Visualizing Docker Compose dependencies as a graph

Running docker compose alpha viz reads the depends_on settings in compose.yaml and allows you to visualize them as a graph.

$ docker compose alpha viz
viz command is EXPERIMENTAL
digraph "tmp" {
        layout=dot;
        "db" [style="filled" label=<<font point-size="15">db</font>>];
        "proxy" [style="filled" label=<<font point-size="15">proxy</font>>];
        "backend" [style="filled" label=<<font point-size="15">backend</font>>];

        "proxy" -> "backend";
        "backend" -> "db";
}

On Sixel-compatible terminals, you can output an image by piping the output as Compose → Graphviz → PNG -> Sixel.

docker compose alpha viz | dot -Tpng | img2sixel
