If you want to start or stop all of your OKE data plane cluster nodes you must go to all the nodes and execute the action one by one.
The current post depicts a kubectl plugin extension created for helping you to start/stop your oke clusters.
NOTES: The tool has been developed and tested in Mac. In addition the tool utilises jq which is installed automatically in case it is not.
Take a look at this github page for instructions and code. Here an example of the tool at work:
NOTE: The tool is gonna be submitted soon for approval in the krew-index (like a package manager for kubectl plugins), meanwhile you can install it locally as follows:
git clone https://github.com/javiermugueta/oke-cluster-start-stop.git
cd oke-cluster-start-stop
kubectl krew install --manifest=oke-cluster-start-stop.yaml --archive=oke-cluster-start-stop-1.0.0.zip
In addition you can execute the tool as a stand alone script as well.
Oracle SaaS API’s have a structure that is equal for all the “business entities” across the different modules (Finance, Loyalty, Supply Chain, …) such as invoices, expenses, loyalty transactions and so on. Let’s analyze the pattern. In this episode, we are focusing on the “Get all xxx” methods because it conforms a pattern that we’ll utilise in a sooner construct which we are working on for building a tool that extracts and publishes changes in the data in near-realtime.
Verb
Verb for all of them is obviously GET
Endpoint
Endpoint is <fqdnurl>/<endpoint> where
<fqdn> is the server url such as https://iiii-eeee.fa.em2.oraclecloud.com
<endpoint> is the API endpoint provided in the documentation such as /fscmRestApi/resources/11.13.18.05/invoices
Data Retrieved
If you execute the API call and data exists, conditions are valid and the user you are using for the connection has privileges to read, a JSON structure is retrieved up to the number of records in the limit parameter (default 25). If more records exist it is notified in the hasMore field in the response.
Parameters
expand: Includes child records of the entity, you can specify which childs to include or all for example ?expand=invoiceLines (tip: if onlyData is false (default) the links provide you the name of the child entities)
fields: If you don't want all the fields in the response, include the names of the fields expected
limit: maximum number of records per call execution
offset: the ordinal number of the set of records retrieved according to the total and the limit parameter. For example if limit is 5 and you want the records from 6 to 10, offset must be set to 1
onlyData: by default, response JSON includes child objects links, putting this value to false disables that option
orderBy: fields and order criteria for retrieving data such as ?orderBy=InvoiceId:asc,SupplierSite:desc
q: the filter condition to get data such as ?q=InvoiceAmount>1000
totalResults: by default is false so total records retrieved are not evaluated, if true they are counted with the drawback of a more computation cost and probably lower response time and performance
totalResults effectGet all banks REST APIGet all expense records APIGet all invoices API
Example
In the following example we are requesting invoices and their lines with an amount greater than 1000 indicating that we want to know the number of invoices that accomplish the criteria
curl -X GET -k -H 'Content-Type: application/vnd.oracle.adf.resourceitem+json' -u jxvxxr.mxgxxtx@xrxclx.cxm:password "https:/iiii-eee.fa.em2.oraclecloud.com//fscmRestApi/resources/11.13.18.05/invoices?limit=5&totalResults=true&q=InvoiceAmount>1000&expand=invoiceLines&onlyData=true"

In this episode we are explaining one of the many mechanisms for executing actions when changes happen in the Cloud App Environment.
In this particular case, as an example, we are calling an external REST service hosted in a kubernetes cluster, that implements a counter. Every time we create or modify a Contact, the external service is called.
Hands on!
Enter in the environment with a user with al least ORA_ASM_APPLICATION_IMPLEMENTATION_CONSULTANT_JOB
Go to “Manage Sandboxes”:
Create a new sandbox and set active:
Go to Application Composer:
Click on “Common Setup-Web Services”:
Create a new Web Service:
Select REST/SOAP appropriately:
Put the information of your service endpoint:
Search for the “Contact” business object, click on “Server Scripts”, then “triggers”, then click on “create”:
Crate a trigger of type “After Create”:
Go to the Web Services tab on the right pane, locate the service you want to invoke and click on “insert”:
The code invoked when a new contact is created is put in the editor. Save it.
NOTE: You can create another trigger for other events, such as “AfterTransactionPosted”, etc.
Let’s test it!
Check the status of the external web service:
Go to the Contacts Menu:
Create a new contact, for example Abelardo Pirindiki:
Check the status of the external service and see it has been called:
