Usage: terraform validate [options] [dir]
|
|
|
|
Validate the terraform files in a directory. Validation includes a
|
|
basic check of syntax as well as checking that all variables declared
|
|
in the configuration are specified in one of the possible ways:
|
|
|
|
-var foo=...
|
|
-var-file=foo.vars
|
|
TF_VAR_foo environment variable
|
|
terraform.tfvars
|
|
default value
|
|
|
|
If dir is not specified, then the current directory will be used.
|
|
|
|
Options:
|
|
|
|
-check-variables=true If set to true (default), the command will check
|
|
whether all required variables have been specified.
|
|
|
|
-no-color If specified, output won't contain any color.
|
|
|
|
-var 'foo=bar' Set a variable in the Terraform configuration. This
|
|
flag can be set multiple times.
|
|
|
|
-var-file=foo Set variables in the Terraform configuration from
|
|
a file. If "terraform.tfvars" is present, it will be
|
|
automatically loaded if this flag is not specified.
