Monitor Twistlock with Datadog

Twistlock is a platform for managing security and compliance within various environments, including virtual machines, containers, and serverless functions. Ensuring legal and technical security is just as valuable as preventing outages and errors, which is why Datadog is delighted to announce a new integration with Twistlock. With this integration, you can track security and compliance risks within the same platform as the metrics, traces, and logs you already collect with Datadog.

7 Key Considerations for Kubernetes in Production

Today Enterprise IT does not question the value of containerized applications anymore. Given the move to adopting DevOps and cloud native architectures, it is critical to leverage container capabilities in order to enable digital transformation. Google’s Kubernetes (K8s), an open source container orchestration system, has become the de facto standard — and the key enabler — for cloud native applications, and the way they are architected, composed, deployed, and managed.

Comparing kube-proxy modes: iptables or IPVS?

kube-proxy is a key component of any Kubernetes deployment. Its role is to load-balance traffic that is destined for services (via cluster IPs and node ports) to the correct backend pods. Kube-proxy can run in one of three modes, each implemented with different data plane technologies: userspace, iptables, or IPVS. The userspace mode is very old, slow, and definitely not recommended! But how should you weigh up whether to go with iptables or IPVS mode?

Surface Kubernetes Errors with Sentry

Kubernetes, like a lot of other tools, can be noisy. Errors and warnings often go completely unnoticed in the event stream. Or sometimes they are noticed, but are hard to understand in the context of what else is happening in the cluster. Sentry, unlike a lot of other tools, works to eliminate that noise as much as possible, including Kubernetes-related noise.

Using GitLab Auto DevOps with Kubernetes Through Rancher's Authorized Cluster Endpoint

In this post, we will walk through how to connect GitLab’s Auto DevOps feature with a Rancher-managed Kubernetes cluster, making use of a feature introduced in Rancher v2.2.0 called Authorized Cluster Endpoint. Readers can expect to walk away with an understanding of how GitLab integrates with Kubernetes and how Rancher simplifies this workflow with Authorized Cluster Endpoint.
