Vista general

CRI-O and CRI-Tools are independent software packages available in Fedora repositories that are version matched to Kubernetes. If Kubernetes 1.34 is installed, then, when installed, CRI-O and CRI-Tools should also have the same minor version, i.e 1.34.

CRI-O

El Contenedor EjecutoR de Interface(CRI) es la interfaz del complemento que utiliza kubelet para comunicarse con el entorno de ejecución del contenedor en cada nodo que lanza pods y sus contenedores. Existen varias implementaciones de CRI, incluyendo CRI-O y containerd.

CRI-O is available in Fedora repositories as versioned rpms in parallel with Kubernetes. If kubernetes1.34 is installed and CRI-O is the designated CRI implementation, then cri-o1.34 needs to be installed.

Configuración

CRI-O configuration options are set in /etc/crio/crio.conf. This file is managed by rpm and therefore replaced when a versioned CRI-O package is replaced by another package (not counting patch level updates) such as when the cri-o1.34 rpm is replaced by the cri-o1.31 rpm. One method to create and manage custom CRI-O conifiguration settings that persist across updates is to take advantage of CRI-O support for a drop-in configuration. The default drop-in subdirectory is /etc/crio/crio.conf.d/. Settings in configuration files placed in the drop-in directory take precedence over the same setting in the default configuration file /etc/crio/crio.conf. If multiple drop-in configuration files have the same setting, the file that is sorted last in lexical order will have precedence. See crio.conf.d man file for additional information.

Herramientas CRI

CRI-Tools es un interfaz de línea de comando para cualquier implementación del CLI. CRI-Tools está disponible desde el equipo Kubernetes. Se requiere cunado utilice kubeadm para inicializar un cluster.

CRI-Tools is available in Fedora repositories as versioned rpms in parallel with Kubernetes. If kubernetes1.34 and kubernetes1.34-kubeadm are installed then cri-tools1.34 needs to be installed.

Retirement

Versioned packages for CRI-O and CRI-Tools are retired from Fedora repositories when the corresponding Kubernetes version is retired. See Versioned rpm retirement policy for additional information.
