Recently, we explored Preserving the Source IP address on AWS Classic Loadbalancer and Istio’s envoy using the proxy protocol in our first Part. Continuing to the second part of this series, we will look at How can we apply IP whitelisting on the Kubernetes microservices!
There are some microservices behind an internet-facing loadbalancer that we want to have limited access to, based on source IP address. This will prevent our microservices from unauthorized access.
We often face complications after a certain point when we can not change the foundation layer of our code because we haven’t thought it through and didn’t plan or strategize the way of writing code in the beginning, there are certain points which should be taken under consideration similarly there are some common mistakes which we should avoid.
In the modern world, the container is a fascinating technology, as it has revolutionized software development and delivery. Everyone is using containers because of its dynamic, scalable, and isolated nature.
People do use some orchestration software such as Kubernetes, Openshift, Docker Swarm, and AWS ECS, etc to run their production workloads on containers.
While tools like Kubernetes is becoming an essential need for modern cloud-based infrastructure, there is a high potential for cloud-native CI/CD. To achieve that there is a philosophical approach has emerged i.e. GitOps. As we have discussed the important principles of GitOps in our previous blog, So in this blog, we will see how to implement GitOps in our current DevOps processes, and finally GitOps implementation in a light manner. If you haven’t gone through our previous blog, here you can take a look at it.
Initially, we had the DevOps framework in which Development and Operation team collaborated to create an agile development ecosystem. Then a new wave came with the name of “DevSecOps” in which we integrated the security into the existing DevOps process. But nowadays a new terminology “GitOps” is getting famous because of its “Single Source of Truth” nature. Its fame has reached to this level that it was a trending topic at KubeCon.
Amrita InCTF 10th Edition is an offline CTF(Capture the Flag) event hosted by Amrita University. In our previous blog, we discussed about talks from the first day. In this we’ll share some lights on the talks from second day.
