Technical Task

Booking Constraints

The campsite can be reserved for a maximum of 3 days.
The campsite can be reserved a minimum of 1 day(s) ahead of arrival and up to 1 month in advance.
Reservations can be canceled anytime.
For the sake of simplicity, assume the check-in & check-out time is 12:00 AM.

System Requirements

The users will need to find out when the campsite is available. So, the system should expose an API to provide information on the availability of the campsite for a given date range, with the default being 1 month.
Provide an endpoint for reserving the campsite. The user will provide his/her email & full name at the time of reserving the campsite along with the intended arrival date and departure date. Return a unique booking identifier to the caller if the reservation succeeds.
The unique booking identifier can be used to modify or cancel the reservation later on. Provide appropriate endpoint (s) to allow modification/cancellation of an existing reservation.
Due to the popularity of the campsite, there is a high likelihood of multiple users attempting to reserve the campsite for the same/overlapping date(s). Demonstrate with appropriate test cases that the system can gracefully handle concurrent requests to reserve the campsite.
Provide appropriate error messages to the caller to indicate the error cases.
The system should be able to handle a large volume of requests to determine campsite availability.
There are no restrictions on how reservations are stored as long as system constraints are not violated.

Implementation Details

Technologies used:

Go, gRPC
protovalidate-go (requests validation)
goimports, golines, gofumpt (code style & formatting)
PostgreSQL
Goose (DB migrations)
Docker, Docker Compose
Kubernetes

The implementation of the Campsite Bookings API(or Campgrounds API) in Go is based on a domain-centric architecture using the command and query responsibility segregation(CQRS) pattern. It's greatly inspired by the Mallbots example application in Michael Stack's book "Event-Driven Architecture in Golang"(GitHub).

These resources were also used during the work on this project:

"Distributed Services with Go" by Jeffrey Travis, GitHub
"gRPC Go for Professionals" by Clément Jean, GitHub
"Test-Driven Development in Go" by Adelina Simion, GitHub

Project Setup

Prerequisites:

Git, see this guide on how to install Git.
Make
Go (version >= 1.22), see this guide on how to install Go.

Clone the project and install the necessary tools(protoc, mockery, golines, goimports, gofumpt, golangci-lint):

$ git clone https://github.com/igor-baiborodine/campsite-booking-go.git
$ cd campsite-booking-go
$ make install-tools

If you use either IntelliJ IDEA or GoLand IDEs, follow this guide to configure it.

⚠️ Please note that all commands listed below should be executed from the project's root.

Up and Running Locally

Run with IntelliJ/GoLand IDE

Go to Run | Edit Configurations... and create a new Run/Debug configuration for the Campgrounds API as follows:

Start a PostgreSQL DB instance using Docker Compose:

$ make compose-up-postgres
# which is equivalent of
$ docker compose -f docker/docker-compose.yml -p campsite-booking-go up -d postgres

Verify the health status of the running postgres container:

$ docker inspect --format="{{.State.Health.Status}}" postgres

If the output is healthy, launch the Run/Debug configuration created in the previous step.

Run with Docker Compose

Docker images for Campgrounds API are available on Docker Hub.

Start PostgreSQL DB and Campgrounds API instances using Docker Compose:

$ make compose-up-all
# which is equivalent of
$ docker compose -f docker/docker-compose.yml -p campsite-booking-go up -d --build

Run with Kubernetes

Prerequisites:

Install kind:

$ go install sigs.k8s.io/kind@$latest
$ kind version

Install kubectl:

$ curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
$ curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256"
$ echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check
$ sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
$ kubectl version --client

Spin up a 3-node cluster:

$ make cluster-deploy
# which is equivalent of
$ kind create cluster --name local-k8s --config ./k8s/kind-config.yaml
$ kubectl cluster-info --context kind-local-k8s

Deploy PostgreSQL DB, Campgrounds API, and Envoy proxy:

$ make all-deploy
# which is equivalent of
# db-deploy
$ kubectl create secret generic postgres-secret --from-literal=POSTGRES_PASSWORD=postgres
$ kubectl create secret generic campgrounds-secret --from-literal=CAMPGROUNDS_PASSWORD=campgrounds_pass
$ kubectl create configmap initdb-config --from-file=./db/init/
$ kubectl apply -f ./k8s/postgres.yaml
# api-deploy
$ kubectl apply -f ./k8s/campgrounds.yaml
# proxy-deploy:
$ kubectl create configmap envoy-config --from-file=./k8s/envoy-config.yaml
$ kubectl apply -f ./k8s/envoy.yaml

Verify the status of created pods:

$ kubectl get pods 
# which may look like this
NAME                           READY   STATUS    RESTARTS      AGE
campgrounds-796fff564f-dgfsm   1/1     Running   2 (81s ago)   89s
campgrounds-796fff564f-qj44x   1/1     Running   2 (81s ago)   89s
campgrounds-796fff564f-vqfjz   1/1     Running   3 (61s ago)   89s
envoy-9dbcd5c66-h4p9v          1/1     Running   0             89s
postgres-0                     1/1     Running   0             2m13s

Use the port-forward command to forward Envoy’s port 8080 to localhost:8080 to test the Campgrounds services using a gRPC client:

$ PROXY_POD_NAME=$(kubectl get pods --selector=app=envoy -o jsonpath='{.items[0].metadata.name}')
$ kubectl port-forward "$PROXY_POD_NAME" 8080:8080

Tests

Unit and Integration

Execute only unit tests:

$ make test
# which is equivalent of
$ go test -race ./internal/...

Execute only integration tests:

$ make test-integration
# which is equivalent of
$ go test -tags=integration ./internal/...

Install gRPCurl:

$ go install github.com/fullstorydev/grpcurl/cmd/grpcurl@latest
$ grpcurl -version

The Campgrounds API should be up & running using either the Run with IntelliJ/GoLand IDE or Run with Docker Compose.

List the services present on the gRPC server:

$ grpcurl -plaintext localhost:8085 list
# output
campgroundspb.v1.CampgroundsService
grpc.reflection.v1.ServerReflection
grpc.reflection.v1alpha.ServerReflection

List all the RPC endpoints the campgroundspb.v1.CampgroundsService contains:

$ grpcurl -plaintext localhost:8085 describe campgroundspb.v1.CampgroundsService
# output
campgroundspb.v1.CampgroundsService is a service:
service CampgroundsService {
  rpc CancelBooking ( .campgroundspb.v1.CancelBookingRequest ) returns ( .campgroundspb.v1.CancelBookingResponse );
  rpc CreateBooking ( .campgroundspb.v1.CreateBookingRequest ) returns ( .campgroundspb.v1.CreateBookingResponse );
  rpc CreateCampsite ( .campgroundspb.v1.CreateCampsiteRequest ) returns ( .campgroundspb.v1.CreateCampsiteResponse );

GetCampsites

Start downloading the profiling data for the GetCampsites endpoint from the past 10 seconds and save it to a local file named get-campsites-profile.pprof. Then immediately execute the corresponding benchmark test:

$ make pprof-get-campsites
# which is equivalent of
$ curl --output ./tests/perf/get-campsites-profile.pprof "http://localhost:6060/debug/pprof/profile?seconds=10"
$ SERVER_ADDR=localhost:8085 go test -bench BenchmarkGetCampsites ./tests/perf

Validate the profiling data for the GetCampsites endpoint by launching the pprof tool. When prompted, enter the web option to generate a report in SVG format on a temp file, and start a web browser to view it. Alternatively, you can use the png option, to generate a report in PNG format:

$ make pprof-get-campsites-data
# which is equivalent of

Load

Prerequisites:

Install ghz:

$ go install github.com/bojand/ghz/cmd/ghz@latest

The Campgrounds API should be up & running using the Run with Docker Compose.
Run the data generator to create, for example, 100 campsites and non-consecutive bookings for each campsite:

$ go run ./datagenerator/main.go localhost:8085 100

When using the buf generate command, buf fetches the dependencies and uses them to generate the necessary files. These dependencies are not stored on your local file system in a directly accessible way. Instead, buf manages these dependencies in a non-visible, internal cache. Therefore, execute the following command to load and save the protovalidate dependency:

$ buf export buf.build/bufbuild/protovalidate --output ./campgroundspb/v1/

GetCampsites

Execute the following command to perform a basic load testing of the GetCampsites endpoint:

$ ghz --insecure --proto ./campgroundspb/v1/api.proto \
  --import-paths ./campgroundspb/buf/validate/validate.proto \
  --call campgroundspb.v1.CampgroundsService/GetCampsites \
  -n 10000 -c 10 -d '{}' localhost:8085

Where:

-n 10000 - number of requests to run
-c 10 - number of request workers to run concurrently
