Nick Fagerlund	85d477aee9	website: Fix numerous links with redirects or broken anchors ... These links largely still go somewhere useful, but they have some kind of issue revealed by our new link checker: - Some of them point to a stale URL that redirects, and can be updated to the new destination. - Some of them point to anchors that don't exist (anymore?) in the destination. - Some of them end up redirecting unnecessarily due to how the server handles directory URLs without trailing slashes. Sorry, I know that's pointless, just, humor me for the time being so we can get our CI green. 😭 In a couple cases, I've added invisible anchors to destination pages, either to preserve an old habit or because the current anchors kind of suck due to being particularly long or meandering.	5 years ago

Martin Atkins	efe78b2910	main: new global option -chdir ... This new option is intended to address the previous inconsistencies where some older subcommands supported partially changing the target directory (where Terraform would use the new directory inconsistently) where newer commands did not support that override at all. Instead, now Terraform will accept a -chdir command at the start of the command line (before the subcommand) and will interpret it as a request to direct all actions that would normally be taken in the current working directory into the target directory instead. This is similar to options offered by some other similar tools, such as the -C option in "make". The new option is only accepted at the start of the command line (before the subcommand) as a way to reflect that it is a global command (not specific to a particular subcommand) and that it takes effect _before_ executing the subcommand. This also means it'll be forced to appear before any other command-specific arguments that take file paths, which hopefully communicates that those other arguments are interpreted relative to the overridden path. As a measure of pragmatism for existing uses, the path.cwd object in the Terraform language will continue to return the _original_ working directory (ignoring -chdir), in case that is important in some exceptional workflows. The path.root object gives the root module directory, which will always match the overriden working directory unless the user simultaneously uses one of the legacy directory override arguments, which is not a pattern we intend to support in the long run. As a first step down the deprecation path, this commit adjusts the documentation to de-emphasize the inconsistent old command line arguments, including specific guidance on what to use instead for the main three workflow commands, but all of those options remain supported in the same way as they were before. In a later commit we'll make those arguments produce a visible deprecation warning in Terraform's output, and then in an even later commit we'll remove them entirely so that -chdir is the single supported way to run Terraform from a directory other than the one containing the root module configuration.	6 years ago

Martin Atkins	89c2a61b41	website: Small corrections to the "plan" and "apply" command docs ... The "apply" documentation contained a simple typo, while the "plan" documentation contained outdated information about using "terraform plan PLANFILE" to view a plan. The latter is now a separate command entirely, since Terraform 0.12: "terraform show PLANFILE".	6 years ago
Martin Atkins	31a4b44d2e	backend/local: treat output changes as side-effects to be applied ... This is a baby-step towards an intended future where all Terraform actions which have side-effects in either remote objects or the Terraform state can go through the plan+apply workflow. This initial change is focused only on allowing plan+apply for changes to root module output values, so that these can be written into a new state snapshot (for consumption by terraform_remote_state elsewhere) without having to go outside of the primary workflow by running "terraform refresh". This is also better than "terraform refresh" because it gives an opportunity to review the proposed changes before applying them, as we're accustomed to with resource changes. The downside here is that Terraform Core was not designed to produce accurate changesets for root module outputs. Although we added a place for it in the plan model in Terraform 0.12, Terraform Core currently produces inaccurate changesets there which don't properly track the prior values. We're planning to rework Terraform Core's evaluation approach in a forthcoming release so it would itself be able to distinguish between the prior state and the planned new state to produce an accurate changeset, but this commit introduces a temporary stop-gap solution of implementing the logic up in the local backend code, where we can freeze a snapshot of the prior state before we take any other actions and then use that to produce an accurate output changeset to decide whether the plan has externally-visible side-effects and render any changes to output values. This temporary approach should be replaced by a more appropriately-placed solution in Terraform Core in a release, which should then allow further behaviors in similar vein, such as user-visible drift detection for resource instances.	6 years ago
Nick Fagerlund	a797152648	website: Remove extra copy of "Running Terraform in Automation", update links ... This document now lives at: - https://learn.hashicorp.com/terraform/development/running-terraform-in-automation ...and terraform.io has been redirecting to there for quite a while. This commit removes the extra copy so that the text of the two versions doesn't drift, and updates existing links to point to the new location.	6 years ago
Martin Atkins	c06675c616	command: New -compact-warnings option ... When warnings appear in isolation (not accompanied by an error) it's reasonable to want to defer resolving them for a while because they are not actually blocking immediate work. However, our warning messages tend to be long by default in order to include all of the necessary context to understand the implications of the warning, and that can make them overwhelming when combined with other output. As a compromise, this adds a new CLI option -compact-warnings which is supported for all the main operation commands and which uses a more compact format to print out warnings as long as they aren't also accompanied by errors. The default remains unchanged except that the threshold for consolidating warning messages is reduced to one so that we'll now only show one of each distinct warning summary. Full warning messages are always shown if there's at least one error included in the diagnostic set too, because in that case the warning message could contain additional context to help understand the error.	6 years ago

Martin Atkins	400038eda4	command: "terraform apply" uses interactive confirmation by default ... In the 0.10 release we added an opt-in mode where Terraform would prompt interactively for confirmation during apply. We made this opt-in to give those who wrap Terraform in automation some time to update their scripts to explicitly opt out of this behavior where appropriate. Here we switch the default so that a "terraform apply" with no arguments will -- if it computes a non-empty diff -- display the diff and wait for the user to type "yes" in similar vein to the "terraform destroy" command. This makes the commonly-used "terraform apply" a safe workflow for interactive use, so "terraform plan" is now mainly for use in automation where a separate planning step is used. The apply command remains non-interactive when given an explicit plan file. The previous behavior -- though not recommended -- can be obtained by explicitly setting the -auto-approve option on the apply command line, and indeed that is how all of the tests are updated here so that they can continue to run non-interactively.	9 years ago

Martin Atkins	a8c58b081c	core: -target option to also select resources in descendant modules ... Previously the behavior for -target when given a module address was to target only resources directly within that module, ignoring any resources defined in child modules. This behavior turned out to be counter-intuitive, since users expected the -target address to be interpreted hierarchically. We'll now use the new "Contains" function for addresses, which provides a hierarchical "containment" concept that is more consistent with user expectations. In particular, it allows module.foo to match module.foo.module.bar.aws_instance.baz, where before that would not have been true. Since Contains isn't commutative (unlike Equals) this requires some special handling for targeting specific indices. When given an argument like -target=aws_instance.foo[0], the initial graph construction (for both plan and refresh) is for the resource nodes from configuration, which have not yet been expanded to separate indexed instances. Thus we need to do the first pass of TargetsTransformer in mode where indices are ignored, with the work then completed by the DynamicExpand method which re-applies the TargetsTransformer in index-sensitive mode. This is a breaking change for anyone depending on the previous behavior of -target, since it will now select more resources than before. There is no way provided to obtain the previous behavior. Eventually we may support negative targeting, which could then combine with positive targets to regain the previous behavior as an explicit choice.	9 years ago
