gcp functions
The functions in the gcp namespace interface with various Google Cloud Platform
APIs to make it possible for a template to render differently based on the GCP
environment and metadata.
Configuring GCP
A number of environment variables can be used to control how gomplate communicates with GCP APIs.
| Environment Variable | Description |
|---|---|
GCP_META_ENDPOINT |
(Default http://metadata.google.internal) Sets the base address of the instance metadata service. |
GCP_TIMEOUT |
(Default 500) Adjusts timeout for API requests, in milliseconds. |
gcp.Meta
Queries GCP Instance Metadata for information.
For times when running outside GCP, or when the metadata API can’t be reached, a default value can be provided.
Added in gomplate v3.8.0
