最近编写kubernetes的saltstack状态配置文件,在github上找到一个开源的salt文件,根据自己的需要,完成修改之后.执行部署测试 大致目录结构如下: |----k8s | |____node.sls | |____master.sls | |____etcd.sls | |____modules | | |____kubelet.sls | | |____docker.sls | | |____quagga.sls | | |____kube-proxy.sls | | |_…
转自:https://segmentfault.com/a/1190000000513137 今天在进行 saltstack 多环境的时候,遇到一个问题,最终得到解决,好记性不如烂笔头,记录. 首先,我在 salt master 服务器上对 /etc/salt/master 配置文件进行多环境配置,配置文件如下: file_roots: base: - /srv/salt/base dev: - /srv/salt/dev prod: - /srv/salt/prod test: - /srv/…
SLS(代表SaLt State文件)是Salt State系统的核心.SLS描述了系统的目标状态,由格式简单的数据构成.这经常被称作配置管理 首先,在master上面定义salt的主目录,默认是在/srv/salt/下面,vim /etc/salt/master: file_roots: base: - /srv/salt dev: - /srv/salt-dev 然后,在/srv/salt下面创建top.sls文件(如果有的话,就不用创建了,直接编辑好了) vim top.sls base:…

salt 安装 - 传输文件  一.master  -- minion linux 下 master 拷贝到 minion 上 1.cp.get_file 拷贝文件 # salt '172.16.3.15' cp.get_file salt://dev/data/zabbix_agentd_install.sh /home/shell/zabbix_agent_install.sh 2.cp.get_dir 是实现从master端复制目录到minion服务器的对应目录 # salt '172.1…
        众所周知,flink是有状态的计算.所以学习flink不可不知状态.         正好最近公司有个需求,要用到flink的状态计算,需求是这样的,收集数据库新增的数据.         听起来很简单对吧?起初我也这么认为,现在发现,这尼玛就是变相的动态读取啊. 因为数据是一直在增加的,你需要记录这次收集的结果,用于下一次的运算,所以要用到状态计算. 废话不多说,直接上干货. 关于什么是有状态的flink计算,官方给出的回答是这样的:在flink程序内部存储计算产生的中间结果,…
Recently, I am learning Working with ADT. Got some extra thought about State Monad. Basiclly how to thinking in State. First, we need to know the type of State: State returns Pair with Unit on the left, and state on the right: State(state => Pair(Uni…
Not only will we need to give our initial state to a Redux store, we will also need to be able to reset our state at any time by dispatching an action. We can get the best of both worlds by having a function that will return an object with all of our…
Stateful computations require the ability for their state to change overtime. We take a look on one way to replace the state portion of our stateful datatype with a value. We explore the mechanics of how this can be accomplished and introduce the put…
While sometimes outside input can have influence on how a given stateful transaction transitions, there are many times where the current state at the time of a transaction. We can see the power of this type of transaction by seeing what it would take…
