Migrate microservice architecture to serverless architecture based on Fission.

Environment: OS X
Fission: 0.7.1
Kubernete: Minikube v0.26.0

Start service

Check front-end/helper/index.js and replace fission port number with your native configuration.

$ fission function create --name serverless-catalogue --code /serverless-catalogue/native/serverless-catalogue.js
$ fission route create --url /serverless-catalogue --function serverless-catalogue
$ cd front-end
$ npm install && npm start
$ cd ../microservice-catalogue
$ docker-compose up

Demo test

$ fission env create --name nodejs --image fission/node-env
$ curl https://raw.githubusercontent.com/fission/fission/master/examples/nodejs/hello.js > hello.js
$ fission function create --name hello --env nodejs --code hello.js
$ fission route create --method GET --url /hello --function hello
$ fission function test --name hello

Scripts

Some workflow to improve efficiency.

Useful fission command line:

list all fission function and route deployment

$ fission function list
$ fission route list

Test fission function

$ fission function test --name <function-name>

Check function logs

$ fission function logs --name <function-name>

Useful kubenetes command line:

Check namesapces

$ kubectl get namespaces

Chcek kubernete system management

$ kubectl get pods -n kube-system

Check helm deploy

$ helm list

Check fission function deploy

$ kubectl get pods -n fission-function

Check fission deployment

$ kubectl get svc -n fission

Useful docker command line:

Stop all docker container

$ docker stop (docker ps -aq)

Remove all docker container

$ docker rmi (docker images -aq)

Other useful command line:

Check port usage

$ sudo lsof -i:80

Check cpu usage

$ top
