Gradle RequireDocker plugin

I am looking for help to develop this plugin. I have a lot of ideas, but I don't have enough time to implement them all. If you are interested, feel free to open an issue or a discussion to talk about it. Also, I will be happy to add you to the list of contributors. Thank you!

Integrate docker containers into your workflow. Require Docker containers to be running before executing a Gradle task and shutdown after.

With this plugin, you can require a Postgres container to be running before executing a Flyway migration and a JOOQ code generation or integration tests tasks. Plugin also maintains containers lifecycle, so you don't need to worry about stopping and removing containers after.

plugins {
    id("io.github.meiblorn.require-docker") version "x.y.z"
}

requireDocker {
    val jooq by requireDocker.specs.creating {
        val postgres by contaienrs.creating {
            image("postgres:latest")
            portBindings("5432:5432")
            envVars(
                "POSTGRES_PASSWORD" to "postgres",
                "POSTGRES_USER" to "postgres",
                "POSTGRES_DB" to "postgres",
            )
        }
    }
}

// Create Flyway migrations task
// This task creates schema and tables in the database
val jooqFlywayMigrate by tasks.creating {
    url = "jdbc:postgresql://localhost:5432/postgres"
    user = "postgres"
    password = "postgres"
}

val generateJooq by tasks.getting {
    // Declare a dependency on the jooqFlywayMigrate task
    // NOTE: JOOQ requires the database schema 
    //       to be created before generating the code
    dependsOn(jooqFlywayMigrate)
}

// Enforce containers to be running before 
// executing jooqFlywayMigrate and generateJooq tasks
requireDocker.spec("jooq") {
    requiredBy(jooqFlywayMigrate)
    requiredBy(generateJooq)
}

TODO:

• Publish plugin to Gradle Plugin Portal
• Add test coverage
• Add GitHub Actions workflow
• Add badges to README.md
• Add more samples
• Clean up code
  • Move Kotlin extensions to separate Gradle source set
  • Build internal task graph and then process it in a single place instead of iterating specs and containers in nested loops
  • Utilise dependency injection features of Gradle to simplify code
• Cover with unit tests
• Cover with integration tests
  • Check Docker client
  • Check Bmuschko's Gradle plugin conflicts
  • Check Spring Boot Gradle plugin conflicts
  • Check Micronaut Gradle plugin conflicts
• Add java docs
• Add docs (preferably using docusaurus)
