Command upspin-ui presents a web interface to the Upspin name space, and also provides a facility to sign up an Upspin user and deploy an upspinserver to Google Cloud Platform. It operates as the user in the specified config. If no config is available at the specified path, the user is prompted to sign up an Upspin user.
The Upspin browser presents two navigation panes.
Each browser pane lists the contents of an Upspin directory. The directory is shown in a text box at the top of each pane.
You can navigate directly to a specific Upspin path by typing (or pasting) it into the text box and pressing the enter key. The button to the left of the text box navigates to the parent of the current directory.
Clicking the name of an entry will attempt to download the entry with your web browser or, if the entry is a directory, will navigate to that directory.
At startup, the left pane displays the current user's root and the right pane displays the path firstname.lastname@example.org.
The checkboxes beside each entry permit the (de-)selection of entries. The checkbox at the top of each list of entries (de-)selects all entries in that directory.
The "Delete" button recursively deletes the selected files and directories.
The "Copy" button recurisively copies the selected files and directories to the directory displayed in the opposite pane.
The "Make directory" button creates a directory in the pane's current directory.
The "Refresh" button reloads the contents of the directory and displays it.
The info buttons (a little "i" in a circle, to the right of each file) display extended information for a given directory entry.
The signup process creates a config file at the location provided by the -config flag. The flag's default value is $HOME/upspin/config. Signup also generates key files and puts them in the directory $HOME/.ssh/$USER, where $USER is the Upspin user name.
The upspinserver deployment process records its state in a file with the same name as the config file with the additional suffix ".gcpState". This state file is used to resume the deployment process should the upspin-ui program crash or be terminated by the user. Once deployment is complete this file may be removed. Deployment also generates key files which it puts in $HOME/.ssh/$USER, where $USER is the Upspin user name of the server being deployed.
During the signup and deployment processes, upspin-ui logs debugging information to $HOME/upspin/log/upspin-ui.log.
