A simple script to generation of certificates, kubernetes config files, systemd files and kubernetes binarey file, etc. required for binary deployment of kubernetes clusters.
- Fixed Bug: Malformed path
- Aug 6, 2022: Add Feature: Automatically generate RPM packages
- Mar 31, 2023: Support debian/ubuntu and automatically generate deb package.
- May 26, 2023: Fixed Centos generation RPM package issue.
- Nov 24, 2024:
- Add deb hook scripts (permission and pre-create 'kube' user)
- Improvement function
- Fixed deb systemd unit files for kubernetes service.s
- If you cluster ip is other, you must edit script, to change
generate_openssl_config_filefunction's openssl config setting.
bash <(curl -s https://raw.githubusercontent.com/cylonchau/kubernetes-generator/main/generator.sh)
Must update your kubernetes cluster ip or etcd cluster ip input to bash script after execute bash script
For example
In generator.sh change following
# change your etcd cluster ip and domain [ etcd_server_and_peer_dns ] DNS.1 = \${ENV::BASE_DOMAIN} DNS.2 = localhost IP.1 = 127.0.0.1 IP.2 = 127.0.0.5 # custom define IP.3 = 10.0.0.3 IP.4 = 10.0.0.4 IP.5 = 10.0.0.5 # change your kubernetes apiserver cert ip and domain [ apiserver_names ] DNS.1 = \${ENV::CLUSTER_NAME}-\${ENV::BASE_DOMAIN} DNS.2 = \${ENV::BASE_DOMAIN} DNS.3 = kubernetes DNS.4 = kubernetes.default DNS.5 = kubernetes.default.svc DNS.6 = kubernetes.default.svc.cluster.local IP.1 = \${ENV::KUBEAPISERVER_CLUSTER_IP} # custom define IP.2 = 10.0.0.4 IP.3 = 10.0.0.5 IP.4 = 10.0.0.6 # change your kubernetes master cpmponent cert ip and domain [ master_component_names ] DNS.1 = \${ENV::K8S_MASTER_NAME}.\${ENV::BASE_DOMAIN} DNS.2 = \${ENV::BASE_DOMAIN} IP.1 = 127.0.0.1 # custom define IP.2 = 10.0.0.4 IP.3 = 10.0.0.5 IP.4 = 10.0.0.6 # change your etcd cluster ip and domain used for etcd client # used for etcd_client [ etcd_client ] DNS.1 = localhost IP.1 = 127.0.0.1 # custom define IP.2 = 10.0.0.5 IP.3 = 10.0.0.4 IP.4 = 10.0.0.6 # Don't need change following configuration # used for kubelet kube-proxy [ kube_node ] DNS.1 = \${ENV::CLUSTER_NAME}-\${ENV::BASE_DOMAIN} DNS.2 = \${ENV::BASE_DOMAIN} IP.1 = \${ENV::KUBEAPISERVER_CLUSTER_IP}
- certificate files
- output-generate/certs/etcd, you can copy pki to /etc/etcd/
- output-generate/certs/kubernetes, you can copy to /etc/kubernetes/
- rsyslog config file, copy to /etc/rsyslog.d/, don't forget restart service rsyslog
- output-generate/rsyslog/kubernetes.conf
- systemd files, copy to /usr/lib/systemd/system/
- output-generate/system
- binary files, kubernetes binary file
- output-generate/bin
- auth files, don't forget update kubernetes cluster ip to available ip
- output-generate/kubernetes/master,kubelet/auth
