tasks:
  default:
    desc: List available tasks
    cmds:
      - task --list
    silent: true

  build-image:
    desc: >-
      Build the quine-linux bootc container image, as root (under podman
      this lands in root's containers-storage, which bootc and
      bootc-image-builder read; under docker, the ISO tasks copy it over).
    cmds:
      - sudo {{.CONTAINER_RUNTIME}} build -t {{.IMAGE}} -f Containerfile .
    sources:
      - Containerfile
      - overlay/**/*
      - patches/**/*

  build-iso:
    desc: >-
      Build a bootable install ISO from the local quine-linux image, via
      bootc-image-builder. Output lands in {{.OUTPUT_DIR}}/bootiso/install.iso.
    deps: [build-image]
    cmds:
      - task: export-to-storage
        vars: { IMAGES: "{{.IMAGE}}" }

    generates:
      - "{{.OUTPUT_DIR}}/bootiso/install.iso"

  build-installer-image:
    desc: >-
      Build the patched-Anaconda installer-environment container (see
      installer/Containerfile and docs/patched-anaconda-installer.md). This
      is separate from the quine-linux OS image itself. Defaults to the
      {{.COPR_REPO}} COPR project; override with
      `task build-installer-image COPR_REPO=you/other-project`.
    cmds:
      - sudo {{.CONTAINER_RUNTIME}} build -t {{.INSTALLER_IMAGE}} --build-arg COPR_REPO={{.COPR_REPO}} -f installer/Containerfile installer/
    sources:
      - installer/Containerfile

  build-installer-iso:
    desc: >-
      Build a bootable install ISO using the patched-Anaconda installer
      image to install the quine-linux bootc image, via
      bootc-image-builder's `bootc-installer` type. Output lands in
      {{.OUTPUT_DIR}}/bootc-installer/install.iso. Uses the same COPR_REPO
      default/override as build-installer-image.
    deps: [build-image]
    cmds:

        vars: { COPR_REPO: "{{.COPR_REPO}}" }

    generates:
      - "{{.OUTPUT_DIR}}/bootc-installer/install.iso"

  export-to-storage:
    internal: true
    desc: >-
      Under docker, copy IMAGES (space-separated local tags) from the docker
      daemon into the containers-storage volume bootc-image-builder reads.
      No-op under podman, which builds straight into containers-storage.
    status:
      - '[ "{{.CONTAINER_RUNTIME}}" = podman ]'
    cmds:
      - for: { var: IMAGES }
        cmd: >-

  status:
    desc: Show current bootc deployment status (what's booted, what's staged/rollback).
    cmds:
      - bootc status

  test:stage:
    desc: >-
      Build the local image and stage it as the next-boot target on THIS
      machine (bootc switch, no reboot yet). This is the fast way to test a
      change -- especially the CS8409 mic-fix kernel module -- against the
      real running system without building an ISO or reinstalling anything.
      Reboot separately when ready: `task test:boot`, or `sudo systemctl reboot`.
    deps: [build-image]
    cmds:
      # bootc reads the host's own containers-storage, i.e. podman's (which
      # every bootc host ships), so a docker-built image is loaded into it.
      - cmd: sudo docker save {{.IMAGE}} | sudo podman load
        platforms: [linux]
        if: '[ "{{.CONTAINER_RUNTIME}}" != podman ]'
      - sudo bootc switch --transport containers-storage localhost/{{.IMAGE}}
      - bootc status --booted
      - echo "Staged localhost/{{.IMAGE}} for next boot. Run task test:boot when ready to reboot into it."

  test:boot:
    desc: Stage the local image (if not already) and reboot into it now.
    prompt: This will reboot this machine into the locally-built {{.IMAGE}} image. Continue?
    deps: [test:stage]
    cmds:
      - sudo systemctl reboot

  revert:
    desc: >-
      Roll back to the previously-booted deployment and reboot into it --
      undoes a `test:boot` switch (or any other deployment change) if
      something's wrong. Safe even if nothing was ever switched: bootc/
      rpm-ostree always keep the prior deployment around for exactly this.
    prompt: This will reboot this machine back into the previous deployment. Continue?
    cmds:
      - sudo bootc rollback
      - sudo systemctl reboot
