Setting up the Environment (One Time Setup)

developer@github: fork repo: git://github/team-org/repoX -> git://github/developer/repoX
developer@workstation: git clone git@github:developer/repoX.git
developer@workstation: git remote add upstream git@github:team-org/repoX.git

Synchronize Fork with Upstream

developer@workstation/master: git pull upstream master

How to execute locally Jenkinsfile

One time setup: Jenkins

Install a local Jenkins (avoid Docker to avoid to have port mapping, volume and other issues)
https://jenkins.io/download/ -> get the war file
Start Jenkins:

wget [jenkins.war]
mkdir jenkins_home
JENKINS_HOME=$PWD/jenkins_home java -jar jenkins.war

When you have a PR which has been here for some times, and master is very active, you will end up have lots of commits in your history when you get the changes from master.

To clean this up:

git fetch origin: get the latest from the repo
git checkout my_branch: go to your branch for pull request
git rebase origin/master: this will rebase the current branch with master
git push -f: force push, as we are rewriting history

Authenticate with ALM and set the LWSSO_COOKIE_KEY cookie

curl -X POST -H "Content-Type: text/xml" --cookie cookies.txt -k --cookie-jar cookies.txt -d "<alm-authentication><user>alm_user</user><password>alm_password</password></alm-authentication>" https://alm_host:8443/qcbin/authentication-point/alm-authenticate

Alternatively (same result):

curl --cookie cookies.txt --cookie-jar cookies.txt --user alm_user:alm_password https://alm_host:8443/qcbin/authentication-point/authenticate

Setup QCSession cookie (need with ALM >= 12.x)

curl -X POST --cookie cookies.txt --cookie-jar cookies.txt https://alm_host:8443/qcbin/rest/site-session

Get defects assigned to an individual

curl --cookie cookies.txt --cookie-jar cookies.txt -g "https://alm_host:8443/qcbin/rest/domains/[ALM_DOMAIN]/projects/[ALM_PROJECT]/defects?fields=id,name,status,severity,owner&query={owner['alm_user']}"

Issue: can't use ssh or git commands when connected on VPN. This is because, for now, outgoing ssh / TCP 22 is blocked.

We have to tunnel through the web proxy. Here is how:

On Windows

Download and install nmap-7.70-setup.exe from https://nmap.org/download.html. We will use ncat tool to send all packets through the proxy.
Open command line (WIN Key+R+cmd+ENTER)
cd %USERPROFILE%\.ssh. This is where you have stored your ssh private key for GitHub
Create a new file named config
Add

If you had to explain the concept of DevOps to a child, what would you say?
How does the interface with product management aid or detract from the flow of work?
How do we start a DevOps transformation?
You are involved in “re-platforming” (lift existing physical hardware to cloud) but leave the software untouched. Can you do DevOps?
What are your favorite sources for learning today, related to DevOps transformations?
How have mainstream stories of security breaches affected the way we and organizations work?
What mechanisms should be in place to challenge pre-existing notions about software delivery in an enterprise?
How do we get people outside of the tech organization to not just participate in the DevOps journey, but be active leaders in it as well?
How do you see DevOps practices being implemented outside of Development and IT Operations?
What obstacles do technology leaders face in large, complex organizations that are outside the technology value stream?

Use case: when I go to specific AWS region, I want the UI to be styled differently (color). Avoids goofing in some places.

Install Stylus chrome extension https://add0n.com/stylus.html
Install this style: https://userstyles.org/styles/150583/aws-navbar-color-by-region

This can be tweaked / modified:

@-moz-document domain(us-east-1.console.aws.amazon.com)
{

Delete offline nodes

for (aSlave in hudson.model.Hudson.instance.slaves) {
    if (aSlave.getComputer().isOffline()) {
        aSlave.getComputer().setTemporarilyOffline(true,null);
        aSlave.getComputer().doDoDelete();
    }
