Context

mse uses various directories to save information about the deployed applications.

The user login information is stored in: $HOME/.config/mse/login.toml on Linux/MacOS and %APPDATA%\mse\login.toml on Windows.

Workspace¶

Any files created during the deployment process are stored in /tmp/uniqueName/ such as:

The encrypted files
The code tarball
The certificates
and so on.

Context¶

mse also creates a directory $HOME/.config/mse/context/{uuid}/ when a deployment is successfully completed.

This directory contains:

The tarball of the encrypted code
A TOML file which contains the details required for a user to verify the trustworthiness of the app

This directory is designed to be shared with any app users wishing to verify the trustworthiness of the app.

List¶

You can list the contexts saved on your local host using:

$ mse cloud context --list
852a4256-fffa-457a-80ed-329166a652af -> helloworld-1.0.0 (2022-11-23 16:22:34.621387)
[...]

Remove¶

You can remove the context directory of an app using:

$ mse cloud context --remove 852a4256-fffa-457a-80ed-329166a652af
[...]

Warning

If you do that, you will lose the configuration and the tar code. That will make you unable to share these information, thus an app user will be unable to verify the trustworthiness of your app

Purge¶

You can also remove all your context directories:

$ mse cloud context --purge
[...]

Warning

If you do that, you will lose the configuration and the tar code for all apps. That will make you unable to share these information, thus an app user will be unable to verify the trustworthiness of all of your apps

Export¶

If you want app users to verify the trustworthiness of your apps, they will need this context file from the context directory which can be exported using:

$ mse cloud context --export 852a4256-fffa-457a-80ed-329166a652af
Exporting 852a4256-fffa-457a-80ed-329166a652af context in context.mse...
You can now transfer this file to your app user.

You can now share this file with the users.
