From: Robert Wlodarczyk <robert@simplicityguy.com>
Date: Sat, 18 Feb 2023 18:42:20 -0800
Subject: [PATCH 29/83] feat: Major Updates - removed support for `projects` as
 the feature was very incomplete and it served little purpose - added support
 for common settings between jobs using `~~shared-settings` as a key in the
 config - cleaned up some items that have long bugged me   - better reuse of
 code   - better variable naming   - improved flow and readability   -
 formatting to the logs

 ## How to use
 
+### Docker Group ID Configuration
+
+This container needs to access the Docker socket to manage other containers. To do this, the `docker` user inside the container must have the same group ID (GID) as the `docker` group on the host system.
+
+By default, the Dockerfile uses GID 999, which is common for the `docker` group on many systems. If your host system uses a different GID, you need to specify it during the build:
+
+```bash
+# Find your host's docker group ID
+getent group docker | cut -d: -f3
+# Or alternatively
+stat -c '%g' /var/run/docker.sock
+
+# Then build with the correct GID
+docker build --build-arg DOCKER_GID=<your_docker_gid> -t crontab .
+```
+
+If you encounter the error `failed switching to "docker": operation not permitted`, it means the GIDs don't match. Rebuild the image with the correct GID.
+

+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is `docker-crontab`, a Docker-based cron job scheduler that allows running complex cron jobs in other containers. It's a lightweight alternative to mcuadros/ofelia with enterprise features.
+
+## Key Architecture
+
+### Core Components
+
+- **Dockerfile**: Multi-stage build using Alpine Linux base with Docker-in-Docker capability
+
+  - Builder stage: Downloads and compresses `rq` tool for config parsing
+  - Release stage: Based on `docker:dind-alpine` with cron and Docker client
+  - Uses `su-exec` for proper user privilege handling
+  - Configurable Docker group ID via `DOCKER_GID` build arg (default: 999)
+
+- **entrypoint.sh**: Main orchestration script that:
+
+  - Normalizes config files (JSON/YAML/TOML) using `rq` and `jq`
+  - Processes shared settings via `~~shared-settings` key
+  - Generates crontab entries and executable scripts
+  - Supports both `image` (docker run) and `container` (docker exec) execution modes
+  - Handles trigger chains and onstart commands
+
+### Configuration System
+
+- Supports JSON, YAML, and TOML config formats
+- Config can be array or mapping (top-level keys ignored for organization)
+- Special `~~shared-settings` key for shared configuration
+- Key fields: `schedule`, `command`, `image`/`container`, `dockerargs`, `trigger`, `onstart`
+- Schedule supports standard crontab syntax plus shortcuts (@hourly, @daily, @every 2m, etc.)
+- Additional fields: `comment`, `name`, `environment`, `expose`, `networks`, `ports`, `volumes`
+
+### Job Execution Flow
+
+1. Config normalization: All formats converted to working JSON
+1. Script generation: Each job becomes executable shell script in `/opt/crontab/jobs/`
+1. Crontab creation: Standard crontab file generated with proper scheduling
+1. Trigger processing: Post-job triggers executed in sequence
+1. Onstart handling: Jobs marked with `onstart: true` run immediately
+
+## Development Commands
+
+### Building
+
+```bash
+# Basic build
+docker build -t crontab .
+
+# Build with custom Docker group ID
+docker build --build-arg DOCKER_GID=$(stat -c '%g' /var/run/docker.sock) -t crontab .
+```
+
+### Running
+
+```bash
+# Command line execution
+docker run -d \
+    -v /var/run/docker.sock:/var/run/docker.sock:ro \
+    -v ./config-samples/config.sample.json:/opt/crontab/config.json:ro \
+    -v ./logs:/var/log/crontab:rw \
+    crontab
+
+# With host directory for persistent config/logs
+# Container will create directories with proper permissions
+docker run -d \
+    -v /var/run/docker.sock:/var/run/docker.sock:ro \
+    -v $PWD/crontab-config:/opt/crontab:rw \
+    -v $PWD/crontab-logs:/var/log/crontab:rw \
+    crontab
+
+# Docker Compose
+docker-compose up
+```
+
+### Testing
+
+```bash
+# Test with sample configuration
+docker run -d \
+    -v /var/run/docker.sock:/var/run/docker.sock:ro \
+    -v ./config-samples/config.sample.json:/opt/crontab/config.json:ro \
+    crontab
+
+# Debug mode - view generated crontab and scripts
+docker run --rm \
+    -v /var/run/docker.sock:/var/run/docker.sock:ro \
+    -v ./config-samples/config.sample.json:/opt/crontab/config.json:ro \
+    -e TEST_MODE=1 \
+    crontab bash -c "cat /tmp/crontab-docker-testing/test && ls -la /tmp/crontab-docker-testing/jobs/"
+```
+
+The repository includes sample configurations in `config-samples/` for testing different scenarios.
+
+## Important Configuration Notes
+
+- **Docker Socket Access**: Container requires read-only access to `/var/run/docker.sock`
+- **User Permissions**: Uses `docker` user with configurable GID to match host Docker group
+- **Volume Mounts**: Config and log directories should be mounted as volumes
+- **Network Access**: For docker-compose usage, containers need network connectivity via `--network` in `dockerargs`
+
+## Troubleshooting
+
+### Common Issues
+
+- **"failed switching to 'docker': operation not permitted"**: Docker group GID mismatch
+
+  - Solution: Rebuild with correct GID using `--build-arg DOCKER_GID=$(stat -c '%g' /var/run/docker.sock)`
+
+- **"Permission denied" creating directories**: Volume mount permissions issue
+
+  - Solution: Ensure host directories have correct ownership before mounting
+  - Quick fix: `sudo chown -R $(id -u):$(getent group docker | cut -d: -f3) /path/to/host/directory`
+  - Or let container create directories (it runs as root initially, then drops privileges)
+
+- **Jobs not executing**: Check crontab generation and script permissions
+
+  - Debug: Use `TEST_MODE=1` environment variable to inspect generated files
+
+- **Container networking issues**: Ensure proper network configuration in `dockerargs`
+
+  - For docker-compose: Add `--network <compose_network_name>` to dockerargs
+
+### File Locations
+
+- Generated scripts: `/opt/crontab/jobs/`
+- Working config: `/opt/crontab/config.working.json`
+- Crontab file: `/etc/crontabs/docker`
+- Logs: Container stdout/stderr (configure external logging as needed)
+
+## Security Considerations
+
+- Container runs as non-root `docker` user for security
+- Docker socket access is read-only to prevent container escape
+- Uses `su-exec` for privilege dropping instead of `sudo`
+- Multi-stage build minimizes attack surface
+- SBOM and provenance generation enabled in CI/CD
+
+## CI/CD
+
+GitHub Actions workflow (`.github/workflows/build.yml`):
+
+- Builds on push to main and PRs
+- Multi-platform support (linux/amd64)
+- Publishes to GitHub Container Registry (`ghcr.io`)
+- Includes security scanning with SBOM and provenance
+- Discord notifications for build status
+- Weekly scheduled builds for base image security updates

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace -S flag with -s flag to run crond in single-user mode.
This prevents "can't set groups: Operation not permitted" errors
since su-exec already handles the user switching to docker user.

Subject: [PATCH 68/83] fix: filter out unsupported -s flag for BusyBox crond
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BusyBox v1.37.0 crond doesn't support the -s flag that was attempted
in previous versions. This fix adds argument filtering in entrypoint.sh
to gracefully handle and remove any -s flags passed to crond, preventing
the "unrecognized option: s" error.

The solution maintains all previous fixes including proper user switching
via su-exec and running crond as root for cron job execution.

Subject: [PATCH 72/83] fix: BusyBox crond crontab directory configuration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The issue was that BusyBox crond was trying to interpret subdirectories
in /opt/crontab as usernames. This fix:

- Installs the generated crontab to /etc/crontabs/docker where BusyBox
  expects user crontab files
- Updates the crond command to use /etc/crontabs instead of /opt/crontab
- Ensures proper permissions (600) on the crontab file

This resolves the "no such user" errors for 'crontab' and 'jobs' directories.

Subject: [PATCH 74/83] fix: use user-writable crontab directory for non-root
 execution
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolves permission error "cannot create regular file '/etc/crontabs/docker'"
by moving crontab files to /opt/crontab/crontabs/ owned by docker user.

Changes:
- Modified entrypoint.sh to write crontab to /opt/crontab/crontabs/docker
- Updated Dockerfile to create crontabs directory with docker:docker ownership
- Added SUID bit to /usr/bin/crontab for proper crontab management
- Changed CMD to use custom crontabs directory (-c /opt/crontab/crontabs)
- Removed root requirement for crond execution (now runs as docker user)
- Enhanced documentation with security model and troubleshooting sections
- Updated all file path references in CLAUDE.md and README.md

Security improvements:
- Container now runs crond as non-root docker user
- Privilege separation via su-exec (starts as root, drops to docker user)
- Better handling of read-only volume mounts

+## Architecture & Security
+
+### Security Model
+
+The container is designed with security best practices:
+
+- **Non-root execution**: Container runs as the `docker` user (not root) for security
+- **Privilege separation**: Starts as root to set up directories, then drops to `docker` user via `su-exec`
+- **Read-only Docker socket**: Docker socket is mounted read-only to prevent container escape
+- **User-writable directories**: Crontab and job files stored in `/opt/crontab/` owned by `docker` user
+- **SUID crontab**: The `crontab` command has SUID bit set for proper crontab file management
+
+### Directory Structure
+
+- `/opt/crontab/` - Main working directory (can be volume mounted)
+  - `config.json` (or `.yaml`, `.toml`) - Your configuration file
+  - `config.working.json` - Normalized configuration (auto-generated)
+  - `jobs/` - Generated shell scripts for each cron job
+  - `crontabs/` - Crontab files for BusyBox crond
+    - `docker` - Crontab file for the `docker` user
+
 ## How to use
 
 ### Docker Group ID Configuration
@@ -109,12 +130,78 @@ COPY config.json ${HOME_DIR}/
 
 ### Logrotate Dockerfile
 
+This example shows how to extend the crontab image for custom use cases:
+
 ```Dockerfile
-FROM registry.gitlab.com/simplicityguy/docker/crontab
+FROM ghcr.io/simplicityguy/crontab
 
 RUN apk add --no-cache logrotate
-RUN echo "*/5 *	* * *  /usr/sbin/logrotate /etc/logrotate.conf" >> /etc/crontabs/logrotate
 COPY logrotate.conf /etc/logrotate.conf
+# Use the config.json approach instead of manually editing crontab files
+COPY config.json ${HOME_DIR}/
+```
+
+## Troubleshooting
+
+### Permission Errors
+
+**Issue**: `failed switching to 'docker': operation not permitted`
+
+**Cause**: Docker group GID mismatch between host and container.
+
+**Solution**: Rebuild the image with the correct Docker group ID:
+
+```bash
+# Find your host's docker group ID
+stat -c '%g' /var/run/docker.sock
 
-CMD ["crond", "-f"]
+# Rebuild with the correct GID
+docker build --build-arg DOCKER_GID=$(stat -c '%g' /var/run/docker.sock) -t crontab .
 ```
+
+### Jobs Not Executing

+   docker exec <container> cat /opt/crontab/crontabs/docker
+   ```
+
+1. Verify job scripts exist:
+
+   ```bash
+   docker exec <container> ls -la /opt/crontab/jobs/
+   ```
+
+1. Check crond is running:
+
+   ```bash
+   docker exec <container> ps aux | grep crond
+   ```
+
+1. View container logs for cron execution output:
+
+   ```bash
+   docker logs <container>
+   ```
+
+### Directory Permission Issues
+
+**Issue**: Container can't create directories when using volume mounts.
+
+**Solution**: Ensure the host directory has correct permissions before mounting:
+
+```bash
+# Create directory and set ownership
+mkdir -p /path/to/crontab
+chown -R $(id -u):$(id -g) /path/to/crontab
+
+# Then run container with volume mount
+docker run -v /path/to/crontab:/opt/crontab:rw ...
+```
+
+Alternatively, let the container create the directories on first run (it starts as root, creates directories, then drops to `docker` user).

Subject: [PATCH 75/83] chore(ci): improve build workflow performance and
 security
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enhances CI/CD workflows with performance optimizations and security
improvements.

Changes:
- Add Docker build caching for faster builds (cache-from/cache-to with GitHub Actions cache)
- Update Discord notification action from v1.12.0 to v1.15.5
- Pin Discord action to commit SHA (b8381b25576cb341b2af39926ab42c5056cc44ed) for security
- Applied Discord action update to both build.yml and cleanup.yml workflows

Performance Impact:
- Build caching reduces rebuild time by reusing layers across workflow runs
- Cache stored in GitHub Actions cache with mode=max for optimal storage

Subject: [PATCH 77/83] feat(ci): add automated workflow for base image updates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements automated Docker base image update workflow that checks for
and creates PRs when base images are updated.

Features:
- Runs weekly on Mondays at 9am UTC
- Manual trigger via workflow_dispatch
- Checks alpine:latest and docker:dind-alpine for updates
- Builds test image to verify compatibility
- Creates PR with update details and digests
- Auto-assigns to SimplicityGuy with appropriate labels
- Discord notifications for workflow status

Workflow:
1. Check for base image updates by pulling latest versions
2. Compare digests to detect changes
3. Build test image with new base images
4. Create PR with automated documentation
5. Send Discord notification

Security:
- Uses commit SHA pinning for create-pull-request action
- Test build ensures compatibility before PR creation

Subject: [PATCH 80/83] feat(ci): improve Docker image cleanup workflow

Replace old cleanup workflow with improved implementation:
- Migrate from snok/container-retention-policy to dataaxiom/ghcr-cleanup-action
- Automatic package discovery (no hardcoded package names needed)
- More flexible retention policies (keep 2 most recent tagged images)
- Better handling of partial and untagged images
- Remove Discord notifications to reduce dependencies
- Maintain monthly cleanup schedule (15th at midnight UTC)
- Add manual workflow_dispatch trigger for on-demand cleanup

Subject: [PATCH 81/83] feat(ci): add multi-platform Docker build support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add support for linux/arm64, linux/arm/v7, and linux/arm/v6 platforms
- Increase job timeout from default to 90 minutes to accommodate
  multi-platform builds with QEMU emulation
- Update both Docker Buildx setup and build steps with new platforms

This enables the crontab image to run on:
- linux/amd64: 64-bit x86 (Intel/AMD)
- linux/arm64: 64-bit ARM (Raspberry Pi 4+, AWS Graviton)
- linux/arm/v7: 32-bit ARM v7 (Raspberry Pi 2/3)
- linux/arm/v6: 32-bit ARM v6 (Raspberry Pi Zero/1)

Subject: [PATCH 82/83] fix(ci): correct package name in image cleanup workflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cleanup workflow was failing with a 404 error because it was
looking for package "docker-crontab" (derived from repository name)
instead of the actual package name "crontab" (defined in build.yml).

Add explicit package parameter to match IMAGE_NAME from build workflow:
- Build workflow: IMAGE_NAME: ${{ github.actor }}/crontab
- Cleanup workflow: package: crontab

Fixes error:
  GET /users/SimplicityGuy/packages/container/docker-crontab/versions
  - 404 not found

Subject: [PATCH 83/83] feat(build): add multi-platform support for rq binary
 downloads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add automatic platform detection to download the correct rq binary for
each target architecture during Docker builds. This fixes builds for
ARM platforms (arm64, armv7, armv6) which were previously failing due
to hardcoded x86_64 binary.

Changes:
- Add TARGETPLATFORM, TARGETOS, TARGETARCH, TARGETVARIANT build args
- Implement platform mapping case statement:
  - linux/amd64 → x86_64-unknown-linux-musl
  - linux/arm64 → aarch64-unknown-linux-gnu
  - linux/arm/v7 → armv7-unknown-linux-gnueabihf
  - linux/arm/v6 → arm-unknown-linux-gnueabi
- Add graceful fallback to x86_64 for unknown platforms
- Update hadolint ignore to include SC2086 for shell expansion

This aligns the Dockerfile with the CI/CD workflow which builds for
linux/amd64, linux/arm64, linux/arm/v7, and linux/arm/v6 platforms.
