Installation(Ubuntu)
#sudo add-apt-repository ppa:juju/stable (我们使用1.25)
#sudo apt-get update && sudo apt-get install juju-core
Configuring
linux目录下有个配置文件;
~/.juju/environments.yaml
#juju generate-config
# This is the Juju config file, which you can use to specify multiple # environments in which to deploy. See https://juju.ubuntu.com/docs # for more information # An environment configuration must always specify at least the # following information: # - name (to identify the environment) # - type (to specify the provider) # In the following example the name is "myenv" and type is "ec2". # myenv: # type: ec2 # Values in <brackets> below need to be filled in by the user. # Optional attributes are shown commented out, with # a sample value or a value in <brackets>. # There are several settings supported by all environments, all of which # are optional and have specified default values. For more info, see the # Juju documentation. # The default environment is chosen when an environment is not # specified using any of the following, in descending order of precedence: # 1. -e or --environment command line parameter, passed after the command, e.g. # $ juju add-unit -e myenv myservice # 2. By setting JUJU_ENV environment variable. # 3. Using the juju switch command like this: # $ juju switch myenv # # You can control how Juju harvests machines by using the # provisioner-harvest-mode setting. Harvesting is a process wherein # Juju attempts to reclaim unused machines. # # Options are: # # Don\'t harvest any machines. # provisioner-harvest-mode: none # # Only harvest machines that Juju knows about and are dead. # provisioner-harvest-mode: destroyed # # Only harvest machines that Juju doesn\'t know about. # provisioner-harvest-mode: unknown # # Harvest both dead and unknown machines. # provisioner-harvest-mode: all default: amazon environments: # https://juju.ubuntu.com/docs/config-local.html local: type: local # root-dir holds the directory that is used for the storage files and # database.

Override the value if you have multiple local # providers, or if the default port is used by another program. # # storage-port: 8040 # network-bridge holds the name of the LXC network bridge to use. # Override if the default LXC network bridge is different. # # # network-bridge: lxcbr0 # The default series to deploy the state-server and charms on. # Make sure to uncomment the following option and set the value to # precise or trusty as desired. # # default-series: trusty # Whether or not to refresh the list of available updates for an # OS.
