Add containerised deployment for the Streamlit dashboard - #86
Add containerised deployment for the Streamlit dashboard#86haliliceylan wants to merge 2 commits into
Conversation
Adds the files needed to run dashboard.py on Asimov, alongside the lab's other web projects. Nothing existing is modified. The deployment is driven by kafka-cluster-ansible, which clones the repo as the webuser account and runs ./deploy.sh. That script builds the image and starts the container on the shared bittremieuxlab-public network, where nginx reaches it by service name and serves it at denovobenchmarks.bittremieuxlab.org. Dependencies are pinned in a separate requirements-dashboard.txt rather than the root requirements.txt, which targets the benchmarking pipeline. Streamlit Community Cloud installed streamlit automatically and pulled in pandas as one of its dependencies, so neither was previously listed; a container image gets no such treatment and both must be explicit. The pins mean dashboard dependencies now need deliberate upgrades instead of arriving automatically. results/ is copied into the image at build time, so refreshed benchmark results reach the dashboard by committing them and redeploying. .dockerignore keeps the pipeline out of the build context (sample_data, algorithms, evaluation, tests), reducing it from ~370 MB to ~47 MB.

📝 WalkthroughWalkthroughThe PR adds Docker packaging and Compose deployment for the Streamlit de novo benchmarking dashboard. It defines build-context exclusions, pinned dashboard dependencies, a health-checked container image, and a detached deployment script. ChangesDashboard container deployment
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The containerized deployment currently runs the dashboard as root, does not preserve Streamlit’s CORS/XSRF protections, and can report deployment success without enforcing build or health-check success; these create concrete security and availability risks, so the PR is not ready to merge until the runtime defaults and deployment checks are corrected.

Pull request overview
This PR adds a containerized deployment setup for the existing Streamlit dashboard (dashboard.py) so it can be built and run via Docker Compose on the lab’s shared network and served behind nginx.
Changes:
- Add a dedicated pinned dependency set for the dashboard (
requirements-dashboard.txt). - Add a
Dockerfilethat builds apython:3.12-slimimage runningstreamlit run dashboard.py. - Add deployment automation and configuration (
docker-compose.deployment.yaml,deploy.sh,.dockerignore) to build/run the service on the shared network.

These two overrides were carried over from the gnps-rdd deployment, which in turn appears to follow .devcontainer/devcontainer.json. Neither is needed here: verified behind nginx with both protections at their secure defaults, the dashboard renders and its websocket works normally. Removing them avoids disabling protections without a reason to. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Docker Compose up --wait --wait-timeout version introduced support
💡 Result:
The --wait-timeout option for the docker compose up command was introduced in Docker Compose v2.17.0 [1]. This feature was implemented via pull request #10276 [2][3], which addressed the need to prevent the up --wait command from waiting indefinitely for services to reach a "running" or "healthy" state [2]. It is worth noting that during the initial implementation in v2.17.0, there was a temporary regression where the existing --timeout flag (used for container shutdown) was accidentally renamed to --wait-timeout [1]. This issue was corrected in a subsequent release (v2.17.2) [1].

Run Streamlit as a non-root user.
The image has no USER instruction before ENTRYPOINT, so Streamlit runs as root. A compromise in the dashboard process would then grant root privileges inside the container.
Create a dedicated unprivileged user, assign the required /app ownership, and set USER before ENTRYPOINT.
