-# CRI-O - OCI-based implementation of Kubernetes Container Runtime Interface
-
-[](https://travis-ci.org/kubernetes-incubator/cri-o)
-[](https://goreportcard.com/report/github.com/kubernetes-incubator/cri-o)
-
-### Status: Stable
-
-## What is the scope of this project?
-
-CRI-O is meant to provide an integration path between OCI conformant runtimes and the kubelet.
-Specifically, it implements the Kubelet [Container Runtime Interface (CRI)](https://github.com/kubernetes/community/blob/master/contributors/devel/container-runtime-interface.md) using OCI conformant runtimes.
-The scope of CRI-O is tied to the scope of the CRI.
-
-At a high level, we expect the scope of CRI-O to be restricted to the following functionalities:
-
-* 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
-
-## What is not in scope for this project?
-
-* Building, signing and pushing images to various image storages
-* A CLI utility for interacting with CRI-O. Any CLIs built as part of this project are only meant for testing this project and there will be no guarantees on the backward compatibility with it.
-
-This is an implementation of the Kubernetes Container Runtime Interface (CRI) that will allow Kubernetes to directly launch and manage Open Container Initiative (OCI) containers.
-
-The plan is to use OCI projects and best of breed libraries for different aspects:
-- Runtime: [runc](https://github.com/opencontainers/runc) (or any OCI runtime-spec implementation) and [oci runtime tools](https://github.com/opencontainers/runtime-tools)
-- Images: Image management using [containers/image](https://github.com/containers/image)
-- Storage: Storage and management of image layers using [containers/storage](https://github.com/containers/storage)
-- Networking: Networking support through use of [CNI](https://github.com/containernetworking/cni)
-
-It is currently in active development in the Kubernetes community through the [design proposal](https://github.com/kubernetes/kubernetes/pull/26788). Questions and issues should be raised in the Kubernetes [sig-node Slack channel](https://kubernetes.slack.com/archives/sig-node).

-
-## OCI Hooks Support
-
-[CRI-O configures OCI Hooks to run when launching a container](./hooks.md)
-
-## CRI-O Usage Transfer
-
-[Useful information for ops and dev transfer as it relates to infrastructure that utilizes CRI-O](/transfer.md)
-
-## Communication
-
-For async communication and long running discussions please use issues and pull requests on the github repo. This will be the best place to discuss design and implementation.
-
-For sync communication we have an IRC channel #CRI-O, on chat.freenode.net, that everyone is welcome to join and chat about development.
-
-## Getting started
-
-### Prerequisites
-
-Latest version of `runc` is expected to be installed on the system. It is picked up as the default runtime by CRI-O.
-
-### Build and Run Dependencies
-
-**Required**
-
-Fedora, CentOS, RHEL, and related distributions:
-
-```bash
-yum install -y \
- btrfs-progs-devel \
- device-mapper-devel \
- git \
- glib2-devel \
- glibc-devel \
- glibc-static \
- go \
- golang-github-cpuguy83-go-md2man \
- gpgme-devel \
- libassuan-devel \
- libgpg-error-devel \
- libseccomp-devel \
- libselinux-devel \
- ostree-devel \
- pkgconfig \
- runc \
- skopeo-containers
-```
-
-Debian, Ubuntu, and related distributions:
-
-```bash
-apt-get install -y \
- btrfs-tools \
- git \
- golang-go \
- libassuan-dev \
- libdevmapper-dev \
- libglib2.0-dev \
- libc6-dev \
- libgpgme11-dev \
- libgpg-error-dev \
- libseccomp-dev \
- libselinux1-dev \
- pkg-config \
- go-md2man \
- runc \
- skopeo-containers
-```
-
-Debian, Ubuntu, and related distributions will also need a copy of the development libraries for `ostree`, either in the form of the `libostree-dev` package from the [flatpak](https://launchpad.net/~alexlarsson/+archive/ubuntu/flatpak) PPA, or built [from source](https://github.com/ostreedev/ostree) (more on that [here](https://ostree.readthedocs.io/en/latest/#building)).
-
-If using an older release or a long-term support release, be careful to double-check that the version of `runc` is new enough (running `runc --version` should produce `spec: 1.0.0`), or else build your own.
-
-**NOTE**
-
-Be careful to double-check that the version of golang is new enough, version 1.8.x or higher is required. If needed, golang kits are avaliable at https://golang.org/dl/
-
-**Optional**
-
-Fedora, CentOS, RHEL, and related distributions:
-
-(no optional packages)
-
-Debian, Ubuntu, and related distributions:
-
-```bash
-apt-get install -y \
- libapparmor-dev
-```
-
-### Get Source Code
-
-As with other Go projects, CRI-O must be cloned into a directory structure like:
-
-```
-GOPATH
-└── src
- └── github.com
- └── kubernetes-incubator
- └── cri-o
-```
-
-First, configure a `GOPATH` (if you are using go1.8 or later, this defaults to `~/go`).
-
-```bash
-export GOPATH=~/go
-mkdir -p $GOPATH
-```
-
-Next, clone the source code using:
-
-```bash
-mkdir -p $GOPATH/src/github.com/kubernetes-incubator
-cd $_ # or cd $GOPATH/src/github.com/kubernetes-incubator
-git clone https://github.com/kubernetes-incubator/cri-o # or your fork
-cd cri-o
-```
-
-### Build
-
-```bash
-make install.tools
-make
-sudo make install
-```
-
-Otherwise, if you do not want to build `CRI-O` with seccomp support you can add `BUILDTAGS=""` when running make.
-
-```bash
-make BUILDTAGS=""
-sudo make install
-```
-
-#### Build Tags
-
-`CRI-O` supports optional build tags for compiling support of various features.
-To add build tags to the make option the `BUILDTAGS` variable must be set.
-
-```bash
-make BUILDTAGS='seccomp apparmor'
-```
-
-| Build Tag | Feature | Dependency |
-|-----------|------------------------------------|-------------|
-| seccomp | syscall filtering | libseccomp |
-| selinux | selinux process and mount labeling | libselinux |
-| apparmor | apparmor profile support | libapparmor |
-
-### Running pods and containers
-
-Follow this [tutorial](tutorial.md) to get started with CRI-O.
-
-### Setup CNI networking
-
-A proper description of setting up CNI networking is given in the
-[`contrib/cni` README](contrib/cni/README.md). But the gist is that you need to
-have some basic network configurations enabled and CNI plugins installed on
-your system.
-
-### Running with kubernetes
-
-You can run a local version of kubernetes with CRI-O using `local-up-cluster.sh`:
-
-1. Clone the [kubernetes repository](https://github.com/kubernetes/kubernetes)
-1. Start the CRI-O daemon (`crio`)
-1. From the kubernetes project directory, run:
-```shell
-CGROUP_DRIVER=systemd \
-CONTAINER_RUNTIME=remote \
-CONTAINER_RUNTIME_ENDPOINT='/var/run/crio.sock --runtime-request-timeout=15m' \
-./hack/local-up-cluster.sh
-```
-
-To run a full cluster, see [the instructions](kubernetes.md).
-
-### Current Roadmap
-
-1. Basic pod/container lifecycle, basic image pull (done)
-1. Support for tty handling and state management (done)
-1. Basic integration with kubelet once client side changes are ready (done)
-1. Support for log management, networking integration using CNI, pluggable image/storage management (done)
-1. Support for exec/attach (done)
-1. Target fully automated kubernetes testing without failures [e2e status](https://github.com/kubernetes-incubator/cri-o/issues/533)
-1. Track upstream k8s releases
