Docker Processor

File: src/processors/docker.py | Priority: 31 | Name: docker

Handles Docker CLI and Docker Compose output. Supports global options (--context, -H, --host).

Supported Commands

Command	Strategy
docker ps	Drops CONTAINER ID and COMMAND columns. Groups by status (Running/Stopped). Collapses > 10 stopped containers. Detects Exited, Created, and Dead statuses
docker images	Filters out dangling <none> images (shows count). Drops IMAGE ID column
docker logs	Error-focused: keeps first 10 lines (startup), error blocks with context (2 lines before/after), last 20 lines (recent). Caps error lines at 50
docker pull/push	Strips layer-by-layer progress, keeps digest and final status
docker inspect	Parses JSON, extracts key fields (Id, Name, State, Config, NetworkSettings). Shows State details, Config image/cmd/env, network ports and IPs. Falls back to structure summary for unrecognized keys
docker stats	Keeps only the last block from streaming output (header + data rows). Static --no-stream output passes through
docker compose up	Keeps Created/Started/Running/Error lines, network/volume creation. Strips progress percentages and log output
docker compose down	Keeps Stopped/Removed lines and network/volume removal
docker compose build	Keeps service headers, build step headers, errors, and final result. Strips intermediate containers
docker compose ps	Same as docker ps
docker compose logs	Same as docker logs

Configuration

Parameter	Default	Description
docker_log_keep_head	10	Lines kept from start of logs
docker_log_keep_tail	20	Lines kept from end of logs

Note

docker build and docker compose build output is handled by the Build Output Processor (priority 25), which processes it before Docker (priority 31).
