Kustomize Support

Prepare Kubernetes Cluster

If there is no available Kubernetes cluster for testing, minikube is recommended. Just run minikube start.

Build and Apply Kustomize Configuration

git clone https://github.com/dragonflyoss/Dragonfly2.git
kustomize build Dragonfly2/deploy/kustomize/single-cluster-native/overlays/sample | kubectl apply -f -

Wait Dragonfly Ready

Wait all pods running

kubectl -n dragonfly-system wait --for=condition=ready --all --timeout=10m pod

Manager Console

The console page will be displayed on dragonfly-manager.dragonfly-system.svc.cluster.local:8080.

If you need to bind Ingress, you can refer to configuration options of Helm Charts, or create it manually.

Console features preview reference document console preview.

Configure Runtime Manually

Use Containerd with CRI as example, more runtimes can be found here

This example is for single registry, multiple registries configuration is here

For private registry:

# explicitly use v2 config format, if already v2, skip the "version = 2"
version = 2
[plugins."io.containerd.grpc.v1.cri".registry.mirrors."harbor.example.com"]
endpoint = ["http://127.0.0.1:65001", "https://harbor.example.com"]

For docker public registry:

# explicitly use v2 config format, if already v2, skip the "version = 2"
version = 2
[plugins."io.containerd.grpc.v1.cri".registry.mirrors."docker.io"]
endpoint = ["http://127.0.0.1:65001", "https://registry-1.docker.io"]

Add above config to /etc/containerd/config.toml and restart Containerd

systemctl restart containerd

Using Dragonfly

After all above steps, create a new pod with target registry. Or just pull an image with crictl:

crictl harbor.example.com/library/alpine:latest

crictl pull docker.io/library/alpine:latest

After pulled images, find logs in dfdaemon pod:

# find pods
kubectl -n dragonfly-system get pod -l component=dfdaemon
# find logs
pod_name=dfdaemon-xxxxx
kubectl -n dragonfly-system exec -it ${pod_name} -- grep "peer task done" /var/log/dragonfly/daemon/core.log

Example output:

{
    "level": "info",
    "ts": "2021-06-28 06:02:30.924",
    "caller": "peer/peertask_stream_callback.go:77",
    "msg": "stream peer task done, cost: 2838ms",
    "peer": "172.17.0.9-1-ed7a32ae-3f18-4095-9f54-6ccfc248b16e",
    "task": "3c658c488fd0868847fab30976c2a079d8fd63df148fb3b53fd1a418015723d7",
    "component": "streamPeerTask"
}
