Exiting a Cloud Workstation Session
There are two mechanisms to exit a Cloud Workstation session - Hold and Shutdown.
Hold and Shut Down sync new content created in the Cloud Workstation back to the capsule. The main difference between Hold and Shut Down:
Hold Keeps all the packages installed and the folder you created in the session. When you return to the session, you can continue working without having to reinstall or recreate them.
Shut Down Reminds you of the installed packages, if you want them in your Cloud Workstation, you need to add them to the capsule environment and rebuild the capsule first.
Hold and Continue a Cloud Workstation
When exiting a Cloud Workstation via Hold, the system will suspend the docker container from the capsule. This will preserve all working spaces at the time when you leave the Cloud Workstation. The next time you access the capsule, it will resume the Cloud Workstation session with all the command history, the files, or folders you created, and the packages you installed in the previous session.
For reproducible purposes, it is strongly recommended to install packages using the Environment Editor.
To Exit a Cloud Workstation with Hold
Click the Shut Down button.
Click Hold to return to the capsule and close the Cloud Workstation.
After the Cloud Workstation is held, the system redirects you to the capsule view.
On the capsule dashboard, you can see the status of the capsule is 'CW on hold' when you hover over the capsule.
Edit a 'CW on Hold' Capsule
You can edit a capsule with a 'CW on Hold' status. The capsule view is the same as the other capsule. You can add new files, execute a reproducible run, attach secret and dataset.
You can add packages in the environment editor, but since the cloud workstation is on hold (the docker container for the computation is on hold), the changes will be effective when the docker container is rebuilt.
Resume/Discard a 'CW on Hold' Capsule
In the capsule view under the reproducible run button, you can select Resume or Discard a CW held capsule.
Resume will redirect you to a Cloud Workstation and continue your last session.
Discard will shut the Cloud Workstation down.
Collaborating on a Held Capsule
Collaborators can see the capsule with files synced from a held Cloud Workstation session. If they have edit permissions, they can resume the stopped Cloud Workstation to continue working from the previous session.
To resume the Cloud Workstation, click Resume.
Shut Down a Cloud Workstation
When exiting a Cloud Workstation from Shut Down, the system turns off the docker container associated with the capsule and syncs back all the content under the "capsule" folder. This means that it will not preserve any content created outside the "capsule" folder, or any packages installed during the session. Installed packages will be suggested via a reminder in Package Suggestions, you can choose to add them to the environment editor.
Folders or files saved outside of the data or results folder are not synced back to the compute capsule and are lost in a new Cloud Workstation session or in the compute capsule.
Package Suggestions
The system detects new packages that were installed during your Cloud Workstation session. When you shut down the Cloud Workstation and return to the capsule view, a reminder will appear indicating the new packages that were installed in the Cloud Workstation.
After exiting the Cloud Workstation, the packages installed during the Cloud Workstation session must be reviewed and added to the environment of the capsule. If you want to reproduce the environment that you created in the Cloud Workstation, go through the package suggestions and add the package to the environment editor. Refer to Packages and Package Managers to learn more about installing packages in the capsule view.
