[Stephen Grider] Microservices with Node JS and React [ENG, 2021]

Previous Version (close to original)

Here we will develop only project 2 from course.

Preparation

I am working in ubuntu linux 20.04.

Minikube, Kubectl, Docker, Skaffold should be installed.

$ sudo apt install -y jq

Minikube setup

$ curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

Kubectl setup

$ curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl && sudo mv kubectl /usr/local/bin/

Skaffold setup

$ curl -Lo skaffold https://storage.googleapis.com/skaffold/releases/latest/skaffold-linux-amd64 && chmod +x ./skaffold && sudo mv ./skaffold /usr/local/bin

Run minikube

$ export \
    PROFILE=microservices-with-nodejs-and-react \
    MEMORY=8192 \
    CPUS=4 \
    DRIVER=docker \
    KUBERNETES_VERSION=v1.22.4

$ {
    minikube --profile ${PROFILE} config set memory ${MEMORY}
    minikube --profile ${PROFILE} config set cpus ${CPUS}
    minikube --profile ${PROFILE} config set disk-size 20g

    minikube --profile ${PROFILE} config set vm-driver ${DRIVER}

    minikube --profile ${PROFILE} config set kubernetes-version ${KUBERNETES_VERSION}
    minikube start --profile ${PROFILE} --embed-certs

    // Enable ingress
    minikube addons --profile ${PROFILE} enable ingress

    // Enable registry
    // minikube addons --profile ${PROFILE} enable registry
}

$ minikube --profile ${PROFILE} ip
192.168.49.2

$ sudo vi /etc/hosts

How to run project in development mode (current version)

$ kubectl create secret generic jwt-secret --from-literal=JWT_KEY=MY_JWT_SECRET

stripe.com

Developers --> API keys

// <STRIPE_SECRET_KEY> from stripe.com
$ kubectl create secret generic stripe-secret --from-literal=STRIPE_KEY=<STRIPE_SECRET_KEY>

app/client/src/pages/orders/[orderId].js

Set your stripeKey (stripe public key) instead mine.

Need to update baseURL (Ingress HostName).

/app/client/src/api

// It will show after skaffold starts
$ kubectl get ingress
NAME          CLASS    HOSTS           ADDRESS        PORTS   AGE
ingress-svc   <none>   ticketing.dev   192.168.49.2   80      8m41s

Take ADDRESS and modify baseURL.

baseURL should looks like:

192-168-49-2.kubernetes.default.svc.cluster.local

more details

$ cd skaffold

Need to update my docker image name webmakaka/microservices*** to your in scripts from skaffold and k8s folders.

$ skaffold dev

$ kubectl get pods
