Description

example

webapps-secrets set keyName keyValue [--mode Overwrite|FailIfExists] assigns the value keyValue to the secret keyName and adds the key to the vault. Optionally, you can configure whether to overwrite keyName or abort if the key already exists.

example

example

webapps-secrets set-attributes --secret-key keyName [attrName attrValue] [--scope scopeValue] [--mode Add|Merge|Replace] sets the attributes of the secret keyName. Optionally, you can configure whether to add new attributes to the key, merge the new and existing attributes, or replace all existing attributes with new ones.

example

webapps-secrets get-attributes --secret-key keyName [--scope scopeValue] returns the attributes of the secret with name keyName.

example

webapps-secrets list [--scope scopeValue] lists all currently configured secret keys in the scope scopeValue.

example

webapps-secrets listAll lists all currently configured secret keys in all scopes.

Input Arguments

collapse all

Secret key name to identify the secret, specified as a unique string. If the name contains spaces, keyName must be surrounded by double quotes (").

Wildcards (*) are supported at the end of the secret name. For example, "myapp1.*".

Example: "my password"

Secret key value, specified as a string. The value is encrypted and stored in the MATLAB Web App Server vault. You can retrieve the value from a web app using the getSecret (MATLAB) function.

If the value contains spaces, keyValue must be surrounded by double quotes (").

Example: "AdL3DS2$CyMEgCQQCo9+BpMoYQJxRF+j6ctTi3"

Scope value, specified as any static string or a string with macros. The scope can specify users, groups, or specific web apps to allow access to the designated secret.

The following macros are supported:

  • $UserID—the log on session User ID. To use this macro, you must include userinfo.json in the config/webapps_private directory. For details, see Customize Web App Behavior Based on User.

  • $AppName—the web app name, which includes the CTF file name and folder name.

If a secret has a scope other than the default, you must specify the scope value using the --scope argument when calling set-attributes, get-attributes, list, or remove.

Example: "$AppName.$UserID"

Attribute name, specified as a string. An attribute is unencrypted metadata that is stored along with the secret key name and encrypted value in the webapps_secrets XML file. The attribute name describes the associated attribute value, specified by attrValue.

Example: port

Attribute value, specified as a string. An attribute is unencrypted metadata that is stored along with the secret key name and encrypted value in the webapps_secrets XML file. The attribute value is described by the associated attrName.

Example: 8080
