minikube部署 使用本地self-signed registry

1. host machine

Add `127.0.0.1  docker-registry.local` to /etc/hosts

2. 生成ca文件

#https://docs.docker.com/registry/insecure/

# common name: docker-registry.local

openssl req \
  -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \
  -x509 -days 365 -out certs/domain.crt

3. 启动self-signed registry

docker run -d \
  --restart=always \
  --name registry \
  -v "$(pwd)"/certs:/certs \
  -e REGISTRY_HTTP_ADDR=0.0.0.0:443 \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
  -p 5000:443 \
  registry:2

4. 启动并拷贝ca文件到minikube

minikube start --vm-driver kvm2

scp -i $(minikube ssh-key) certs/domain.crt docker@$(minikube ip):/home/docker

5. 添加该registry到minikube的docker deamon中并重启

minikube ssh << EOF

echo "${host_ip} docker-registry.local" | sudo tee --append /etc/hosts

sudo mkdir -p /etc/docker/certs.d/docker-registry.local:5000

sudo cp /home/docker/domain.crt /etc/docker/certs.d/docker-registry.local:5000/ca.crt

# 重启docker deamon
sudo systemctl restart docker

# 测试是否添加成功
curl -X GET https://docker-registry.local:5000/v2/_catalog --cacert /etc/docker/certs.d/docker-registry.local\:5000/ca.crt

exit

EOF
