How to use the command 'pulumi logout' (with examples)

The pulumi logout command is an essential tool for users of the Pulumi infrastructure as code platform. It allows users to log out of their current Pulumi sessions. This ensures that Secure Sockets Layer (SSL) and authentication tokens related to the Pulumi cloud or other backends are effectively disabled, maintaining security and privacy. Logging out after your session can prevent unauthorized access to your infrastructure resources, especially in shared environments.

Use case 1: Log out of a specific cloud backend

Code:

pulumi logout url

Motivation: In some scenarios, developers or DevOps engineers might be utilizing multiple backends for managing infrastructures, such as AWS, Azure, or GCP with their respective Pulumi projects. Using pulumi logout url, users can precisely target and log out from a specific backend. This feature is crucial when dealing with multiple accounts as it allows you to log out of a particular session without disturbing connections to other essential environments or services.

Explanation:

• url: This argument specifies the exact backend (e.g., a specific cloud provider’s endpoint) from which you want to log out. This ensures that your action affects only the intended targeted environment.

Example Output:

Logged out successfully from https://app.pulumi.com/account_name

Use case 2: Log out of all backends simultaneously

Code:

pulumi logout --all

Motivation: Security practices often necessitate clearing all session tokens and credentials from a device, particularly when a developer finishes working across multiple environments. By using pulumi logout --all, users can efficiently log out from all backends at once. This prevents credentials from unintentionally lingering, reducing the risks associated with cached authentication tokens across various projects.

Explanation:

• --all: This flag instructs Pulumi to terminate all active sessions across every registered backend. It’s a sweeping command for comprehensive security coverage, especially useful in environments where there is frequent context-switching between different cloud accounts.

Example Output:

Logged out successfully from all cloud backends.

Use case 3: Log out using local mode

Code:

pulumi logout --local

Motivation: When working in local mode, users might have configurations or sessions stored locally, without leveraging any remote server or cloud service backend. pulumi logout --local is a specialized command for terminating those local sessions effectively, essential for scenarios where security policies mandate clearing up local authentication-related data after usage.

Explanation:

• --local: The use of this flag specifies that the logout operation should apply to configurations stored locally. This is optimal for developers focusing on personal, on-premise projects or testing their scripts locally without interfacing with a remote backend.

Example Output:

Logged out successfully from local backend.

Use case 4: Display help

Code:

pulumi logout --help

Motivation: Sometimes, users require guidance or a refresher on the functionalities and options available with the pulumi logout command. Accessing the help documentation directly through the command line allows users to quickly find details on usage, parameters, and examples without needing to search online or access additional resources.

Explanation:

• --help: This flag activates the display of help documentation associated with the pulumi logout command. It provides users with detailed descriptions of all command options, facilitating better understanding and informed decision-making.

Example Output:

Usage: pulumi logout [OPTIONS] [backend_url]
Log out of the Pulumi cloud.
Options:
  --local   Log out of using local mode
  --all     Log out of all backends
  -h, --help  Show command help

Conclusion:

This article provides comprehensive examples and explanations for using the pulumi logout command. Whether you are working on specific cloud backends, managing multiple environments, maintaining local settings, or seeking assistance with the command’s options, these use cases highlight the versatility and utility of pulumi logout in maintaining a secure and manageable infrastructure environment.
