Setting up a Python Virtual Environment on VS code

The best practice among python development is to use project specific virtual environment so that you can install any packages in isolation from other environments- this reduces any complications that can arise from conflicting package versions.

On VS code use the command palette (shift+ command +P), then type Python: Create Environment, select Venv

Installing OCI CLI on Mac OS

Update:

First install Homebrew if your Mac doesn’t have it installed:

  • Install Homebrew using the command from Homebrew’s official website:

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

    Enter your Mac login password if prompted. Terminal won’t display characters while you type it.

  • When installation finishes, run the commands it prints under “Next steps”. These add Homebrew to your PATH.

Command Line Interface (CLI) provides the same core functionality as the console, plus additional commands, like the ability to run scripts which extends the console functionality.

To install CLI, you must have

  • OCI cloud account
  • User in a group with the right permissions
  • A key pair used for signing API requests- public key uploaded at Oracle cloud

To install the CLI on Mac OS with HomeBrew:

brew update && brew install oci-cli

To verify the OCI CLI installation

oci --version

To set up the configuration File- there are two ways to do it;

a) Use the set up config Dialog

oci setup config

this command prompts with the information required to create the configuration file and API keys. After the set up, you should upload the public api key on your the API keys section of your profile on OCI.

b) Manual set up

Log into your Oracle cloud, go to your profile, -> API keys & add an API key

Add an API Key in PEM format or generate an API key pair

Download the private key & save config file details – You will use them to set up the config file.

On your MAC OS, navigate to the .oci folder.

cd ~/.oci

if you don’t have the .oci folder, make the directory

mkdir ~/.oci

Paste the private key downloaded from OCI on this folder and edit the permissions to ensure that only you can read the private key file:

 chmod go-rwx ~/.oci/<oci_api_key_name.pem

Create a config file and paste the config file details from OCI.

vi config

The config file content looks similar to this- add yours,

[DEFAULT]
user=ocid1.user.oc1..<unique_ID>
fingerprint=<your_fingerprint>
key_file=~/.oci/oci_api_key.pem
tenancy=ocid1.tenancy.oc1..<unique_ID>
region=uk-london-1

(To exit vi, press escape, :wq!)

All done! Test if the OCI CLI is correctly installed and working;

oci os ns get

You should be able to read, create, update, delete the OCI resources. The output from the above command should be the Tenancy name of your OCI cloud.

{
  "data": "<tenancyname>"
}

To create an OCI object storage bucket using OCI CLI example

oci os bucket create --compartment-id <Compartment OCID> --name TestCLI

 

Add a file on Object Storage using the pipe command

echo "Hello World" | oci os object put --bucket-name my-bucket --name file.txt --file -

Delete Objects in a bucket (Use –dry-run at the end if you want to first preview)

oci os object bulk-delete --namespace-name <object_storage_namespace> --bucket-name <bucket_name>

Other useful cmds;

To upgrade your CLI install on Mac OS using Homebrew:

brew update && brew upgrade oci-cli

To uninstall the CLI on Mac OS using Homebrew:

brew uninstall oci-cli

Creating OCI CLI profile

oci setup config --profile myprofile

To use the profile, specify the name on the –profile section

oci os ns get --profile myprofile

To generate new public and private keys on the .oci folder

openssl rsa -pubout -in ~/.oci/oci_api_key.pem -out ~/.oci/oci_api_key_public.pem
