terraform init: This command initializes a Terraform working directory, downloading the necessary providers and modules. It sets up the environment for your Terraform configuration.
terraform init -upgrade: It is used to upgrade the Terraform plugins (providers) to their latest versions.
terraform plan: This command generates an execution plan for your Terraform configuration. It helps you understand what changes will be made to your infrastructure without actually applying those changes.
terraform apply: Once you're satisfied with the execution plan, you can use this command to apply the changes and create/update resources as defined in your Terraform configuration.
terraform validate: This command checks the syntax and validity of your Terraform configuration files. It ensures that your configuration adheres to Terraform's rules and standards.
terraform fmt: It automatically formats your Terraform configuration files to follow Terraform's recommended coding style. This helps maintain consistent and readable code.
terraform destroy: This command is used to destroy all the resources created by your Terraform configuration. It's a way to clean up your infrastructure when it's no longer needed.
Terraform's Main Competitors:
Ansible: Ansible is an open-source automation tool that focuses on configuration management and application deployment. Unlike Terraform, which primarily manages infrastructure as code, Ansible can be used for broader automation tasks.
Packer: Packer, also by HashiCorp (the same company that develops Terraform), is a tool for creating identical machine images for multiple platforms. While Packer can be used alongside Terraform for provisioning, they serve different purposes.
Cloud Foundry: Cloud Foundry is a Platform-as-a-Service (PaaS) that automates application deployment, scaling, and management. It's more application-centric compared to Terraform's infrastructure focus.
Kubernetes: Kubernetes is a container orchestration platform. While Terraform can provision Kubernetes clusters, Kubernetes itself is focused on container management and orchestration.
