A simple command-line tool that constructs a DOT graph of service and volume dependencies within a given set of docker-compose files.
❯ go run main.go examples/simple.yaml
digraph compose {
graph [fontname = "arial"];
node [fontname = "arial"];
edge [fontname = "arial" color = "/greys8/8"];

label = "simple.yaml"
shape = "box"
