Jenkins 流水线语法 05 构建时变量 environment

env 构建时变量

之前讲的是全局变量，现在是构建时候自己定义所运行的一些变量

定义：通过键值对（k-v）格式定义流水线在运行时的环境变量， 分为流水线级别和阶段级别。(可以使用enviorment语句块里面去写我们的变量，不需要加逗号分割，每行就是一个变量)

流水线级别环境变量参考：(全局变量，在pipeline下面定义的语句块，在这里面的变量在下面所有的阶段都可以去使用)

pipeline { environment { NAME = "zeyang" VERSION = "1.1.10" ENVTYPE = "DEV" }}

阶段级别环境变量参考：（局部变量，在某个阶段里面定义的变量，那么只能在某个阶段去使用）

pipeline { ... ... stages { stage("build"){ environment { VERSION = "1.1.20" } steps { script { echo "${VERSION}" } } } }}

全局变量

pipeline { agent any environment{ VERSION = "1.1.1" ENV_TYPE = "DEV" } stages { stage('Hello') { steps { script{ echo "The variable version is ${VERSION}" echo "The variable env_type is ${ENV_TYPE}" } } } }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on Jenkins in /var/jenkins_home/workspace/pipeline-test[Pipeline] {[Pipeline] withEnv[Pipeline] {[Pipeline] stage[Pipeline] { (Hello)[Pipeline] script[Pipeline] {[Pipeline] echoThe variable version is 1.1.1[Pipeline] echoThe variable env_type is DEV[Pipeline] }[Pipeline] // script[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // withEnv[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineFinished: SUCCESS

这里是在stage里面定义了变量，也就是局部变量

pipeline { agent any environment{ VERSION = "1.1.1" ENV_TYPE = "DEV" } stages { stage('Hello') { environment{ VERSION="1.0.0" } steps { script{ echo "The variable version is ${VERSION}" echo "The variable env_type is ${ENV_TYPE}" } } } }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on Jenkins in /var/jenkins_home/workspace/pipeline-test[Pipeline] {[Pipeline] withEnv[Pipeline] {[Pipeline] stage[Pipeline] { (Hello)[Pipeline] withEnv[Pipeline] {[Pipeline] script[Pipeline] {[Pipeline] echoThe variable version is 1.0.0[Pipeline] echoThe variable env_type is DEV[Pipeline] }[Pipeline] // script[Pipeline] }[Pipeline] // withEnv[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // withEnv[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineFinished: SUCCESS

全局变量（env.JOB_NAME 这个是jenkins内置的全局变量，env.是自定义的全局环境变量，注意不要覆盖了Jenkins内置的全局变量）

pipeline { agent any environment{ VERSION = "1.1.1" ENV_TYPE = "DEV" } stages { stage('Hello') { environment{ VERSION="1.0.0" } steps { script{ echo "The variable version is ${VERSION}" echo "The variable env_type is ${ENV_TYPE}" echo "The job name is ${env.JOB_NAME}" //内置的环境变量 env.JOB_NAMEA="mytest-pipeline" //自定义的全局变量,也就是整个流水线可以去使用 echo "the variable env.JOB_NAMEA is ${env.JOB_NAMEA}" } } } }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on Jenkins in /var/jenkins_home/workspace/pipeline-test[Pipeline] {[Pipeline] withEnv[Pipeline] {[Pipeline] stage (hide)[Pipeline] { (Hello)[Pipeline] withEnv[Pipeline] {[Pipeline] script[Pipeline] {[Pipeline] echoThe variable version is 1.0.0[Pipeline] echoThe variable env_type is DEV[Pipeline] echoThe job name is pipeline-test[Pipeline] echothe variable env.JOB_NAMEA is mytest-pipeline[Pipeline] }[Pipeline] // script[Pipeline] }[Pipeline] // withEnv[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // withEnv[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineFinished: SUCCESS
