Step 2вЂЉ-вЂЉWeb scraper runs locally in docker.

WeвЂ™re going to tackle getting the web scraper running in 3 steps:

Part 3вЂЉ-вЂЉexception handling strategies for when something inevitably crashes.

Part 2вЂЉ-вЂЉAdding Browsermob Proxy to sniff traffic and have more confidence in whether the website youвЂ™re trying to scrape has loaded.

Part 1вЂЉ-вЂЉRun a Python Selenium web scraper on AWS Fargate (this).

Getting everything working on AWS required many hours of reading Stack Overflow and AWS docs and getting some conflicting information, so IвЂ™m summarizing what it took to get it done in three posts: Initially, I was running the scraper every few days from my computer but that clearly wasnвЂ™t viable so I decided to move it to AWS. In building Torres App the hardest part was getting data about campsite availability from the three different companies that manage the campsites.
