With Charts you can set a version for the Chart, store it in a repository called Chartmuseum, and reuse Charts for deploying a component with values. Helm is a simple template tool for Kubernetes manifests which has an ability to package your configuration for specific components into artifacts, called Charts. The problem is when you want to reuse and version these resources in the manifest. To apply changes in Kubernetes you can use raw manifest files, in which you can specify all necessary properties and deploy them into the Kubernetes cluster. You can use default resources to manage containers and communication between them, or you can define your own custom resource definitions and manage them via operators and controllers. Configurations of resources are stored in etcd storage. It provides an API that allows you to create various resources that can be configured via the YAML language. Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. Sometimes errors occur when you haven’t specified explicit dependencies. Implicit dependencies don’t work well.You don’t need to run any agent or anything. At the moment of writing Terraform has 31k stars on Github. Allows you to specify which resources are dependent on each other and which are not, and thus can be executed in parallel. One module can have dependencies on another module. #Terraform kubernetes annotations codeProvides a way to publish and reuse your code via modules. Provides a way to check infrastructure changes before applying the changes. #Terraform kubernetes annotations macYou can run Terraform CLI tool in Linux, Mac OS, FreeBSD, OpenBSD and Solaris platforms. To allow Terraform to work with your custom API, you can create a custom provider and write a logic on how terraform should interact with your resources. Flexibility to choose which cloud provider to work with. With Terraform you can store your state in different formats such as local file, AWS S3, GCP Storage Bucket, Azure Blobstorage, etc. State is a JSON representation of managed resources, and information about them. To track changes of resources and discover what will be changed if you apply your code, Terraform stores information about managed resources in state. Terraform also has many cloud and API providers such as AWS, GCP, Azure, Kubernetes, Docker, etc. It provides HCL language and CLI tools to provision and manage infrastructure resources. Terraform is an open-source tool for managing infrastructure as code.
