# Docker-Tray
|
||||
|
||||
Docker-Tray is a C++ application to monitor docker.service and allows to start and stop the service from system tray.
|
||||
|
||||
## Execution
|
||||
|
||||
Running the application.
|
||||
|
||||
```bash
|
||||
g++ docker-service-tray.cc -o docker-tray `pkg-config --cflags --libs gtk+-3.0 appindicator3-0.1` -lsystemd
|
||||
./docker-tray
|
||||
```
|
||||
|
||||
## Dependencies
|
||||
```
|
||||
gtk+-3.0
|
||||
appindicator3-0.1
|
||||
lsystemd
|
||||
```
|
||||
The application utalizes sd_bus for hooking service states.
|
||||
|
||||
|
||||
## Contributing
|
||||
Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
|
||||
|
||||
To do:
|
||||
* Implement make, build and packing
|
||||
* Enable/Disable service from tray.
|
||||
* Enable/disable application on startup
|
||||
* Refactor the code, implement proper testing.
|
||||
|
||||
Please make sure to update tests as appropriate.
