Root commands
Outside of groups, gcloud contains a few additional commands that do not belong to a specific group. These commands are available at the root level of CLI and include docker, feedback, help, info, init, and version. The gcloud docker command allows users to interact directly with the Google Container Registry. The other commands offer operations on CLI itself. Using gcloud info will display a detailed view of your current configuration and environment, including the active account and the project you are operating against. This is a very useful command to quickly check that you are running commands in the desired context.
Find a bug or have a suggestion on how to improve the Google Cloud SDK? Try running gcloud feedback to quickly create a message and post it to one of Google's support channels. This command will allow you to specify a recently run command and an optional log file to be included in the submission. The result is a quick and easy way to provide meaningful feedback to the Google team.
