The TTY renderer accumulated display-corruption fixes (truncation of details, then progress sizes, then task ids; timer alignment; rune-based measurement) that each patched one symptom of the same structural gap: nothing guaranteed a rendered line fits the terminal, and once a line wraps, cursor arithmetic desyncs and the block corrupts. Replace it with three separable units: - tty_model.go: pure event reducer with an injected clock, preserving first-parent-wins updates, monotonic progress and header counters - tty_layout.go: pure (model, size, now) -> lines function; all widths are measured in terminal cells (go-runewidth, so CJK is correct) on plain text before coloring, and every line is clipped to the terminal width by construction, status text included - tty_screen.go: diff-based repaint; unchanged rows are skipped, identical frames write nothing, a frame is a single Write; a shrinking terminal abandons the block instead of moving the cursor over reflowed rows The writer coordinates them behind a mutex and stops the refresh goroutine through context cancellation, so Done cannot block when the operation context was cancelled first (Ctrl-C during pull). The spinner frame is derived from the clock instead of advancing on every call, and truncation can no longer split multi-byte runes. Visual output is unchanged: the snapshot test reproduces the previous renderer's golden output character for character.

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.
Note
: About Docker Swarm Docker Swarm used to rely on the legacy compose file format but did not adopt the compose specification so is missing some of the recent enhancements in the compose syntax. After acquisition by Mirantis swarm isn't maintained by Docker Inc, and as such some Docker Compose features aren't accessible to swarm users.
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-pluginsOR/usr/local/libexec/docker/cli-plugins/usr/lib/docker/cli-pluginsOR/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:
- Define your app's environment with a
Dockerfileso it can be reproduced anywhere. - Define the services that make up your app in
compose.yamlso they can be run together in an isolated environment. - Lastly, run
docker compose upand 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
