Minikube ISO & Image Cache Folder (~/.minikube/cache)

Bottom Line: It is 100% safe to clear the Minikube cache. Running minikube cache delete or purging ~/.minikube/cache will not delete your Kubernetes deployment manifests or YAML configurations.

What is the Minikube Cache Folder?

Located at ~/.minikube/cache (and %USERPROFILE%\.minikube\cache on Windows), this folder is created by Minikube (the local Kubernetes cluster engine for developers).

Minikube caches:

• ISO Images (cache/iso): Virtualization ISO images (Boot2Docker / Minikube ISOs) used to launch Kubernetes node VMs.
• Preloaded Images (cache/images): Cached container image tarballs (k8s.gcr.io, etcd, coredns) downloaded during cluster creation.

Over multiple Kubernetes version updates, obsolete Minikube ISO files and old cluster images hoard 5 GB to 20 GB+ of storage.

Can You Delete Minikube Cache?

✅ Yes, it is safe to delete.

• No project code lost: Your .yaml Kubernetes manifests, Helm charts, and local source code remain untouched.
• Auto-downloaded: The next time you start a cluster (minikube start), Minikube will simply re-fetch the single ISO image required for that Kubernetes version.

How to Safely Clean Up Minikube Cache

Method 1: Using the Minikube CLI (Recommended)

1. Open your terminal.
2. Delete cached container images:

   minikube cache delete

3. To delete old local Minikube cluster profiles and ISO caches completely:

   minikube delete --all --purge
