deepseek-kubernetes-sandbox/README.md

Here is the complete updated Dockerfile incorporating the hoisted deploy fix and the dependency patch. The key changes versus the last version are in the deploy block: --legacy is dropped, node-linker=hoisted and inject-workspace-packages are enabled, and the missing workspace peer is added via the workspace:* protocol.

What changed and why

Area	Before	Now	Reason
Deploy linker	default isolated .pnpm store	--config.node-linker=hoisted	Produces a flat npm-style tree so peer deps like @deepseek-ai/cosmokit are physically present.
Deploy flag	--legacy	removed	Legacy deployer does not reliably bind peer dependencies; the modern deployer does.
Workspace binding	implicit	--config.inject-workspace-packages=true	Guarantees workspace packages and their peers are bound into the closure deterministically.
Missing peer patch	@deepseek-ai/cordis-plugin-group@^1.0.1	@deepseek-ai/cordis-plugin-group@workspace:*	Correct protocol for a monorepo-internal package; no dependency on a published npm version.
Verification	only bin.js exists + web --help	also asserts cosmokit and cordis-plugin-group directories exist	Fails the build early if the closure is still incomplete, instead of failing at container start.

Build and run

docker build \
  --build-arg DSH_VERSION=dsh-v0.2.1-rc.2 \
  -t dsh-web:0.2.1-rc.2 .

docker run --rm -it \
  -p 3080:3080 \
  -v dsh-home:/home/node/.dsh \
  -e DEEPSEEK_API_KEY \
  dsh-web:0.2.1-rc.2

Then open the dsh web: URL printed in the logs (it carries a per-process access token).

If the pnpm add …@workspace:* step ever fails

That would mean @deepseek-ai/cordis-plugin-group is not a workspace package in the chosen tag. In that case remove the two pnpm --filter … add lines; the hoisted linker alone is usually sufficient to include peer dependencies. You can confirm by checking that the test -d /opt/dsh/node_modules/@deepseek-ai/cordis-plugin-group assertion still passes.
