SSH Settings
Config namespace: config.ssh
The settings within config.ssh relate to configuring how Vagrant
will access your machine over SSH. As with most Vagrant settings, the
defaults are typically fine, but you can fine tune whatever you'd like.
Available Settings
config.ssh.username - This sets the username that Vagrant will SSH
as by default. Providers are free to override this if they detect a more
appropriate user. By default this is "vagrant," since that is what most
public boxes are made as.
config.ssh.password - This sets a password that Vagrant will use to
authenticate the SSH user. Note that Vagrant recommends you use key-based
authentication rather than a password (see private_key_path) below. If
you use a password, Vagrant will automatically insert a keypair if
insert_key is true.
config.ssh.host - The hostname or IP to SSH into. By default this is
empty, because the provider usually figures this out for you.
config.ssh.port - The port to SSH into. By default this is port 22.
config.ssh.guest_port - The port on the guest that SSH is running on. This
is used by some providers to detect forwarded ports for SSH. For example, if
this is set to 22 (the default), and Vagrant detects a forwarded port to
port 22 on the guest from port 4567 on the host, Vagrant will attempt
to use port 4567 to talk to the guest if there is no other option.
config.ssh.private_key_path - The path to the private key to use to
SSH into the guest machine. By default this is the insecure private key
that ships with Vagrant, since that is what public boxes use. If you make
your own custom box with a custom SSH key, this should point to that
private key.
You can also specify multiple private keys by setting this to be an array. This is useful, for example, if you use the default private key to bootstrap the machine, but replace it with perhaps a more secure key later.
config.ssh.forward_agent - If true, agent forwarding over SSH
connections is enabled. Defaults to false.
config.ssh.forward_x11 - If true, X11 forwarding over SSH connections
is enabled. Defaults to false.
config.ssh.forward_env - An array of host environment variables to forward to
the guest. If you are familiar with OpenSSH, this corresponds to the SendEnv
paramter.
config.ssh.forward_env = ["CUSTOM_VAR"]
config.ssh.insert_key - If true, Vagrant will automatically insert
a keypair to use for SSH, replacing Vagrant's default insecure key
inside the machine if detected. By default, this is true.
This only has an effect if you don't already use private keys for
authentication or if you are relying on the default insecure key.
If you don't have to care about security in your project and want to
keep using the default insecure key, set this to false.
config.ssh.proxy_command - A command-line command to execute that receives
the data to send to SSH on stdin. This can be used to proxy the SSH connection.
%h in the command is replaced with the host and %p is replaced with
the port.
config.ssh.pty - If true, pty will be used for provisioning. Defaults to false.
This setting is an advanced feature that should not be enabled unless absolutely necessary. It breaks some other features of Vagrant, and is really only exposed for cases where it is absolutely necessary. If you can find a way to not use a pty, that is recommended instead.
config.ssh.shell - The shell to use when executing SSH commands from
Vagrant. By default this is bash -l. Note that this has no effect on
the shell you get when you run vagrant ssh. This configuration option
only affects the shell to use when executing commands internally in Vagrant.
config.ssh.sudo_command - The command to use when executing a command
with sudo. This defaults to sudo -E -H %c. The %c will be replaced by
the command that is being executed.
