示例
http://fishi.devtail.io/weblog/2016/11/20/ docker-build-pipeline-as-code-jenkins /
stage ('Docker Build') {
// prepare docker build context
sh "cp target/project.war ./tmp-docker-build-context"
// Build and push image with Jenkins' docker-plugin
withDockerServer([uri: "tcp://<my-docker-socket>"]) {
withDockerRegistry([credentialsId: 'docker-registry-credentials', url: "https://<my-docker-registry>/"]) {
// we give the image the same version as the .war package
def image = docker.build("<myDockerRegistry>/<myDockerProjectRepo>:${branchVersion}", "--build-arg PACKAGE_VERSION=${branchVersion} ./tmp-docker-build-context")
image.push()
}
}
}
结果：
WorkflowScript: 5: Unknown stage section "sh". Starting with version 0.5, steps in a stage must be in a steps block. @ line 5, column 1.
stage ('Docker Build') {

尝试解决问题
添加步骤块后，管道再次失败：
WorkflowScript: 13: Method calls on objects not allowed outside "script" blocks. @ line 13, column 13.
docker.withRegistry
#1 楼
您可以尝试在声明式管道中使用脚本语法。对于某些步骤，尚无声明性语法。我在尝试使用docker全局变量作为步骤时遇到了相同的问题。stage ('Docker Build') {
steps {
// prepare docker build context
sh "cp target/project.war ./tmp-docker-build-context"
// Build and push image with Jenkins' docker-plugin
script {
withDockerServer([uri: "tcp://<my-docker-socket>"]) {
withDockerRegistry([credentialsId: 'docker-registry-credentials', url: "https://<my-docker-registry>/"]) {
// we give the image the same version as the .war package
def image = docker.build("<myDockerRegistry>/<myDockerProjectRepo>:${branchVersion}", "--build-arg PACKAGE_VERSION=${branchVersion} ./tmp-docker-build-context")
image.push()
}
}
}
}
}

只需避免使用docker DSL；它与声明性不兼容。还要避免script块。只需 withDockerServer([uri: "tcp://<my-docker-socket>"]) {
withDockerRegistry([credentialsId: 'docker-registry-credentials', url: "https://<my-docker-registry>/"]) {
sh '''
docker build -t whatever .
docker push whatever
# or better, put all this stuff into a versioned Bash/Python/etc. script
'''
}
}

目前似乎有一个未解决的问题。另一个用户也遇到了相同的问题，并添加了以下注释：为什么节点上下文和阶段上下文之间有区别

也许显示这两个案例的例子？@DanCornilescu更新了
