Grande pergunta! O Juju Quickstart é um aplicativo wrapper fácil de usar em torno do juju-deployer e do Juju. O propósito da vida útil do Quickstart é ajudar os usuários a iniciar o Juju o mais rápido possível instalando o Juju (se ainda não estiver instalado), fornecendo uma interface do usuário para gerenciar suas definições de ambiente, inicializando esses ambientes e obtendo uma GUI Juju nesse ambiente da maneira mais leve possível. O recurso final é permitir que você implante um pacote da loja de charadas ( link ) ou um pacote local que você tenha no disco.
O juju-deployer é uma ferramenta Python de propósito único usada para implantar bundles de qualquer local - como github, ramificações da barra de ativação, repositórios de charme locais e / ou arquivos do implementador. O objetivo geral do juju-deployer era ser consumido diretamente pelos desenvolvedores ou consumido pelos aplicativos. Ele fornece um controle mais aprofundado dessas implantações de pacote, dando suporte a coisas como nova tentativa em caso de falha.
O Juju Quickstart usa o deployer, mas o envolve em um shell fácil de usar, pois apresenta uma maneira única de começar com o Juju como seu objetivo principal.
No entanto, é importante observar que o deployer expõe algumas funcionalidades adicionais que você não encontrará no Juju Quickstart - como a implantação diretamente dos repositórios do GitHub. (isso está sujeito a alterações)
Exemplos:
juju deployer -c /path/to/my/bundle
juju quickstart path/to/my/bundle
juju deployer -c bundle:mediawiki-single/7
juju quickstart mediawiki-single/7

exit.
-B, --bootstrap Bootstrap specified environment, blocks until ready
-s DEPLOY_DELAY, --deploy-delay DEPLOY_DELAY
Time in seconds to sleep between 'deploy' commands, to
allow machine provider to process requests. On
terminate machines this also signals waiting for
machine removal.
-e JUJU_ENV, --environment JUJU_ENV
Deploy to a specific Juju environment.
-o OVERRIDES, --override OVERRIDES
Override *all* config options of the same name across
all services. Input as key=value.
--series SERIES Override distro series in config files
-v, --verbose Verbose output
-W, --watch Watch environment changes on console
-r RETRY_COUNT, --retry RETRY_COUNT
Resolve CLI and unit errors via number of retries
(default: 0). Either standalone or in a deployment
--ignore-errors Proceed with the bundle deployment ignoring units
errors. Unit errors are also automatically ignored if
--retry != 0
--diff Generate a delta between a configured deployment and a
running environment.
-w REL_WAIT, --relation-wait REL_WAIT
Number of seconds to wait before checking for relation
errors after all relations have been added and
subordinates started. (default: 60)

[BUNDLE]
Juju Quickstart is a Juju plugin which allows for easily setting up a Juju
environment in very few steps. The environment is bootstrapped and set up so
that it can be managed using a Web interface (the Juju GUI).
positional arguments:
BUNDLE The optional bundle to be deployed. The bundle can be:
1) a bundle path as shown in jujucharms.com, e.g.
"mediawiki-single" or "django".
Non promulgated bundles can be requested providing
the user, e.g. "u/bigdata-dev/apache-analytics-sql".
A specific bundle revision can also be requested,
e.g. "mediawiki-scalable/7".
If not specified, the most recent revision is used;
2) a jujucharms.com full URL of the bundle detail page,
with or without the revision. e.g.
"https://jujucharms.com/mongodb-cluster/4" or
"https://jujucharms.com/openstack";
3) a URL ("http:" or "https:") to a YAML/JSON, e.g.
"https://raw.github.com/user/my/master/bundle.yaml";
4) a local path to a YAML/JSON file with ".yaml" or
".json" extension, e.g. "~/bundles/django.yaml";
5) a legacy fully qualified bundle URL, starting with
"bundle:", e.g. "bundle:mediawiki/single".
Non promulgated bundles can be requested providing
the user, e.g. "bundle:~user/mediawiki/single".
A specific bundle revision can also be requested,
e.g. "bundle:~myuser/mediawiki/42/single".
If not specified, the last bundle revision is used.
Note that this form is DEPRECATED, and a deprecation
warning is printed suggesting the new value to use
optional arguments:
-h, --help show this help message and exit
-e ENV_NAME, --environment ENV_NAME
The name of the Juju environment to use (amazon)
-n BUNDLE_NAME, --bundle-name BUNDLE_NAME
The name of the bundle to use.
This must be included in the provided bundle YAML/JSON.
Specifying the bundle name is not required if the
bundle YAML/JSON only contains one bundle. This option
is ignored if the bundle file is not specified
-i, --interactive Start the environments management interactive session
--environments-file ENV_FILE
The path to the Juju environments YAML file
(/home/charles/.juju/environments.yaml)
--gui-charm-url CHARM_URL
The Juju GUI charm URL to deploy in the environment.
If not provided, the last release of the GUI will be
deployed. The charm URL must include the charm version,
e.g. "cs:~juju-gui/precise/juju-gui-162". This option is
ignored if the GUI is already present in the environment
--no-browser Avoid opening the browser to the GUI at the end of the
process
--distro-only Do not use external sources when installing and setting up Juju
--ppa Use external sources when installing and setting up Juju
(enabled by default, use --distro-only to disable)
--version show program's version number and exit
--debug Turn debug mode on. When enabled, all the subcommands
and API calls are logged to stdout, and the Juju
environment is bootstrapped passing --debug
--description Show program's description and exit
--upload-tools upload local version of tools before bootstrapping
--upload-series UPLOAD_SERIES
upload tools for supplied comma-separated series list
--constraints CONSTRAINTS
If constraints are specified, they will apply to the machine
provisioned for the Juju state server.
They will also be set as default constraints on the
environment for all future machines, exactly as if the
constraints were set with "juju set-constraints".
Features include the following:
* New users are guided, as needed, to install Juju, set up SSH keys, and
configure it for first use.
* Juju environments can be created and managed from a command line interactive
session.
* The Juju GUI is automatically installed, adding no additional machines
(installing on an existing state server when possible).
* Bundles can be deployed, from local files, HTTP(S) URLs, or the charm store,
so that a complete topology of services can be set up in one simple command.
* Quickstart ends by opening the browser and automatically logging the user
into the Juju GUI.
* Users with a running Juju environment can run the quickstart command again to
simply re-open the GUI without having to find the proper URL and password.
To start Juju Quickstart, run the following:
juju-quickstart [-i]
Once Juju has been installed, the command can also be run as a juju plugin,
without the hyphen ("juju quickstart").
