ansible-playbook部署docker的方法
一、部署docker方法1、yum2、二进制以二进制批量部署docker二、Playbook配置文件[root@k8s-master2 ~]# mkdir docker-deploy[root@k8s-master2 ~]# cd docker-deploy/[root@k8s-master2 docker-deploy]# ls[root@k8s-master2 docker-deploy]#
一、部署docker方法
1、yum
2、二进制
以二进制批量部署docker
二、Playbook配置文件
[root@k8s-master2 ~]# mkdir docker-deploy
[root@k8s-master2 ~]# cd docker-deploy/
[root@k8s-master2 docker-deploy]# ls
[root@k8s-master2 docker-deploy]# mkdir files
[root@k8s-master2 docker-deploy]# cd files/
root@k8s-master2 files]# ls
docker docker-18.09.6.tgz docker.service
[root@k8s-master2 docker-deploy]# more deploy.yaml
---
- hosts: webservers
vars:
remoter_user: root
gather_facts: false
tasks:
- name: 分发解压包
unarchive: src=/files/docker-18.09.6.tgz dest=/tmp
- name: 移动二进制文件
shell: mv /tmp/docker/* /usr/bin
- name: 分发service文件
copy: src=files/docker.service dest/usr/lib/systemd/system
- name: 启动设置开机启动
systemd: name=docker state=restarted enabled=yes
- name: docker 启动状态
shell: docker info
register: docker
- debug: var=docker.stdout_lines
三、systemd管理服务
[root@k8s-master2 files]# more docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service containerd.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutSec=0
RestartSec=2
Restart=always
StartLimitBurst=3
StartLimitInterval=60s
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
TasksMax=infinity
Delegate=yes
KillMode=process
[Install]
WantedBy=multi-user.target
四、验证节点服务器docker启动
[root@k8s-master2 docker-deploy]# ansible-playbook deploy.yaml
[root@k8s-node2 ~]# docker --version
Docker version 18.09.6, build 481bc77
