### Install docker, kubectl, etc.
### Instal minikube
$ curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.14.0/kind-linux-amd64 && chmod +x ./kind && sudo mv ./kind /usr/local/bin/kind
### Create cluster (CNI=Calico, Enable ingress)
cd infra/KIND/
kind create cluster --name ticketing --config cluster-config.yaml
kind get kubeconfig --name="ticketing" > admin.conf
export KUBECONFIG=./admin.conf
kubectl apply -f https://docs.projectcalico.org/manifests/calico.yaml
kubectl -n kube-system set env daemonset/calico-node FELIX_IGNORELOOSERPF=true
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml
### Set environmental variables inside your kubernetes cluster (example)
kubectl create secret generic jwt-secret --from-literal=JWT_KEY=thisissupersecretjwtkey
kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=sk_test_51dsfHjfSGCqMWa1qdglqmD9HYWyp1cvvUC4FoYEXW0mAkV8t8P0Kx26VY4psazschjhZF8juqAvuuaU19Iwwadbx4ZKce00hcIwBHN
kubectl create secret generic stripe-pub-key --from-literal NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=sk_test_51HjfSGCqMWa1qdglqmD9HYWyp1cvvUC4FoYEXW0mAkV8t8P0Kx26VY4psazschjhZF8juqAvuuaU19Iwwbx4ZKce00hcIwBHN
### Deploy all services
kubectl apply -f infra/k8s/
kubectl apply -f infra/k8s-dev/
### Get IP address to access your application
$ kubectl get ingress
NAME CLASS HOSTS ADDRESS PORTS AGE
ingress-srv <none> ticketing.dev localhost 80 42m
### Setup /etc/hosts
$ grep ticket /etc/hosts
127.0.0.1 ticketing.dev
Open your browser and type http://ticketing.dev.
Snapshot of Application:
### Install and run minikube and docker
minikube start
sudo service docker start
### Add ingress nginx addon
minikube addons enable ingress
### Install ingress nginx using bare-metal yaml file
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.41.0/deploy/static/provider/baremetal/deploy.yaml
### Set environmental variables inside your kubernetes cluster(example)
kubectl create secret generic jwt-secret --from-literal=JWT_KEY=thisissupersecretjwtkey
kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=sk_test_51HjfSGCqMWa1qdglqmD9HYWyp1cvvUC4FoYEXW0mAkV8t8P0Kx26VY4psazschjhZF8juqAvuuaU19Iwwbx4ZKce00hcIwBHN

### Deploy all services
kubectl apply -f infra/k8s/
kubectl apply -f infra/k8s-dev/
### Get IP address to access your application
$ kubectl get ing
NAME CLASS HOSTS ADDRESS PORTS AGE
ingress-srv <none> ticketing.dev localhost 80 42m
### Setup /etc/hosts
$ sudo nano /etc/hosts
127.0.0.1 ticketing.dev
### Open your browser and type http://ticketing.dev
Snapshot of Application (see above)
- Docker Desktop
- Enable Kubernetes in the Docker Desktop
- Install Ingress Nginx
- Install Skaffold - Optional
- Create a Stripe Account - Optional
- Add ticketing.dev to your hosts file pointing to 127.0.0.1 (Mac & Linux /etc/hosts and Linux)
### Create the required secrets (example)
kubectl create secret generic jwt-secret --from-literal=JWT_KEY=thisissupersecretjwtkey
kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=sk_test_51HjfSGCqMWa1qdglqmD9HYWyp1cvvUC4FoYEXW0mAkV8t8P0Kx26VY4psazschjhZF8juqAvuuaU19Iwwbx4ZKce00hcIwBHN
kubectl create secret generic stripe-pub-key --from-literal NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=sk_test_51HjfSGCqMWa1qdglqmD9HYWyp1cvvUC4FoYEXW0mAkV8t8P0Kx26VY4psazschjhZF8juqAvuuaU19Iwwbx4ZKce00hcIwBHN
Note: If you have Stripe Account
kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=<REPLACE_HERE_YOUR_PRIVATE_STRIPE_KEY>
If you don't have a Stripe Account
kubectl create secret generic stripe-secret --from-literal STRIPE_KEY=123456
#### Skaffold (Optional)
# If Skaffold is installed
skaffold dev
If Skaffold is not installed
kubectl apply -f infra/k8s-dev
kubectl apply -f infra/k8s
### Setup /etc/hosts
$ grep ticket /etc/hosts
127.0.0.1 ticketing.dev // we can add minikube ip instead of localhost ip(127.0.0.1)
### Open your browser and type http://ticketing.dev
Snapshot of Application (see above)
Download Skafold (Refer to https://skaffold.dev/docs/install/)
Open a console for each microservice:
Run `npm install` for the dependencies
Inside each console run `docker build -t your-docker-id/microservice-name .` to create an image
Run `docker push your-docker-id/microservice-image` for each image you created to push them to Docker Hub
Go to each .yaml file inside ./infra and change all davarski references to your-docker-id
Open a console inside the root folder and run `skaffold dev`, this will run all the deployment config files
If the first time fail, shut it down a re-run it
Add 127.0.0.1 ticketing.dev on the last line of your hosts file
Open a web browser and go to ticketing.dev, the react app should be running
kubectl delete cluster --name=ticketing
