# docker_image (Resource)
|
|
|
|
Pulls a Docker image to a given Docker host from a Docker Registry.
|
|
This resource will *not* pull new layers of the image automatically unless used in conjunction with [docker_registry_image](registry_image.md) data source to update the `pull_triggers` field.
|
|
|
|
## Example Usage
|
|
|
|
### Basic
|
|
|
|
Finds and downloads the latest `ubuntu:precise` image but does not check
|
|
for further updates of the image
|
|
|
|
```terraform
|
|
resource "docker_image" "ubuntu" {
|
|
name = "ubuntu:precise"
|
|
}
|
|
```
|
|
|
|
### Dynamic updates
|
|
|
|
To be able to update an image dynamically when the `sha256` sum changes,
|
|
you need to use it in combination with `docker_registry_image` as follows:
|
|
|
|
```terraform
|
|
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]
|
|
}
|
|
```
|
|
|
|
### Build
|
|
|
|
You can also use the resource to build an image.
|
|
In this case the image "zoo" and "zoo:develop" are built.
|
|
|
|
```terraform
|
|
resource "docker_image" "zoo" {
|
|
name = "zoo"
|
|
build {
|
|
path = "."
|
|
tag = ["zoo:develop"]
|
|
build_arg = {
|
|
foo : "zoo"
|
|
}
|
|
label = {
|
|
author : "zoo"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|

## Schema
|
|
|
|
### Required
|
|
|
|
- **name** (String) The name of the Docker image, including any tags or SHA256 repo digests.
|
|
|
|
### Optional
|
|
|
|
- **build** (Block Set, Max: 1) Configuration to build an image. Please see [docker build command reference](https://docs.docker.com/engine/reference/commandline/build/#options) too. (see [below for nested schema](#nestedblock--build))
|
|
- **force_remove** (Boolean) If true, then the image is removed forcibly when the resource is destroyed.
|
|
- **id** (String) The ID of this resource.
|
|
- **keep_locally** (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_trigger** (String, Deprecated) A value which cause an image pull when changed
|
|
- **pull_triggers** (Set of String) 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-sources/registry_image.md).
|
|
|
|
### Read-Only
|
|
|
|
- **latest** (String, Deprecated) The ID of the image in the form of `sha256:<hash>` image digest. Do not confuse it with the default `latest` tag.
|
|
- **output** (String, Deprecated)
|
|
- **repo_digest** (String) The image sha256 digest in the form of `repo[:tag]@sha256:<hash>`.

### Nested Schema for `build`
|
|
|
|
Required:
|
|
|
|
- **path** (String) Context path
|
|
|
|
Optional:
|
|
|
|
- **build_arg** (Map of String) Set build-time variables
|
|
- **dockerfile** (String) Name of the Dockerfile. Defaults to `Dockerfile`.
|
|
- **force_remove** (Boolean) Always remove intermediate containers
|
|
- **label** (Map of String) Set metadata for an image
|
|
- **no_cache** (Boolean) Do not use cache when building the image
|
|
- **remove** (Boolean) Remove intermediate containers after a successful build. Defaults to `true`.
|
|
- **tag** (List of String) Name and optionally a tag in the 'name:tag' format
|
|
- **target** (String) Set the target build stage to build
