To push a new Docker container image to a repository in OCI Registry, you need to use an Auth Token to complete the authentication via the Docker CLI1. An Auth Token is a secure, auto-generated password that you can use to authenticate with OCI services such as OCI Registry1. You can generate an Auth Token in the Console by following these steps1:

• In the top-right corner of the Console, open the Profile menu and then click User settings to view the details.
• On the Auth Tokens page, click Generate Token.
• Enter a friendly description for the auth token. Avoid entering confidential information.
• Click Generate Token. The new auth token is displayed.
• Copy the auth token immediately to a secure location from where you can retrieve it later, because you won’t see the auth token again in the Console.
• Close the Generate Token dialog. After generating an Auth Token, you need to log in to OCI Registry by entering docker login .ocir.io in a terminal window on the client machine running Docker, where corresponds to the key for the OCI Registry region you’re using1. When prompted for a username, enter your username in the format /, where is the auto-generated Object Storage namespace string of your tenancy1. When prompted for a password, enter the Auth Token you copied earlier1.

Explanation

The term that describes developing microservices in different languages of choice is "Polyglot." In a polyglot architecture, each microservice is developed using the most appropriate programming language or technology stack for its specific requirements. This approach allows developers to leverage the strengths of different languages and frameworks, enabling them to use the most suitable tool for each microservice while still maintaining interoperability between services.
