Container images

The images below are published to registry.kopano.cloud. Access requires a subscription, log in with the credentials you received before pulling. If you lost your credentials, please contact support:

To install a deployment from these images, see run your own Exchange4all deployment. The setup script described there picks the right image and pins it by digest for you, so you only need the tags below when you want to select a version yourself.

Older tags stay available

Only the most recent tags per image are listed here. To list everything you have access to, use the crane CLI:

crane ls registry.kopano.cloud/e4a-container
