Q:

Recreate containers with no downtime in docker-compose

I am using docker-compose for deploying several containers on the same host.  My images are built in Google Cloud Build and stored on gcr.io; I am not using docker-compose to build my images.
When I run docker-compose pull followed by docker-compose up -d, new containers are created for my images.  However, if I run docker ps in another tab, I observe that my containers go offline for a few seconds while the new ones are being created.
Is there a way to tell docker-compose to recreate and then restart the containers without any downtime?

A:

docker-compose up by itself does not support any way of deploying with zero downtime.

You'll need to implement your own blue/green deployment or have a look at kubernetes's rolling update:
