It automatically generates Docker containers for some SIFIS-Home third-party applications through Continuous Integration using code as starting point.
To extract the labels from the Docker image, the get-labels.sh script has been
created. This script retrieves Docker image labels without pulling an
image from the ghcr hub.
To get labels for the lamp image on amd64:
./get-labels.sh gchr.io/sifis-home/lamp-amd64 latest
The second option, latest, represents the most recent version of the image.
To get labels for the lamp image on arm64:
./get-labels.sh gchr.io/sifis-home/lamp-arm64 latest
Both the two labels are printed on shell.
A less efficient solution to retrieve the labels is to run the docker inspect
command. This solution implies that the image has already been pulled image.
To extract the labels from the pulled image, run the following command:
docker inspect --format='{{json .Config.Labels}}' ghcr.io/sifis-home/lamp-amd64
This label is a percentage that represents the quality of a software. Within the marketplace, this label is visualized with a colored cicle, following a traffic light scheme.
Below an example using the 100% value.
Software quality
[Red icon]
[Orange icon]
[Green icon turned on] 100%
The title Software quality must be bold.
The term turned on means that the color associated to the percentage
must be more saturated compared to the others.
Below the list of rules to associate the percentage with the right color:
- Red --> when percentage < 60%
- Orange --> when 60% <= percentage < 80%
- Green --> when percentage >= 80%
The second label, called manifest, contains a json with the
hazards associated to each SIFIS-Home API used in the application.
In the marketplace, it must be possible to visualize this json file and
download it.
