Trent's Tech Tips

Well, just under 30 days ago, Oracle announced a series of resources you can use in OCI for free. One thing that had stopped me signing up and trying out OCI in the past was that I wanted to make the best use of the free credits, and knowing I wouldn't get a full chance to try things out in the 30 days, I didn't want to sign up prematurely. Now that they offer some free resources, this prompted me to sign up. I am now at the end of the 30-day period where I have some credits to use non-free resources. One final thing I wanted to try out was attaching multiple VNIC (Virtual network interface card) to a single compute instance. One use-case of these is that you may want a machine accessible in 2 different networks. It's not just a matter of attaching it in the OCI console - to bring the interface up you have to perform a couple of extra steps. When I was first trying this, I didn't read the docs and figured I would just have to edit the interface config script and bri

There are two functionalities in OCI that we can leverage in order to support logging - Streaming and Events service. With the events service we can define on which events to match whereby you specify a service name and the corresponding event types. So for object storage, we log events based on create, update and delete:  The next part is that we can define the action type, with three possible options: Streaming Notifications Functions For this article, we are looking into Streaming. So, the first step is to go ahead and make a stream. Nothing too complex here, just go to the Analytics, Streaming menu in the console, and create a new stream. When you create it, you specify a retention policy where it's defaulted to 24 hours. SO I will leave it at the default. Actually, I'm leaving it all at the default. The next step is that we need to define an IAM policy so that cloud events can leverage this streaming functionality. So, head over to IAM and create a new poli
