Pushing image with multiple tags using Node SDK

[chilly yarrow]

I am trying to publish docker image with latest and current version tag. Calling publish multiple time works but the pipeline also runs multiple time. I can can see that the application is being built two times.

Is there a way to publish image with multiple tags without executing the whole pipeline again ?

async function pipeline(client: Client) {
  // Create base image that has pnpm
  const base = () => {
    return client.container().from('node:18.15.0-alpine').withExec(['corepack', 'enable'])
  }
  
  //...

  // Create the final image that runs the application
  const image = base()
    .withExec(['apk', 'add', 'ffmpeg', 'yt-dlp'])
    .withWorkdir('/app')
    .withDirectory('node_modules', production.directory('node_modules'))
    .withDirectory('dist', build.directory('dist'))
    .withFile('package.json', build.file('package.json'))
    .withExposedPort(3000)
    .withEntrypoint(['node', 'dist/index.js'])

  // Publish the image to registry
  const password = client.setSecret('docker-hub-password', REGISTRY_PASSWORD)
  const authed = image.withRegistryAuth(REGISTRY_URL, REGISTRY_USERNAME, password)

  await authed.publish(`${REGISTRY_USERNAME}/botto:latest`)
  await authed.publish(`${REGISTRY_USERNAME}/botto:${info.version}`)
}

// Run the pipeline
await connect(pipeline, { LogOutput: process.stdout })

Is the second build faster (cached)?

[chilly yarrow]

Yes installing dependencies and build for 2nd time are fast.

I do this by pushing twice, all the steps are already cached so it doesn't actually build the app second times, and it runs super fast

Ok, so this is the expected behavior. You still see most of the log as if it were doing a lot of things, but the 2nd time, it just spits it without doing work, because the work has already been done.

Just to make sure, when I talked about the 2nd build, I was actually referring to the 2nd publish.
