Key Questions Answered
What are the new top-level commands introduced in flyctl v0.0.137?
The new top-level commands include 'init', 'destroy', 'list apps', 'move', 'restart', 'resume', and 'suspend'. These commands replace the deprecated 'apps' subcommand, streamlining the command structure for better usability.
How has the flyctl command structure changed?
The flyctl command structure has shifted to an app-centric style, where commands that previously fell under the 'apps' subcommand are now available as top-level commands. This change simplifies command usage and enhances user experience.
What usability improvements have been made in the flyctl init command?
The 'init' command now offers a selection of builders or the option to use a Dockerfile. If no Dockerfile is present, it can generate a simple hello world deployment, making it easier for users to start their applications.
What changes have been made regarding secrets in flyctl?
Setting and unsetting secrets on suspended deployments is now blocked, and doing so will start a deployment monitor unless the app is undeployed. Users can use the --detach flag to return before starting the monitor.
