<!-- vale Vale.Spelling = NO -->

98% of developers spend up to an hour every day waiting for builds to finish
([Incredibuild: 2022 Big Dev Build Times](https://www.incredibuild.com/survey-report-2022)).
Heavy, complex builds can become a major roadblock for development teams,
slowing down both local development and CI/CD pipelines.

<!-- vale Vale.Spelling = YES -->

Docker Build Cloud speeds up image build times to improve developer
productivity, reduce frustrations, and help you shorten the release cycle.

## Who’s this for?

- Anyone who wants to tackle common causes of slow image builds: limited local
resources, slow emulation, and lack of build collaboration across a team.
- Developers working on older machines who want to build faster.
- Development teams working on the same repository who want to cut wait times
with a shared cache.
- Developers performing multi-architecture builds who don’t want to spend hours
configuring and rebuilding for emulators.

<!-- break -->

## What you’ll learn

- Building container images faster locally and in CI
- Accelerating builds for multi-platform images
- Reusing pre-built images to expedite workflows

## Tools integration

Works well with Docker Compose, GitHub Actions, and other CI solutions

Docker Build Cloud is a service that lets you build container images faster,
both locally and in CI. Builds run on cloud infrastructure optimally
dimensioned for your workloads, with no configuration required. The service
uses a remote build cache, ensuring fast builds anywhere and for all team
members.

- Docker Build Cloud provides several benefits over local builds:
- Improved build speed
- Shared build cache
- Native multi-platform builds

There’s no need to worry about managing builders or infrastructure — simply
connect to your builders and start building. Each cloud builder provisioned to
an organization is completely isolated to a single Amazon EC2 instance, with a
dedicated EBS volume for build cache and encryption in transit. That means
there are no shared processes or data between cloud builders.

### Is Docker Build Cloud a standalone product or a part of Docker Desktop?

Docker Build Cloud is a service that can be used both with Docker Desktop and
standalone. It lets you build your container images faster, both locally and in
CI, with builds running on cloud infrastructure. The service uses a remote
build cache, ensuring fast builds anywhere and for all team members.

When used with Docker Desktop, the [Builds view](/desktop/use-desktop/builds/)
works with Docker Build Cloud out-of-the-box. It shows information about your
builds and those initiated by your team members using the same builder,
enabling collaborative troubleshooting.

To use Docker Build Cloud without Docker Desktop, you must
[download and install](/build-cloud/setup/#use-docker-build-cloud-without-docker-desktop)
a version of Buildx with support for Docker Build Cloud (the `cloud` driver).
If you plan on building with Docker Build Cloud using the `docker compose
build` command, you also need a version of Docker Compose that supports Docker
Build Cloud.

### How does Docker Build Cloud work with Docker Compose?

Docker Compose works out of the box with Docker Build Cloud. Install the Docker
Build Cloud-compatible client (buildx) and it works with both commands.

### How many minutes are included in Docker Build Cloud Team plans?

You receive 200 minutes per month per purchased seat. If you are also a Docker
subscriber (Personal, Pro, Team, Business), you will also receive your included
build minutes from that plan.

For example, if a Docker Team customer purchases 5 Build Cloud Team seats, they
will have 400 minutes from their Docker Team plan plus 1000 minutes (200 min/mo
* 5 seats) for a total of 1400 minutes per month.

### I’m a Docker personal user. Can I try Docker Build Cloud?

Docker subscribers (Pro, Team, Business) receive a set number of minutes each
month, shared across the account, to use Build Cloud.

If you do not have a Docker subscription, you may sign up for a free Personal
account and get 50 minutes per month. Personal accounts are limited to a single
user.

For teams to receive the shared cache benefit, they must either be on a Docker
Team, Docker Business, or paid Build Cloud Team plan. You may buy a month of
Build Cloud Team for the number of seats testing.

### Does Docker Build Cloud support CI platforms? Does it work with GitHub Actions?

Yes, Docker Build Cloud can be used with various CI platforms including GitHub
Actions, CircleCI, Jenkins, and others. It can speed up your build pipelines,
which means less time spent waiting and context switching.

Docker Build Cloud can be used with GitHub Actions to automate your build,
test, and deployment pipeline. Docker provides a set of official GitHub Actions
that you can use in your workflows.

Using GitHub Actions with Docker Build Cloud is straightforward. With a
one-line change in your GitHub Actions configuration, everything else stays the
same. You don't need to create new pipelines. Learn more in the [CI
documentation](/build-cloud/ci/) for Docker Build Cloud.

Developers face challenges with multi-container Docker applications, including
complex configuration, dependency management, and maintaining consistent
environments. Networking, resource allocation, data persistence, logging, and
monitoring add to the difficulty. Security concerns and troubleshooting issues
further complicate the process, requiring effective tools and practices for
efficient management.

Docker Compose solves the problem of managing multi-container Docker
applications by providing a simple way to define, configure, and run all the
containers needed for an application using a single YAML file. This approach
helps developers to easily set up, share, and maintain consistent development,
testing, and production environments, ensuring that complex applications can be
deployed with all their dependencies and services properly configured and
orchestrated.

<!-- break -->

## Who’s this for?

- Developers and DevOps engineers who need to define, manage, and orchestrate
multi-container Docker applications efficiently across multiple environments.
- Development teams that want to increase productivity by streamlining
development workflows and reducing setup time.

## Tools integration

Works well with Docker CLI, CI/CD tools, and container orchestration tools.

## Modules

{{< accordion large=true title=`Why Docker Compose?` icon=`play_circle` >}}

Docker Compose is an essential tool for defining and running multi-container
Docker applications. Docker Compose simplifies the Docker experience, making it
easier for developers to create, manage, and deploy applications by using YAML
files to configure application services.

Docker Compose provides several benefits:

- Lets you define multi-container applications in a single YAML file.
- Ensures consistent environments across development, testing, and production.
- Manages the startup and linking of multiple containers effortlessly.
- Streamlines development workflows and reduces setup time.
- Ensures that each service runs in its own container, avoiding conflicts.

### Do I need to maintain a separate Compose file for my development, testing, and staging environments?

You don't necessarily need to maintain entirely separate Compose files for your
development, testing, and staging environments. You can define all your
services in a single Compose file (`compose.yml`). You can use profiles to
group service configurations specific to each environment (`dev`, `test`,
`staging`).

When you need to spin up an environment, you can activate the corresponding
profiles. For example, to set up the development environment:

```console
$ docker compose --profile dev up
```

This command starts only the services associated with the `dev` profile,
leaving the rest inactive.

For more information on using profiles, see [Using profiles with
Compose](/compose/profiles/).

### How can I enforce the database service to start up before the frontend service?

Docker Compose ensures services start in a specific order by using the
`depends_on` property. This tells Compose to start the database service before
even attempting to launch the frontend service. This is crucial since
applications often rely on databases being ready for connections.

However, `depends_on` only guarantees the order, not that the database is fully
initialized. For a more robust approach, especially if your application relies
on a prepared database (e.g., after migrations), consider [health
checks](/reference/compose-file/services.md#healthcheck). Here, you can
configure the frontend to wait until the database passes its health check
before starting. This ensures the database is not only up but also ready to
handle requests.

For more information on setting the startup order of your services, see
[Control startup and shutdown order in Compose](/compose/startup-order/).

### Can I use Compose to build a Docker image?

Yes, you can use Docker Compose to build Docker images. Docker Compose is a
tool for defining and running multi-container applications. Even if your
application isn't a multi-container application, Docker Compose can make it
easier to run by defining all the `docker run` options in a file.

To use Compose, you need a `compose.yml` file. In this file, you can specify
the build context and Dockerfile for each service. When you run the command
`docker compose up --build`, Docker Compose will build the images for each
service and then start the containers.

For more information on building Docker images using Compose, see the [Compose
Build Specification](/compose/compose-file/build/).

### What is the difference between Docker Compose and Dockerfile?

A Dockerfile provides instructions to build a container image while a Compose
file defines your running containers. Quite often, a Compose file references a
Dockerfile to build an image to use for a particular service.

### What is the difference between the `docker compose up` and `docker compose run` commands?

The `docker compose up` command creates and starts all your services. It's
perfect for launching your development environment or running the entire
application. The `docker compose run` command focuses on individual services.
It starts a specified service along with its dependencies, allowing you to run
tests or perform one-off tasks within that container.
