The idea is to design a load balancer using Docker Swarm that can distribute the load on different worker machines, based on the inter-arrival of requests.

docker-project-aws.zip has no END header #1

Closed alaiavee closed 2 hours ago

alaiavee commented 2 hours ago

FYI, trying to follow the great guide you wrote on your blog (https://abhinavcreed13.github.io/blog/docker-swarm-amazon-ec2-aws/); and at step 6 I'm hitting a road block with the zip not having an END header. So maybe the file is corrupt now?

unzip:  cannot find zipfile directory in one of docker-project-aws.zip or

Also tried jar:

The size obviously isn't right, maybe an issue with wget. I'll just work with the scp method...

Closing since it's obviously an issue with the download I'm getting via wget.

Yup looks like the zip file is not properly downloaded.

All good, glad you found the guide useful 🙂

I see, it's related to how Github serves files https://unix.stackexchange.com/a/387912

abhinavcreed13 commented 2 hours ago

I would say easier to just download the zip and upload to your server for unzipping.
