Deploy

Application deployment is how you interact with your edge devices. Develop, run and manage your applications

Applications in Synpse can contain one or more Docker containers. These containers can easily talk to each other and utilise all the regular Docker features that you are used to.

CLI

To deploy first application use synpse application create CLI command.

synpse application create hello \
  --image="quay.io/synpse/hello-synpse-go:latest" 

To create or update an application from file use -f flag provide either URL or file location locally

synpse deploy \
  -f https://raw.githubusercontent.com/synpse-hq/hello-synpse-go/main/hello.yaml

​where application spec file is yaml file:

name: hello-synpse
scheduling:
  type: AllDevices
spec:
  containers:
    - name: hello
      image: quay.io/synpse/hello-synpse-go:latest
      ports:
        - 8090:8090

Examples

If you mapping docker run command into Synpse, this part will help you to understand mapping for the arguments

Example 1

Volumes and environment variables

sudo docker run --restart always -d --name homeassistant \
  -v /PATH_TO_YOUR_CONFIG:/config --device=/PATH_TO_YOUR_USB_STICK \
  -e TZ=Australia/Melbourne --net=host \
  ghcr.io/home-assistant/home-assistant:stable

Will translate to:

name: hassio
description: HASS
scheduling:
  type: AllDevices
spec:
  containers:
    - name: homeassistant
      image: ghcr.io/home-assistant/home-assistant:stable
      networkMode: host
      volumes:
        -/PATH_TO_YOUR_CONFIG:/config
        - /etc/localtime:/etc/localtime
      env:
        - name: TZ
          value: Australia/Melbourne
      devices:
        - hostPath: /PATH_TO_YOUR_USB_STICK
          containerPath: /PATH_TO_YOUR_USB_STICK
      restartPolicy:
        name: always

Example 2

A more complex command with arguments:

docker run -d -p 12101:12101 \
  --restart unless-stopped \
  -v "$HOME/.config/rhasspy/profiles:/profiles" \
  --device /dev/snd:/dev/snd \
  synesthesiam/rhasspy-server:latest \
  --user-profiles /profiles \
  --profile en

Will translate to:

name: Rhasspy deployment
description: Rhasspy open source voice assistant application deployment.
scheduling:
  type: AllDevices
spec:
  containers:
    - name: rhass
      image: synesthesiam/rhasspy-server:latest
      args:
        - --profile
        - en
        - --user-profiles
        - /profiles
      devices:
        - hostPath: /dev/snd
          containerPath: /dev/snd
      ports:
        - 12101:12101
      volumes:
        - /data/rhasspy/profiles:/profiles
      restartPolicy:
        name: unless-stopped

Example 3

Exec driver application running firefox in kiosk mode:

name: firefox-kiosk-exec
description: FireFox Kiosk application
scheduling:
  type: AllDevices
  selectors: {}
spec:
  execs:
    - name: exec
      command: firefox
      args:
        - https://synpse.net
      env:
        - name: DISPLAY
          value: :0
      restartPolicy: {}

Example 4

Exec driver with container in one application spec:

name: firefox-kiosk-exec
description: FireFox Kiosk application
scheduling:
  type: AllDevices
  selectors: {}
spec:
  containers:
    - name: hello
      image: quay.io/synpse/hello-synpse-go
      forcePull: true
      restartPolicy: {}
  execs:
    - name: exec
      command: firefox
      args:
        - https://synpse.net
      env:
        - name: DISPLAY
          value: :0
      restartPolicy: {}
