GitHub Actions: Deploying a containerized application connected to NoSQL

[dario-vega]

In this discussion, we are showing how easy is to deploy a containerized application using NoSQL and GitHub actions.

• Use the run-oci-cli-command GitHub Action to create your NoSQL table directly from GitHub.

This GitHub Action installs the OCI CLI and then runs the specified command. This action will automatically cache the OCI CLI install to speed up any subsequent steps that use this action.

• Use the configure-kubectl-oke GitHub Action to deploy your application to a Kubernetes cluster using kubectl.

Use this GitHub Action to install and configure kubectl to connect to the specified Oracle Container Engine for Kubernetes (OKE) cluster.

And here is an example of an Action Workflow used during our demos

Note: even if you can create your OCI NoSQL Table directly from your application, we recommend separating both tasks.
