CI configuration

All the non related infrastructure configuration is managed by the secrets explained in the previous section The following section contains the configuration needed on the python pipeline to create the infrastructure in the oracle cloud.

The configuration is stored at the pipeline/config.py file.

Compartment

The compartment will be the root of all the resources created for this application. The organization in the cloud infrastructure is divided into compartments to organize resources.

It's created / deleted based on its name in the COMPARTMENT_NAME variable.

Creating a custom compartment allows to isolate the application resources from the rest of the cloud resources we may be using in the account.

On creation/getting it from the existing ones by name, it will use an OCID like this:

ocid1.compartment.oc1..aaaaaaaapmqwjhsyggcyrvqxytrpgsfsqsvsrnnrmpnxmhjukpykajvnjdjj

Virtual CLoud Network (VCN)

The VCN will have all the network related infrastructure used by this application. It will be needed to configure a router table with an Internet Gateway attached, a subnet and a security List.

Security List

The SECURITY_LIST_RULES configuration allows us to configure the opened ports for the instance. We just need HTTP/HTTPS and the provided SSH port.

SECURITY_LIST_RULES = [
{
    "port": 80,
    "description": "HTTP traffic for discord and monitoring connection to the bot"
},
{
    "port": 443,
    "description": "HTTPs traffic for discord and monitoring connection to the bot"
}

]

Instance

The following configuration applies to the instance, the operating system and version will determine the image ocid used to create the instance.

INSTANCE_OPERATING_SYSTEM = "Canonical Ubuntu"
INSTANCE_OPERATING_SYSTEM_VERSION = "20.04"
INSTANCE_SHAPE = "VM.Standard.E2.1.Micro"

Image identifier

The identifier of the image depends on the image, build and region.

The full list of OCIDs for images are listed here It's needed to enter on the Read more section to see the OCIDs for each region

To get it, the most recent not aarch64 image is selected matching the operating system and version configured for the actual region.

Instance shape

This is the shape of the compute instance created. It's a template that will determine the number of CPUs, amount of memory and other resources allocated.

While creating an instance on the web console, it's the name displayed for the selected shape, for example:

VM.Standard.E2.1.Micro
