Cron + Haaukins client > enables to stop events automatically with periodic checks

Scheduler

This is a basic client command which will be used to automatically close all events in given time. It will run once in a day then checks events which has expired, then close those events no matter what is happening. There are some important parts to run this auto-cleaner for events:

1. Specify volume of configuration file
2. Bound certificates volume to docker image when docker run command takes place

Example Run

Building the image:

• docker build -t autokiller .

Running the image

In order to run stop command following command should be run :

• docker run -it --rm -v (path_of_conf_file):/app/conf.yml -v (path_of_certs):/certs autokiller -command stop

In order to run start command following command should be run :

• docker run -it --rm -v (path_of_conf_file):/app/conf.yml -v (path_of_certs):/certs autokiller -command start

Note: In order to test it on your local environment --network=host should be clarified when grpc_endpoint is localhost.

Cronjob configuration on host side

Will gonna run at 02:00 midnight and stop the events which are expired.

0 2 * * * docker run -it --rm -v (path_of_conf_file):/app/conf.yml -v (path_of_certs):/certs autokiller >> autokiller_logs

Docker container will gonna remove itself when it is done.

Test Functionality

• In order to test the functionality of this approach, setEnvVariables function should be set correctly
• According to environment variables which are specified in that function, it will make request to given grpc endpoint.
• For testing functionality, no need to use TLS for GRPC endpoint, however it can be used as well.

Todo

• Starting events automatically could be added (useful for booking functionality ...)
• Github actions for autodeploy and build should be integrated
• The functionality of this program should be tested on test environment properly
