I have Jenkins pipeline which builds docker image of spring boot application and push that image to AWS ECR.We have created ECS cluster which takes this image from ECR repository and runs container using ECS task and services.
We have created ECS cluster manually.But now i want whenever a new image is pushed by my CICD to ECR repository it should take the new image and create new task definition and run automatically.What are the ways to achieve this ?

As far this step is a concern, it would more easy to do with code pipeline as there is no out of the box feature in Jenkins which can detect changes in ECR image.
The completed pipeline detects changes to your image, which is
stored in the Amazon ECR image repository, and uses CodeDeploy to
route and deploy traffic to an Amazon ECS cluster and load balancer.
CodeDeploy uses a listener to reroute traffic to the port of the
updated container specified in the AppSpec file. The pipeline is also
configured to use a CodeCommit source location where your Amazon ECS
task definition is stored. In this tutorial, you configure each of
these AWS resources and then create your pipeline with stages that
contain actions for each resource.

If you are looking for this thing in Jenkins, then you have to manage these things at your end.
Here will be the step
Push image to ECR
re-use the image name and Create Task definition in your jenkins job using aws-cli or ecs-cli with same image name
Create service with new task definitioni

We ended up to the same conclusion, as there was no exact tooling matching this scenario. So we developed a little "glueing" tool from fee others open-source ones, and recently open-sourced as well:

Please have a look, since we're sharing templates for Jenkins, as it's our pipeline orchestrator as well.

I have a docker container which I push to GCR like gcloud builds submit --tag gcr.io/<project-id>/<name>, and when I deploy it on GCE instance, every time I deploy it creates a new instance and I have to remove the old instance manually. The question is, is there a way to deploy containers and force the GCE instances to fetch new containers? I need exactly GCE, not Google Cloud Run or other because it is not an HTTP service.
I deploy the container from Google Console using the Deploy to Cloud Run button
I'm posting this Community Wiki for better visibility. In the comment section there were already a few good solutions, however at the end OP wants to use Cloud Run.
At first I'd like to clarify a few things.
I have a docker container which I push to GCR like gcloud builds submit
gcloud builds submit is a command to build using Google Cloud Build.
Cloud Build is a service that executes your builds on Google Cloud Platform infrastructure. Cloud Build can import source code from Cloud Storage, Cloud Source Repositories, GitHub, or Bitbucket, execute a build to your specifications, and produce artifacts such as Docker containers or Java archives.
In this question, OP is referring to Container Registry, however GCP recommends to use Artifact Registry which soon will replace Container Registry.
Pushing and pulling images from Artifact Registry is explained in Pushing and pulling images documentation. It can be done by docker push or docker pull command, where earlier you have to tag an image and create Artifact Registry.
Deploying on different GCP products
Regarding deploying on GCE, GKE and Cloud Run, those are GCP products which are quite different from each.
GCE is IaaS where you are specifying the amount of resources and you are maintaining all the installation of all software (you would need to install Docker, Kubernetes, programming libs, etc).
GKE is like Hybrid as you mention the amount of resources you need but it's customized to run containers on it. After creation you already have docker, kubernetes and other software needed to run containers on it.
Cloud Run is a serverless GCP product, where you don't need to calculate the amount of needed resources, installing software/libs, it's a fully managed serverless platform.
When you want to deploy a container app from Artifact Registry / Container Registry, you are creating another VM (GCE and GKE) or new service (Cloud Run).
If you would like to deploy new app on the same VM:
On GCE, you would need to pull an image and deploy it on that VM using Docker or Kubernetes (Kubeadm).
On GKE you would need to deploy a new deployment using command like
kubectl create deployment test --image=<location>-docker.pkg.dev/<projectname>/<artifactRegistryName>/<imageName>
and delete the old one.
In Cloud Run you can deploy an app without concerns about resources or hardware, which steps are described here. You can create revisions for specific changes in the image. However Cloud Run also allows CI/CD using GitHub, BitBucket or Cloud Source Repositories. This process is also well described in GCP documentation - Continuous deployment
Possible solutions:
Write a Cloudbuild.yaml file that do that for you at each CI/CD pipeline run
Write a small application on GCE that subscribes to Pub/Sub notifications created by Cloud Build. You can then either pull the new container or launch a new instance.
Use Cloud Run with CI/CD.
Based on one of the OP's comments, as chosen solution was to use Cloud Run with CI/CD.
I've got an existing FargateCluster with a running service and a running task definition created by the great aws-cdk.
I wonder what is the best way to deploy a new docker image to this existing Fargate-Service within a seperate AWS CDK routine/script/class? The docker image gets a new version (not latest) and I like to keep all the parameters configured in the existing task-definition and just deploy the new docker image. What I like to do in detail is geting the existing task-definition and just change the name of the image and let Fargate deploy it.
Is there any working example for this?
Any help will be appreciated.....
Regards
Christian
I would suggest exploring using Codepipeline to deploy your app in this case.
There's a very specific codepipeline action to Deploy ECS Fargate images.
If you want to start writing your own pipeline, check the standard Codepipeline package or try the cdk specific Pipelines package.
Other option would be to rerun your existent deployment and let CloudFormation deal with the changes.
I want to deploy an image docker which is in my private docker registry, I don't know how to deploy it and on which server ( tomcat, Kubernetes? or ....).
I want to do it with a job or pipeline Jenkins in the same machine. Thank you for your proposals
There are many ways to address this, a sample action would be something like this
Have a Dockerfile with required statements as per your requirement within your codebase or context path
Create a jenkins pipeline with docker plugin(you may have to set the credentials of your private registry in plugins section)
Let it build and push based on hook or manual action.
Makesure you tag your images well and keep them unique.
So many CICD tools use a git trigger to start the pipeline, but I want to use a new image upload to Docker registry. I have my own self-hosted Docker registry. Whenever a new image is pushed to the registry, I want to then automatically deploy that image into a workload in Kubernetes. It seems like this would be simple enough, but so far I'm coming up short.
It seems like it might be possible, but I'd like to know whether it is before I spend too much time on it.
The sequence of events would be:
A new image is pushed to the Docker registry
Either the registry calls a webhook or some external process polls the registry and discovers the image
Based on the base image name, the CICD pipeline updates a specific workload in Kubernetes to pull the new image
A couple of other conditions: the CICD tool has to be self-hosted. I want everything to be self-contained within a VPC, so there would be no traffic leaving the network containing the registry, the CD tool, and the Kubernetes cluster.
Has anyone set up something like this or has actual knowledge of how to do so?
Sounds like the perfect job for Flux.
There are a handful of other tools you can try:

I am trying to implement CI/CD pipeline for my Spring Boot micro service deployment. I am planned to use Jenkins and Kubernetes for Making CI/CD pipeline. And I have one SVN code repository for version control.
Nature Of Application
Nature of my application is, one microservice need to deploy for multiple tenant. Actually code is same but database configuration is different for different tenant. And I am managing the configuration using Spring cloud config server.
My Requirement
My requirement is that, when I am committing code into my SVN code repository, then Jenkins need to pull my code, build project (Maven), And need to create Docker Image for multiple tenant. And need to deploy.
Here the thing is that, commit to one code repository need to build multiple docker image from same code repo. Means one code repo - multiple docker image building process. Actually, Dockerfile containing different config for different docker image ie. for different tenant. So here my requirement is that I need to build multiple docker images for different tenant with different configuration added in Dockerfile from one code repo by using Jenkins
My Analysis
I am currently planning to do this by adding multiple Jenkins pipeline job connect to same code repo. And within Jenkins pipeline job, I can add different configuration. Because Image name for different tenant need to keepdifferent and need to push image into Dockerhub.
My Confusion
Here my confusion is that,
Can I add multiple pipeline job from same code repository using Jenkins?
If I can add multiple pipeline job from same code repo, How I can deploy image for every tenant to kubernetes ? Do I need to add jobs for deployment? Or one single job is enough to deploy?
You seem to be going about it a bit wrong.
Since your code is same for all the tenants and only difference is config, you should better create a single docker image and deploy it along with tenant specific configuration when deploying to Kubernetes.
So, your changes in your repository will trigger one Jenkins build and produce one docker image. Then you can have either multiple Jenkins jobs or multiple steps in pipeline which deploy the docker image with tenant specific config to Kubernetes.
If you don't want to heed to above, here are the answers to your questions:
You can create multiple pipelines from same repository in Jenkins. (Select New item > pipeline multiple times).
You can keep a list of tenants and just loop through OR run all deployments in parallel in a single pipeline stage.
