# Using Substitution Variable in the Password Field

For the following shared resources, the password is part of the inline credentials, which do not accept substitution variables.

- JDBC
- JMS Connection
- LDAP Connection
- LDAP Authentication
- HTTP Client
- SMTP

For the following shared resources, the password is a keystore password or key alias password. The passwords are stored in resource instance configuration files (runtime) in obfuscated format. These fields accept substitution variables.

- Keystore Provider
- Identity Provider
- Mutual Identity Provider
- SSL Client Provider
- SSL Server Provider

All the password fields have substitution variable validation. If a valid substitution variable in the format `%%svar-name%%` is provided in the password field, which does not accept substitution variable, then the validation error is displayed while saving shared resource in the Application Configurator, while validating configuration, and while generating runtime image.

If the invalid substitution variable is provided (for example, %%pass) in the password field, which does not accept the substitution variable, the validation error is not displayed. Use of characters '%%' is allowed in the password field, provided that the password does not match the valid substitution variable format.

You can use container environment variables as alternatives to substitution variables to update inline credentials. For more information, see "Docker Run Command Reference" topic in TIBCO ActiveMatrix® Service Grid - Container Edition Cloud Deployment.

For example:

    docker run -d -p 8931:8931 -e sr.NewSMTPResource.username=username -e sr.NewSMTPResource.password=obfuscatedPassword --name bookstore bookstore:v1

For more information about creating an obfuscated password from ActiveMatrix Administrator CLI, see "Creating an Obfuscated Password" in TIBCO ActiveMatrix Service Grid Administration Guide.

Also, you can update substitution variable for keystore password or key alias password by using container environment variables.

For example:

    docker run -d -p 10104:10104 -e svar.sr.SVAR1.4_keyAlias=amx  -e svar.sr.SVAR1.4_keyPassword=test123 --name bookstore bookstore:v1

If you are running application in Kubernetes, you can use ConfigMaps to pass substitution variables to the applications. You can also use Kubernetes Secrets to store passwords. For more information, see TIBCO ActiveMatrix® Service Grid - Container Edition Cloud Deployment.
