// A DAG is the basic unit of programming in dagger.
|
|
// It is a special kind of program which runs as a pipeline of computing nodes running in parallel,
|
|
// instead of a sequence of operations to be run by a single node.
|
|
//
|
|
// It is a powerful way to automate various parts of an application delivery workflow:
|
|
// build, test, deploy, generate configuration, enforce policies, publish artifacts, etc.
|
|
//
|
|
// The DAG architecture has many benefits:
|
|
// - Because DAGs are made of nodes executing in parallel, they are easy to scale.
|
|
// - Because all inputs and outputs are snapshotted and content-addressed, DAGs
|
|
// can easily be made repeatable, can be cached aggressively, and can be replayed
|
|
// at will.
|
|
// - Because nodes are executed by the same container engine as docker-build, DAGs
|
|
// can be developed using any language or technology capable of running in a docker.
|
|
// Dockerfiles and docker images are natively supported for maximum compatibility.
|
|
//
|
|
// - Because DAGs are programmed declaratively with a powerful configuration language,
|
|
// they are much easier to test, debug and refactor than traditional programming languages.
|
|
//
|
|
// To execute a DAG, the dagger runtime JIT-compiles it to a low-level format called
|
|
// llb, and executes it with buildkit.
|
|
// Think of buildkit as a specialized VM for running compute graphs; and dagger as
|
|
// a complete programming environment for that VM.
|
|
//
|
|
// The tradeoff for all those wonderful features is that a DAG architecture cannot be used
|
|
// for all software: only software than can be run as a pipeline.
|
|
//
|
|
|
|
// A dagger component is a configuration value augmented
|
|
// by scripts defining how to compute it, present it to a user,
|
|
// encrypt it, etc.
