Dev Error DB

Error category

Docker Errors and Fixes

Fix Docker daemon, Docker Compose, image pull, container runtime, storage, networking, and build errors in local development and CI environments.

This Docker troubleshooting hub collects real error signatures, quick fixes, common causes, and step-by-step debugging paths for developers who need a practical answer instead of a broad overview.

65 crawlable articles in this category. 40 additional records are indexed in JSON only (no standalone HTML route).

Browse Docker records in the data catalog — search JSON index entries, including data-only records without standalone HTML guides.

Troubleshooting overview

Start by matching the exact error message, then check the technology, environment, credentials, network path, and deployment context. The pages below are grouped so you can move from broad Docker symptoms to specific root-cause families without relying on client-side search.

Evidence labels are derived at build time from each Markdown record. Source-backed entries have public URLs under a Sources checked section, while partial-source entries expose public links without a complete source block.

Docker diagnostic workflow

  1. Copy the exact error signature and compare it with the page title, code block, and technology label.
  2. Check whether the failure is local, CI-only, deployment-only, provider-side, or account-specific.
  3. Collect non-secret versions, configuration names, request IDs, and timestamps before making changes.
  4. Review source-backed or partial-source pages first when the issue might depend on provider behavior or version-specific bugs.
  5. Apply the smallest reversible fix and rerun the same failing action.

Common error types

  • cannot connect to daemon
  • pull rate limit
  • build failed
  • permission denied
  • port already allocated
  • container exited

Common causes

  • Source: github.com/devcontainers/features/issues/1662 (updated 2026-05-22). Breaking change in devcontainer docker-in-docker feature v2/v3 on new Ubuntu/Docker versions. Blocks containerized dev workflows for teams relying on official Microsoft devcontainers image. Production-facing dev environment issue. (1 page)
  • Docker daemon troubleshooting docs document 'Cannot connect to the Docker daemon' as a top issue with multiple sub-scenarios. The covered-errors list has generic 'cannot connect to daemon' but does not cover the specific rootless-mode socket path (/run/user/<uid>/docker.sock) or systemd user-service timing conflicts which cause distinct troubleshooting paths. (1 page)
  • Deadends.dev provides detailed analysis showing fix rates 92%-96%, identifying stale containers and host processes as root causes. Moby GitHub issue #52092 reproduces the bug even with no visible containers. Netdata and multiple guides document the pattern. Category mapping: Docker → Docker. (1 page)
  • Google search user query suggestion (yearly range) indicates active discussions around Docker 29 breaking changes. Docker 29 introduces new minimum API version requirements; users upgrading see 'client version X is too new max supported API version is Y' errors. This blocks container deployments on servers/CI pipelines running older Docker versions. Known P0 technology category (Docker). Breaking API changes have high commercial impact for teams managing heterogeneous Docker environments. (1 page)
  • GitHub moby/moby issue #52578 (created 2026-05-07). Docker daemon dies with Go runtime panic. Critical for Docker users — complete runtime outage. Not in covered-errors (which only list general 'daemon not running'). This is a version-specific crash with clear stack trace. Category: Docker. (1 page)
  • GitHub issue moby/moby#52578: Docker daemon v29.4.1 crashes with panic in go-digest.Algorithm.Hash(). Stack trace points to Go stdlib crypto package. 9 comments, created 2026-05-07. Production-critical runtime crash with clear stack trace. Known regression in 29.4.x series. (1 page)

Latest pages in this category

Representative source-backed errors

These entries include public source URLs in the imported page body. Use them first when you need evidence for provider behavior, SDK regressions, or version-specific failures.

Safe debugging checklist

  • Do not paste API keys, tokens, cookies, private repository snippets, or customer data into public issues.
  • Keep a rollback path before changing credentials, billing limits, DNS, CI secrets, or production deploy settings.
  • Prefer official documentation and source-backed entries over broad guesses when the error affects paid APIs or production deploys.
