The Terraform language has some idiomatic style conventions, and we recommend you always follow them to ensure consistency between files and modules written by different teams. In addition, automatic formatting tools also need to conform to such conventions, and you can use terraform fmt for formatting.
Code constraint
Indent two spaces for each nesting level.
When multiple arguments with single-line values appear on consecutive lines at the same nesting level, align their equals signs:
ami = "abc123"
instance_type = "t2.micro"
When both arguments and blocks appear together inside a block body, place all of the arguments together at the top and then place nested blocks below them. Use one blank line to separate the arguments from the blocks.
Use blank lines to separate logical groups of arguments within a block.
For blocks that contain both arguments and "meta-arguments" (as defined by the Terraform language semantics), list meta-arguments first and separate them from other arguments with one blank line. Place meta-argument blocks last and separate them from other blocks with one blank line. For example:
resource "tencentclould_instance" "example" {
count = 2 # meta-argument first
ami = "abc123"
instance_type = "t2.micro"
network_interface {
# ...
}
lifecycle {
# meta-argument block last
create_before_destroy = true
}
}
Top-Level blocks should always be separated from one another by one blank line. Nested blocks should also be separated by blank lines, except when grouping together related blocks of the same type (like multiple provisioner blocks in a resource).
Avoid separating multiple blocks of the same type with other blocks of a different type, unless the block types are defined by semantics to form a family.
