Pack dashboard resources in release package

[fuyufjh]

This will actually break the old-version RW, but it's acceptable to me.

This is because RisingWave's Web resources are served from GitHub repo dashboard-artifact branch, and it's not versioned, i.e. only the latest main build will be kept.

risingwave/docker/Dockerfile.hdfs

Lines 30 to 31 in ae7d7ba

	RUN curl -LO https://github.com/risingwavelabs/risingwave/archive/refs/heads/dashboard-artifact.zip
	RUN unzip dashboard-artifact.zip && mv risingwave-dashboard-artifact /risingwave/ui && rm dashboard-artifact.zip

Hope someday we can ship the frontend resource into / along with the binary.

I think we can take the same approach as the java code, that is, ship the .jars with RisingWave binary together in the tar.gz file

It appears that Dockerfile.hdfs is quite outdated. 😄 We've already switched to build the dashboard artifact in place since #12421.

risingwave/docker/Dockerfile

Lines 15 to 25 in 5a85fe9

	FROM base AS dashboard-builder
	RUN apt-get update && apt-get install -y curl gnupg protobuf-compiler && mkdir -p /etc/apt/keyrings \
	&& curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg \
	&& echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_18.x nodistro main" | tee /etc/apt/sources.list.d/nodesource.list \
	&& apt-get update && apt-get install -y nodejs
	COPY ./dashboard/ /risingwave/dashboard
	COPY ./proto /risingwave/proto
	RUN cd /risingwave/dashboard && npm i && npm run build-static && rm -rf node_modules

Specifically for this case, I would strongly suggest maintaining Dockerfile.hdfs as an extra step in Dockerfile to avoid such inconsistencies.

However, the issue still exist if there's no --dashboard-ui-path specified. We'll proxy to githubusercontent.com then at runtime and it's not versioned. This affect the users who directly download the binary directly or through Homebrew.

risingwave/src/meta/src/dashboard/proxy.rs

Lines 76 to 79 in 5a85fe9

	let url_str = format!(
	"https://raw.githubusercontent.com/risingwavelabs/risingwave/dashboard-artifact{}",
	path
	);

Plan:

• Introduce a new crate dashboard to build the dashboard assets in the build script (build.rs) conditionally based on the configuration, providing a unified entry for serving dashboard assets.

  • Always build and embed in the binary for releases, requiring nodejs toolchain.
  • Do not build but proxy to GitHub for debug/CI builds, unless asked to build.

• The meta crate will depends on dashboard and be no more aware of the source of the dashboard assets. ui-path is deprecated as there's no need of external assets.
