===================================================
Set up a Public Repository in Local Docker Registry
===================================================
There will likely be scenarios where you need to make images publicly available
to all users.
.. rubric:: |context|
The suggested method to do that is to create a
keystone tenant/user = 'registry'/'public', which will therefore have access to
images in the registry.local:9001/public/ repository. Then share access to
those images by sharing the registry/public user's credentials with other users.
.. rubric:: |proc|
#. Create the keystone tenant/user of registry/public.
.. code-block:: none
~(keystone_admin)]$ openstack project create registry
~(keystone_admin)]$ TENANTNAME="registry"
~(keystone_admin)]$ TENANTID=`openstack project list | grep ${TENANTNAME} | awk '{print $2}'`
~(keystone_admin)]$ USERNAME="public"
~(keystone_admin)]$ USERPASSWORD="${USERNAME}K8*"
~(keystone_admin)]$ openstack user create --password ${USERPASSWORD} --project ${TENANTID} ${USERNAME}
~(keystone_admin)]$ openstack role add --project ${TENANTNAME} --user ${USERNAME} _member
#. Create a secret containing the credentials of the public repository in
kube-system namespace.
.. code-block:: none
% kubectl create secret docker-registry registry-local-public-key --docker-server=registry.local:9001 --docker-username=public --docker-password=public --docker-email=noreply@windriver.com -n kube-system
#. Share the credentials of the public repository with other namespaces.
Copy the secret to the other namespace and add it as an ImagePullSecret to
the namespace's **default** serviceAccount.
.. code-block:: none
% kubectl get secret registry-local-public-key -n kube-system -o yaml | grep -v '^\s*namespace:\s' | kubectl apply --namespace=<USERNAMESPACE> -f -
% kubectl patch serviceaccount default -p "{\"imagePullSecrets\": [{\"name\": \"registry-local-public-key\"}]}" -n <USERNAMESPACE>
