Jenkins exposes the current status of your build as an icon in a fixed URL. You can put this URL into other sites (such as GitHub README) so that people can see the current state of the build.
Now you have Jenkins installed, If you have a Jenkinsfile try to run stage in a dedicated docker container instance, You have two options to resolve the dependency to docker.
pipeline {
// agent any
stages {
stage('Spell Check') {
agent {
dockerfile {
filename 'Dockerfile.mdspell'
args '-u="root"'
}
}
}
}
}
For my case, I have Jenkins running as a Docker container in an Azure Ubuntu Linux VM， so in the VM host I already have Docker installed. But within the container of Jenkins, the docker is not installed.
So I specify another VM host with Docker installed as a slave agent node to the Jenkins Master host (192.168.1.1:8080). The Jenkins Master will assign pipeline jobs to the slave agent node to run.
Configure as below and Save.
Notes: during my setting up, the log remind me to install Java in the slave agent node.
sudo apt install openjdk-8-jdk
Step 1: 假设Jenkins所在服务器的地址是：192.168.0.1，端口为8080，那么webhook地址就是 http://192.168.0.1:8080/github-webhook/
Step 2: GitHub -> Settings -> Webhooks -> Add webhook and fill Payload URL with the webhook address in step 1.
Make sure the port of the Jenkins Server allow the inbound from GitHub. If the Jenkins Server is hosted in Azure VM, define an inbound port rule to allow traffic from GitHub Server.
当Jenkins 接收到来之GitHub的webhook 的通知后，Jenkins需要访问GitHub repository的时候，有的操作是需要授权的，所以我们要在GitHub上生成授权的token给Jenkins使用，这就是Personal access tokens.
Fill “API URL” with https://api.github.com, “Credentials” Choose “Add”
In The pop up form，”Kind” Choose ”Secret text”，”Secret”填入前面在GitHub上生成的Personal access tokens.
Google’s on-call practice:
The responsibilities of on-call engineers:
The major problems of our work are not so much technological as sociological in nature.
The high tech illusion
The researchers who made fundamental breakthroughs in those areas are in a high-tech business. The rest of us are appliers of their work.
We use computers and other new technology components to develop our products or to organize our affairs. We are mostly in the human communication business.
Our successes come from good human interactions.
We have to learn to do work less of the time and think about the work more.
我们必须学会花更少的时间工作和花更多的时间思考工作本身。
Quality, far beyond that required by the end user, is a means to higher productivity.
远远超过超过最终用户需求的质量是取得更高生产力的手段。
Lose weight while sleeping
False Hope: Technology is moving swiftly, that you’re being passed by.
Technology is moving swiftly, but (the High-Tech Illusion again) most of what you’re doing is not truly high-tech work.
That is Management
The manager’s function is not to make people work, but to make it possible for people to work.
In Part II, we’ll look into some of the causes of lost time and propose measures that you can take to create a healthy, work-conducive environment.
If you manage a team of people who need to use their brains during the workday, then the workplace environment (quite,space, and privacy) is your business.
The phenomena of flow and immersion give us a more realistic way to model how time is applied to a development task. What matters is not the amount of time you’re present, but the amount of time that you’re working at full potential. An hour in flow really accomplishes something, but 10 six-minute work periods sandwiched between 11 interruptions won’t accomplish anything.
E-Factor = Uninterrupted Hours/Body-Present Hours
Design Your Workspace
Sit Behind A wall And Make Sure At Least Eight Feet A Wall In Front
As you work, you want to occasionally look up and rest your eyes by focusing on something farther away than the desk.
If there is a blank wall closer than eight feet your eyes will not change focus and they get no relief.
Windows
When you set out to hire a programmer, the rules of common sense are often suspended. You don’t ask to see a design or a program or anything. In fact, the interview is just talk.
Build Your Portfolio and show it off as part of each interview next time.
How to build it then? Put everything as code.
