Nuvolos has a new feature for enhancing user productivity and collaboration - application exports. We believe that Nuvolos is the best place for collaborating on research projects and academic materials, yet in certain cases it is not practical to do everything on Nuvolos. For example,
students experimenting with code of an old course
researchers sharing supporting applications for their papers
industry experts running applications on multiple infrastructures
can benefit from Nuvolos applications exported to Docker images.
What does this mean? Users can now export eligible applications to public images hosted on . These can be reused on any infrastructure with the ability to run Docker containers, from desktop computers to compute clusters.
For eligible apps, you'll see a new Export application entry for the actions dropdown.
Clicking on this item will bring up a dialog to pick a name for your docker image (note that you can only choose the last part of the image tag - the rest is generated by the system automatically to avoid collisions). Also, you can control if the Workspace files should be part of the docker image or not.
It is important to understand that your application will be exported to a public docker image hosted on DockerHub. Anyone in the world will be able to use your image without any form of authentication. For this reason, it is of paramount importance to avoid storing sensitive data in your application's library area, as it will be part of the generated image.
The exported image of a Nuvolos application will contain the following data:
A default startup command to launch the app's executable
The image may also contain the Workspace files, unless you explicitly opt out when creating the image.
The exported image will not contain:
You can review all exported applications in a given instance by clicking on the exports button next to the Add new application button on the applications screen:
In the exported environments screen, you can review all your exported images and delete them if you don't want them to be accessible anymore.
Nuvolos exports applications to standard docker images. On machines with a docker runtime and internet access, you can use the start command provided in the actions column on the exports screen:
The command will look like this:
If the image is not yet present locally, the above command will automatically pull it from DockerHub and run it. You can access your application by connecting to port 8888 on your machine:
You might want to back up or archive your images somewhere else other than DockerHub. We recommend pulling the image using docker then save it as an archive:
The archived image can be loaded back using the load command:
Your application configuration, including installed packages/extension stored in the area.
