#### Using updated images when rebuilding a workspace

To ensure that Coder uses an updated image when rebuilding a workspace, we
suggest that admins update the tag in the template (e.g., `my-image:v0.4.2` ->
`my-image:v0.4.3`) or digest (`my-image@sha256:[digest]` ->
`my-image@sha256:[new_digest]`).

Alternatively, if you're willing to wait for longer start times from Coder, you
can set the `imagePullPolicy` to `Always` in your Terraform template; when set,
Coder will check `image:tag` on every build and update if necessary:

```tf
resource "kubernetes_pod" "podName" {
spec {
container {
image_pull_policy = "Always"
}
}
}
```
