// terraform-bundle is a tool to create "bundle archives" that contain both
|
||
|
|
// a particular version of Terraform and a set of providers for use with it.
|
||
|
|
//
|
||
|
|
// Such bundles are useful for distributing a Terraform version and a set
|
||
|
|
// of providers to a system out-of-band, in situations where Terraform's
|
||
|
|
// auto-installer cannot be used due to firewall rules, "air-gapped" systems,
|
||
|
|
// etc.
|
||
|
|
//
|
||
|
|
// When using bundle archives, it's suggested to use a version numbering
|
||
|
|
// scheme that adds a suffix that identifies the archive as being a bundle,
|
||
|
|
// to make it easier to distinguish bundle archives from the normal separated
|
||
|
|
// release archives. This tool by default produces files with the following
|
||
|
|
// naming scheme:
|
||
|
|
//
|
||
|
|
// terraform_0.10.0-bundle2017070302_linux_amd64.zip
|
||
|
|
//
|
||
|
|
// The user is free to rename these files, since the archive filename has
|
||
|
|
// no significance to Terraform itself and the generated pseudo-version number
|
||
|
|
// is not referenced within the archive contents.
|
||
|
|
//
|
||
|
|
// If using such a bundle with an on-premises Terraform Enterprise installation,
|
||
|
|
// it's recommended to use the generated version number (or a modification
|
||
|
|
// thereof) as the tool version within Terraform Enterprise, so that
|
||
|
|
// bundle archives can be distinguished from official releases and from
|
||
|
|
// each other even if the same core Terraform version is used.
|
||
|
|
//
|
||
|
|
// Terraform providers in general release more often than core, so it is
|
||
|
|
// intended that this tool can be used to periodically upgrade providers
|
||
|
|
// within certain constraints and produce a new bundle containing these
|
||
|
|
// upgraded provider versions. A bundle archive can include multiple versions
|
||
|
|
// of the same provider, allowing configurations containing provider version
|
||
|
|
// constrants to be gradually migrated to newer versions.
