I’m pleased to share all my cloud posts on this page. As with all the other pages, posts are in chronological order.

Putty-like SSH port forwarding on Linux and MacOS

As a Linux or Mac user you benefit from a very useful, built-in terminal and SSH client implementation that’s mostly identical across all Unix-like systems. The situation used to be different on Windows. Before Windows supported a built-in SSH client on the command line Putty was (and still is!) one of the primary tools available…

Avoid “Warning: Additional provider information from registry” for OCI Terraform Provider

After updating my main development workstation to Fedora 36 including all the tools I regularly use I noticed a change when working with Terraform code. The call to terraform init succeeded but was accompanied by a warning: $ terraform version -no-color Terraform v1.2.3 on linux_amd64 $ terraform init -no-color Initializing the backend… Initializing provider plugins……

Retrieving passwords from OCI Vault for use in Terraform

This post is written with the intention to complement the excellent “A comprehensive guide to managing secrets in your Terraform code” by Yevgeniy Brikman. Its aim is to detail how Oracle Cloud Infrastructure Vault (OCI Vault) can be used to securely store credentials and subsequently use them in Terraform scripts. If you haven’t done so…

Configuring a VM using Ansible via the OCI Bastion Service

In my previous post I wrote about the creation of a Bastion Service using Terraform. As I’m incredibly lazy I prefer to configure the system pointed at by my Bastion Session with a configuration management tool. If you followed my blog for a bit you might suspect that I’ll use Ansible for that purpose. Of…

Create an OCI bastion service via Terraform

Maintaining bastion hosts (a “jump box” or other network entry point directly exposed to the Internet) is somewhat frowned upon by security conscious architects, for good reasons. In my opinion the only way to connect on-premises systems to the cloud is by means of a dedicated, low-latency/high-bandwidth, and most importantly well-secured link. I never liked…

Deploying I/O intensive workloads in the cloud: mdadm (aka Software) RAID

The final part of my “avoiding pitfalls with Linux Logical Volume Manager” (LVM) series considers software RAID on Oracle Linux 8 as the basis for your LVM’s Physical Volume (PV). It’s still the very same VM.Standard.E4.Flex running Oracle 19.12.0 on top of Oracle Linux 8.4 with UEK6 (5.4.17-2102.203.6.el8uek.x86_64) I used for creating the earlier posts.…

Install the Oracle Cloud Infrastructure CLI on Ubuntu 20.04 LTS

This is a short post on how to install/configure the Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI) on Ubuntu 20.04 LTS. On a couple of my machines I noticed the default Python3 interpreter to be 3.8.x, so I’ll stick with this version. I used the Manual installation, users with higher security requirements might want…

Deploying I/O intensive workloads in the cloud: LVM RAID

I recently blogged about a potential pitfall when deploying the Oracle database on LVM (Logical Volume Manager) with its default allocation policy. I promised a few more posts detailing how to potentially mitigate the effect of linear allocation in LVM. The post was written with the same Oracle 19.12.0 database deployed to Oracle Linux 8.4…
