Go Watch That Site

Time to experiment with Golang! I'm waiting on deals to buy a new mountain bike and I want a simple program to scrape a site then compare it to the last scrape. If there's a change, I want to know about it.

By default, the Dockerfile sets GWTS_PRODUCT_FILE_PATH to /data/bikes. A user can mount /data to the host to persist the file between runs.

Flags

All flags can be set via environment variable or switch. If both are supplied, the switch will be used.

Required	Default	Environment	Switch	Purpose
x		GWTS_EMAIL_TO	emailTo	Set where the email will be sent to
x		GWTS_EMAIL_FROM	emailFrom	Set where the email will be sent from
x		GWTS_EMAIL_PASSWORD	emailPassword	GMail password for emailFrom SMTP
	bikes	GWTS_PRODUCT_FILE_PATH	productFilePath	Location to store products scraped between runs

Examples

Go

./go-watch-that-site -emailTo=to@email.test -emailFrom=from@email.test -emailPassword=superComplexPassword

Docker

docker build -t go-watch-that-site .
docker run -e "GWTS_EMAIL_TO=to@email.test" -e "GWTS_EMAIL_FROM=from@email.test" -e "GWTS_EMAIL_PASSWORD=superComplexPassword" go-watch-that-site
