An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Consistently maintains vulnerability-free images and integrates effectively with builds
Trivy is very reliable and always has an up-to-date database to scan images and identify vulnerabilities. I integrated it with Jenkins jobs, so every time we run a build, if there is a high, critical, or medium vulnerability, the build is set to fail. This ensures that somebody resolves the issues before the code progresses. This approach helps keep every image in every project we work on vulnerability-free.

Pros

"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"CoreOS Clair's best feature is detection accuracy."
"The most valuable feature of Trivy is its easy integration with the CI/CD pipeline."
"Trivy is easy to integrate with CI/CD and can be installed on desktops to scan images."
"The vulnerability scanning feature is excellent as it supports various container capabilities like Docker and Sharma."
"I can see vulnerabilities in the images of any applications deployed in the Kubernetes environment or as container applications."
"It is open-source."
"One of the great features of Trivy is that it helps me scan items such as AWS credentials and GCP service accounts."
"Trivy is most valuable for its ability to scan all repository files and dependencies."
"Trivy is very reliable and always has an up-to-date database to scan images and identify vulnerabilities."
 

Cons

"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"Trivy generates many false positives, flagging non-existent vulnerabilities."
"In our CI/CD pipelines, Trivy lacks built-in functionality for report analysis."
"Trivy is not scalable; however, I have scanned very large projects with it. It is stable but not scalable according to my experience."
"The reporting could be a little better."
"The reporting could be a little better. When integrating Trivy with CI, the interpretation of the reports could be improved."
"One drawback I have observed with Trivy is the difficulty in building or integrating a UI, particularly for an operator in the NetSuite example."
"For malware detection, I need to use two tools: Trivy as my anomaly scanner and ClamAV. I am integrating these two tools into the CI pipeline. If both malware and anomaly detection could be managed by one tool, I would not need to depend on two tools. That would be my suggestion."
"A dynamic scanning capability during runtime would be a significant advantage."
