Develop applications
- Rancher desktop based on k3s. It is the best way to run the local kubernetes environments
Operate clusters
- kubectl is the default tool that can be extended by plugins
Manage third party applications

In clusters
Syncronize desired state with the actual state
GitOps can be also achieved by pipelines. Both of them are great. You’ll just have process in your cluster and continiously monitor your git repository and whenever it detects the change in git repository, than it will update the state of your kubernetes resources
- argocd is a declarative, GitOps continuous delivery tool for Kubernetes
- flux - another GitOps for apps and infrastructure
Encryption
TLS certificates
- cert-manager controller. Enables us to use letsencrypt to encrypt traffic with https
Manage infra and apps
- crossplane allows to manage infrastructure the kubernetes way
- kubevela allows deployment as code, cloud agnostic.
Collect metrics, observe and alert
Seeing the statistics and what is going on
- prometheus to collect metrics + grafana to observe
Collect logs
Policies
- kyverno policies can validate, mutate, generate, and cleanup Kubernetes resources plus ensure OCI image supply chain security.
- open policy gatekeeper another kubernetes policies manager
