[英]Using the Jenkins pipeline docker plugin, how to pull an image and push a new tag to it?
I have an image already in my private repo.我的私人仓库中已经有一张图片。 I need to pull that image, create a tag and push it to the registry.
我需要提取该图像,创建一个标签并将其推送到注册表。
What's the bes way to do this using the Jenkins WithRegistry?使用 Jenkins WithRegistry 的最佳方法是什么?
Here's my actual code:这是我的实际代码:
stage("Applying to docker repo") {
steps {
script {
def imageNameLookup = configs.dockerRegistry.repo + "/"+repo.toLowerCase()+":"+params.versionToTag
echo 'looking up '+ imageNameLookup
docker.withRegistry('https://' + configs.dockerRegistry.url, configs.dockerRegistry.credentialsId) {
try {
image = docker.image(repo.toLowerCase()+":"+params.versionToTag).pull()
image.tag("${deliveryTag}")
image.push()
} catch (Exception e) {
echo ' catch 2 '+ e.getMessage()
}
}
}
}
}
When running the image.tag(), i get the following error:运行 image.tag() 时,出现以下错误:
bfc9288fe86d: Pull complete Digest: sha256:ee9b01eb62f2f21dcb3bf4af285702c8991d1789e659515fdfa2da2619f1d8b9 Status: Downloaded newer image for repodocker-xxx.xxx.xx/my-api:1.19.0 [Pipeline] echo catch 2 Cannot invoke method tag() on null object
bfc9288fe86d: Pull complete Digest: sha256:ee9b01eb62f2f21dcb3bf4af285702c8991d1789e659515fdfa2da2619f1d8b9 Status: Downloaded newer image for repodocker-xxx.xxx.xx/my-api:1.19.0 [Pipeline] echo catch 2 Cannot invoke method tag() on null object
EDIT: I was able to pull the image but when I try to create the tag, I get a new error: No such image:latest编辑:我能够提取图像,但是当我尝试创建标签时,我收到一个新错误:没有这样的图像:最新
I don't need to set the tag latest because I'm tagging another version.我不需要将标签设置为最新,因为我正在标记另一个版本。
docker.withRegistry('https://' + configs.dockerRegistry.url, configs.dockerRegistry.credentialsId) {
try {
docker.image(repo.toLowerCase()+":"+params.versionToTag).pull()
sh "docker tag ${repo.toLowerCase()} ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${deliveryTag}"
sh ""
)
} catch (Exception e) {
echo ' catch 2 '+ e.getMessage()
}
and my new log:和我的新日志:
[Pipeline] sh
+ docker pull repodocker-xxxx.xxx.xx/myapi-api:1.19.0
1.19.0: Pulling from myapi-api
Digest: sha256:ee9b01eb62f2f21dcb3bf4af285702c8991d1789e659515fdfa2da2619f1d8b9
Status: Image is up to date for repodocker-xxxx.xxx.xx/myapi-api:1.19.0
[Pipeline] sh
+ docker tag myapi-api grdocker-xxxx.xx.xx:443/xx.xxx.xxx/myapi-api:testTag20
Error response from daemon: No such image: myapi-api:latest
[Pipeline] echo
catch 2 script returned exit code 1
EDIT2 was able to do it by doing it this way: EDIT2能够通过这种方式做到这一点:
stage("Applying to docker repo") {
steps {
script {
docker.withRegistry('https://' + configs.dockerRegistry.url, configs.dockerRegistry.credentialsId) {
docker.image(repo.toLowerCase()+":"+params.versionToTag).pull()
sh "docker tag ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${params.versionToTag} ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${deliveryTag}"
sh "docker push ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${deliveryTag}"
}
}
}
}
FINAL EDIT Here's the final solution in Jenkins and the docker plugin which was not able to do everything.最终编辑这是 Jenkins 和 docker 插件中的最终解决方案,它无法完成所有操作。
stage("Applying to docker repo") {
steps {
script {
docker.withRegistry('https://' + configs.dockerRegistry.url, configs.dockerRegistry.credentialsId) {
docker.image(repo.toLowerCase()+":"+params.versionToTag).pull()
sh "docker tag ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${params.versionToTag} ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${deliveryTag}"
sh "docker push ${configs.dockerRegistry.url}/${repo.toLowerCase()}:${deliveryTag}"
docker.image(repo.toLowerCase()+":${deliveryTag}").pull()
}
}
}
}
Have installed docker-engine and your server should have access the registry:已安装 docker-engine 并且您的服务器应该可以访问注册表:
docker login ip_registry:5000
docker login ip_registry:5000
stage('registry') {
steps {
sh "docker tag ${imageName} ${registryServer}/${imageName}:latest"
sh "docker push ${registryServer}/${imageName}:latest"
}
}
Try code below to push image with new tag:尝试下面的代码来推送带有新标签的图像:
try {
image = docker.image(imageNameLookup+":"+params.versionToTag)
image.pull()
image.push("${deliveryTag}")
} catch (Exception e) {
echo ' catch 2 '+ e.getMessage()
}
