This is optional but now enabled for release builds.
Why?
* It shrinks the release docker images a bit, as the binary
includes only the gzipped version of files and uncompressed into RAM
at startup (which should be fast).
* It's a step toward #160.
* support cross-compiling an x86-64 target on an arm64 host. This
it turns out is a matter of *removing* an unnecessary dependency.
(aarch64-linux-gnu-pkg-config exists but x86_64-linux-gnu-pkg-config
doesn't. Turns out neither is necessary.) Added a comment explaining
where ${gcc_target}-pkg-config comes from now.
* documentation tweaks
* improve debug output a bit
I'm tired of all the boilerplate, so use the new
GPL-3.0-linking-exception license identifier instead in all the server
components.
I left the ui stuff alone because I'm just going to replace it (#111).
Add a checker for the header because it's easy to forget.
This eases build setup. Where Yarn requires a separate package
repository, npm is available in the standard one.
yarn's package repository signature was recently expired, and apparently
will expire again in a year. Avoid dealing with that.
Fixes#110.
Besides being more clear about what belongs to which, this helps with
docker caching. The server and ui parts are only rebuilt when their
respective subdirectories change.
Extend this a bit further by making the webpack build not depend on
the target architecture. And adding cache dirs so parts of the server
and ui build process can be reused when layer-wide caching fails.
This replaces the previous Dockerfile, which was a single stage for
building and deployment.
The new one is a multi-stage build. Its "dev" target has the full
development environment; its "deploy" target is more slim. It supports
cross-compiled builds via BuildKit, eg to prepare a build suitable for
a Raspberry Pi:
docker buildx build --load --platform=linux/arm64/v8 --tag=moonfire-nvr --progress=plain --target=deploy -f docker/Dockerfile .
Coming next: updating the installation docs.
