We use the tool to manage and secure the event file system. CoreOS Clair is an operational system that is very similar to Linux and offers benefits to other Linux operating systems. One major advantage of using OpenShift is that you don't need to pay for CoreOS.
What is our primary use case?
How has it helped my organization?
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.
What is most valuable?
The user interface is good, the operational system activity is satisfactory, availability is very reliable, and security is robust. CoreOS Clair can integrate with CI/CD features like GitLab and Argo CD.
What needs improvement?
It can be improved in its support response. They usually take up to seven days to resolve the issue.
For how long have I used the solution?
I have been using CoreOS Clair for ten years.
What do I think about the stability of the solution?
I rate the solution’s stability a nine out of ten.
What do I think about the scalability of the solution?
The solution’s scalability is good.
I rate the solution’s scalability a nine out of ten.
How was the initial setup?
The initial setup is easy.
What's my experience with pricing, setup cost, and licensing?
If you work with CoreOS or OpenShift, you don't need to pay for CoreOS separately. When you pay for OpenShift, you get CoreOS included, so you don't need to pay for the operating system separately. Essentially, with OpenShift, the cost of the operating system, like CoreOS, is covered. You only pay for what you use with OpenShift, including control planes such as the infrastructure and master nodes. All applications that use CoreOS are covered under the OpenShift subscription, providing a cost-effective solution.
For those using Enterprise Linux for servers or data centers, the pricing structure for CoreOS Clair may vary.
What other advice do I have?
Support for CentOS ended in June, and many customers are migrating their operating systems to Enterprise Linux CoreOS. Customers installing OpenShift need to have Enterprise Linux CoreOS inside OpenShift. If you have other subscriptions for SUSE Linux, people are migrating these subscriptions to CoreOS.
It is a security solution that ensures compliance.
If you're working with CoreOS, you will take your application and use it inside a container. Containers provide many security features. Your container will be isolated, reducing the risk of security breaches. With CoreOS Clair, you can also scan your container images for vulnerabilities, enhancing the overall security of your system.
Overall, I rate the solution a nine out of ten.
