Repository credentials
Overview
Docker credentials for edge computing are like keys to a locked box holding your online Docker images. It's similar to having a library card for a private library – without it, you can't access your important code images stored there. It contains essential information such as authentication details (like repository URL, usernames and passwords) required to securely pull Docker images from your private repositories. This card helps maintain security and streamline deployment processes, making it easier to manage software updates and configurations in distributed computing environments.

After adding a credential, the node checks if it is valid trying to login using the data (URL, user, password, etc). The status of the credentials reflects its validity. Your status will be indicated in each credential tab by either a green tick or a red cross.

You can also check the status of all your Credentials at the top of your Card. There will be a short summary of all your added Credentials and an indication on how many are “OK”. If there is an error with any of your Credentials this will be indicated by a red “Warning” icon (highlighted in red).
