Since this was just added and a new version hasn’t been cut, you could use the alpha build off this

<https://pypi.org/project/pulumi-docker/2.2.0a1590012385/>

Silly question, but I have to double check given the error above… is `docker` on your path?

I think I got it working now, it was the `env`

<@UTH0AMTQQ> I am working with the Alpha Image() class and having a hard time tieing the image_name for the Task Definition. Meaning within the `container_definition` it needs to be a supplied json string, which I build using `json.dumps()`, when referencing `image.image_name` I do not think the actual string value of `image_name` is being passed as ecr provides `Container.Image has invalid characters`, however locally the image was build successfully.

If I build it dynamically such as this, it works: `'image': '%s.dkr.ecr.%<http://s.amazonaws.com/%s/%s-ui:latest|s.amazonaws.com/%s/%s-ui:latest>' % (account.account_id, current.name, p_env, p_application )`  however I dont want to use a static tag, rather use the dynamic tag generated from pulumi.

I’m not sure I quite understand — can you please show me how you construct the JSON you’re trying to pass in?

Oh, I see you asked in the channel itself
