`containerd` provides a daemon for managing running containers.
|
||||
|
||||
1.1 is the second major release for `containerd` with added support for CRI, the
|
||||
Kubernetes [Container Runtime Interface](https://github.com/kubernetes/community/blob/master/contributors/devel/container-runtime-interface.md).
|
||||
CRI is a new plugin which allows connecting the containerd daemon directly to a
|
||||
Kubernetes kubelet to be used as the container runtime. The CRI GRPC interface
|
||||
listens on the same socket as the containerd GRPC interface and runs in the same
|
||||
process.
|
||||
|
||||
In addition to all of the stability and bug fixes backported to 1.0,
|
||||
1.1 includes...
|
||||
|
||||
- CRI plugin
|
||||
- ZFS, AUFS, and native snapshotter
|
||||
- Improvements to the `ctr` tool
|
||||
- Better support for multiple platforms
|
||||
- Cross namespace content sharing
|
||||
- Better mount cleanup
|
||||
- Support for disabling plugins
|
||||
- TCP debug address for remote debugging
|
||||
- Update to Go 1.10
|
||||
- Improvements to the garbage collector
|
||||
|
||||
## CRI Plugin
|
||||
|
||||
This release of `cri` is a native plugin of `containerd`. It is built into
|
||||
`containerd` v1.1 and CRI services are enabled by default.
|
||||
|
||||
You can now use Kubernetes, with `containerd` directly, without having to use
|
||||
the intermediate `cri-containerd` daemon. The `cri-containerd` daemon is
|
||||
end-of-life.
|
||||
|
||||
*Note: Please [drain your node](https://kubernetes.io/docs/tasks/administer-cluster/safely-drain-node/) before
|
||||
upgrading from older versions of `cri-containerd` to `containerd` v1.1.*
|
||||
|
||||
You can [use a containerd config file to configure the `cri` plugin](https://github.com/containerd/cri/blob/v1.0/docs/config.md).
|
||||
|
||||
### Untrusted Workload Runtime
|
||||
|
||||
To run an untrusted pod on a runtime for untrusted workload, such as
|
||||
[Kata Containers](https://katacontainers.io/) or
|
||||
[Clear Containers](https://clearlinux.org/containers), you can:
|
||||
1. Configure a runtime for untrusted workload [with the config option `plugins.cri.containerd.untrusted_workload_runtime`](https://github.com/containerd/cri/blob/v1.0.0/docs/config.md).
|
||||
2. Create an untrusted pod by setting the annotation `io.kubernetes.cri.untrusted-workload` to `"true"`, for example:
|
||||
```yaml
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: nginx
|
||||
annotations:
|
||||
io.kubernetes.cri.untrusted-workload: "true"
|
||||
spec:
|
||||
containers:
|
||||
- name: nginx
|
||||
image: nginx
|
||||
```
|
||||
|
||||
By default, `cri` will run pods with the default runtime. However, if a pod has
|
||||
the `io.kubernetes.cri.untrusted-workload` annotation, the `cri` plugin will run
|
||||
the pod with the runtime for untrusted workloads.
|
||||
|
||||
Unless configured otherwise, the default runtime is set to
|
||||
[runc](https://github.com/opencontainers/runc).
|
||||
|
||||
### Container Runtime Interface v1alpha2
|
||||
|
||||
The supported CRI (Container Runtime Interface) version for Kubernetes v1.10 is
|
||||
now `v1alpha2.` This release of `containerd/cri` has been updated to use CRI `v1alpha2`, so
|
||||
**it only works with Kubernetes v1.10+.**
|
||||
|
||||
New CRI features added in `v1alpha2` are all supported:
|
||||
* Container log rotation: Kubelet rotates container logs.
|
||||
* Shared pid namespace: Support sharing pid namespace inside a pod.
|
||||
|
||||
### Registry Mirror
|
||||
|
||||
You can now setup registry configurations with the config option
|
||||
`plugins.cri.registry`.
|
||||
|
||||
Currently only the `mirrors` option is supported. With it, you can specify
|
||||
registry mirrors and secure/insecure connections.
|
||||
([doc](https://github.com/containerd/cri/blob/v1.0.0/docs/registry.md))
|
||||
|
||||
### End-To-End Test
|
||||
|
||||
In terms of testing, we've passed:
|
||||
* ALL CRI validation tests
|
||||
* ALL node e2e tests
|
||||
* ALL e2e tests
|
||||
|
||||
The containerd test coverage on GCE is equivalent with Docker now.
|
||||
|
||||
All the test results are public: https://k8s-testgrid.appspot.com/sig-node-containerd.
|
||||
|
||||
### Performance
|
||||
|
||||
We significantly improved pod start latency and cpu/memory usage of `cri` plugin
|
||||
this release.
|
||||
|
||||
The continuous benchmark result is published on http://node-perf-dash.k8s.io/.
|
||||
Job `ci-kubernetes-node-kubelet-benchmark` is for Docker 17.03, and
|
||||
`ci-cri-containerd-node-e2e-benchmark` is for containerd with `cri` plugin.
|
||||
|
||||
All metrics of containerd are either better or comparable with Docker 17.03.
|
||||
|
||||
## Try It Out
|
||||
|
||||
If you would like to try containerd, please download the binaries included on
|
||||
this release. If you are using Docker, this version of containerd will be used
|
||||
in the next major release of Docker.
|
||||
|
||||
To set up containerd with Kubernetes...
|
||||
* For a production quality cluster on GCE brought up with `kube-up.sh`, see [here](https://github.com/containerd/cri/blob/v1.0.0/docs/kube-up.md).
|
||||
* For a multi-node cluster installer and bring up steps using ansible and kubeadm, see [here](https://github.com/containerd/cri/blob/v1.0.0/contrib/ansible/README.md).
|
||||
* For creating a cluster from scratch on Google Cloud, see [Kubernetes the Hard Way](https://github.com/kelseyhightower/kubernetes-the-hard-way).
|
||||
* For a custom installation from release tarball, see [here](https://github.com/containerd/cri/blob/v1.0.0/docs/installation.md).
|
||||
* To install using LinuxKit on a local VM, see [here](https://github.com/linuxkit/linuxkit/tree/master/projects/kubernetes).
|
||||
|
||||
## Support
|
||||
|
||||
The [_support horizon_](https://github.com/containerd/containerd/blob/master/RELEASES.md#support-horizon)
|
||||
for containerd has been updated to include the 1.1 release. With the addition of
|
||||
the CRI plugin, we are expanding the support horizon for 1.1 to include the
|
||||
entire lifespan of Kubernetes 1.10. The containerd 1.1 release train will be
|
||||
considered an active branch with new patches until April 23, 2019 at the
|
||||
earliest, when 1.2 is released, or until Kubernetes 1.10 reaches end of life.
|
||||
The 1.1 containerd API is completely compatible with 1.0, any client using 1.0
|
||||
can safely upgrade to 1.1 without any incompatibilies. The CRI interface
|
||||
included with the CRI plugin is only supported for Kubernetes 1.10. The CRI
|
||||
interface is still considered alpha and will only be supported for Kubernetes
|
||||
1.10. The CRI plugin in containerd 1.1 will also only be supported for
|
||||
Kubernetes 1.10.
