the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work

liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a

# 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: alpha
|
||||
|
||||
## 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) 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 backwards 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).

|
||||
|
||||
## Getting started
|
||||
|
||||
### Prerequisites
|
||||
|
||||
Latest verion of `runc` is expected to be installed on the system. It is picked up as the default runtime by crio.
|
||||
|
||||
### Build Dependencies
|
||||
|
||||
**Required**
|
||||
|
||||
Fedora, CentOS, RHEL, and related distributions:
|
||||
|
||||
```bash
|
||||
yum install -y \
|
||||
btrfs-progs-devel \
|
||||
device-mapper-devel \
|
||||
glib2-devel \
|
||||
glibc-devel \
|
||||
glibc-static \
|
||||
gpgme-devel \
|
||||
libassuan-devel \
|
||||
libgpg-error-devel \
|
||||
libseccomp-devel \
|
||||
libselinux-devel \
|
||||
ostree-devel \
|
||||
pkgconfig \
|
||||
runc
|
||||
```
|
||||
|
||||
Debian, Ubuntu, and related distributions:
|
||||
|
||||
```bash
|
||||
apt install -y \
|
||||
btrfs-tools \
|
||||
libassuan-dev \
|
||||
libdevmapper-dev \
|
||||
libglib2.0-dev \
|
||||
libc6-dev \
|
||||
libgpgme11-dev \
|
||||
libgpg-error-dev \
|
||||
libseccomp-dev \
|
||||
libselinux1-dev \
|
||||
pkg-config \
|
||||
runc
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
**Optional**
|
||||
|
||||
Fedora, CentOS, RHEL, and related distributions:
|
||||
|
||||
(no optional packages)
|
||||
|
||||
Debian, Ubuntu, and related distributions:
|
||||
|
||||
```bash
|
||||
apt 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: `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)
