feat(server): replace current logging solution with log server

[0fatal]

1. Add logServerConf to regions.

use sys_db


db.Region.updateMany({}, {
  $set: {
    logServerConf: {
      apiUrl: "http://log-server.laf-system.svc.cluster.local:5060",
      secret: "secret-to-verify-app"
   }
}})

db.Region.find().pretty()

2. Deploy log-server to k8s.

kubectl apply -f - <<EOF
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    helm.sh/chart: laf-server-0.1.0
    app.kubernetes.io/name: log-server
    app.kubernetes.io/instance: server
    app.kubernetes.io/version: "1.16.0"
    app.kubernetes.io/managed-by: Helm
  name: log-server
  namespace: laf-system
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/name: log-server
      app.kubernetes.io/instance: server
  template:
    metadata: 
      labels:
        app.kubernetes.io/name: log-server
        app.kubernetes.io/instance: server
    spec:
      containers:
        - image: docker.io/lafyun/log-server:latest
          imagePullPolicy: Always
          name: log-server
          ports:
            - name: http
              containerPort: 5060
              protocol: TCP
          livenessProbe:
            httpGet:
              path: /healthz
              port: http
          readinessProbe:
            httpGet:
              path: /healthz
              port: http 
          env:
            - name: DB_URI
              value: ""
            - name: JWT_SECRET
              value: ""
---
apiVersion: v1
kind: Service
metadata:
  labels:
    helm.sh/chart: laf-server-0.1.0
    app.kubernetes.io/name: log-server
    app.kubernetes.io/instance: server
    app.kubernetes.io/version: "1.16.0"
    app.kubernetes.io/managed-by: Helm
  name: log-server
  namespace: laf-system

  ports:
    - name: http
      port: 5060
      protocol: TCP
      targetPort: http 
  selector:
    app.kubernetes.io/name: log-server
    app.kubernetes.io/instance: server
EOF

3. Add new environments to the log-server deployment.

kubectl edit deployment/log-server -n laf-system

env:
    - name: DB_URL
      value: mongodb://your-root-user:your-password@mongo-cluster-rs0-0.mongo-cluster-rs0.default.svc.cluster.local:27017/function-logs?authSource=admin&replicaSet=rs0&w=majority
    - name: JWT_SECRET
      value: "secret-to-verify-app"

4. Upgrade image version for laf-server&laf-web deployments.

kubectl set image deployments/laf-server -n laf-system \
	laf-server=docker.io/lafyun/laf-server:sha-c559cbd

kubectl set image deployments/laf-web -n laf-system \
	laf-web=docker.io/lafyun/laf-web:sha-1d22b6e

5. Upgrade image version for runtime.

 use sys_db

// runtime version
const version = "sha-83a9960"
const main_image = `docker.io/lafyun/runtime-node:${version}`
const init_image = `docker.io/lafyun/runtime-node-init:${version}`

db.Runtime.updateOne({ latest: true }, {
  $set: {
    version: version,
    image: {
      main: main_image,
      init: init_image
    }
  }
})

db.Runtime.find().pretty()

6. Restart all applications.

db.Application.updateMany({
	state: {
	  $in: ["Running"]
	}
}, {
	$set: {
		state: "Restarting"
	}
})
