# For the users of mips routers (kernel 2.x): You can now block sources with IPv6 with country blocklists

Technical Challenge: Webapp deployment to AWS

The application has been deployed with the provided AWS resources and is available to view at http://testweb-elb-2116775699.eu-central-1.elb.amazonaws.com

Requirements

A one line command that, when invoked, deploys a webapp.

• App must be deployed to an EC2 instance in AWS
• The default page of the webapp must be viewable by a URL provided as output to the command.
• The webapp must not be a generic nginx or apache setup
• Only spend 3 hours creating

Easier Openstack Namespaces:

1. Put all your rc files in ~/openstack
2. Add below to your .bashrc:

# openstack rc helper function
osns () {
	for i in $(env | grep OS | cut -d = -f 1) ; do unset $i ; done
	source "$(find ~/openstack/ -type f -name $@* | head -n 1)"
}

I got most of this info from Istio and there is some tertiary info here.

Use Case

This should be used to migrate towards an istio implementation. Since existing services are not using istio, some won't be able to use MTLS. This allows you to gradually migrate.

Steps
