# DESCRIPTION
|
|
OCI-based implementation of Kubernetes Container Runtime Interface Daemon
|
|
|
|
crio is meant to provide an integration path between OCI conformant runtimes and the kubelet. Specifically, it implements the Kubelet Container Runtime Interface (CRI) using OCI conformant runtimes. The scope of crio is tied to the scope of the CRI.
|
|
|
|
* Support multiple image formats including the existing Docker image format
|
|
* Support for multiple means to download images including trust & image verification
|
|
* Container image management (managing image layers, overlay filesystems, etc)
|
|
* Container process lifecycle management
|
|
* Monitoring and logging required to satisfy the CRI
|
|
* Resource isolation as required by the CRI

|
|
|
## config

|
|
|
Outputs a commented version of the configuration file that would've been used
|

|
|
|
**--default**
|
|
Output the default configuration (without taking into account any configuration options).
