Public Download Mirror

The public mirror is useful to make the public resources download quickly in some areas of the world. (such as China).

Configuring Kubespray to use a mirror site

You can follow the offline to config the image/file download configuration to the public mirror site. If you want to download quickly in China, the configuration can be like:

gcr_image_repo: "gcr.m.daocloud.io"
kube_image_repo: "k8s.m.daocloud.io"
docker_image_repo: "docker.m.daocloud.io"
quay_image_repo: "quay.m.daocloud.io"
github_image_repo: "ghcr.m.daocloud.io"

files_repo: "https://files.m.daocloud.io"

Use mirror sites only if you trust the provider. The Kubespray team cannot verify their reliability or security. You can replace the m.daocloud.io with any site you want.

Example Usage Full Steps

You can follow the full steps to use the kubesray with mirror. for example:

Install Ansible according to Ansible installation guide then run the following steps:

# Copy ``inventory/sample`` as ``inventory/mycluster``
cp -rfp inventory/sample inventory/mycluster

# Update Ansible inventory file with inventory builder
declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
CONFIG_FILE=inventory/mycluster/hosts.yaml python3 contrib/inventory_builder/inventory.py ${IPS[@]}

# Use the download mirror
cp inventory/mycluster/group_vars/all/offline.yml inventory/mycluster/group_vars/all/mirror.yml
sed -i -E '/# .*\{\{ files_repo/s/^# //g' inventory/mycluster/group_vars/all/mirror.yml
tee -a inventory/mycluster/group_vars/all/mirror.yml <<EOF
gcr_image_repo: "gcr.m.daocloud.io"
kube_image_repo: "k8s.m.daocloud.io"
docker_image_repo: "docker.m.daocloud.io"
quay_image_repo: "quay.m.daocloud.io"
github_image_repo: "ghcr.m.daocloud.io"
files_repo: "https://files.m.daocloud.io"
EOF

# Review and change parameters under ``inventory/mycluster/group_vars``
cat inventory/mycluster/group_vars/all/all.yml
cat inventory/mycluster/group_vars/k8s_cluster/k8s-cluster.yml

# Deploy Kubespray with Ansible Playbook - run the playbook as root
# The option `--become` is required, as for example writing SSL keys in /etc/,
# installing packages and interacting with various systemd daemons.
# Without --become the playbook will fail to run!
ansible-playbook -i inventory/mycluster/hosts.yaml  --become --become-user=root cluster.yml

The above steps are by adding the "Use the download mirror" step to the README.md steps.
