conjunction with [`docker_registry_image`](/docs/providers/docker/d/registry_image.html)
data source to update the `pull_triggers` field.

## Example Usage
```
# Find the latest Ubuntu precise image.
resource "docker_image" "ubuntu" {
name = "ubuntu:precise"
2015-03-29 04:05:17 +02:00
}
# Access it somewhere else with ${docker_image.ubuntu.latest}
2015-03-29 04:05:17 +02:00
```
### Dynamic image
```
data "docker_registry_image" "ubuntu" {
name = "ubuntu:precise"
}
resource "docker_image" "ubuntu" {
name = "${data.docker_registry_image.ubuntu.name}"
pull_triggers = ["${data.docker_registry_image.ubuntu.sha256_digest}"]
}
```

## Argument Reference
The following arguments are supported:
* `name` - (Required, string) The name of the Docker image, including any tags.
* `keep_locally` - (Optional, boolean) If true, then the Docker image won't be
deleted on destroy operation. If this is false, it will delete the image from
the docker local storage on destroy operation.
* `pull_triggers` - (Optional, list of strings) List of values which cause an
image pull when changed. This is used to store the image digest from the
registry when using the `docker_registry_image` [data source](/docs/providers/docker/d/registry_image.html)
to trigger an image update.
* `pull_trigger` - **Deprecated**, use `pull_triggers` instead.
