rule - (Optional) Rule content, using conditional expressions to match user requests. When adding global configuration, this parameter does not need to be set. There are two usage scenarios: ● Match all incoming
Thecountproperty is also supported on Terraformmoduleblocks as well; as of Terraform 0.13 or later. So, this conditional deployment technique is not just available forresourceblocks, but alsoTerraform Moduleswith themoduleblock too! The following is an example of using this technique to implement th...
process_name- (Required, ForceNew) The name of the process. match_express_filter_relation- (Optional, ForceNew) The logical operator used between conditional expressions that are used to match instances. Valid values:all,and,or. match_express- (Optional, ForceNew, Set) The expressions used to...
Support for the "Removed" block has been added. Now automatically adds comment markers when a new line is inserted within a comment block. HCL syntax checks improved. Added support for the lifecycle meta-argument. 2023.3 Support for import block Support for loop that produces objects Completion...
In our example, the key b appears in both maps. Since map2 is the last map provided, its value for b ("blueberry") overrides the value from map1 ("banana"). Output the Result:Finally, we use the output block to display the merged_map. This helps verify that the merge function ...
Let's look at another example, where we have the following local block: locals { instances = { primary = { enabled = true region = "australiaeast" } secondary = { enabled = true region = "australiasoutheast" } tertiary = { enabled = true region = "australiacentral1" } } } This des...
For example: terraform plan -var 'name="John"' -var 'age=25' OR We can also use of the environment variables. For example: export TF_VAR_name="John" export TF_VAR_age=25 Varible Validation We can use the validation block to validate the variable value. It can be used to validate ...
If you wish to return an attribute from a conditional resource instance in your output then you'll need to write a conditional expression that tells Terraform which value to return when no VPC was created and therefore there's no valid id to return. For example: output "vpc_id" { ...
Thecountmeta-argument lets you create multiple instances of a resource from a single resource block. Refer to thecount meta-argument documentationfor examples. A common practice to conditionally create resources is to use thecountmeta-argument with aconditional expression. In the following example, T...
