minikube configuration reference

|
|
## Flags
|
|
|
|
Most minikube configuration is done via the flags interface. To see which flags are possible for the start command, run:
|
|
|
|
```shell
|
|
minikube start --help
|
|
```
|
|
|
|
For example:
|
|
|
|
```shell
|
|
minikube start --apiserver-port 9999
|
|
```
|
|
|
|
Many of these flags are also available to be set via persistent configuration or environment variables.
|
|
While most flags are applicable to any command, some are globally scoped:
|
|
|
|
```
|
|
Flags:
|
|
--alsologtostderr log to standard error as well as files
|
|
-b, --bootstrapper string The name of the cluster bootstrapper that will set up the kubernetes cluster. (default "kubeadm")
|
|
-h, --help help for minikube
|
|
--log_backtrace_at traceLocation when logging hits line file:N, emit a stack trace (default :0)
|
|
--log_dir string If non-empty, write log files in this directory
|
|
--logtostderr log to standard error instead of files
|
|
-p, --profile string The name of the minikube VM being used.
|
|
This can be modified to allow for multiple minikube instances to be run independently (default "minikube")
|
|
--stderrthreshold severity logs at or above this threshold go to stderr (default 2)
|
|
-v, --v Level log level for V logs
|
|
--vmodule moduleSpec comma-separated list of pattern=N settings for file-filtered logging
|
|
```
|
|
|
|
## Persistent Configuration
|
|
|
|
minikube allows users to persistently store new default values to be used across all profiles, using the `minikube config` command. This is done providing a property name, and a property value.
|
|
|
|
### Listing config properties
|
|
|
|
```shell
|
|
minikube config
|
|
```
|
|
|
|
Example:
|
|
|
|
```shell
|
|
Configurable fields:
|
|
|
|
* driver
|
|
* feature-gates
|
|
* v
|
|
* cpus
|
|
* disk-size
|
|
* host-only-cidr
|
|
* memory
|
|
* log_dir
|
|
* kubernetes-version
|
|
* iso-url
|
|
* WantUpdateNotification
|
|

|
|
* disable-driver-mounts
|
|

|
|
```
|
|
|
|
### Listing your property overrides
|
|
|
|
```shell
|
|
minikube config view
|
|
```
|
|
|
|
Example output:
|
|
|
|
```shell
|
|
- memory: 4096
|
|
- registry: true
|
|
- driver: vmware
|
|
- dashboard: true
|
|
- gvisor: true
|
|
```
|
|
|
|
### Setting a new property override
|
|
|
|
|
|
```shell
|
|
minikube config set <key> <value>
|
|
```
|
|
|
|
For example:
|
|
|
|
```shell
|
|
minikube config set driver hyperkit
|
|
```
|
|
|
|
## Environment Configuration
|
|
|
|
### Config variables
|
|
|
|
minikube supports passing environment variables instead of flags for every value listed in `minikube config`. This is done by passing an environment variable with the prefix `MINIKUBE_`.
|
|
|
|
For example the `minikube start --iso-url="$ISO_URL"` flag can also be set by setting the `MINIKUBE_ISO_URL="$ISO_URL"` environment variable.
|
|
|
|
### Other variables
|
|
|
|
Some features can only be accessed by environment variables, here is a list of these features:
|
|
|
|
* **MINIKUBE_HOME** - (string) sets the path for the .minikube directory that minikube uses for state/configuration
|
|
|
|
* **MINIKUBE_IN_STYLE** - (bool) manually sets whether or not emoji and colors should appear in minikube. Set to false or 0 to disable this feature, true or 1 to force it to be turned on.
|
|
|
|
* **MINIKUBE_WANTUPDATENOTIFICATION** - (bool) sets whether the user wants an update notification for new minikube versions
|
|
|
|
* **MINIKUBE_REMINDERWAITPERIODINHOURS** - (int) sets the number of hours to check for an update notification
|
|
|
|
* **CHANGE_MINIKUBE_NONE_USER** - (bool) automatically change ownership of ~/.minikube to the value of $SUDO_USER
|
|
|
|
* **MINIKUBE_ENABLE_PROFILING** - (int, `1` enables it) enables trace profiling to be generated for minikube
|
|
|
|
### Making environment variables persistent
|
|
|
|
To make the exported variables persistent:
|
|
|
|
* Linux and macOS: Add these declarations to `~/.bashrc` or wherever your shells environment variables are stored.
|
|
* Windows: Add these declarations via [system settings](https://support.microsoft.com/en-au/help/310519/how-to-manage-environment-variables-in-windows-xp) or using [setx](https://stackoverflow.com/questions/5898131/set-a-persistent-environment-variable-from-cmd-exe)
|
|
|
|
#### Example: Disabling emoji
|
|
|
|
```shell
|
|
export MINIKUBE_IN_STYLE=false
|
|
minikube start
|
|
```
