Compose checker: a second pair of eyes on your docker-compose.yml
Paste your compose.yaml and get the weak spots named: unpinned images, databases on the proxy network, secrets in plain text, open ports.
Every rule here comes from the recipes on this site – checked against 57 Compose files with 88 services, all of which actually ran on a server. That is why most findings tell you how often our own corpus does it differently.
The checker is no substitute for thinking: it does not know your use case. A hint may be exactly right in your setup – then ignore it.
The check runs entirely in your browser – nothing is uploaded.
