Update Dockerfile #6550
Conversation
WalkthroughThe Dockerfile was refactored to streamline the multi-stage build process, clarify dependency installation, and enhance runtime security by using a non-root user. Proxychains configuration was updated to generate its config file in a temporary directory, and environment variable management was improved for both build and runtime stages. Changes

11-13: Avoid hard-coding Yarn registry; make it configurablePinning the registry to
registry.npmmirror.comcan break CI/CD when the mirror is unavailable or slow and may raise supply-chain concerns. Prefer reading the registry from an ARG/ENV (falling back to npmjs) so image consumers can override it.- RUN yarn config set registry 'https://registry.npmmirror.com/' && \ - yarn install --frozen-lockfile +ARG YARN_REGISTRY=https://registry.npmjs.org/ +RUN yarn config set registry "${YARN_REGISTRY}" && \ + yarn install --frozen-lockfile
17-17:apk updatebloats the layer
apk add --no-cachealready refreshes indexes; the explicitapk updatecreates an extra layer and cannot be cleaned up, increasing image size.-RUN apk update && apk add --no-cache git +RUN apk add --no-cache git
71-76: Proxy URL parsing is brittle
cut-based splitting fails for URLs containing credentials (http://user:pass@host:8080) or IPv6 hosts. Consider using a small shell utility (e.g.,busybox wgetβsurlparser, orawk) or expect users to provide protocol/host/port separately.No change required if current format is guaranteed, but please double-check.

68-69: Overwriting the reservedHOSTNAMEvariable is risky
HOSTNAMEis automatically set by Docker to the container ID. Replacing it with"0.0.0.0"can confuse tooling that relies on the standard meaning (e.g., debuggers, logs). Use a custom variable such asAPP_HOST.-ENV HOSTNAME "0.0.0.0" +ENV APP_HOST "0.0.0.0"

π οΈ Refactor suggestion
Mixed ownership: /app/public remains root-owned
The .next artifacts are correctly --chowned, but public/ is copied without ownership override. Running as the nextjs user may fail if the app needs to write (e.g. logs, uploads) inside public.
-COPY --from=builder /app/public ./public
+COPY --from=builder --chown=nextjs:nodejs /app/public ./publicπ€ Prompt for AI Agents
In Dockerfile lines 54 to 56, the COPY command for /app/public does not specify
ownership, leaving it root-owned, while the .next artifacts are copied with
--chown=nextjs:nodejs. To fix this, add --chown=nextjs:nodejs to the COPY
command for /app/public to ensure consistent ownership and prevent permission
issues when the app runs as the nextjs user.

chmod 777 opens a security hole
World-writable permissions on /app/app/mcp allow any process (including a breakout) full control. Limit access to the application user.
-RUN mkdir -p /app/app/mcp && \
- chmod 777 /app/app/mcp
+RUN install -d -o nextjs -g nodejs -m 775 /app/app/mcpπ€ Prompt for AI Agents
In Dockerfile lines 59 to 60, the directory /app/app/mcp is given world-writable
permissions with chmod 777, which is a security risk. Change the permissions to
restrict access only to the application user by setting more restrictive
permissions such as 755 or 700, depending on the needed access, and ensure the
directory ownership is assigned to the application user instead of allowing all
users full control.
