Previously, we maintained OpenShift templates for deploying apps in development environments as well as delivering these templates to our customers for their on-prem deployment. Customers who refer to our templates (as well as documentation) have their own configuration management tools to automate the deployment such as ArgoCD and FluxCD. My son's buildings Our developers usually modify templates (YAML) directly on OpenShift for testing and then adjust the corresponding templates stored in the Git repository in Bitbucket. This sometimes causes an issue that delivered templates are incorrect because: - Developers forget to update the templates in Git repositories. - Developers don’t test the templates Therefore, our goal was to integrate a tool into our CI/CD that can automate and manage the configuration of OpenShift apps. The delivered templates should be the ones that are able to run on our OpenShift with the following purposes: - Automate deployment from templated in Git repos

I have recently been trying to use PSMDB (Percona Server for MongoDB) as an open-source and free alternative for MongoDB Enterprise Server. I encountered an issue that the pod could not be initialized successfully with Persistent Volumes using NFS shares. I got the logs from the failed pod as follow: ------ ++ id -u ++ id -g + install -o 1000730000 -g 0 -m 0755 -D /ps-entry.sh /data/db/ps-entry.sh install: cannot change ownership of '/data/db/ps-entry.sh': Operation not permitted ---- I would like to share the steps how I used for debugging. The PSMD StatefulSet was deployed onto my OpenShift 3 OKD. Check the container mount info Go to a pod I could see the mount info as below mongod-data → /data/db read-write - mongod-data: Persistent volume claim name - /data/db: container mounted directory Check Persistent volume binding Go to the storage, I could know which persistent volume was bound to the corresponding persistent volume claim. Bound to volume psmdb-mongodb-data-0 Check P

Encryption is the most popular tool for securing data both in transit and at rest. - For protecting data in transit, we can configure to use the TLS connection - For protecting data at rest, we can use Percona Server for MongoDB (PSMDB), an open-source alternative for MongoDB Enterprise. License PSMDB Docker images follow the SSPL license. Therefore, it is not a problem when I only have my containers deployed in on-premises environments. Running MongoDB Replication on OpenShift I have successfully installed the replication by following the guide Install Percona Server for MongoDB on OpenShift . In order to make it work properly with my needs, I disabled some features from the default deployment. See the detail in this change Basically, I needed to create a CRD (Custom Resource Definition) to let OpenShift/Kubernetes what PSMDB is. Then, I deployed the Operator pod. Finally, I deployed the PSMDB StatefulSet. I used NFS shares for Persistent Volumes. Create CRD for PSMDB 2 git clone http
