# Update a Deployment image with the APC API

<Note>
  The examples on this page show common ways to use the APC API — they're not a complete API reference. For the full, interactive API documentation for your installation, including every available query, mutation, and type, go to `https://houston.<your-base-domain>/v1`, and click on the **Docs** tab. See [Develop and test APC API queries](/docs/astro-private-cloud/v-2-x/houston-api-develop-test) for more on using the built-in GraphQL explorer.
</Note>

You can run a GraphQL mutation to update the image in your Deployment after manually pushing the image to a custom registry. This can be useful for automating code deploys using CI/CD.

At a minimum, your mutation has to include the following:

```graphql wrap theme={null}
mutation updateDeploymentImage {
        updateDeploymentImage(
                releaseName: "<deployment-release-name>", # for example "analytics-dev"
                image: "<host>/<image-name>:<tag>",  # for example docker.io/cmart123/ap-airflow:test4
                runtimeVersion: "<runtime-version-number>" # for example "5.0.6"
        )
        {
                id
        }
}
```

Alternatively, you can run this same mutation using cURL:

```bash wrap theme={null}
curl 'https://houston.BASEDOMAIN/v1' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: <your-token>' \
  --data-binary '{"query":"mutation updateDeploymentImage {updateDeploymentImage(releaseName: \"<deployment-release-name>\", image: \"<host>/<image-name>:<tag>\",runtimeVersion: \"<runtime-version-number>\"){id}}"}'
```

For the full custom registry setup, see [Configure a custom registry for Deployment images](/docs/astro-private-cloud/v-2-x/custom-image-registry).
