方法一
输出docker image镜像标签给IMAGE_TAG
bash
def IMAGE_TAG = sh(script: '''docker images | grep ${SERVER_NAME} | grep $NAME_SPACE | awk '{print $2}'|grep ${BUILD_NUMBER}''', returnStdout: true)
另外,如果想输出docker image命令执行结果给IMAGE_TAG
bash
def IMAGE_TAG = sh(script: '''docker images | grep ${SERVER_NAME} | grep $NAME_SPACE | awk '{print $2}'|grep ${BUILD_NUMBER}''', returnStatus: true)
方法二
其实就是拆分上面的语句
先使用shell把执行后的结果赋值到一个文本,然后读取文本内容赋值给IMAGE_TAG
bash
sh '''docker images | grep ${SERVER_NAME} | grep $NAME_SPACE | awk '{print $2}'|grep ${BUILD_NUMBER} > image.txt'''
def IMAGE_TAG = readFile('image.txt').trim()
