How do you rebuild images in Compose?

DockerJunior~1 min read

To rebuild images in Docker Compose, the --build flag is used.

The most common command:

bash

docker compose up --build

It rebuilds the images from the Dockerfile from scratch and starts the containers.

If the containers are already running, you can rebuild and restart them like this:

bash

docker compose up --build -d

An alternative is separate steps:

bash

docker compose build       # rebuild images
docker compose up -d       # bring up containers

The idea is simple: up is responsible for starting, build for rebuilding. The --build flag lets you do this in one step.
