Hello everyone, I started doing some tryouts on Openshift for internal use at my employer. I come from a Kubernetes background, runing on cloud providers (such as AWS)
Since we will be using our own infrastructure for now on, I started investigating Openshift, since it bring the polices, seggration, and support for distribuited storage such as glusterfs. I managed to an small 1 master and 3 nodes openshift cluster (1 etcd, no glusterfs), using openshift-ansible I did get it going. I do like the fact that it uses ansible for orchestration, its a widely know tool with lots of documetation. After fidling a little bit with the plaftorm I am getting some intial questions that hope you can enlighten me: 1. After an instalation process is finished its seems that the web console is faily limited to only showing the examples of applications to deploy, I get no "administritative" section, like in the kubernetes admin web interface, I would like to at least see the general resources of my cluster. Like overall CPU, RAM, and storage in my cluster. Am I missing something, or do I need to get a prometheus going? 2. Is is possible to install the default kubernetes web interface? 3. There is no centralized logging, do I need to install an ELK stack afterwards? 4. Is it possible to add glusterfs to an already running cluster without distruibuted storage? Regards, Alfredo Palhares
