This can happen, and you should be prepared for it as well. This is also the article in this series to mention. In this series of tutorials we'll show you what you need to track, why you're tracking them, and what you need to do to deal with possible root causes.
We'll show you each indicator, how to track it, and what you can do to take action. We will use different tools to collect and analyze this data.
challenges and suggestions for migrating to k8s and cloud native.The problem problemEarlier this year, we started containerized deployment of the Sematext cloud, which seems to be very simple. What the enterprise needs to do is to package all the applications, create some kubernetes configurations for their resources (such as deployments, services, etc.), and then proceed. However, it is not that easy.The main problem is that everything that is used

volume plugins.1.8, the storage interest group extends the kubernetes storage API, no longer simply provides the available volumes, but also adds volume expansion and snapshot capabilities. In addition to these alpha/prototype features, the storage interest group focuses on giving users better control over their storage, providing the ability to set temporary storage requests limits, to specify mount options, to expose more storage

The Kubernetes network model is made up of four parts from inside to outside:
The network where the pod interior container resides
The network where the pod resides
Network for communication between pod and service
Network of communication between outside and service
It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [
What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se
From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed.
Scheduling speed encountered bottlenecks, affecting the deployment of large business speed.
There is no good support for stateful services.

The beta phase, such as V2BETA3, is enabled by default. Indicates that this part of the code has been tested and the basic functionality has been validated. However, there is a possibility that incompatible changes will occur in the API object of this state in the future to over-stable the stable phase.
The stable phase, such as V1, is a stable software release phase, and API objects generally do not change much later.Next, let's introduce the main structure o
