# If your registry equires user authentication, a file in dockerconfigjson(kubernetes secret type) format needs to be mounted into container /etc/secret/dockerconfigjson
# In the docker run scenario, the content of dockerconfigjson in kubernetes secret needs to be base64 decoded, and then stored it into the ~/dockerconfigjson file
# How to generate dockerconfigjson, please refer to the section "Run in kubernetes"

# Generate secret config file if you need.
# The dockerconfigjson content can be generated by the following command：
kubectl create secret docker-registry my-registry-secret --docker-server=DOCKER_REGISTRY_SERVER --docker-username=DOCKER_USER --docker-password=DOCKER_PASSWORD --docker-email=DOCKER_EMAIL

# Please modify the --storage-registry-repo and --storage-registry-scheme parameters before apply
