SYNOPSIS

ocid [--config=[value]] [--conmon=[value]] [--containerdir=[value]] [--debug] [--help|-h] [--listen=[value]] [--log=[value]] [--log-format value] [--pause=[value]] [--root=[value]] [--runtime=[value]] [--sandboxdir=[value]] [--selinux] [--seccomp-profile=[value]] [--apparmor-profile=[value]] [---cni-config-dir=[value]] [---cni-plugin-dir=[value]] [--version|-v]

DESCRIPTION

OCI-based implementation of Kubernetes Container Runtime Interface Daemon

ocid 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 ocid 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

--root="" OCID root dir (default: "/var/lib/ocid")

--runtime="" OCI runtime path (default: "/usr/bin/runc")

--sandboxdir="" OCID pod sandbox dir (default: "/var/lib/ocid/sandboxes")

--selinux=true|false Enable selinux support (default: false)

--seccomp_profile="" Path to the seccomp json profile to be used as the runtime's default (default: "/etc/ocid/seccomp.json")

--apparmor_profile="" Name of the apparmor profile to be used as the runtime's default (default: "ocid-default")

COMMANDS

OCID's default command is to start the daemon. However, it currently offers a single additional subcommand.

config

Outputs a commented version of the configuration file that would've been used by OCID. This allows you to save you current configuration setup and then load it later with --config. Global options will modify the output.

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