Node.js Dockerfile Generator (Multi-Stage, Alpine)

omnial/node-dockerfile-generator

Writes, with a language model, a multi-stage Dockerfile on an Alpine Node.js base image for a Node.js app built on the web framework you name. Returns the Dockerfile text, labels for its build stages, a rough image-size estimate, a list of security notes on the choices made, and recommended .dockerignore entries. The entry file, port and health check in the file are the model's assumptions; check them against your app.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/node-dockerfile-generator" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/node-dockerfile-generator" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/node-dockerfile-generator", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "omnial/node-dockerfile-generator", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
