fabric_ctl (e.g., Fabric Control) is a command line application that allows you to administer the fabric. Fabric Control connects to the fabric using an MCAST address and port. The Fabric Control executable fabric_ctl is found in FABRIC_HOME.
fabric_ctl -d <fabric-address>:<admin-port> -u <fabric-admin-username>:<fabric-admin-password> <action>
fabric_ctl -d 239.255.0.1:30000 -u fabric-admin/fabric-admin query all
If you plan on using the fabric_ctl command often, it may benefit you to set the FABRIC_ADMIN_ADDRESS address environment variables so that you do not have to type -d <fabric-address>:<admin-port> every time.
In addition, you can log into a specific fabric so that you would not need to provide the -u <fabric-admin-username>:<fabric-admin-password> on subsequent commands.
 | If fabric_ctl returns the message "versions of fabric_ctl and fabric are not compatible", this indicates that the version of the fabric_ctl utility executable is older than the version of the fabric software installed on your workers. You will need to upgrade the fabric_ctl utility to match. |
To enable an administrator to manage the fabric
- If needed, add the administrator's user name and password to the user.cfg file using Fabric User (fabric_user).
- Add the user name to the fabric-admin group in the group.cfg file, and increment the file's version number.
- Use fabric_ctl to redeploy the user.cfg and group.cfg files to the fabric. You will need to do so as an already authorized administrative user.
