pi-devbox no longer installs pi itself. The Dockerfile is now a thin
FROM joakimp/opencode-devbox:latest-with-pi (overridable via BASE_IMAGE),
inheriting pi + pi-toolkit + pi-extensions + pi-fork (fork) +
pi-observational-memory (recall) + the LAN-access helper + all base tooling
from the single source of truth. Eliminates the install-logic duplication
that drifted against opencode-devbox/Dockerfile.variant (decision #3).
Consequences (documented in CHANGELOG/AGENTS):
- The image now ALSO contains opencode (with-pi has INSTALL_OPENCODE=true).
A leaner pi-only image would need a dedicated pi-only variant upstream.
- Publish ordering: release opencode-devbox first so latest-with-pi carries
the target pi version, THEN tag this repo. The smoke test asserts
pi --version matches the tag (EXPECTED_PI_VERSION) and fails loudly if the
base is stale — turning the version coupling into an enforced ordering guard.
CI: drop PI_VERSION build-arg (Dockerfile installs nothing); keep tag->version
resolution to feed the smoke base-freshness guard. Smoke adds fork/recall
clone + node_modules + settings.json registration checks; size threshold
2200 -> 2900 MB (now tracks with-pi). Docs updated across README, AGENTS,
DOCKER_HUB, .env.example, docker-compose.
Belt-and-braces against transient registry-1.docker.io blips (rate
limits, brief 5xx, CDN flap). Replaces docker/build-push-action@v7 with
a shell: bash step that runs docker buildx build --push in a for-loop
with backoff (15s, 30s).
Does NOT mask deterministic failures: a true regression (e.g. the
cache-export 400 we hit 2026-05-23..28) fails all 3 attempts
identically and the job still fails by design. Orthogonal layer to
both cache-export disablement and the ci-release-watcher skill's
transient-rerun heuristic.
No image-side change.
pi 0.75.5 → 0.76.0 (published upstream 2026-05-27 20:03 UTC). First
pi-devbox release built against opencode-devbox base-latest carrying the
SSH ControlMaster bake-in (commit 668592d) and gitleaks (73a7f96) — both
inherited transparently with no Dockerfile change here. PI_VERSION is
resolved from the git tag by the workflow (v0.75.5b cache-hit fix), so
no Dockerfile default bump needed.
Workflow change: registry cache-export removed from publish step. buildkit
mode=max cache-export to registry-1.docker.io reproducibly returns HTTP 400
(Hub-CDN protocol mismatch with buildx 0.34.x, surfaced ~2026-05-23).
Diagnosed during opencode-devbox v1.15.12 manual publish: image push works,
only --cache-to fails. Pi-devbox would hit the same regression on the next
tag push without this fix. See opencode-devbox CHANGELOG v1.15.12 for the
full root-cause analysis. Pi-devbox is single-stage with a tiny diff (npm
install pi only) on top of base-latest, so builds are fast even uncached.
ALL FOUR releases v0.74.0 -> v0.75.5 had been shipping the same image
bytes due to a Docker layer-cache hit on the bare 'npm install -g
@earendil-works/pi-coding-agent' command (when PI_VERSION=latest).
The command string is identical across builds, so the layer-hash is
identical, so registry buildcache (cache-from/cache-to) silently
reuses the layer from whatever pi version was current when the cache
was first populated.
Verification: docker manifest inspect joakimp/pi-devbox:vX.Y.Z showed
identical SHA256 digests on both linux/amd64 and linux/arm64 for
v0.74.0, v0.75.3, v0.75.4, v0.75.5. Users on :latest were getting
whatever pi version was baked into the v0.74.0 build.
DISCOVERED 2026-05-23 by user trying to update pi-devbox on MBP-M1
and seeing pi 0.74.0 reported despite pulling v0.75.5.
CHANGES
.gitea/workflows/docker-publish.yml — both smoke and publish jobs
get a new 'Resolve PI_VERSION from tag' step that strips the leading
'v' and any trailing letter suffix from github.ref_name. Result is
passed as a build-arg to docker/build-push-action so the npm install
layer's hash includes the concrete version, forcing cache miss when
pi bumps.
scripts/smoke-test.sh — new run_expect helper that asserts pi
--version contains the EXPECTED_PI_VERSION env var. Smoke job sets
this from the resolve step output. Would have caught this regression
on v0.75.3.
Dockerfile — comment block above ARG PI_VERSION=latest documenting
the cache-hit footgun. The 'if latest' branch in the install RUN is
preserved for local dev convenience but never fires in CI now.
AGENTS.md — new convention bullet explaining the cache-hit class of
bug and noting the latent same-bug in opencode-devbox's with-pi
variants (currently masked by OPENCODE_VERSION bumps; will manifest
when cutting a vN.N.Nb-style opencode-version-unchanged release that
only bumps pi).
CHANGELOG.md — full entry under v0.75.5b describing the recovery,
the silent-failure mechanism, and the verification steps.
NO IMAGE-CONTENT CHANGES vs v0.75.5 INTENT. This build produces the
actual pi 0.75.5 image content that v0.75.5 was supposed to ship.
NEXT FOLLOWUP (parked, not in this commit)
opencode-devbox should get the same workflow change for its
build-variant-with-pi and build-variant-omos-with-pi jobs. Currently
masked because every release also bumps OPENCODE_VERSION which
invalidates the cache, but that masking would fail on a pi-only bump
release.
pi coding-agent container built on opencode-devbox:base-latest.
Includes Dockerfile, docker-compose, CI workflow, smoke-test,
README, CHANGELOG, AGENTS.md.
