Juju - a model-driven operator lifecycle manager for K8s and machines
A model-driven universal operator lifecycle manager for multi cloud and hybrid cloud application management on K8s and machines.
What is an operator lifecycle manager?
Kubernetes operators are containers with operations code, that drive your applications on K8s. Juju is an operator lifecycle manager that manages the installation, integration and configuration of operators on the cluster. Juju also extends the idea of operators to traditional application management on Linux and Windows servers, or cloud instances.
Model-driven operations and integration
Organise your operators into models, which group together applications that can be tightly integrated on the same substrate and operated by the same team. Capture resource allocation, storage, networking and integration information in the model to simplify ongoing operations.
Better day-2 operations
Each operator code package, called a charm, declares methods for actions like back, restore, or security audit. Calling these methods provides remote administration of the application with no low-level access required.
The packages for RHEL 8 and RHEL 7 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 8 and RHEL 7, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 8 with the following command:
