Milas Bowman 111ad3b039 fix(publish): add OCI 1.0 fallback support for AWS ECR
Currently, we publish Compose artifacts following the OCI 1.1
specification, which is still in the RC state.

As a result, not all registries support it yet. Most notably,
AWS ECR will reject certain OCI 1.1-compliant requests with
`405 Method Not Supported` with cryptic `Invalid JSON` errors.

This adds initial support for Compose to generate either an
OCI 1.0 or OCI 1.1 compatible manifest. Notably, the OCI 1.0
manifest will be missing the `application/vnd.docker.compose.project`
artifact type, as that does not exist in that version of the
spec. (Less importantly, it uses an empty `ImageConfig`
instead of the newer `application/vnd.oci.empty.v1+json` media
type for the config.)

Currently, this is not exposed as an option (via CLI flags or
env vars). By default, OCI 1.1 is used unless the registry
domain is `amazonaws.com`, which indicates an ECR registry, so
Compose will instead use OCI 1.0.

Moving forward, we should decide how much we want to expose/
support different OCI versions and investigate if there's a
more generic way to feature probe the registry to avoid
maintaining a hardcoded list of domains, which is both tedious
and insufficient.

Docker Compose v2

GitHub release PkgGoDev Build Status Go Report Card Codecov OpenSSF Scorecard Docker Compose

Docker Compose is a tool for running multi-container applications on Docker defined using the Compose file format. A Compose file is used to define how one or more containers that make up your application are configured. Once you have a Compose file, you can create and start your application with a single command: docker compose up.

Where to get Docker Compose

Windows and macOS

Docker Compose is included in Docker Desktop for Windows and macOS.

Linux

You can download Docker Compose binaries from the release page on this repository.

Rename the relevant binary for your OS to docker-compose and copy it to $HOME/.docker/cli-plugins

Or copy it into one of these folders to install it system-wide:

  • /usr/local/lib/docker/cli-plugins OR /usr/local/libexec/docker/cli-plugins
  • /usr/lib/docker/cli-plugins OR /usr/libexec/docker/cli-plugins

(might require making the downloaded file executable with chmod +x)

Quick Start

Using Docker Compose is a three-step process:

  1. Define your app's environment with a Dockerfile so it can be reproduced anywhere.
  2. Define the services that make up your app in compose.yaml so they can be run together in an isolated environment.
  3. Lastly, run docker compose up and Compose will start and run your entire app.

A Compose file looks like this:

services:
  web:
    build: .
    ports:
      - "5000:5000"
    volumes:
      - .:/code
  redis:
    image: redis
