Add Virtual Link - Ubuntu 14.04


Here I am assuming that your Ubuntu machine is up and running and having a



physical interface eth0.







Add Virtual Link



$ ip link add name veth1 link eth0 type macvlan mode bridge



It will add the virtual interface veth1 without any Ip address.







Add the ip address



To add the ip address to newly created virtual link run below command



Note: Here I am assuming that you are having DHCP server configured,



         If not you can manually assign the static IP address to veth1.



$ dhclient -v veth1



This command will assign the random IP address to veth1

HTTPS for Local Development

  Switching between HTTP to HTTPS for Local Development There are millions of developers who write web applications every day. While writing these  applications generally they run them locally or in the test environment to test the functionally, before releasing them to production. These applications expose HTTP endpoint using which they can be accessed and tested. Some times it requires to test the same application using HTTPS. I came across with this use case while working on CloudWatch Metric Streams, where I wanted to send the CloudWatch Metric Streams data to the monitoring solution using Kinesis Data Firehose, and it only accepts HTTPS endpoint. To accomplish the task I wrote one spring boot application . I was running this locally and it was exposing the HTTP endpoint, and the same endpoint can not be used in the Kinesis Data Firehose. It should expose HTTPS Endpoint.  There are many ways to expose the HTTPS endpoint and using ngrok it can be easily done. Install n...
