#Docker Compose

Commands that version every module of a stack on its own, build its image under a tag that means exactly one build, refuse to reuse a version or swallow a failed compile, and archive images by name and tag so versions never overwrite each other.

Three commands that build a full copy of production for one release — configuration from the repository, images from the registry, data from the latest backup — restore it in order, run the release's migrations against that data, and remove it without a trace.

The procedure that gives a new project its whole infrastructure from generators, in the order the stacks depend on each other: log first, then storage and broker, then the gateway, then the application — with the public steps kept manual.

Templates come from real stacks, and copies quietly carry their data, keys, open databases and root-owned paths. My database, object storage and application generators leave the old data, keys and access behind, and read each application's facts from the application itself.

Every project gets its own OpenTelemetry Collector, Elasticsearch and Kibana from one command, showing data on dashboards from the first start, by owning the data directory, starting services in the order they need, and keeping the official mappings on one node.

Opening a broker to browsers and devices on the internet is less about encryption than identity. Each entrance now accepts one kind of credential, every token is bound to its own name and addressed to this broker, and TLS ends in nginx.

Every new project needs a gateway, sign-in, and a first administrator before its backend exists. One generator command now builds that stack, working on first boot, by handling the values that fail silently when set by hand and a rerun that would keep the old database.

Retyping long Docker commands costs seconds, invites typos and taxes working memory. Ten short executables on PATH removed that cost; the interesting decisions were why not aliases, how to keep names guessable, and why one of them is 260 lines long.
