Satellite-6.3-Capsule-as-Docker

### To configure Satellite as Docker Repository, it will be depend on how it's set to published at which URL. But for Capsule will use different URL compare to Satellite. To check correct URL for Capsule, so we can pull docker images from Capsule URL directly, do this :

#Go to Directory /var/lib/pulp/published/docker/v2/web/1-xxx-xxx-xxx (xxx represent random name dir generated by Pulp based on content view configuration)
cd /var/lib/pulp/published/docker/v2/web/1-openshift-cv-dr-7a234-12312-1231-3434-3243-4534-2342398704/tags

#Inside the dir, we can find few files in there, but just simply print the tags list
cat list

# {"name": "abc-dr-openshift-cv-docker-registry-openshift:3_ose-deployer", "tags": "["v3.11.51"... output omitted
#

# Inside the tags, it will show you the complete URL of the images location, something like : capsule.example.com:5000/abc-dr-openshift-cv-docker-registry-openshift:3_image-name:tag, so from client, we can pull image directly with command :

docker pull capsule.example.com:5000/abc-dr-openshift-cv-docker-registry-openshift:3_ose-deployer:v3.11.59
