From bf357015bcd87fc99b955bbf531a9521bb19e87f Mon Sep 17 00:00:00 2001 From: Cyrille Nofficial Date: Sat, 5 Sep 2026 11:09:28 +0200 Subject: [PATCH] build: fix Docker build and switch releases to the homelab Tekton pipeline The Dockerfile was broken since the MCP endpoint was added: it built a single file (cmd/domogeek/domogeek.go) instead of the whole package, so mcp.go's symbols (calendarDayFor, newMCPHandler) were undefined. Fixes that by building ./cmd/domogeek, pins the builder image to golang:1.27-alpine (module now requires go 1.25+), and drops the hardcoded GOOS/GOARCH=amd64 so multi-arch builds compile natively per platform instead of always producing an amd64 binary. Also fixes .Dockerignore (wrong case, never actually read by docker/buildah) by renaming it to .dockerignore, and anchors its "domogeek" pattern to /domogeek so it excludes only the compiled binary, not the whole cmd/domogeek source directory (same bug as the .gitignore fix in an earlier commit). Removes build-docker.sh: image releases now go through the existing homelab Tekton pipeline (gitea-docker-build-multiarch), triggered by a Gitea webhook on tag push, same pattern as other repos (e.g. dra-devices). Images move from docker.io/cyrilix/domogeek to git.cyrilix.bzh/cyrilix/domogeek. Documented in CLAUDE.md and README.md.

Note: despite the "caldav flags are optional" framing, `main()` currently calls `calendar.NewCaldav` unconditionally, even with an empty `-caldav-url` — with no caldav server to validate against, this hits the 1000-retry exponential backoff described below and the process never gets to `http.ListenAndServe`. This is a pre-existing quirk, not something introduced by the MCP work; if you need a quick local instance (e.g. to exercise `/mcp` or `/calendar` without a real CalDAV server), it's easiest to call `newMCPHandler()`/`calendar.New(location)` directly from a small throwaway `main`/test rather than running the built binary. -Docker image (multi-stage, distroless): +Docker image (multi-stage, distroless), for local testing: ```bash -docker build -t domogeek . +docker build -t domogeek . # or: buildah bud -t domogeek . ``` -`build-docker.sh` is the multi-arch (amd64/arm64/arm/v7) release build using `buildah`, producing a manifest pushed to `docker.io/cyrilix/domogeek:`.
