Builds LavinMQ from the upstream source release for x86_64 and packages the OpenRC service plus /etc/lavinmq defaults. The locked Shards dependencies and frontend assets are versioned, checksummed source inputs, so the build does not need network access.

Build command:

make

LavinMQ 2.10.1 requires Crystal 1.21.0 or newer. The package uses Alpine edge's native Crystal package, avoiding a glibc toolchain in the Alpine musl build.

Runtime Layout

Installs:

lavinmq
lavinmqctl
lavinmqperf
/etc/lavinmq/lavinmq.ini
/var/lib/lavinmq

Default ports:

5672: AMQP
15672: management UI

OpenRC Usage

apk add lavinmq lavinmq-doc lavinmq-openrc
rc-update add lavinmq default
rc-service lavinmq start

Install daily rotation for the OpenRC service log, retaining 14 compressed archives:

apk add lavinmq-logrotate

Wrapper settings in /etc/conf.d/lavinmq:

LAVINMQ_CONFIG: config file path passed with --config
LAVINMQ_DATA_DIR: data directory passed with -D
LAVINMQ_OPTS: extra LavinMQ arguments appended after package defaults

Updating LavinMQ

In APKBUILD, set pkgver to the new upstream version and reset pkgrel to 0.
Add versioned vendored archives for the locked Shards dependencies and frontend assets. If the new upstream shard.lock and the asset rules in its Makefile are unchanged, the existing archives can be reused under the new names:
```
cd packaging/alpine/local/lavinmq
cp lavinmq-2.10.1-shards.tar.gz lavinmq-<version>-shards.tar.gz
cp lavinmq-2.10.1-assets.tar.gz lavinmq-<version>-assets.tar.gz
git add -f lavinmq-<version>-shards.tar.gz lavinmq-<version>-assets.tar.gz
```
When shard.lock changes, extract the upstream source, run shards install --production in it, and create the shards archive with tar -czf lavinmq-<version>-shards.tar.gz lib. If the asset rules change, download the files specified by the new Makefile to a staging directory and create lavinmq-<version>-assets.tar.gz from that directory's contents.

From the repository root, refresh checksums and build the package:

ALPINE_PACKAGE=lavinmq mise run apk:checksum
ALPINE_PACKAGE=lavinmq mise run apk:build
