⭐ Dockerfile support

[arlimus]

Start to add Dockerfile support. You can now:

cnquery ACTION docker file DOCKERFILE

Example:

cnquery shell docker file Dockerfile

cnquery scan docker file Dockerfile.dev

This exposes new keyworeds, which are attached to docker.file.

1. Commands

All instructions are accessible in a structured way. Please note that a Dockerfile may have multiple stages.

> docker.file.stages{*}
docker.file.stages: [
  0: {
    entrypoint: docker.file.run script="cnquery"
    add: []
    run: [
      0: docker.file.run script="apk update &&    apk add ca-certificates wget tar &&    rm -rf /var/cache/apk/*"
    ]
    from: docker.file.from name="root" image="alpine" tag="3.19"
    env: {}
    copy: [
      0: docker.file.addcopy src=[
        0: "cnquery"
      ] dst="/usr/local/bin"
    ]
    cmd: docker.file.run script="help"
  }
  1: {
    entrypoint: null
    add: []
...

2. Instructions

An alternative is to access low-level instructions. These are great if you just want to interact with all the instructions without thinking about their context.

> docker.file.instructions
docker.file.instructions: [
  0: {
    original: "FROM alpine:3.19 AS root"
  }
  1: {
    original: "RUN apk update &&    apk add ca-certificates wget tar &&    rm -rf /var/cache/apk/*"
  }
...

3. File access

Finally, a docker.file has the regular file resource embedded. This means you can use anything that is accessible in file (given that #3805 merges before this).

> docker.file.path
docker.file.file.path: "Dockerfile"
