Hosting a docker image on the Central Artefact Repository¶
As part of our goal to align all developmental efforts to one standard, we have documented a procedure of how we would like all the SKA developers to version tag their docker images and what process to follow in ensuring that they are able to make use of the existing Gitlab CI/CD pipeline to automate the building of docker images, for now, and have them published on the SKA docker registry which is hosted on Central Artefact Repository.
Tagging the docker image¶
To explicitly tag a docker image run the following command:
$ docker tag <source_image> artefact.skao.int/<repository_name>/<image_name>:<tag_name>
This command will create an alias by the name of the
<image_name> that refers to the
Note that naming and tagging conventions are outlined in the containerisation standards. And those should follow the same semantic versioning used for the repository.
Uploading the docker image to the Central Artefact Repository¶
Once the docker image has been built and tagged, it can then be uploaded to the Central Artefact Repository registry by executing the following command:
$ docker push artefact.skao.int/<repository_name>/<image_name>:<tag_name>
