You can roll some of these features yourself such as doing checksum and then bouncing a Pod or deleting a Pod and then re-creating it. But how does my application know that that secret has changed? Kubernetes will refresh the secret for you, but there's no mechanism built in for say, signaling my application to say the secret has changed.
What is kubernetes secrets password#
These secrets do support updates so you can imagine my password changes over time. They Support Updates, but Can't Signal That a Secret Has Changed
Access to the secret is not encrypted and it could be leaked if the etcd backend was compromised. What this means is that if you're not using an encrypted etcd storage solution, these secrets are only Base64 encoded, which is not really protected. Next it's Base64 encoded like I said, and the example showed that. Or if your application has been deleted, an operator would have to clean that up.
What is kubernetes secrets update#
This means that if the password were to change, somebody would have to go in there and update it.
Some operator has set this up for you ahead of time. What are the advantages or disadvantages of using Kubernetes Secrets? They're Staticįirst, this Kubernetes secret is a static secret. Kubernetes secrets require Base64 encoding if you create it this way. It's a password and it's a Base64 encoded password. If you have any experience with Kubernetes you've seen this before, but this secret is called mysecret and it has just one secret value in it. This is an example of a Kubernetes secret. Understanding Native Kubernetes Secrets: Pros & Cons Then I'll do three demos of the Vault Agent Injector. First, I'll talk about Kubernetes secrets, what they, are and some of the advantages of using something like the Vault Agent Injector, which is a solution by HashiCorp for consuming Vault secrets within Kubernetes. Very quickly the agenda here, and this is mostly a demo driven talk, but I'll go over a few things before I start some demos. This talk is "Vault and Kubernetes: Better Together."
I work here at HashiCorp on the Vault Ecosystem team and I lead our Kubernetes and Vault integration projects. In this talk, Jason will present the newest features of vault-helm and vault-k8s to demonstrate best-in-class techniques for lifecycle management of Vault as well as dead simple integration of any application running on Kubernetes with Vault. Vault seamlessly augments native Kubernetes workflows by providing stronger baseline security and interoperability.
