Placement directive indicating an instance to bootstrap
Used without arguments, bootstrap will step you through the process of initializing a Juju cloud environment. Initialization consists of creating a ‘controller’ model and provisioning a machine to act as controller.
We recommend you call your controller ‘username-region’ e.g. ‘fred-us-east-1’ See
--clouds for a list of clouds and credentials.
--regions for a list of available regions for a given cloud. Credentials are set beforehand and are distinct from any other configuration (see
The ‘controller’ model typically does not run workloads. It should remain pristine to run and manage Juju’s own infrastructure for the corresponding cloud. Additional (hosted) models should be created with
juju create- model for workload purposes.
Note that a ‘default’ model is also created and becomes the current model of the environment once the command completes. It can be discarded if other models are created.
--bootstrap-constraints is used, its values will also apply to any future controllers provisioned for high availability (HA).
--constraints is used, its values will be set as the default constraints for all future workload machines in the model, exactly as if the constraints were set with juju set-model-constraints.
It is possible to override constraints and the automatic machine selection algorithm by assigning a “placement directive” via the
--to option. This dictates what machine to use for the controller. This would typically be used with the MAAS provider (
Available keys for use with
--config can be found here:
You can change the default timeout and retry delays used during the bootstrap by changing the following settings in your configuration (all values represent number of seconds):
# How long to wait for a connection to the controller bootstrap-timeout: 600 # default: 10 minutes # How long to wait between connection attempts to a controller address. bootstrap-retry-delay: 5 # default: 5 seconds # How often to refresh controller addresses from the API server. bootstrap-addresses-delay: 10 # default: 10 seconds
Private clouds may need to specify their own custom image metadata and tools/agent. Use
--metadata-source whose value is a local directory. By default, the Juju version of the agent binary that is downloaded and installed on all models for the new controller will be the same as that of the Juju client used to perform the bootstrap.
However, a user can specify a different agent version via
--agent-version option to bootstrap command. Juju will use this version for models’ agents as long as the client’s version is from the same Juju release series.
In other words, a 2.2.1 client can bootstrap any 2.2.x agents but cannot bootstrap any 2.0.x or 2.1.x agents.
The agent version can be specified a simple numeric version, e.g. 2.2.4. For example, at the time when 2.3.0, 2.3.1 and 2.3.2 are released and your agent stream is ‘released’ (default), then a 2.3.1 client can bootstrap: * 2.3.0 controller by running
... bootstrap --agent-version=2.3.0 ...; * 2.3.1 controller by running
... bootstrap ...; * 2.3.2 controller by running
However, if this client has a copy of codebase, then a local copy of Juju will be built and bootstrapped - 184.108.40.206.
