# Shared Model Config QA #

## Common steps ##

    $ juju add-cloud awstest ~/Sync/juju/2.0/dev-clouds.yaml
    $ juju bootstrap awstest reed/aws/us-west-1

## Testing modelconfig ## 

Test that we get defaults from our configuration. Here we get the controller
level setting at the model level for no-proxy since this is our default model.
We get xenial as our default series as set in the controller config and
development is set to false which comes from the provider default config. 

    $ juju model-config
    # output elided except some bits to show expected values
    Attribute                     From        Value
    ...
    default-series                controller  xenial
    development                   default     false
    enable-os-upgrade             controller  false
    ...
    no-proxy                      model       https://local
    ...
    
Let's add a model in us-east-1 to make sure it correctly inherits.

    $ juju add-model east1 us-east-1
    $ juju model-config 
    Attribute                     From        Value
    ...
    default-series                controller  xenial
    development                   default     false
    enable-os-upgrade             controller  false
    ...
    no-proxy                      region      https://foo-east
    ...

Then we set some values and verify they are set and that the source of the
settings are correctly updated.  

    $ juju model-config no-proxy=not-east development=true default-series=trusty
    $ juju model-config
    Attribute                     From        Value
    ...
    default-series                model       trusty
    development                   model       true
    enable-os-upgrade             controller  false
    firewall-mode                 default     instance
    ...
    no-proxy                      model       not-east
    ... 

Now if we create a model in us-west-1 and ensure it has it's own settings.

    $ juju add-model west1 us-west-1
    $ juju model-config
    Attribute                     From        Value
    ...
    default-series                controller  xenial
    development                   default     false
    ...
    no-proxy                      region      https://foo-west
    ...

Switching back to the east we can reset settings, and then verify we get our
original defaults back. Fo good measure we also set another setting here to
ensure that we can set and reset at the same time...

    $ juju switch east1
    $ juju model-config --reset development,default-series,no-proxy \
        apt-ftp-proxy=some-proxy
    $ juju model-config
    Attribute                     From        Value
    ...
    apt-ftp-proxy                 model       some-proxy
    ...
    default-series                controller  xenial
    development                   default     false
    no-proxy                      region      https://foo-east
    ...


## Model Defaults Testing ##

Let's kill the models and start over for model-defaults

    $ juju destroy-model east1 -y
    $ juju destroy-model west1 -y

Let's make sure the defaults have loaded correctly when we created our
controller.

    $ juju  model-defaults
    Attribute                   Default           Controller
    ...
    default-series              xenial            xenial
    ...
    enable-os-upgrade           true              false
    ...
    ftp-proxy                   ""                -
    image-stream                released          -
    ...
    no-proxy                    ""                https://local
      us-east-1                 https://foo-east  -
      us-west-1                 https://foo-west  -
    ...

Set another value in east and ask for it.

    $ juju model-defaults us-east-1 ftp-proxy=ftp://east
    $ juju model-defaults ftp-proxy
    Attribute    Default     Controller
    ftp-proxy    ""          -
      us-east-1  ftp://east  -


Just ask for no-proxy which has settings in multiple regions.

    $ juju model-defaults no-proxy
    Attribute    Default           Controller
    no-proxy     ""                https://local
      us-east-1  https://foo-east  -
      us-west-1  https://foo-west  -

Ask for only settings specific to us-east-1.

    $ juju juju model-defaults us-east-1
    Attribute    Default           Controller
    ftp-proxy    ""                -
      us-east-1  ftp://east        -
    no-proxy     ""                https://local
      us-east-1  https://foo-east  -

Ask only for no-proxy in us-east-1.

    $ juju model-defaults us-east-1 no-proxy
    Attribute    Default           Controller
    no-proxy     ""                https://local
      us-east-1  https://foo-east  -

Let's change some defaults and make sure they work.

    $ juju model-defaults enable-os-upgrade=true default-series=trusty
    $ juju  model-defaults  
    Attribute                   Default           Controller
    ...
    default-series              xenial            trusty
    ...
    disable-network-management  false             -
    ...
    enable-os-upgrade           true              true
    ...

Let's change some region settings and reset ftp-proxy.

    $ juju model-defaults --reset ftp-proxy us-east-1 default-series=xenial enable-os-upgrade=false
    $ juju model-defaults default-series
    Attribute       Default  Controller
    default-series  xenial   trusty
      us-east-1     xenial   -

    $ juju model-defaults enable-os-upgrade
    Attribute          Default  Controller
    enable-os-upgrade  true     true
      us-east-1        false    -

We should get an error if we ask for a non existent setting.

    $ juju model-defaults us-east-1 ftp-proxy
    ERROR there are no default model values for "ftp-proxy" in region "us-east-1"

Let add-models and make sure they inherit.

West 1:

    $ juju add-model west1 us-west-1
    $ juju model-config
    Attribute                     From        Value
    ...
    default-series                controller  trusty
    ...
    enable-os-upgrade             default     true
    ...
    no-proxy                      region      https://foo-west
    ...

East 1

    $ juju add-model east1 us-east-1
    $ juju model-config
    Attribute                     From        Value
    ...
    default-series                region      xenial
    ...
    enable-os-upgrade             model       false
    ...
    no-proxy                      region      https://foo-east

West 2:

    $ juju add-model west2 us-west-2
    $ juju model-config
    Attribute                     From        Value
    ...
    default-series                controller  trusty
    ...
    enable-os-upgrade             default     true
    ...
    no-proxy                      controller  https://local

Let's kill those models:

    $ juju switch default 
    for c in east1 west1 west2;do juju destroy-model -y $c;done    

Reset some settings we set earlier. 

    $ juju model-defaults --reset default-series,enable-os-upgrade,no-proxy
    Attribute                   Default           Controller
    ...
    default-series              xenial            -
      us-east-1                 xenial            -
    ...
    enable-os-upgrade           true              -
      us-east-1                 false             -
    ...
    no-proxy                    ""                -
      us-east-1                 https://foo-east  -
      us-west-1                 https://foo-west  -
    ...

Now reset no-proxy in us-west-1 and test asking for all region settings.

    $ juju model-defaults --reset no-proxy us-west-1
    $ juju model-defaults awstest/us-west-1
    ERROR there are no default model values in region "us-west-1"
    $ juju model-defaults awstest/us-east-1
    Attribute          Default           Controller
    default-series     xenial            -
      us-east-1        xenial            -
    enable-os-upgrade  true              -
      us-east-1        false             -
    no-proxy           ""                -
      us-east-1        https://foo-east  -

And remove the remote machines...

    $ juju kill-controller reed/aws/us-west-1 -y
