Provisioning commands

By having a Compose application file set up, we can now provision the application. The commands we will use are the following:

• build
• create
• up

Let’s take a look at them.

build

As seen previously, we do not need to build a Docker image and tag it manually before using it on Compose. Compose can build the image and use it for the application.

Issuing the build command creates the image:

$ docker compose build
=> => exporting layers                                                         0.0s
...
=> => naming to docker.io/library/chapter4_task manager        0.0s
$ docker images   ...
