4.安装docker镜像仓库

unzip package
run registry service

5.安装k8s

Install kubeadm/kubelet/kubectl
master init

安装步骤

1.导入所需要的包

Baidu cloud address:

把所有下载的包放入如下目录：
{{ projectname }}/artifacts/

containerd-selinux-v2.119.2.tar
docker-ce-stable-v20.10.7.tar
kubernetes-v1.21.2.tar
registry-1.21.2.tar.gz

2.编写 hosts.ini

[all:vars]
ansible_connection=ssh
ansible_user=zhangsan
ansible_password=9876557
# same as `ansible_ssh_pass`
ansible_become_pass=9876557

[kubernetes:children]
kubernetes_master
kubernetes_master_slaves
kubernetes_slaves

[kubernetes_master_all:children]
kubernetes_master
kubernetes_master_slaves

[kubernetes_master]
172.16.**.***

[kubernetes_master_slaves]

[kubernetes_slaves]
172.16.**.***
172.16.**.***

[docker:children]
kubernetes
registry

[registry]
172.16.**.***

[repo]
172.16.**.***

3.编写 shared.yml

#---------------------------------
## Docker image  repo
##---------------------------------
docker_repo_ip: "172.20.**.***"
docker_repo_address: "***k8s-registry-address***:**port**"
docker_repo_domain_name: "***k8s-registry-address***"

master_ip: "172.20.**.***"
kubernetes_api: "apiserver.*****.local"   
#---------------------------------
###  package  repo
###---------------------------------
#
repo: "172.20.**.***"

4.检查各个role目录下的参数配置是否正确 defult/main.yml file

check eack role's defult/main.yml file ，set parameter

5. 安装

{{projectname}} is project name ,is k8s-ansible/

cd {{projectname}} 
执行如下指令：
ansible-playbook ./playbooks/01_prepare.yml
ansible-playbook ./playbooks/02_yum_repo.yml
ansible-playbook ./playbooks/03_docker_install.yml
ansible-playbook ./playbooks/04_install_docker_register.yml
ansible-playbook ./playbooks/05_install_k8s.yml
ansible-playbook ./playbooks/06_install_ceph.yml

f you want to test whether the configuration file is correct first, as in the above steps, add -C after the instruction, for example:

ansible-playbook ./playbooks/01_prepare.yml -C

6. 问题：

1.When the running is interrupted, you want to repeat it.

2.ceph安装用简单的块设备就可以识别
