Install os-refresh-config.
|
|
|
|
os-refresh-config uses run-parts to run scripts in a pre-defined set
|
|
of directories. Its intended purpose is to quiesce (pre-configure.d),
|
|
configure (configure.d), migrate (migration.d), and then activate
|
|
(post-configure.d) a configuration on first boot or in response to Heat
|
|
Metadata changes.
|
|
|
|
To cause a script to be run on every os-refresh-config run, install
|
|
it into one of the following directories:
|
|
````
|
|
/opt/stack/os-refresh-config/pre-configure.d
|
|
/opt/stack/os-refresh-config/configure.d
|
|
/opt/stack/os-refresh-config/migration.d
|
|
/opt/stack/os-refresh-config/post-configure.d
|
|
```
|
|
|
|
If you want to have os-refresh-config run on any updates to a particular
|
|
Resource in the heat stack, you will need at the minimum the following snippet
|
|
of json in this instance's Metadata:
|
|
|
|
{
|
|
"OpenStack::Config": {
|
|
"heat":
|
|
"access_key_id": {"Ref": "ApiKeyResource"},
|
|
"secret_key": {"Fn::GetAtt": [ "ApiKeyResource", "SecretAccessKey" ]},
|
|
"refresh": [ {"resource": "SomeResource"} ],
|
|
"stack": {Ref: 'AWS::Stack'},
|
|
"region": {Ref: 'AWS::Region'}
|
|
}
|
|
}
|
|
}
