這篇文章將為大家詳細(xì)講解有關(guān)如何通過puppet管理遠(yuǎn)程docker容器并配置puppet和實(shí)現(xiàn)變更，小編覺得挺實(shí)用的，因此分享給大家做個(gè)參考，希望大家閱讀完這篇文章后可以有所收獲。

前提準(zhǔn)備：
1.master和docker節(jié)點(diǎn)上分別安裝好puppet master和puppet agent；
2.docker節(jié)點(diǎn)上安裝好docker1.2.0、nsenter（被腳本用于連接容器），并pull一個(gè)鏡像：training/webapp
master上的準(zhǔn)備工作：
創(chuàng)建docker模塊：

done編輯/etc/puppet/manifests/nodes/docker.hzg.com.pp,加載docker類：
node 'docker.hzg.com' {
include docker
}編輯/etc/puppet/manifests/site.pp,加載docker節(jié)點(diǎn)的配置，增加這么一行：
import "nodes/docker.hzg.com.pp"
編輯/etc/puppet/fileserver.conf，授權(quán)docker對(duì)modules和files的訪問，添加內(nèi)容：
[files] path /etc/puppet/files allow docker.hzg.com # allow *.example.com # deny *.evil.example.com # allow 192.168.0.0/24 [files] path /etc/puppet/modules allow *.hzg.com
編輯/etc/puppet/puppet.conf，在[main]那一段增加以下內(nèi)容（可選）：
modulepath = /etc/puppet/modules
PS：因?yàn)槲沂褂胮uppet kick實(shí)現(xiàn)配置，要為agent做點(diǎn)配置工作：
agent上：
編輯puppet.conf，在[agent]那段增加以下內(nèi)容（可選）：
listen = true
實(shí)現(xiàn)配置：
master上：
root@workgroup:~# puppet kick docker.hzg.com Warning: Puppet kick is deprecated. See http://links.puppetlabs.com/puppet-kick-deprecation Warning: Failed to load ruby LDAP library. LDAP functionality will not be available Triggering docker.hzg.com Getting status status is success docker.hzg.com finished with exit code 0 Finished
因?yàn)槲覜]有配置LDAP，所以有些警告內(nèi)容。
檢查docker節(jié)點(diǎn)上的信息：
root@docker:~# ls BACKUPDockerfile control.sh Dockerfile hzg.sh init.pp status.log test2.sh test.py util-linux-2.24 root@docker:~# cd /var/log/dockerlaunch/ root@docker:/var/log/dockerlaunch# ls web1.log webbase.log root@docker:/var/log/dockerlaunch# cd ~ root@docker:~# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 050ebb07cf25 training/webapp:latest "python app.py" About a minute ago Up About a minute 0.0.0.0:2000->5000/tcp web1 0ef5d56e4c89 training/webapp:latest "python app.py" About a minute ago Up About a minute 0.0.0.0:1000->5000/tcp web1/webbase,webbase
