Any other custom secret your application or architecture requires.įor more information about the different types of secrets and their explanations, check out the official documentation.Docker Login info (for private container registries).Secrets can be implemented in Kubernetes in a variety of ways. Think of Secrets as objects in Kubernetes that store restricted data so that it can be used without being revealed. Storing confidential information in a Secret is safer and more flexible than putting it verbatim in a Pod definition or a container image. Kubernetes Secrets let you store and manage sensitive information, such as passwords, OAuth tokens, and ssh keys. Eliminate Vendor Lock-In : With multi-cluster developments, organizations have the ability to switch between different vendors and evaluate costs, etc.For example, you can set up multi-cluster environments in multiple regions of Europe and the US to better serve your respective consumers. Geographical Concerns : Multi-cluster environments enable low-latency networks, which improve the experience as the cluster is available in two regions.Also, it's a great practice to separate development, staging, and production environments while also managing them in a unified manner. Separation of roles, teams, and environments : Certain policies, privacy laws, or security concerns might push an organization to separate tenants into their own cluster.Organizations get to limit fault domains with a multi-cluster setup. Resiliency : The ability to recover quickly from cluster outages or temporary failovers in a cluster is one advantage of multi-cluster environments.Why do organizations adopt multi-cluster architectures? Organizations’ reasons for leveraging multi-cluster architectures often come down to their particular needs and environment.
#WHAT IS KUBERNETES SECRETS HOW TO#
In this post, we will explore the common problem of handling confidential information in multi-cluster environments - and how to make that job easier on your team by using Kubernetes Secrets. We call this architectural pattern a multi-cluster environment, and while it can enable great benefits, it also comes with new challenges.
When leveraging Kubernetes in large enterprise environments, we often need to spread infrastructure out over multiple clusters.
