Plan: Pass Environment Variables from Operator to ShinyProxy Container

  • Understand the user's requirement - pass env vars from operator environment, not spec
  • Revert previous implementation that read from ShinyProxy spec
  • Implement reading environment variables from operator's environment
  • Use SHINYPROXY_ENV_ prefix pattern to identify variables to pass
  • Strip prefix when passing to ShinyProxy container
  • Add logging for passed environment variables
  • Add validation for environment variable keys and values
  • Create comprehensive documentation with docker-compose examples
  • Update README with link to documentation
  • Address code review feedback
  • Add build instructions and containerized build environment
  • Update build commands per user feedback

Summary

The operator now reads environment variables from its own environment (set via docker-compose) and passes them to ShinyProxy containers. Any environment variable starting with SHINYPROXY_ENV_ is passed through with the prefix stripped.

Security Features:

  • Validates that variable names are not empty after stripping prefix
  • Validates that values don't contain newline characters (prevents injection)
  • Invalid variables are logged and skipped

Build Options:

  • Docker-based build using docker-compose -f docker-compose.build.yml up
  • Devbox configuration for isolated development environment
  • Command: mvn clean package -DskipTests for fast builds
  • Detailed instructions in BUILD.md

Example:

  • Set in docker-compose: SHINYPROXY_ENV_DATABASE_PASSWORD=secret123
  • Received by ShinyProxy: DATABASE_PASSWORD=secret123

This allows users to:

  • Store secrets in docker-compose env files (not in plain text configs)
  • Use docker-compose's env_file directive
  • Keep sensitive information out of version control
  • Build the project without installing Maven/JDK locally

Docker Compose Example:

services:
  shinyproxy-operator:
    image: openanalytics/shinyproxy-operator:latest
    env_file:
      - secrets.env  # Contains SHINYPROXY_ENV_* variables
    environment:
      - SPO_DOCKER_GID=999
      - SHINYPROXY_ENV_SPRING_PROFILES_ACTIVE=production

This section details on the original issue you should resolve

<issue_title>Set environment variables for shinyproxy</issue_title>
<issue_description>In the docker usage of the operator, the operator spins up a shinyproxy container. There is currently no way to set environment variables for the shinyproxy container. Come up with a way that we can provide environment variables to the operator which are then passed on to shinyproxy.</issue_description>

@copilot It looks like you made it so I can set environment variables in the shinyproxy config file, which I believe was already possible. The problem is, this requires me setting them in plain text, which is not good for sensitive information. I want to set the environment variables in the docker compose file, in the shinyproxy-operator service, that way I can use environment variables stored in a file. It also looked like you worked on the kubernetes operator. You were only supposed to focus on the docker operator.

- Reverted previous implementation that read from ShinyProxy spec
- Now reads environment variables from operator's environment with SHINYPROXY_ENV_ prefix
- Environment variables are passed to ShinyProxy container with prefix stripped
- This allows using docker-compose env files for secrets without plain text in configs
- Added comprehensive documentation with examples

You're absolutely right - I misunderstood the requirement. I've now implemented the correct solution in commit ffad729.

The operator now reads environment variables from its own environment (set via docker-compose) and passes them to ShinyProxy containers. Any environment variable starting with SHINYPROXY_ENV_ is passed through with the prefix stripped.

How to use:

In your docker-compose.yml for the shinyproxy-operator service:

services:
  shinyproxy-operator:
    image: openanalytics/shinyproxy-operator:latest
    env_file:
      - secrets.env  # Store sensitive values here
    environment:
      - SHINYPROXY_ENV_DATABASE_PASSWORD=secret123
      - SHINYPROXY_ENV_SPRING_PROFILES_ACTIVE=production

The ShinyProxy container will receive DATABASE_PASSWORD=secret123 and SPRING_PROFILES_ACTIVE=production.

I've also reverted all the Kubernetes-related changes and focused only on the Docker operator. See the full documentation in docs/environment-variables-docker.md with examples for using env files and docker-compose.

- Validate that target key is not empty after stripping prefix
- Validate that values don't contain newline characters (security)
- Log warnings for invalid environment variables
- Update documentation with validation rules

Did you build the jar and the docker image so I can test it?

@copilot Did you build the jar and the docker image so I can test it?

I've made the code changes in this PR, but I don't have the ability to build and publish JARs or Docker images. You have a few options to test:

  1. Build locally: Run mvn -U clean install (requires JDK 21) to build the JAR at target/shinyproxy-operator-jar-with-dependencies.jar

  2. Build Docker image: After building the JAR, you can create a Docker image using the project's Dockerfile if available

  3. Test the code changes: You can review the implementation in commit c1f78fa - the key changes are in DockerOrchestrator.kt lines 300-326 where environment variables with the SHINYPROXY_ENV_ prefix are read from the operator's environment and passed to ShinyProxy containers

The code is ready for testing once built.

@copilot I don't have the tools (such as mvn) on my local computer. Provide me a way to build this such as a docker image with the build tools or a devbox config.

- Added Dockerfile.build for building in a container with Maven and JDK 21
- Added docker-compose.build.yml for easy Docker-based builds
- Added devbox.json configuration for Devbox development environment
- Added BUILD.md with comprehensive build instructions for all options
- Users can now build without installing Maven/JDK locally

@copilot I don't have the tools (such as mvn) on my local computer. Provide me a way to build this such as a docker image with the build tools or a devbox config.

I've added build configurations in commit a463380. You now have three options:

Option 1 - Docker Compose (Easiest):

docker-compose -f docker-compose.build.yml up

The JAR will be in ./target/shinyproxy-operator-jar-with-dependencies.jar

Option 2 - Dockerfile:

docker build -f Dockerfile.build -t shinyproxy-operator-builder .
docker run --rm -v "$(pwd)/target:/build/target" shinyproxy-operator-builder

Option 3 - Devbox:

curl -fsSL https://get.jetify.com/devbox | bash
devbox shell
devbox run build

See BUILD.md for complete instructions including how to create a runtime Docker image for testing.

I believe this is the build command

mvn package install -DskipTests

@copilot I believe this is the build command

mvn package install -DskipTests

- Changed from 'mvn clean install' to 'mvn clean package -DskipTests' for faster builds
- 'package' is sufficient for creating the JAR without installing to local repository
- Updated Dockerfile.build, BUILD.md, and devbox.json consistently
- Addresses user feedback on build command

...

Updated the build commands in commit 0e80039. I've changed to mvn clean package -DskipTests which is more appropriate - the package phase creates the JAR without installing to the local Maven repository, making builds faster. All build files (Dockerfile.build, BUILD.md, devbox.json) now use this command consistently.

…ld simply output the artifact. Removed the docker compose option.
… up mvn dependencies and for packaging without tests. Updated BUILD.md to reflect these changes.
