Horacio González - Let's dive into Kubernetes operator creation
Learn how to create Kubernetes operators, a powerful way to automate tasks and manage complex software, with practical examples and insights.
- Kubernetes operators are a way to automate day-to-day tasks, just like a human operator would.
- They can be used to operate any software, but are tailored to a specific software.
- Operators are useful for complex software with many moving parts.
- They can be written in any language, but the operator framework provides SDKs for JavaScript, Go, and Java.
- To build an operator, you need to define a custom resource definition (CRD) and a controller.
- The controller watches for changes in the cluster and makes sure the desired state is achieved.
- Operators can be used to manage external resources, such as databases.
- They can also be used to manage resources that are outside of the cluster, such as monitors.
- Kubernetes operators are becoming more popular, with many large companies using them.
- You can use operators to manage your Kubernetes clusters resources that are outside of the cluster.
- Operators can be used to manage complex infrastructure, such as Kafka clusters.
- They can also be used to manage simpler infrastructure, such as PostgreSQL databases.
- Operators are useful for automating backups and other mundane tasks.
- They can also be used to automate more complex tasks, such as sharding and scaling.
- Operators can be extended to add new functionality.
- They are a way to extend the Kubernetes API.
- Operators can be used to create new resources and controllers.
- They can also be used to manage existing resources and controllers.
- Operators are used by many companies, including OVH and Aurelie.
- They are a popular choice for managing Kubernetes clusters.
- Operators can be used to manage complex applications, such as data products.
