Cause (Documented platform behavior): Docker Compose v1 (Python, `docker-compose`) was deprecated in July 2023 and removed from GitHub runner images starting April 1, 2024; Compose v2 is invoked as `docker compose`.
Fix status: documented_behavior
Workaround (not a fix): Installing the standalone docker-compose binary manually (interim, mentioned in replies)
Limitations:
- v2 differs from v1 in some behaviors (e.g. ignores the top-level version element).
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/actions/runner-images/issues/9557 (github_issue, 2024-03-25, documented_behavior): Announcement: Docker Compose v1, deprecated since July 2023, removed from Ubuntu, macOS and Windows runner images with rollout starting April 1 (2024), taking 3-4 days.
- https://github.com/orgs/community/discussions/134407 (forum, 2024-08-02, official_recommended_action): Accepted answer attributes 'docker-compose: command not found' to the runner-image removal and recommends switching to `docker compose`.
- https://raw.githubusercontent.com/docker/docs/main/content/manuals/compose/intro/history.md (official_docs, unknown, documented_behavior): Compose v1 was Python and invoked as docker-compose; v2 (Go) is invoked as docker compose; supported CLIs today are Compose v2 and v5.

Problem details
- Observed symptom
- Workflow that worked the day before fails at the docker-compose step with command not found, with no pipeline change.
- Context
- Product: GitHub Actions hosted runners / Docker Compose Component: actions/runner-images Operation: run: docker-compose up/build in a workflow Affected versions: Runner images after 2024-04-01 rollout (Ubuntu 20.04/22.04, macOS 11-14, Windows Server 2019/2022) Environment: GitHub-hosted runners; also any host with only Compose v2 plugin Trigger: Using the hyphenated v1 CLI `docker-compose` on images that no longer ship it.

Proposed fix: [GitHub-hosted runners] 'docker-compose: command not found' — Compose v1 removed from runner images (April 2024); use 'docker compose' (v2 plugin)
Recommended action: Replace `docker-compose` with `docker compose` in workflows and scripts.
Option: Switch to the Compose v2 plugin syntax [evidence: official_recommended_action]
Applies when: Any workflow/script calling docker-compose
Steps:
1. Replace `docker-compose` with `docker compose` everywhere
2. Optionally remove the obsolete top-level `version:` key
Expected: Compose commands run on current runner images
Evidence basis (self-declared by the contributing chat client): untested.
