• Passwords are hashed using a Argon2id hash function using Blake2.
• Oauth2 Integration w/ Google
• Canary integrations for gradual rollouts

choco install golang
choco install nodejs
choco install python
choco install protoc

• Notice about PBs

1. PBs and .proto files are used to define messaging and the functions utilized in a GRPC service.

2. The PB file is generated by running the below command in the communicating service's language. It can then be imported, registered to a GRPC server, and then invoked from the client.

• Make sure your GoPath is set before generating these

vi ~./zshrc
    export GOPATH=$HOME/go
    export PATH=$PATH:$GOPATH/bin

brew install protobuf
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest

protoc \
--go_out=. --go_opt=paths=source_relative \
--go-grpc_out=. --go-grpc_opt=paths=source_relative \
blog.proto

protoc \
--go_out=. --go_opt=paths=source_relative \
--go-grpc_out=. --go-grpc_opt=paths=source_relative \
auth.proto

• In order to run these services you will need to create credentials

cd service-auth
mkdir keys
cd keys
openssl genrsa -out app.rsa 1024

cd service-interets
mkdir keys
cd keys
openssl rsa -in app.rsa -out app.rsa.pub -pubout -outform PEM

1. Go to Google Cloud Credentials Page
2. Click Create New Credentials and in the Drop Down Select Oauth2
3. Select Web Application as the application type
4. Entire in http://localhost:3000 as the the redirect uri
5. Save and download the credentials and place in the root of service-auth

choco install aws-cli
choco install docker
choco install terraform
choco install kubernetes-cli
choco install kubernetes-helm
choco install minikube

docker run -p 9100:9100 service-interests
docker run -p 8001:8001 service-blog
docker run -p 8002:8002 service-auth
docker run -p 3000:3000 meetmyinterests

1. Install Mongo & Metrics API CRDS

helm repo add mongodb https://mongodb.github.io/helm-charts
helm install community-operator mongodb/community-operator
kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml

2. Start the cluster and deploy configuration to it

docker login
minikube start
minikube tunnel

. deploy/deploy.sh - Start all services
. deploy/takedown.sh - Takedown all services

3. Handy Kubernetes Commands

kubectl logs -f -l  app.kubernetes.io/name=auth - View live logs for a application
kubectl top nodes - View Resources via Metrics API
kubectl logs <podname> - View Pod Logskube
kubectl get events - View Bad Events in Pods
kubectl get services - View Services & Internal/External Ips

echo "devopscube" | base64 //after encoding it, this becomes ZGV2b3BzY3ViZQo=

echo "ZGV2b3BzY3ViZQo=" | base64 --decode //after decoding it, this will give devopscube

To get Docker Private Repository Key

1. docker login
2. cat ~/.docker/config.json | base64
3. Copy above to dockerBase64Token in values.yaml

Linting is utilized to maintain a safe, readable, and consistent coding standard throughout the services.

• golangci-lint is used as the primary linter for the go services as it has many different types of linters avaiable.
• eslinter is used as the linter for the node/next.js project

make testcoverage && make lint
