check-christmas-lottery-numbers

CLI to check the lottery numbers with the possibility to send notifications for the winning numbers using PushOver.

This CLI has been created with the intention of providing a lottery number and through the API available to check the numbers of the draw to know if any of the numbers provided have been awarded.

It must be taken into account that the CLI will check the status of the draw and in case it has not started yet it will not carry out the check of the numbers, showing a message like the following one:

2020/12/21 18:21:25 Checking the status of the Christmas lottery draw
2020/12/21 18:21:26 the draw has not started yet, it is not possible to get the results for the numbers

Installation

Go to release page and download the binary you need.

Requirements

If the user wants to send notifications, the following variables must be exported:

PUSH_OVER_NOTIFICATION_TOKEN: PushOver account token for sending notifications
PUSH_OVER_NOFITICATION_USER: PushOver Application/API token registered in account for receive notifications
MONGO_INITDB_ROOT_USERNAME: MongoDB Root Username of MongoDB host where the notifications results are going to be saved.
MONGO_INITDB_ROOT_PASSWORD: MongoDB Root Password of MongoDB host where the notifications results are going to be saved.

Example of usage

A JSON file must be provided with the people whose numbers we want to check, following the format shown below:

{
    "numbers_to_check":  [
        {
            "owner": "<owner_name_1>",
            "numbers": [
                {
                    "number": "<number_to_check>",
                    "bet_amount": <bet_amount>,
                    "origin": "<number_origin>"
                },
                . . .
                {
                    "number": "<number_to_check>",
                    "bet_amount": <bet_amount>,
                    "origin": "<number_origin>"
                }
            ]
        },
        . . .
        {
            "owner": "<owner_name_N>",
            "numbers": [
                {
                    "number": "<number_to_check>",
                    "bet_amount": <bet_amount>,
                    "origin": "<number_origin>"
                },
                . . .
                {
                    "number": "<number_to_check>",
                    "bet_amount": <bet_amount>,
                    "origin": "<number_origin>"
                }
            ]
        }
    ]
}

Helm chart

A helm chart has been created in order to run the CLI as a cronJob in Kubernetes.

It is recommended to create a unique namespace to use the chart, this can be done through the following command:

kubectl create namespace <check-christmas-lottery-numbers-namespace-name> --dry-run -o yaml | kubectl apply -f -

Below are examples of how to use the chart:

Create cronJob that executes each ten minutes check-christmas-lottery-numbers and necessary resources with sending notifications disabled:

helm upgrade --install check-christmas-lottery-numbers ./helm/check-christmas-lottery-numbers \
--set-file numbers_to_check=<number_to_check_dir> \
-n <check-christmas-lottery-numbers-namespace-name>

Create cronJob that executes each <N> minutes check-christmas-lottery-numbers and necessary resources with sending notifications disabled:

helm upgrade --install check-christmas-lottery-numbers ./helm/check-christmas-lottery-numbers \
--set config.minutesSchedulePeriod=<N> \
--set-file numbers_to_check=<number_to_check_dir> \
--set-string config.notify="false" \
-n <check-christmas-lottery-numbers-namespace-name>

Create cronJob that executes each ten minutes check-christmas-lottery-numbers and necessary resources with sending notifications enabled and store notifications enabled with a statefulset with a mongo host to store notifications results:

helm upgrade --install check-christmas-lottery-numbers ./helm/check-christmas-lottery-numbers \
--set config.push_over_notification_token=$$PUSH_OVER_NOTIFICATION_TOKEN \
--set config.push_over_notification_user=$PUSH_OVER_NOTIFICATION_USER \
--set-file numbers_to_check=<number_to_check_file_dir> \
--set-string config.notify="true" \
--set-string config.storeNotifications="true" \
--set config.mongodb.rootCredentials.username="user" \
--set config.mongodb.rootCredentials.password="password" \
--set config.mongodb.storage.className="standard" \
-n <check-christmas-lottery-numbers-namespace-name>

Create cronJob that executes each ten minutes check-christmas-lottery-numbers and necessary resources with sending notifications enabled and store notifications enabled with a statefulset with a mongo host to store notifications results, also creates a Secret with dockerhub credentials to avoid problem with limit in pull requests:

helm upgrade --install check-christmas-lottery-numbers ./helm/check-christmas-lottery-numbers \
--set config.push_over_notification_token=$PUSH_OVER_NOTIFICATION_TOKEN \
--set config.push_over_notification_user=$PUSH_OVER_NOTIFICATION_USER \
--set imageCredentials.url=https://index.docker.io/v1/  \
--set imageCredentials.username=<dockerhub_username> \
--set imageCredentials.password=<dockerhub_password> \
--set imageCredentials.name=<dockhub_pull_secret_name> \
--set-file numbers_to_check=<number_to_check_file_dir> \
--set-string config.notify="true" \
--set-string config.storeNotifications="true" \
--set config.mongodb.rootCredentials.username="user" \
--set config.mongodb.rootCredentials.password="password" \
--set config.mongodb.storage.className="standard" \
-n <check-christmas-lottery-numbers-namespace-name>

Running the tests

Due to being an application with a single entry point, it does not make sense to perform unit tests, but rather integration tests that check that the expected actions are performed based on the input parameters provided.

Tests requirements

A series of variables must be provided in order to carry out the execution of the integration tests mentioned, these variables are mentioned previously in requirements section.
