Usage: nomad-e2e provision <provider> <environment>
|
|
|
|
Uses terraform to provision a target test environment to use
|
|
for end-to-end testing.
|
|
|
|
The output is a list of environment variables used to configure
|
|
various api clients such as Nomad, Consul and Vault.

|
|
Provision Options:
|
|
|
|
-env-path
|
|
Sets the path for where to search for test environment configuration.
|
|
This defaults to './environments/'.
|
|
|
|
-nomad-binary
|
|
Sets the target nomad-binary to use when provisioning a nomad cluster.
|
|
The binary is retrieved by go-getter and can therefore be a local file
|
|
path, remote http url, or other support go-getter uri.
|
|
|
|
-destroy
|
|
If set, will destroy the target environment.
|
|
|
|
-tf-path
|
|
Sets the path for which terraform state files are stored. Defaults to
|
|
the current working directory.
