Appends new host entries into the compute section. If any of the newly appended entries match the host of a previous compute section entry, the previous entry is removed. The resulting merged configuration file contents are returned. This function has no side effects, and does not directly change the contents of the configuration file.

In most cases, it is sufficient to run: $ {command} Each instance will be given an alias of the form `NAME.ZONE.PROJECT`. For example, if `example-instance` resides in `us-central1-a`, you can SSH to it by running: $ ssh example-instance.us-central1-a.MY-PROJECT On some platforms, the host alias can be tab-completed, making the long alias less daunting to type. The aliases created interface with SSH-based programs like *scp(1)*, so it is possible to use the aliases elsewhere: $ scp ~/MY-FILE example-instance.us-central1-a.MY-PROJECT:~ Whenever instances are added, removed, or their external IP addresses are changed, the remove command must be run to clear the existing configuration and then the command can set executed to set the configuration to the current state. This command ensures that the user's public SSH key is present in the project's metadata. If the user does not have a public SSH key, one is generated using *ssh-keygen(1)* (if the `--quiet` flag is given, the generated key will have an empty passphrase). ## EXAMPLES To populate SSH config file with Host entries from each running instance, run: $ {command} To remove the change to the SSH config file by this command, run: $ {command} --remove c[RRU5 URSSR [ R 5S9 URSSSS9 URSSS S9 g ) zPSet up arguments for this command.
