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.
Necessity is the mother of invention, same happens here in case of docker. With the pressure of splitting monolithic applications for the purpose of ease, we arrived at docker and it made our life much simpler. We all access docker with docker-cli command but I wonder what it does behind the scene, to run a container. Let’s get deeper into it in this very blog.
Amrita InCTF 10th Edition, is an offline CTF(Capture the Flag) event hosted by Amrita university at their Amritapuri campus 10 KM away from Kayamkulam in Kerala, India. In this year’s edition two people from Opstree got invited to the final round after roughly two months of solving challenges online. The dates for the final rounds were 28th,29th and 30th December 2019. The first two days comprised of talks by various people from the industry and the third day was kept for the final competition. In the upcoming three blog series starting now, we’d like to share all the knowledge, experiences and learning from this three day event.

Have you ever faced issue that your Ansible code gets executed successfully but something went wrong like, service is not started, the configuration is not getting changed, etc?
Thanks for going through part-1 of this series, if not go check out that as well here EFK 7.4.0 Stack on Kubernetes. (Part-1). In this part, we will focus on solving our Log collection problem from docker containers inside the cluster. We will do so by deploying fluentd as DaemonSet inside our k8s cluster. DaemonSet ensures that all (or some) nodes run a copy of a pod in all worker nodes of K8s cluster. Continue reading “Collect Logs with Fluentd in K8s. (Part-2)”
So, what is the EFK Stack? “EFK” is the acronym for three open source projects: Elasticsearch, Fluentd, and Kibana. Elasticsearch is a search and analytics engine. Fluentd is a server‑side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then sends it to a “stash” like Elasticsearch. Kibana lets users visualize data with charts and graphs in Elasticsearch. Continue reading “EFK 7.4.0 Stack on Kubernetes. (Part-1)”
