Install os-refresh-config.
Install os-refresh-config
=========================
os-refresh-config uses run-parts to run scripts in a pre-defined set
os-refresh-config uses dib-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
@ -8,33 +9,32 @@ 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-config-refresh/pre-configure.d
/opt/stack/os-config-refresh/configure.d
/opt/stack/os-config-refresh/migration.d
/opt/stack/os-config-refresh/post-configure.d
```
/opt/stack/os-config-refresh/pre-configure.d
/opt/stack/os-config-refresh/configure.d
/opt/stack/os-config-refresh/migration.d
/opt/stack/os-config-refresh/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'}
{
"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'}
}
}
}
}
}
If you would like to signal a wait condition at the end of
post-configure.d, a generic name of 'completion-handle' can be used
like so:
{
"completion-handle": {"Ref": "CompletionHandleName"}
}
{
"completion-handle": {"Ref": "CompletionHandleName"}
}
