Terraform CLI Cheat Sheet
Learn the Learn how Terraform fits into the. Terraform is controlled via a very easy to use command-line interface CLI. Terraform is only a single command-line application: terraform. This application then takes a subcommand such as "apply" or "plan". The complete list of subcommands is in the navigation to the left. The terraform CLI is a well-behaved command line application. In erroneous cases, a non-zero exit status will be returned. It also responds to -h and --help as you'd most likely expect. To get help for any specific command, pass the -h flag to the relevant subcommand. For example, to see help about the graph subcommand:. If you use either bash or zsh as your command shell, Terraform can provide tab-completion support for all command names and at this time some command arguments. After installation, it is necessary to restart your shell or to re-read its profile script before completion will be activated. To uninstall the completion hook, assuming that it has not been modified manually in the shell profile, run the following command:. Currently not all of Terraform's subcommands have full tab-completion support for all arguments. We plan to improve tab-completion coverage over time. The Terraform CLI commands interact with the HashiCorp service Checkpoint to check for the availability of new versions and for critical security bulletins about the current version. One place where the effect of this can be seen is in terraform versionwhere it is used by default to indicate in the output when a newer version is available. Only anonymous information, which cannot be used to identify the user or host, is sent to Checkpoint. An anonymous ID is sent which helps de-duplicate warning messages. Both the anonymous id and the use of checkpoint itself are completely optional and can be disabled. Alternatively, settings in the CLI configuration file can be used to disable checkpoint features. The following checkpoint-related settings are supported in this file:. This allows Terraform to check for security bulletins but does not send the anonymous signature in these requests. The Checkpoint client code used by Terraform is available for review by any interested party. Seven elements of the modern Application Lifecycle. Create Account. The most common, useful commands are shown first, followed by less common or more advanced commands. If you're just getting started with Terraform, stick with the common commands. For the other commands, please read the help and docs before usage. Common commands: apply Builds or changes infrastructure console Interactive console for Terraform interpolations destroy Destroy Terraform-managed infrastructure env Workspace management fmt Rewrites config files to canonical format get Download and install modules for the configuration graph Create a visual graph of Terraform resources import Import existing infrastructure into Terraform init Initialize a Terraform working directory output Read an output from a state file plan Generate and show an execution plan providers Prints a tree of the providers used in the configuration refresh Update local state file against real resources show Inspect Terraform state or plan taint Manually mark a resource for recreation untaint Manually unmark a resource as tainted validate Validates the Terraform files version Prints the Terraform version workspace Workspace management All other commands: 0. If the path given is the path to a configuration, the dependency graph of the resources are shown. If the path is a plan file, then the dependency graph of the plan itself is shown. The graph is outputted in DOT format. The typical program that can read this format is GraphViz, but many web services are also available to read this format.

Ansible Cheat Sheet – A DevOps Quick Start Guide
On my last tutorial, I talked about complete steps of installing Arch Linux on a Bare metal system and on Virtual Machine. This tutorial can be accessed through the link below. Pacman is mainly developed by Arch Linux developers and used to manage software packages; install, upgrade, configure and remove software packages. Pacman package manager is written in the C programming language and uses the. It maintains a text-based package database hence allows you to query the package database for installed packages, files, and owners of those files. One special feature of Pacman is its reliable way of handling dependencies and conflicts automatically. Since the development of Pacman is currently hosted on git, you can easily fetch the current development tree using git command. To synchronize your local database with repositories before upgrading packages that are out of date on the local system, type below command on your terminal:. You can imultaneously synchronize with the repositories and update the system, enter below command:. The syntax of removing a software package while retaining its configuration s and required dependencies are:. Remove software package and its dependencies, provided those dependencies are not required by any other installed package:. To remove a package, its dependencies and configuration files generated by Pacman, enter the command:. The -n option prevents saving of important configuration files with passive extension. It prevents creation of backup files. To remove a package, its dependencies and all packages depending on the target package, enter the command:. To remove a package required by another package, without removing the dependent package, the command syntax is:. Arch avoid refreshing package list without upgrading the system. It is, therefore, recommended to run. To install a specific package from repositories including required dependencies, issue command below in your terminal:. It will automatically detect required dependencies and install them as well. To install a package already downloaded onto the system. It should have extension pkg. My Pacman and yaourt Alias list.
