»Command: terraform providers mirror
terraform providers mirror command downloads the providers required
for the current configuration and copies them into a directory in the local
In normal use,
terraform init will automatically download needed providers
from provider registries as part of initializing the current working directory.
Sometimes Terraform is running in an environment where that isn't possible,
such as on an isolated network without access to the Terraform Registry. In
explicit installation method configuration
allows you to configure Terraform, when running on a particular system, to
consult only a local filesystem directory where you've created a local mirror
of the necessary plugins, and to skip accessing the upstream registry at all.
terraform providers mirror command can automatically populate a directory
that will be used as a local filesystem mirror in the provider installation
terraform providers mirror is available only in Terraform v0.13 or later.
terraform providers mirror [options] <target-dir>
A single target directory is required. Terraform will create under that
directory the path structure that is expected for filesystem-based provider
plugin mirrors, populating it with
.zip files containing the plugins
Terraform will also generate various
.json index files which contain suitable
responses to implement
the network mirror protocol,
if you upload the resulting directory to a static website host. Terraform
ignores those index files when using the directory as a filesystem mirror,
because the directory entries themselves are authoritative in that case.
This command supports the following additional option:
-platform=OS_ARCH- Choose which target platform to build a mirror for. By default Terraform will obtain plugin packages suitable for the platform where you run this command. Use this flag multiple times to include packages for multiple target systems.
Target platform names consist of an operating system and a CPU architecture. For example,
linux_amd64selects the Linux operating system running on an AMD64 or x86_64 CPU.
You can run
terraform providers mirror again on an existing mirror directory
to update it with new packages. For example, you can add packages for a new
target platform by re-running the command with the desired new
option, and it will place the packages for that new platform without removing
packages you previously downloaded, merging the resulting set of packages
together to update the JSON index files.
