juju bootstrap command to create a controller (and model) for a given
juju bootstrap [options] <cloud name> <controller name>
juju help bootstrap for details on this command or see the
command reference page.
<controller name> is optional. If one is not supplied, then a name is
assigned based on the cloud and region.
juju bootstrap aws/us-east-1
This creates a new controller called
aws-us-east-1 in that cloud and region.
Bootstrap has many options. Some commonly used options are described here with examples.
Because Xenial is the current LTS release, we do not have to mention it specifically. For our example, we name the controller lxd-xenial and instruct it to use the local lxd cloud.
juju bootstrap lxd lxd-xenial
The '--upload-tools' option is used to make agent software available that is
more recent than the default binary. This is done when some features may not
yet be compiled in to the agent for the Ubuntu release being installed. Note
that Juju will default to the latest LTS (see
distro-info --lts command).
The '--config' option allows you to pass configuration values during bootstrap as arguments. If you do this, the values you use take precedence over any default settings.
juju bootstrap --upload-tools --config default-series=trusty \ lxd lxd-trusty
The example uses a previously defined configuration file called config-rackspace.yaml. Many clouds are available, see Clouds. Note that values passed using '--config' as above will take precedence over values included in a file. This is important if you use both a config file and state one or more config values while bootstrapping.
juju bootstrap \ --upload-tools --config=~/config-rackspace.yaml \ --config image-stream=daily rackspace controller-rackspace
This example provides 4G of RAM to the local lxd controller we create. For more details about constraints, see Constraints.
juju bootstrap --constraints="mem=4G" lxd lxd-xenial
If you omit the optional controller name here, the new controller will be
named using the name of the cloud,
juju bootstrap --constraints="mem=4G" lxd
The Clouds page details listing available clouds and how the list denotes default regions for each. To specify a different region during controller creation, use:
juju bootstrap aws/us-west-2 mycontroller
This is an instance where using the default controller name could be especially
handy, as omitting the
mycontroller name will cause your new controller to
be named using the non-default region, specifically naming it
juju bootstrap aws/us-west-2
You can change the default timeout and retry delays used by Juju by setting the following keys in your configuration:
|bootstrap-timeout||600||How long to wait for a connection to the controller|
|bootstrap-retry-delay||5||How long to wait between connection attempts to a controller|
|bootstrap-address-delay||10||How often to refresh controller addresses from the API server|
For example, to increase the timeout between the client and the controller from 10 minutes to 15, enter the value in seconds:
juju bootstrap --config bootstrap-timeout=900 lxd lxd-faraway
