This is a Terraform tutorial for beginners.<\/p>\n
Terraform was created on May 21st, 2014 by Mitchell Hashimoto. Hashimoto was Hashicorp’s founder. Terraform is used for building code and handling infrastructure security. Terraform is a popular DevOps tool in the software world.<\/p>\n
Terraform is necessary on the operating system in which you want to execute the code.<\/p>\n
You can download Terraform from this website<\/a>. <\/p>\n You can set up the Terraform by using the command below on macOS:<\/p>\n Terraform Setup<\/em><\/span><\/p>\n You can run this command to check if it is working:<\/p>\n Terraform Execution<\/em><\/span><\/p>\n The output of the above command executed is shown below:<\/p>\n Terraform Execution Output<\/em><\/span><\/p>\n The terraform execution command has other options which are shown below:<\/p>\n Terraform Execution Options<\/em><\/span><\/p>\n You can create a Terraform Project using resource definitions. Resource definitions are the files with the suffix .tf. You can use Terraform’s language for configuring the resources like EC2 instance, an Azure MariaDB, or a DNS entry. You can create a sample Terraform project with the commands shown below:<\/p>\n Terraform Project Creation Commands<\/em><\/span><\/p>\n The above main.tf file has resource and provider definitions. Local provider version 1.4 or other compatible version is used. sample of type local_file has the resource definition. You can run the terraform project by using the command below:<\/p>\n Terraform Project Execution<\/em><\/span><\/p>\n The output of the above command when executed is shown below:<\/p>\n<\/p>\n Terraform Project Execution Output<\/em><\/span><\/p>\n<\/a>2.3 Setup<\/h3>\n
2.3.1 Terraform Setup<\/h4>\n
brew tap hashicorp\/tap\nbrew install hashicorp\/tap\/terraform\n<\/pre>\n
terraform -v\n<\/pre>\n
apples-MacBook-Air:~ bhagvan.kommadi$ terraform -v\nTerraform v1.1.5\non darwin_amd64\napples-MacBook-Air:~ bhagvan.kommadi$\n<\/pre>\n
$ terraform Usage: terraform [-version] [-help] [args] ... help content omitted\n<\/pre>\n
2.4 Start a New Terraform Project<\/h3>\n
$ cd $HOME\n$ mkdir sample-terraform\n$ cd sample-terraform\n$ cat > main.tf <<EOF\nprovider \"local\" {\n version = \"~> 1.4\"\n }\nresource \"local_file\" \"sample\" {\ncontent = \"sample, Terraform\"\nfilename = \"sample.txt\"\n}\nEOF\n<\/pre>\nterraform init\n<\/pre>\n
apples-MacBook-Air:sample-terraform bhagvan.kommadi$ terraform init\n\nInitializing the backend...\n\nInitializing provider plugins...\n- Finding hashicorp\/local versions matching \"~> 1.4\"...\n- Installing hashicorp\/local v1.4.0...\n- Installed hashicorp\/local v1.4.0 (signed by HashiCorp)\n\nTerraform has created a lock file .terraform.lock.hcl to record the provider\nselections it made above. Include this file in your version control repository\nso that Terraform can guarantee to make the same selections by default when\nyou run \"terraform init\" in the future.\n\n\u2577\n\u2502 Warning: Version constraints inside provider configuration blocks are deprecated\n\u2502 \n\u2502 on main.tf line 2, in provider \"local\":\n\u2502 2: version = \"~> 1.4\"\n\u2502 \n\u2502 Terraform 0.13 and earlier allowed provider version constraints inside the\n\u2502 provider configuration block, but that is now deprecated and will be removed\n\u2502 in a future version of Terraform. To silence this warning, move the provider\n\u2502 version constraint into the required_providers block.\n\u2575\n\nTerraform has been successfully initialized!\n\nYou may now begin working with Terraform. Try running \"terraform plan\" to see\nany changes that are required for your infrastructure. All Terraform commands\nshould now work.\n\nIf you ever set or change modules or backend configuration for Terraform,\nrerun this command to reinitialize your working directory. If you forget, other\ncommands will detect it and remind you to do so if necessary.\n<\/pre>\n
