Minikube cluster lifecycle management¶

Minikube cluster lifecycle management refers to the operational procedures involved in initializing, configuring, maintaining, and terminating local Kubernetes clusters using Minikube.

Initialization¶

To begin the lifecycle, a cluster is started using the minikube start command^[400-devops-06-kubernetes-minikube.md]. By default, Minikube attempts to use the Docker driver, creating a containerized control plane node^[400-devops-06-kubernetes-minikube.md].

Administrators can override default parameters at startup to allocate specific resources, such as CPUs and memory^[400-devops-06-kubernetes-minikube.md].

Configuration Management¶

Minikube allows for persistent configuration settings that define the cluster's behavior and resource allocation.

Resource Allocation¶

To configure the amount of memory or CPUs allocated to the virtual machine or container, the config set subcommand is used^[400-devops-06-kubernetes-minikube.md].

Driver Selection¶

Specific drivers can be set as the default for future cluster creations^[400-devops-06-kubernetes-minikube.md].

Configuration Verification¶

Administrators can use minikube config view to display the current configuration values^[400-devops-06-kubernetes-minikube.md].

Maintenance and Operations¶

Once a cluster is running, various commands are available to manage its state and resources without fully terminating it.

Stopping and Pausing¶

The cluster can be halted using the stop command^[400-devops-06-kubernetes-minikube.md]. Alternatively, Kubernetes can be paused without impacting deployed applications using minikube pause^[400-devops-06-kubernetes-minikube.md].

Extensions and Addons¶

Users can browse and install additional services using the minikube addons list command^[400-devops-06-kubernetes-minikube.md].

Multi-cluster Management¶

The lifecycle management supports running multiple clusters simultaneously or with different configurations, such as specific Kubernetes versions^[400-devops-06-kubernetes-minikube.md].

Termination¶

The final stage of the lifecycle involves deleting the cluster.

To remove all traces of a specific cluster profile, the delete command is used^[400-devops-06-kubernetes-minikube.md]. If the goal is to clean up all clusters and profiles associated with Minikube, the --all flag can be applied^[400-devops-06-kubernetes-minikube.md].
