Docker configuration (currently only for local development):
docker-compose.yml - contains 3 services
server - node.js app server
dybamodb - local version od dynamodb instance
dynamodb_create_table - container running aws-cli
this container installs aws-cli
and runs aws cli-against dynamodb container (to create db table)
uses create_dynamodb_local.sh to create the db table
(this container might be replaced by seeding the db on local db connect)
docker:dev:start - starts the start npm script inside docker containerdocker:dev:stop - stops dev containersthe app is exposed to http://localhsot:4000
run docker:dev:start like for development
docker-compose.yaml exposes 9229 nodemon default debug portstart npm script passes --inspect=0.0.0.0 to nodemon which allows to connect from any address
use WebStorm Attach to Node.js/Chrome config with
reconnect automatically optionport 9229 which is a default nodemon --inspect port
Running on Kubernetes locally (via Minikube):
prerequisites (for your local machine)
(install docker - for building images)
install kubectl - to interact with minikube env
install minikube - to run Kubernetes locally
install minikube tunnel - to be able to get external IP from the questo-server-service (see terraform config file )
install terraform - to deploy infrastructure to Kubernetes (minikube) cluster
switch to minikube docker env
run minikube docker-env (or eval $(minikube -p minikube docker-env))
build images (from the root dir):
for questo server:
run docker build -t questo-server-image -f docker/app/Dockerfile .
for creating dynamodb table and admin user:
run docker build -t dynamodb-create-table-image -f docker/dynamodb/Dockerfile-dynamodb-table docker/dynamodb --build-arg ADMIN_PASSWD=admin123 --build-arg DYNAMODB_URL=http://questo-dynamodb-service:8000 --build-arg AWS_REGION=local
questo-dynamodb-service is a url to the service that connects to dynamodb pod to execute aws cli commands
start minikube tunnel in a separate terminal window
run Kubernetes cluster
go to ./tf/kubernetes directory:
run terraform init - to initialise terraform
run terraform plan/apply - to deploy the infrastructure to the local Minikube cluster
the service should now be running in Minikube
validate by sending a request using questo-server-service external IP address
display all services in namespace by running kubectl get all -n minikube-local-ns
copy/paste EXTERNAL-IP of questo-server-service
use it with for example Postman to send a request to the service on port 4000
