Feature 2: CNI-Genie "Multiple IP Addresses"
- Multiple IP addresses can be injected into a single container making the container reachable across multiple networks
- User-story: In a serverless platform the “Request Dispatcher” container that receives requests from customers of all different tenants needs to be able to pass the request to the right tenant. As a result, is should be reachable on the networks of all tenants
- User-story: Many Telecom vendors are adopting container technology. For a router/firewall application to run in a container, it needs to have multiple interfaces
How it should work
Step 1: same as Step 1 in README.md
- User inputs his network(s) of choice in pod annotations. For instance, the following yaml configurations can be used to get 2 IP addresses one from Weave and one from Canal:
apiVersion: v1 kind: Pod metadata: name: nginx-multiips labels: app: web annotations: cni: "weave,canal" spec: containers: - name: key-value-store image: nginx:latest imagePullPolicy: IfNotPresent ports: - containerPort: 6379
Step 3: same as Step 3 in README.md
Step 4: same as Step 4 in README.md
Feature 2 Extension: CNI-Genie "Multiple IP Addresses PER POD"
- This Work In-Progress (WIP) is an extension of Feature 2 where IP addresses are not only assigned to the container, but are also injected to the respective Pod object annotations.
- A design document was prepared and shared with Kubernetes SIG Network community.
- Watch the PoC demo to see how it works:
