terraform

# Terraform Manage infrastructure as code using Terraform CLI. ## Initialize ```bash cd /workspace/infra && terraform init ``` ## Plan (preview changes) ```bash cd /workspace/infra && terraform plan -no-color ``` ## Plan with specific target ```bash cd /workspace/infra && terraform plan -target=aws_instance.web -no-color ``` ## Apply changes ```bash cd /workspace/infra && terraform apply -auto-approve -no-color ``` ## Destroy ```bash cd /workspace/infra && terraform destroy -auto-approve -no-color ``` ## Show state ```bash cd /workspace/infra && terraform state list ``` ```bash cd /workspace/infra && terraform state show aws_instance.web ``` ## Output values ```bash cd /workspace/infra && terraform output -json | jq . ``` ## Validate configuration ```bash cd /workspace/infra && terraform validate -no-color ``` ## Format check ```bash cd /workspace/infra && terraform fmt -check -recursive -no-color ``` ## Show providers ```bash cd /workspace/infra && terraform providers ``` ## Workspace management ```bash terraform workspace list ``` ```bash terraform workspace select staging ``` ## Import existing resource ```bash cd /workspace/infra && terraform import aws_instance.web i-1234567890abcdef0 ``` ## Notes - Always run `terraform plan` before `apply` to review changes. - Use `-no-color` flag for clean output in non-terminal environments. - Never run `terraform destroy` without explicit user confirmation. - Use workspaces or separate state files for environment isolation. - Backend configuration (S3, Azure Blob, GCS) should be set in terraform config, not CLI.
