From 7c64b560dc54634e680556e683d6fa35ef5c0f08 Mon Sep 17 00:00:00 2001 From: claude Date: Sat, 20 Jun 2026 02:15:00 +0000 Subject: [PATCH] feat(cli): add commit command to snapshot running bottle state Adds `./cli.py commit []` which runs `docker commit` on the active agent container and stores the resulting image tag in per-bottle state. The next `./cli.py resume ` automatically boots from the committed snapshot instead of rebuilding from the Dockerfile, preserving all in-container state across restarts and migrations. - bottle_state: add write_committed_image / read_committed_image helpers - docker/util: add commit_container wrapper around `docker commit` - docker/launch: check for a committed image before the Dockerfile build step; fall back to normal build if the image is absent from the daemon - cli/commit: new command with interactive slug picker; errors clearly on non-Docker backends - 50 new unit tests covering all paths Co-Authored-By: Claude Sonnet 4.6 --- bot_bottle/backend/docker/launch.py | 23 +- bot_bottle/backend/docker/util.py | 15 ++ bot_bottle/bottle_state.py | 30 +++ bot_bottle/cli/__init__.py | 5 +- bot_bottle/cli/commit.py | 75 +++++++ docs/prds/prd-new-commit-bottle-state.md | 136 ++++++++++++ tests/unit/test_bottle_state.py | 51 +++++ tests/unit/test_cli_commit.py | 192 +++++++++++++++++ .../test_docker_launch_committed_image.py | 200 ++++++++++++++++++ tests/unit/test_docker_util_image.py | 41 ++++ 10 files changed, 761 insertions(+), 7 deletions(-) create mode 100644 bot_bottle/cli/commit.py create mode 100644 docs/prds/prd-new-commit-bottle-state.md create mode 100644 tests/unit/test_cli_commit.py create mode 100644 tests/unit/test_docker_launch_committed_image.py diff --git a/bot_bottle/backend/docker/launch.py b/bot_bottle/backend/docker/launch.py index b247e1e..b582b44 100644 --- a/bot_bottle/backend/docker/launch.py +++ b/bot_bottle/backend/docker/launch.py @@ -47,6 +47,7 @@ from ...bottle_state import ( bottle_state_dir, egress_state_dir, git_gate_state_dir, + read_committed_image, ) from .compose import ( bottle_plan_to_compose, @@ -91,12 +92,22 @@ def launch( ) try: - # Step 1: agent image build.
