This also improves the memory efficiency of the sync mechanism by
calculating the stage ids on the fly instead of storing the full
build output in memory and then parsing the string.
Restructure the supervisor image to remove the dependency on the custom `alpine-supervisor-base`
image and the custom node build. The dockerfile is now a multi-stage
build that splits the process into two build stages and two runtime
stages.
Here is the full list of changes
- The node binary is now copied from `balenalib/${ARCH}-alpine-node:12-run`, the node binary
now supports running with a debugger.
- The runtime image now inherits from the official `alpine:3.16` image
- Tests are ran within the runtime image configuration instead of the
build image
- Livepush is ran within the runtime image context
- Unnecessary packages have been removed
- Removed avahi-daemon.conf as that service is not being used
- Fix livepush to work with a multi-stage image. This also deprecates the `image-tag` argument to npm run sync as
`SUPERVISOR_TAG` is no longer used by new OSs
- Fix livepush build on old rpi devices. Allows passing a 'PREFIX'
argument to let the builder pull images directly from docker hub arch
repositories. Relates to https://github.com/balena-os/balena-engine/issues/269
Change-type: patch
The `start-resin-supervisor` script in newer OS version no longer uses the
SUPERVISOR_TAG environment variable setup on supervisor.conf and
update-supervisor.conf.
This change removes the need for that variable with livepush supervisor
to make it compatible with older and newer OS versions
Change-type: patch
We move the old sync.js script to tools/, and delete the now-broken
sync-debug.js.
We add a command `npm run sync`, which starts a livepush process
with the supervisor on a device.
Change-type: minor
