Pulumi v3.208.0 introduces the ability to configure all CLI flags as environment variables, streamlining the process of using consistent CLI options across teams and alleviating the need to remember repetitive flags for multiple commands. This feature is especially beneficial in scenarios such as refreshing state before operations or skipping prompts in CI environments by using environment variables instead of flags. Users can set these variables by prefixing the flag name with PULUMI_OPTION_ and replacing dashes with underscores, with the environment variable taking precedence over command line flags. This enhancement is particularly useful when combined with direnv, allowing project-specific defaults to be set in a .envrc file for automatic application within a directory. This development aims to simplify configuration and management of operation defaults across various environments and invites users to provide feedback through GitHub, X, or Community Slack.
