Set up your own Docker images registry in Bluemix by defining a namespace for your organization (corresponding IBM Containers command: cf ic namespace set <namespace>). The namespace is used to generate a unique URL to your private Bluemix registry. In your private registry you store all Docker images that you want to share across your organization. To create a container from an image, you must first push the image to your registry.
The namespace cannot be changed after is has been set. Consider the following rules to choose a namespace for your organization:
- Every organization can have one namespace at a time only
- The namespace must be unique in Bluemix.
- The namespace can be 4-30 characters long.
- The namespace must start with at least one letter or number.
- The namespace can only contain lowercase letters, numbers or underscores (_).
