Docker Desktop

To run Istio with Docker Desktop, install a version which contains a supported Kubernetes version (1.17, 1.18, 1.19).
If you want to run Istio under Docker Desktop’s built-in Kubernetes, you need to increase Docker’s memory limit under the Advanced pane of Docker Desktop’s preferences. Set the resources to 8.0 GB of memory and 4 CPUs.
Docker Preferences
Minimum memory requirements vary. 8 GB is sufficent to run Istio and Bookinfo. If you don’t have enough memory allocated in Docker Desktop, the following errors could occur:
- image pull failures
- healthcheck timeout failures
- kubectl failures on the host
- general network instability of the hypervisor
Additional Docker Desktop resources may be freed up using:
```
$ docker system prune
```
