There is a new revised PR here - I can confirm that this does work: https://github.com/jenkinsci/docker-build-publish-plugin/pull/7. Plugin Information. Once you have the angular project created, you’ll need to create a Dockerfile for the image. Each entry must be of the form IMAGE[:TAG] as per the docker tag command. The Jenkinsfile is divided into 4 stages, a clone, build, test, and push stage. It builds the docker image, does some simple tests, and pushes it to Docker Hub, using the credentials, Docker repository, and tag found in the Jenkinsfile. I have tried this and it works.

Using our Jenkins pipeline, we can take builds triggered by tags and push an associated tagged Docker image up to our registry. It’s a small Alpine based image that contains a single “fortune” phrase (/fortune.txt file), automatically generated for each image build. Under Build Configuration leave the default Jenkinsfile because this will look for the Jenkinsfile in the cloned repo. I would like to tag images both by "nightly-$BUILD_ID" tag and "latest" tag. Maybe though the checkbox is unnecessary - latest should automatically be pushed as well as the explicit tag? Unlike a resource request, this is the upper limit of resources used by your Jenkins Agent container. Follow to join our community. Then you get a hash back.

Similar to the sidecar pattern, Docker Pipeline can run one container "in the background", while performing work in another. Go back to the dashboard and select new Item. This pipeline pulls the code from Bitbucket, tests it, installs it, creates a Docker image, pushes it to the Docker registry, and rolls out any updates. kafka:0.8.1 or kafka:VERSION_28 depending on how you generated the tag, but not kafka:latest. Kubernetes Resources Limit of Memory This value can be set to control the memory resource limit passed when creating the Jenkins agent Docker container in Kubernetes. I wanted to figure out a way to create a pipeline which pulled from a Github repo, created a docker image, and pushed the image to Dockerhub. ${BUILD_NUMBER} as part of each entry. For several use cases this is fine, but for building an application Docker container, it is much nicer to implement multiple stages. kafka:0.8.1 or kafka:VERSION_28 depending on how you generated the tag, but not kafka:latest. The RUN mkdir -p /app creates an app directory and WORKDIR indicates this is where the application will be created. A Jenkins pipeline can be used for continuous integration of Docker image code. 在日常开发中，经常会有发布的需求，而且经常会碰到各种环境，比如：开发环境、测试环境、生产环境。虽然可以使用手动构建、上传服务器部署的方式，但在微服务架构下一个项目经常包含多个微服务的部署，如果用手动方式就会非常繁琐而且容易出错。使用jenkins结合SCM可以实现代码的整个自动化构建部署过程。 本文中自动构建部署过程大致完成了以下步骤： 1.
