mitchelldavis / NullResourceToVault.tf
Last active August 23, 2018 12:54
This Gist is a reference on how to use Terraform's null_resource to apply configuration to Vault when the configuration endpoint doesn't define all of the expected http methods. (GET, PUT, POST, DELETE)
resource "null_resource" "secret_tune" {
triggers {
config_content = "${sha512("${file("data/sys/mounts/secret/tune.json")}")}"
}
provisioner "local-exec" {
command = "curl -X POST -H \"X-VAULT-TOKEN:$VAULT_TOKEN\" -d '${file("data/sys/mounts/secret/tune.json")}' $VAULT_ADDR/v1/sys/mounts/secret/tune"
}
}
