Interacting with OCI Object Storage using Go SDK (first steps)

I’m still fairly new at working with Go. I have the goal of working with, and perhaps even on, several open source projects that use Go as their implementation language. It seems like the number of open source projects using Go is increasing rapidly. It also seems like I need to get acquainted more with Go, and find out how to interact from Go with Oracle Cloud Infrastructure (OCI), as I intend to add features to open source products that leverage OCI services.

Go application for interacting with the OCI ObjectStorage Service

In this article we’ll get a quick introduction to interactions with the OCI Object Storage Service for the purpose of creating and removing a bucket, and an object in that object from a simple Go program that uses the OCI Go SDK. My environment is Ubuntu 20.4 on WSL2 on Windows 10, although that shouldn’t matter much.

The steps in this article:

• Install a Go environment.
• Create a Go application to connect to OCI using the OCI SDK.
• Interact with OCI Object Storage.

Install Go

Using this article: Install Go on Ubuntu — https://buildvirtual.net/how-to-upgrade-go-on-ubuntu/ — I quickly got the current version of Go removed and the latest version of Go installed.

Go get the URL for the latest release: https://go.dev/dl/

Download site for Go binaries

Download using wget and untar

Then move the extracted directory go to the /usr/local directory:

I tried to run go at this point, but I was too early. First, a small edit of .profile is in order: add the definition of environment variable GOPATH and add $GOPATH to the PATH environment variable.

Once the change is made to .profile and the change has been applied with source ~/, the profile environment is once again ready to run Go with the latest version.
