I found some old threads back from 2020 about it not being possible, but there has been conflicting information as well. If adequate compute capacity is unavailable, the pipelines compete for resources, and developers have to wait longer to know the effects of their changes. You can list registered Task Definitions with: By default, your ECS service will only have a private IP, and would typically be exposed publicly via an ELB. In stage 3, we use the distroless Node.js 16 image as our base image, set the working directory to /app, copy the node_modules and dist folders from the previous stage to the working directory and set the default command to run the node dist/index.js command. ECR is versioned storage for Docker images on AWS. That's what it's for.
