Downloads and installs modules needed for the configuration in the
|
|
current working directory.
|
|
|
|
This recursively downloads all modules needed, such as modules
|
|
imported by modules imported by the root and so on. If a module is
|
|
already downloaded, it will not be redownloaded or checked for updates
|
|
unless the -update flag is specified.
|
|
|
|
Module installation also happens automatically by default as part of
|
|
the "terraform init" command, so you should rarely need to run this
|
|
command separately.
|
|
|
|
Options:
|
|
|
|
-update Check already-downloaded modules for available updates
|
|
and install the newest versions available.
|
|
|
|
-no-color Disable text coloring in the output.
|
|
|
|
-test-directory=path Set the Terraform test directory, defaults to "tests".
