Simple Keystore API

Exposes following APIs:

1. getall
2. set
3. get/<key>
4. search?prefix=<pattern> and search?suffix=<pattern>
5. del/<key>

Examples:

1. get all

→ curl -s --location --request GET 'http://simple-keystore.info/getall'|jq 
    {
    "abc-2": "abc-2",
    "key1": "value1",
    "key2": "value2",
    "key3": "value3",
    "xyz-1": "xyz-1",
    "xyz-2": "xyz-2"
    } 

2. get/<key>

→ curl -s --location --request GET 'http://simple-keystore.info/get/abc-1'|jq
"abc-1"

3. set key (sample payload)

→ curl -s --location --request POST 'http://simple-keystore.info/set' \
--header 'Content-Type: application/json' \
--data-raw '{
    "xyz-3": "xyz-3"
}' |jq
{
  "abc-1": "abc-1",
  "abc-2": "abc-2",
  "key1": "value1",
  "key2": "value2",
  "key3": "value3",
  "xyz-1": "xyz-1",
  "xyz-2": "xyz-2",
  "xyz-3": "xyz-3"
}

4. search prefix

→ curl -s --location --request GET 'http://simple-keystore.info/search?prefix=abc'|jq
[
  "abc-1",
  "abc-2"
]

5. search suffix

→ curl -s --location --request GET 'http://simple-keystore.info/search?suffix=-1'|jq
[
  "abc-1",
  "xyz-1"
]

Includes a Dockerfile and k8s yaml plus steps to deploy the same in a local minikube kubernetes setup

1. clone this repository into your local
2. enable the ingress addon for minikue(it will deoloy the nginx-ingress controller)

minikube addons enable ingress

minikube ip will act as the entry point for external traffic here(in case of cloud we will deploy a loadbalancer) 3. create the keystore deployment

kubectl create -f k8s/deployment.yaml

4. expose the service

kubectl expose deployment keystore  --port=5000

5. create the ingress rule

kubectl create -f k8s/ingress.yaml

6. check if the keystore app pods are running

→ kubectl get pods
NAME                        READY   STATUS    RESTARTS   AGE
keystore-56ccbb9fb6-7f2gq   1/1     Running   0          32m
keystore-56ccbb9fb6-h7n4b   1/1     Running   0          32m
keystore-56ccbb9fb6-q29lw   1/1     Running   0          32m

7. create a local dns entry in the hosts file for the minikube ip.

echo "$(minikube ip) simple-keystore.info" | sudo tee -a /etc/hosts

Test Coverage:

Validates 200 status code and respose body get/set/search api calls
