Pushing Docker Image to a Private Image Registry#
Many docker scheduler and orchestrator platforms provide an internal private registry.
This means that you do not use the default and public
index.docker.io image registry.
I know that the following platforms let you create an internal registry:
- Openshift: OKD
Setting up a docker registry is beyond the scope of this article
The first thing to do is ensure that the image you have created has been tested and is production ready.
Do you have to know which registry you are building for?
Try and login to your registry to ensure it is setup correctly:
docker login some.docker.host.com Username: foo Password: Login Succeeded
Find the container id and commit it to a new image name
docker commit c16378f943fe my-api
Tag the remote repo for that image
docker tag my-api registry.example.co.za:5000/my-api:0.1
Push the image
docker push registry.example.co.za:5000/my-api:0.1
Check if it worked by doing:
docker image list
It should list both the local and remote versions
