#WHAT IS KUBERNETES MANIFEST CODE#

With CloudTruth Kubernetes integration, you can create a new parameter via a project that you dedicate to your Kubernetes application. To do that, you need a place to store those Kubernetes Secrets. Even though that’s the case, you still need a way to store Kubernetes Secrets to pass into a Kubernetes application configuration. In the first section, ConfigMap Kubernetes, you learned that ConfigMaps typically store non-confidential information, like a street name or a storage volume name. You can’t store that file in source control and you can’t keep the file only on your localhost, so what can you do? CloudTruth Can Help Store Kubernetes ConfigMaps and Secrets

The secret data can be encrypted and not in plain text via the Kubernetes EncryptionConfiguration, but that doesn’t do much for the actual values that are stored in the Secrets Kubernetes manifest. Here’s the problem with the above example you’re still storing those secrets as plain text.

Taking the example code from one of the previous sections, Kubernetes ConfigMap Example, let’s create secrets with the same keys and values. This opens up a ton of security holes, which you’ll learn how you can fill in the upcoming section, CloudTruth Can Help Store Secrets. They’re stored in an unencrypted fashion using the API Servers etcd. Secret Encryptionīy default, secrets in Kubernetes are not encrypted. For example, let’s say you want to create a Kubernetes secret via the command-line using the following command: kubernetes create secret generic mynewsecretīy default, Kubernetes will use the Opaque secret type. The standard, out-of-the-box secret type for Kubernetes, is Opaque. When you’re figuring out which type of secret to use in Kubernetes, there are several options. When comparing secrets and ConfigMaps in Kubernetes, the key difference is the confidential data.īoth ConfigMaps and secrets store the data the same way, with key/value pairs, but ConfigMaps are meant for plain text data, and secrets are meant for data that you don’t want anything or anyone to know about except the application. A password, an API key, a connection string to a database, would all fall under what a secret is. When you’re thinking about secrets, it’ll essentially be any value that you don’t want the world to know about. Town2street: International Secrets in Kubernetes Both have values, and those values are the name of the streets. Notice how there are two, one is for the town’s first street, and the second is for the town’s second street. The data, which holds the key/value pairs.The metadata, which only holds the name of the ConfigMap.Now that you know what ConfigMaps in Kubernetes is, let’s take a look at an example and break it down.īelow you’ll see a ConfigMap which contains: Is there an expectation that these values may change, or will they always be static?.

Will there be other environments in play? Like Azure, AWS, on-prem, etc.?.

Will the data change across, dev, staging, and prod?.When you’re planning to use a ConfigMap, a few things you’ll want to ensure are: Instead, you use ConfigMaps because the values could change across environments. If they weren’t, you would simply add key/value pairs into a Kubernetes manifest. Kubernetes Dynamic ConfigMapsīy definition, Kubernetes ConfigMaps are meant to be dynamic. With ConfigMaps, you have the ability to create environment-specific configurations vs having to create a Kubernetes manifest for each environment and putting in the values statically. If you’re using a Kubernetes manifest that contains a Deployment or a Service, you may want to use the Docker image that you’re calling upon across multiple environments. The idea with a ConfigMap is you want the ability to pass in information at runtime to your application with the ability to keep an application portable. Kubernetes ConfigMap environment variables.A ConfigMap store’s non-confidential data, meaning no passwords or API keys. In Kubernetes, a ConfigMap is nothing more than a key/value pair. In this blog post, you’ll learn about what Kubernetes ConfigMaps and Secrets are, and how you can use them in CloudTruth. With that, the question becomes How do standard key/value pairs differ in Kubernetes? Street is the key and Mass Drive is the value of the key, Street Have you ever written a Dictionary in Python? Or a Hash Table in another programming language? If you have, you’ll notice a common trend in what they actually are key/value pairs.Ī key/value pair is a name and a value, for example:
