Environment

standard

example 1: sample

pipeline{
	agent{
	    label "k8s-permanent"
	}
	environment{
	    name1 = "nim1"
	    name2 = "nim2"
	}
	stages{
		stage("Build"){
		    environment{
        	    name3 = "nim3"
        	}
			steps{
				echo "name1 ${name1}"
				echo "name2 ${name2}"
				echo "name3 ${name3}"
			}
		}
	}
}

example 2: environment didn’t declared in stage Pipeline

pipeline{
	agent{
	    label "k8s-permanent"
	}
	environment{
	    name1 = "nim1"
	    name2 = "nim2"
	}
	stages{
		stage("Build"){
		    environment{
        	    name3 = "nim3"
        	}
			steps{
				echo "name1 ${name1}"
				echo "name2 ${name2}"
				echo "name3 ${name3}"
			}
		}
		
		stage("Test"){
			steps{
				echo "name1 ${name1}"
				echo "name2 ${name2}"
				echo "name3 ${name3}"
			}
		}
	}
}

Example 3: environment declared at both global and stage Pipeline

pipeline{
	agent{
	    label "k8s-permanent"
	}
	environment{
	    name1 = "nim1"
	    name2 = "nim2"
	}
	stages{
		stage("Build"){
		    environment{
		        name2 = "change_nim2"
        	    name3 = "nim3"
        	}
			steps{
				echo "name1 ${name1}"
				echo "name2 ${name2}"
				echo "name3 ${name3}"
			}
		}
	}
}

example 4: print env of system

pipeline{
	agent{
	    label "k8s-permanent"
	}
	environment{
	    name1 = "nim1"
	    name2 = "nim2"
	}
	stages{
		stage("Build"){
		    environment{
		        name2 = "change_nim2"
        	    name3 = "nim3"
        	}
			steps{
				echo "name1 ${name1}"
				echo "name2 ${name2}"
				echo "name3 ${name3}"
				sh "printenv"
			}
		}
	}
}

credential

vì ID lúc tạo được để trống nên tự gen ID

pipeline{
	agent{
	    label "k8s-permanent"
	}
	environment{
	    user_pass = credentials("e375d6c5-54b2-4881-996e-58430673a8f4")
	    text_secret = credentials("ad2def08-0d61-4503-a6d5-a98666d730fd")
	}
	stages{
		stage("Build"){
			steps{
				echo "user_pass ${user_pass}"
				echo "user_pass ${user_pass_USR}" // prefix _USR lấy username
				echo "user_pass ${user_pass_PSW}" // prefix _PSW lấy passwork
				echo "user_pass ${text_secret}"
			}
		}
	}
}
