wrk build

wrk CLI tool includes commad build, which provides a way to configure workspaces using workspace.yaml configuration file:

  • Set workspace metadata: name, colors, fonts, icons, links
  • Add workspace UI shortcuts
  • Start applications and services

To use wrk build create workspace.yaml configuration file:

---

# Start applications and services (optional)
start:

    folder: $STATIC_FILESERVER_DIR
    cmd: . env/bin/activate; serve -p 8028 /home/static-server
  - name: Cronicle
    folder: $CRONICLE_DIR
    cmd: rm ./logs/cronicled.pid || true; . env/bin/activate; $CRONICLE_DIR/bin/control.sh setup; $CRONICLE_DIR/bin/control.sh start

In Dockerfile COPY into the image a folder with workspace.yaml together with the assets (images and icons) and run wrk build:

COPY --chown=abc:abc workspace /tmp/workspace
RUN wrk build /tmp/workspace  
RUN rm -rf /tmp/workspace
