6.6. Image stream mapping
When the integrated registry receives a new image, it creates and sends an image stream mapping to OpenShift Container Platform, providing the image’s project, name, tag, and image metadata.
注意
Configuring image stream mappings is an advanced feature.
This information is used to create a new image, if it does not already exist, and to tag the image into the image stream. OpenShift Container Platform stores complete metadata about each image, such as commands, entry point, and environment variables. Images in OpenShift Container Platform are immutable and the maximum name length is 63 characters.
The following image stream mapping example results in an image being tagged as test/origin-ruby-sample:latest:
