root privileged process, and thus even if container breakout happens, the attacker will not be able to get root privileges.

Docker runs its containers from the root, and this will be the superuser privilege, and many server owners feel that this can complicate things.

This drawback with docker has some relief with some added security feature, but it is not as secure as RKT.

But in RKT, signature verifications are done, so as soon as the server image is downloaded, it will check with the signature to validate if it has tampered. Thus there will be the possibility that server image can be replaced with malware one, and this will be huge isolation. In Docker, there will be a public image registry that can be downloaded and customized. Another major difference would be with container image security.Thus, we will have an active monitoring initiative that ensures that we can restart the process when more than once processed are sharing the same container. Since Rocket is an app container runtime, another major difference would be Rocket can run multiple applications inside the container unless the docker.

Still, there is the feasibility to run on macOS and windows as well. Whereas Docker daemon is the service that will be running on the host operating system and this particular daemon runs on Linux. Rocket does not have any daemon associated with it, so when the user runs вЂњrocket run coreos/etcdвЂќ, it is directly executing under the process that started it.

The main key difference between RKT and Docker will be a daemon.

Let us discuss some key differences between RKTВ vs Docker in the following points:

Rkt, which is Rocket, is known for its fast, composable and secure providing feature. RKT is more knows as an вЂњapp container at run timeвЂќ among the developers and is a CLI based application container.

Docker is created as part of the open-source project in 2013 and has garnished instant fame because of the features isolation, Rapid integration and build-up, reproducibility and testability, etc. Docker is a leading container-based platform that supports continuous high-velocity innovation enabling multiple organizations to seamlessly build process and share applications which can be even legacy ones. RKT(rocket) vs Docker Both are popularly known among developers who work on virtual machines and container-based platforms.
