I have an old post how to create three instances in OCI with modules using Terraform 0.11 but since 0.12 came out I’ve been wanting to rewrite it to show what we can achieve with new features introduced in TF 0.12. In this post I will once again create those instances but now the modules…
OCI Autoscaling with Events Service and Terraform 0.12
Some time ago I published a post where I took a test drive with OCI Autoscaling. Now after an eventful summer I think it’s time to retest Autoscaling mainly due to some enhancements we have seen. If you want to get more details on Autoscaling then please read the older post and remarks I’ve made…
Rewriting Terraform security list configuration in OCI with Terraform 0.12
I’ve been a big fan of Terraform for quite some time but one of the things I have been complaining about has been some things which have not been possible when you use Terraform modules. Why do we use modules? It gives us a way to reuse our code so that each resource creation is…
Security in Oracle Cloud Infrastructure and why you should care less about it
I recently attended Accenture’s Oracle leadership council and was asked to speak about Oracle Cloud Infrastructure security. I’ve said that I’m definitely not an expert on security and that’s why the subject was actually a cool one to speak about! If you’ve used any of the major cloud providers (Azure, AWS, GCP) you know the…
Taking a ride with OCI autoscaling and instance pools
Some time ago Oracle Cloud Infrastructure introduced features around autoscaling and instance pools. This in short means you have an instance pool which uses image from the instance configuration you have defined. Instance pool has minimum number of instances you want to keep running and with autoscaling you can add scaling out or in depending…
Series – Get your database running with Terraform part 10: Summary
My idea on writing this guide was to provide overview what components you need when you create a database in Oracle Cloud Infrastructure. Even thought there are several components once you do it few times you get an understanding what you need and it comes a breeze to create these. Most issues I have seen…
Series – Get your database running with Terraform part 9: Database
At this point I have created everything else apart from the database. For the database we have few options starting if we would like to have Baremetal, Virtual Machine or Exadata. In this demo I’m going to create VM single-node database but I could create it as RAC database as well with two nodes. Similar…
Series – Get your database running with Terraform part 8: Compute
Before creating database I will create jump host on public subnet so we will be able to access our database once it’s created. If I would have connection setup to our corporate network I could access the private subnet directly if my network configuration would allow it. This way I can limit the surface on…
Series – Get your database running with Terraform part 7: Subnets
Now we have everything else setup on the network side apart from subnets. Subnets are continuous IP address blocks which don’t overlap with any other subnet IP address block in your VCN. Things to remember: As time of writing this Oracle has released new functionality regarding subnets, regional subnets. Earlier each subnet was tied in…
Series – Get your database running with Terraform part 6: Security Lists
Before we can create the subnets we still need to create security lists. They will control what ingress and egress traffic will be allowed within subnets. I will create two security lists for this project, one for private subnet and another one for public subnet. Security lists can have have multiple rules in them and…
