Make sure to create a .env file containing the keys present in the .env.example file. An API token can be retrieved from Telegram itself following their steps. A chat ID can be retrieved by starting outputChatID.go in the setup folder and sending a message to your bot username:

go run setup/outputChatID.go

docker build -t update-checker .

You can run the image directly:

docker run -it --rm --name update-checker update-checker

or you can run it by using docker compose:

docker-compose up

To execute the application directly run:

go run updateChecker.go

Optionally an argument can be passed with a full path to a folder to write the hashes to:

go run updateChecker.go /var/update-checker
