Streamlining Development: Integrating Vega SDK into Continuous Integration Pipelines

Vega Open Beta Knowledge Base
1

Automating your build and deployment processes is crucial for maintaining consistent, high-quality software releases. For teams working with the Vega SDK, integrating it into your Continuous Integration (CI) pipeline can significantly streamline your development workflow. This guide will walk you through the process, best practices, and common pitfalls to avoid.

1. Understanding Vega SDK Installation in CI Environments

The Vega SDK installation process needs special consideration when implementing it in a CI environment. Unlike developer workstations where interactive installation is common, CI environments require a fully automated approach.

Build Host Requirements

Your build host (whether virtual or physical) needs to meet the system requirements documented on the installation page:

  • Compatible operating system (e.g., Ubuntu 20.04, 22.04, and 24.04 for Linux builds, Mac OS X)
  • Appropriate architecture support (e.g., arm64 or x86_64 for Mac, x86_64 for Linux)
  • Sufficient storage space for SDK installation

On the installation page, ensure that you select the corresponding platform for your CI build host and not for your development machine.

React Native Considerations

If you’re building a React Native application, you’ll need to configure your npm client to use Amazon’s private npm registry (required during this phase under disclosure). This ensures access to Vega-specific npm packages during the build process.

2. Key Behaviors and Important Changes

Non-root User Requirement

A significant change came with version 0.20.3106:

  • Prior SDK versions required a non-root user for installation
  • Version 0.20.3106 and later removed this requirement for non-interactive installations
  • Set NONINTERACTIVE=true for CI environments

Optional KVD Image Installation

To optimize your CI environment and critically reduce storage used:

  • Starting from version 0.20.3106, the Vega Virtual Device (KVD) image installation is optional
  • Remove the --sim-url flag to skip KVD installation
  • This significantly reduces the installation footprint

VS Code Plugin Considerations

Don’t be alarmed by VS Code plugin installation warnings in your CI environment. These are expected and can be safely ignored as they don’t affect the SDK’s functionality in CI/CD pipelines.

3. Installation Control Through Environment Variables

The Vega SDK installer provides extensive customization through environment variables. Here are the most crucial ones for CI environments:

# Essential CI/CD Variables
NONINTERACTIVE=true        # Required for CI/CD scenarios
DELETE_DOWNLOADS=false     # Useful for repeated installations
INSTALL_ROOT_DIR=/custom/path  # Custom installation directory
OVERWRITE_PREVIOUS=true    # Automatically overwrite existing installations

Additional variables will be documented in the future as part of our documentation portal

4. Practical Implementation

Here’s an example Dockerfile that demonstrates how to integrate Vega SDK into your build environment:

FROM ubuntu:22.04

SHELL ["/bin/bash", "-c"]

# Need cURL to fetch the installer.
RUN apt-get update && \
    apt-get install curl ca-certificates --no-install-recommends -y && \
    rm -rf /var/lib/apt/lists/*

# Install Vega SDK
ARG INSTALLER_SCRIPT
ARG SDK_VERSION
ARG SDK_URL
ARG SDK_ROOT=/kepler
ARG SIM_URL # omit to skip KVD install
RUN test -n "$INSTALLER_SCRIPT" || (echo "INSTALLER_SCRIPT not set" && false)
RUN test -n "$SDK_VERSION" || (echo "SDK_VERSION not set" && false)
RUN test -n "$SDK_URL" || (echo "SDK_URL not set" && false)
RUN curl ${INSTALLER_SCRIPT} | NONINTERACTIVE=true INSTALL_ROOT_DIR=${SDK_ROOT} bash -s -- \
    --sdk-url=${SDK_URL} \
    --sim-url=${SIM_URL} \ # remove to skip KVD install
    --version=${SDK_VERSION}

## Setup required environment variables
## Note that the script installs into $SDK_ROOT/sdk/$SDK_VERSION
## If $SDK_ROOT was not set, it defaults to /kepler
ENV KEPLER_SDK_PATH="$SDK_ROOT/$SDK_VERSION"
ENV PATH="$KEPLER_SDK_PATH/bin:$PATH"

## Verify kepler command is available
RUN kepler -v

# If you are building a React Native app, NodeJS and npm are required
RUN curl -sL https://deb.nodesource.com/setup_lts.x | bash -
RUN apt-get update && apt-get install -y nodejs
RUN npm install -g npm

## Set global npm config path to /etc/npmrc
## Bind mount your npmrc config to this location
ENV NPM_CONFIG_GLOBALCONFIG="/etc/npmrc"
## Verify node and npm commands are available
RUN node -v && npm -v

ENTRYPOINT [ "/bin/bash", "-c" ]

You would build that docker image like this:

docker build . --tag ksdk \
   --build-arg INSTALLER_SCRIPT={take string from developer portal}
   --build-arg SDK_URL={take string from developer portal} \
   --build-arg SDK_VERSION={take string from developer portal}

Find the strings you need to replace here: SDK installation, point 4.. Before copying the values, ensure that you select the corresponding platform for your CI build host and not for your development machine. If you select the incorrect platform, you may encounter installation or runtime errors.

5. Best Practices

  1. Version Control
  • Always specify exact SDK versions in your CI configuration
  • Consider version pinning for stability
  • Document version updates in your repository
  1. Performance Optimization
  • Skip KVD installation when not needed
  • Use caching strategies for downloaded artifacts
  • Consider using multi-stage builds
  1. Security Considerations
  • Use secure download URLs (HTTPS)
  • Implement proper access controls for private registries
  • Regular security audits of CI/CD pipelines

6. Common Issues and Solutions

  1. Installation Failures
  • Verify network connectivity to SDK repositories
  • Ensure sufficient disk space
  • Check environment variable configuration
  • Ensure correct platform for build host was selected
  1. Build Errors
  • Verify SDK version compatibility
  • Check for missing dependencies
  • Review build logs for specific error messages
  • Ensure correct platform for build host was selected during installation

7. Conclusion

Integrating Vega SDK into your CI pipeline might seem daunting at first, but with proper planning and implementation, it can significantly improve your development workflow. Focus on automation, performance, and security while following the best practices outlined above.

To get started:

  1. Evaluate your current CI environment
  2. Plan your integration strategy
  3. Implement the necessary changes
  4. Monitor and optimize the process

Remember to keep your SDK versions updated and regularly review your CI configuration for potential improvements.
