Oryx

Oryx is a build system which automatically compiles source code repos into runnable artifacts. It is used to build web apps for Azure App Service and other platforms.

To receive updates on runtimes and versions supported by Oryx and App Service, subscribe to Azure Updates or watch the github.com/Azure/app-service-announcements tracker.

Oryx generates and runs an opinionated build script within a build container based on analysis of a codebase's contents. For example, if package.json is discovered in the repo Oryx includes npm run build in the build script; or if requirements.txt is found it includes pip install -r requirements.txt.

Oryx also generates a run-time startup script for the app including typical start commands like npm run start for Node.js or a WSGI module and server for Python.

The built artifacts and start script are loaded into a minimalistic run container and run.

Supported platforms and versions

Link

Patches (0.0.x) are applied as soon as possible after they are released upstream.

Get started

Though built first for use within Azure services, you can also use the Oryx build system yourself for troubleshooting and tests. Following are simple instructions; for complete background see our architecture doc.

Oryx includes two command-line applications; the first is included in the build image and generates a build script by analyzing a codebase. The second is included in run images and generates a startup script. Both are aliased and accessible as oryx in their respective images.

oryx build

When oryx build is run, the system detects which programming platforms appear to be in use and applies toolsets appropriate for each one. You can override the default choices through configuration.

The --output (or -o) parameter specifies where prepared artifacts will be placed; if not specified the source directory is used for output as well.

For all options, specify oryx --help.

oryx create-script -appPath

When oryx is run in the runtime images it generates a start script named run.sh, by default in the same folder as the compiled artifact.

Support for Build Configuration File

The App Service YAML file (appsvc.yaml) is used to specify the build and run commands for your Web Apps, thus overriding any defaults provided by the App Service Build Service. App Service expects this file to be in the root directory of your project.

Format

There are ordered keys for pre-build, post-build, and run. The commands/scripts referenced by these keys are executed in-order. If a key is missing, it will be skipped and the next key will be processed. An optional version key specifies the version of the appsvc.yaml file, if new versions are introduced in the future.

version: 1

pre-build: apt-get install jq

post-build: |
    python manage.py makemigrations
    python manage.py migrate

run: gunicorn myapp.app --workers 5

Build and run an app

To build and run an app from a repo, follow these approximate steps. An example script follows.

1. Mount the repo as a volume in Oryx's docker.io/oryxprod/build container.
2. Run oryx build ... within the repo directory to build a runnable artifact.
3. Mount the output directory from build in an appropriate Oryx "run" container, such as docker.io/oryxprod/node-10.14.
4. Run oryx ... within the "run" container to write a startup script.
5. Run the generated startup script, by default /run.sh.

# Run these from the root of the repo.
# build
docker run --volume $(pwd):/repo \
    'mcr.microsoft.com/oryx/build:latest' \
    oryx build /repo --output /repo

# run

# the -p/--publish and -e/--env flags specify and open a host port
docker run --detach --rm \
    --volume $(pwd):/app \
    --env PORT=8080 \
    --publish 8080:8080 \
    'mcr.microsoft.com/oryx/node:10' \
    sh -c 'oryx create-script -appPath /app && /run.sh'

Build Server Invocation

1. Build the Oryx solution
   1. 
2. Create image with oryx and platform binaries
   1. time build/buildBuildImages.sh -t ltsversion
3. Run docker to port map, volume mount a directory, specify the image with oryx build, and invoke BuildServer

   1.  docker run -it -p 8086:80 \
       -v C:\Repo\Oryx\tests\SampleApps\:/tmp/SampleApps \
       -e "ASPNETCORE_URLS=http://+80" \
       oryxdevmcr.azurecr.io/public/oryx/build:lts-versions \
       /opt/buildscriptgen/BuildServer

      
4. Invoke build
   1. 
      1. Under the hood oryx build is invoked

         oryx build [sourcePath] \
             --platform [platform] \
             --platform-version [version] \
             --output [outputPath] \
             --log-file [logPath]

5. Check build status with id 1
   1. 
6. Check server healthcheck
   1. 

Components

Oryx consists of a build image, a collection of runtime images, a build script generator, and a collection of startup script generators. For more details, refer to our architecture page.

Testing Locally

startup script generator

build/testStartupScriptGenerators.sh will perform tests on all startup script generators written in go. The tests are copied into a docker image for performing go test on all platforms.
