COPY ui /ui RUN npm run build

FROM alpine LABEL org.opencontainers.image.title="My extension" \ org.opencontainers.image.description="Your Desktop Extension Description" \ org.opencontainers.image.vendor="Awesome Inc." \ com.docker.desktop.extension.api.version="0.3.3" \ com.docker.desktop.extension.icon=" \ com.docker.extension.screenshots="" \ com.docker.extension.detailed-description="" \ com.docker.extension.publisher-url="" \ com.docker.extension.additional-urls="" \ com.docker.extension.changelog=""

&gt; Note
&gt;
&gt; In the example Dockerfile, you can see that the image label `com.docker.desktop.extension.icon` is set to an icon URL. The Extensions Marketplace displays this icon without installing the extension. The Dockerfile also includes `COPY docker.svg .` to copy an icon file inside the image. This second icon file is used to display the extension UI in the Dashboard, once the extension is installed.
