Configure a Booster for Installation
If you have trouble downloading images from dockerhub.io
, it is highly recommended that you configure a registry mirror (i.e. booster) beforehand to speed up downloads. You can refer to the official documentation of Docker or follow the steps below.
Get a Booster URL
To configure the booster, you need a registry mirror address. See how you can get a booster URL from Alibaba Cloud.
Set the Registry Mirror
You can configure the Docker daemon directly or use KubeKey to set the configuration.
Configure the Docker daemon
Note
Run the following commands:
sudo mkdir -p /etc/docker
sudo vi /etc/docker/daemon.json
Add the
registry-mirrors
key and value to the file.{ "registry-mirrors": ["https://<my-docker-mirror-host>"] }
Note
Make sure you replace the address within the quotation mark above with your own Booster URL.Save the file and reload Docker by executing the following commands so that the change can take effect.
sudo systemctl daemon-reload
sudo systemctl restart docker
Use KubeKey to set the registry mirror
After you create a
config-sample.yaml
file with KubeKey before installation, navigate toregistry
in the file.registry: registryMirrors: [] insecureRegistries: [] privateRegistry: ""
Note
For more information about each parameter under theregistry
section, see Kubernetes Cluster Configurations.Provide the registry mirror address as the value of
registryMirrors
and save the file. For more information about installation, see Multi-node Installation.
Note
config-sample.yaml
file is not needed for this mode.Feedback
