# Build and push your Docker image

This step will walk you through building and pushing your Docker image to your container registry. This is useful to building custom images for your use case.

1. Clone the [docker-application-template](https://github.com/swanchain/docker-application-template):

```
git clone https://github.com/swanchain/docker-application-template.git
```

2. Navigate to the root of the cloned repo:

```
cd docker-application-template
```

3. Build the Docker image (example: filswan/helloworld:v1.0):

```
docker build --platform linux/amd64 --tag <username>/<repo>:<tag> .
```

4. Push your container registry:

```
docker push <username>/<repo>:<tag>
```

> Note: After completing the above process, you can view the image information on the [docker hub](https://hub.docker.com/repository/docker/filswan/helloworld/general), as shown below:&#x20;

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.lagrangedao.org/getting-started/build-and-push-your-docker-image.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
