Long story short: I need events in my application.<\/strong><\/p>\n

A little bit more about the project: I\u2019m building a large-scale web application with micro-service architecture. We use\u00a0Kubernetes<\/strong> to deploy our micro-services with Ambassador<\/strong>\u00a0acting as the gateway. Everything works great until I need to have a\u00a0prefix<\/strong>\u00a0for my Socket.io micro-service.<\/p>\n

As usual, I create my service yaml like this:<\/p>\n

\u2014 -\r\napiVersion: v1\r\nkind: Service\r\nmetadata:\r\n name: test-socket\r\n annotations:\r\n getambassador.io\/config: |\r\n \u2014 -\r\n apiVersion: ambassador\/v1\r\n kind: Mapping\r\n name: test_socket_mapping\r\n prefix: \/test\/\r\n service: test-socket\r\n timeout_ms: 20000\r\n use_websocket: true\r\nspec:\r\n selector:\r\n app: test-socket\r\n ports:\r\n \u2014 name: first\r\n protocol: TCP\r\n port: 443\r\n targetPort: 8000\r\n \u2014 name: second\r\n protocol: TCP\r\n port: 80\r\n targetPort: 8000<\/span><\/pre>\n
Also the deployment yaml like this:<\/p>\n
apiVersion: extensions\/v1beta1\r\nkind: Deployment\r\nmetadata:\r\n  name: test-socket\r\nspec:\r\n  replicas: 1\r\n  strategy:\r\n    type: RollingUpdate\r\n  template:\r\n    metadata:\r\n      labels:\r\n        app: test-socket\r\n    spec:\r\n      containers:\r\n      - name: spiderkube-event-container\r\n        image: sylhero\/test-socket\r\n        env:\r\n        - name: NODE_ENV\r\n          value: \"development\"\r\n        imagePullPolicy: Always\r\n        ports:\r\n        - containerPort: 8000\r\n        livenessProbe:\r\n          tcpSocket:\r\n            port: 8000\r\n          initialDelaySeconds: 30\r\n          periodSeconds: 10\r\n          successThreshold: 1<\/span><\/pre>\n
Life is good. All I need to do is connect my newly deployed test-socket micro-service with my socket client.<\/p>\n
I have a simple test client like this:<\/p>\n
const\r\n    io = require(\"socket.io-client\"),\r\n    ioClient = io.connect(\"https:\/\/dev.test.io<\/a>\/test\"); <\/span><\/pre>\n
What I expect to see on the pod log is something that says \u201cconnection success\u201d or \u201creceiving request from 1.1.1.1\u201d, etc. However, I don\u2019t see anything on the pod log. Everything works fine on my local! After I spent a whole day looking into this, I finally figured out:<\/p>\n
It\u2019s the\u00a0client path<\/strong>.<\/p>\n
I updated my test client code like this:<\/p>\n
const\r\n    io = require(\"socket.io-client\"),\r\n    ioClient = io.connect(\"https:\/\/dev.test.io<\/a>\", {\r\n     path: \"\/test\/socket.io\/\"\r\n    });<\/span><\/pre>\n
Voila! Now it works like a charm!<\/p>\n
Ambassador is a great gateway for Kubernetes but it\u2019s also very new as a result, documentation is always in need. Hopefully, my small article can contribute to it and help people who are doing the same thing with Ambassador.<\/p>\n
