From deab3ab45bf7ebc709a0fef62a434fac623c3812 Mon Sep 17 00:00:00 2001 From: felix068 Date: Sun, 5 Oct 2025 14:24:06 +0200 Subject: [PATCH] Add Docker images management feature MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds a comprehensive Docker images management interface to Dockge, allowing users to: - View all Docker images with details (repository, tag, ID, size, created date) - Pull images from Docker registries - Build images from Dockerfile content - Delete individual images - Prune all unused images - View Docker disk usage statistics (images, containers, volumes, build cache) - Search/filter images ## Backend Changes - Added 6 new socket event handlers in `docker-socket-handler.ts`: - `getDockerImageList`: List all images - `deleteDockerImage`: Remove an image by ID - `getDockerDiskUsage`: Get disk usage stats - `pullDockerImage`: Pull image from registry - `buildDockerImage`: Build from Dockerfile - `pruneDockerImages`: Remove unused images - All methods include proper error handling with real Docker error messages - Full JSDoc documentation for all methods ## Frontend Changes - New page: `Images.vue` with StackList-inspired design - Integrated search functionality - Progress indicators for pull/build operations - Dark theme support - Responsive layout ## Features - Real-time error messages from Docker (not generic errors) - Proper handling of images in use by containers - Progress bar for long operations (pull/build) - Warning dialogs for destructive operations - Consistent UI/UX with existing Dockge interface ## Translation - Added 23 new translation keys in `en.json` only - No other languages modified (as per contribution guidelines) All changes follow CONTRIBUTING.md guidelines: - 4-space indentation ✓ - camelCase for JS/TS ✓ - kebab-case for CSS ✓ - JSDoc documentation ✓ - No new dependencies ✓ - Consistent UI styling ✓ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../docker-socket-handler.ts | 248 ++++++++ frontend/src/lang/en.json | 41 +- frontend/src/layouts/Layout.vue | 6 + frontend/src/pages/Images.vue | 531 ++++++++++++++++++ frontend/src/router.ts | 9 + 5 files changed, 834 insertions(+), 1 deletion(-) create mode 100644 frontend/src/pages/Images.vue diff --git a/backend/agent-socket-handlers/docker-socket-handler.ts b/backend/agent-socket-handlers/docker-socket-handler.ts index 81746019..230185e8 100644 --- a/backend/agent-socket-handlers/docker-socket-handler.ts +++ b/backend/agent-socket-handlers/docker-socket-handler.ts @@ -3,6 +3,7 @@ import { DockgeServer } from "../dockge-server";
