It is useful to sometimes deploy only the task definition without re-building it. Say for example, you are debugging the task definition and just want to directly edit the `.ufo/output/hi-web.json` definition. You can accomplish this with the `ufo deploy` command. The `ufo deploy` command will deploy the task definition in `.ufo/output` unmodified. Example: ufo deploy hi-web The above command does the following: 1. register the `.ufo/output/hi-web.json` task definition to ECS untouched. 2. deploys it to ECS by updating the service The `ufo deploy` command does less than the `ufo ship` command. Typically, people use `ufo ship` over the `ufo deploy` command do everything in one step: 1. build the Docker image 2. register the ECS task definition 3. update the ECS service
