GCP	Cloud Blog	Ship your Go applications faster to Cloud Run with ko	https://cloud.google.com/blog/topics/developers-practitioners/ship-your-go-applications-faster-cloud-run-ko/	Ship your Go applications faster to Cloud Run with koAs developers work more and more with containers it is becoming increasingly important to reduce the time to move from source code to a deployed application To make building container images faster and easier we have built technologies like Cloud Build ko Jib Nixery and added support for cloud native Buildpacks Some of these tools focus specifically on building container images directly from the source code without a Docker engine or a Dockerfile The Go programming language specifically makes building container images from source code much easier This article focuses on how a tool we developed named “ko can help you deploy services written in Go to Cloud Run faster than Docker build push and how it compares to alternatives like Buildpacks How does ko work ko is an open source tool developed at Google that helps you build container images from Go programs and push them to container registries including Container Registry and Artifact Registry ko does its job without requiring you to write a Dockerfile or even install Docker itself on your machine ko is spun off of the go containerregistry library which helps you interact with container registries and images This is for a good reason The majority of ko s functionality is implemented using this Go module Most notably this is what ko does Download a base image from a container registryStatically compile your Go binaryCreate a new container image layer with the Go binaryAppend that layer to the base image to create a new imagePush the new image to the remote container registryBuilding and pushing a container image from a Go program is quite simple with ko In the command above we specified a registry for the resulting image to be published and then specified a Go import path the same as what we would use in a “go build command i e the current directory in this case to refer to the application we want to build  By default the ko command uses a secure and lean base image from the Distroless collection of images the gcr io distroless static nonroot image which doesn t contain a shell or other executables in order to reduce the attack surface of the container With this base image the resulting container will have CA certificates timezone data and your statically compiled Go application binary ko also works with Kubernetes quite well For example with ko resolve and ko apply commands you can hydrate your YAML manifests as ko replaces your image references in YAML automatically with the image it builds so you can deploy the resulting YAML to the Kubernetes cluster with kubectl Using ko with Cloud RunBecause of ko s composable nature you can use ko with gcloud command line tools to build and push images to Cloud Run with a single command This works because ko outputs the full pushed image reference to the stdout stream which gets captured by the shell and passed as an argument to gcloud via the image flag Similar to Kubernetes ko can hydrate your YAML manifests for Cloud Run if you are deploying your services declaratively using YAML In the command above ko resolve replaces the Go import paths in the image … values of your YAML file and sends the output to stdout which is passed to gcloud over a pipe gcloud reads the hydrated YAML from stdin due to the argument and deploys the service to Cloud Run For this to work the image field in the YAML file needs to list the import path of your Go program using the following syntax Ko compared to its alternativesAs we mentioned earlier accelerating the refactor build deploy test loop is crucial for developers iterating on their applications To illustrate the speed gains made possible by using ko in addition to the time and system resources you ll save by not having to write a Dockerfile or run Docker we compared it to two common alternatives Local docker build and docker push commands with a Dockerfile Buildpacks no Dockerfile but runs on Docker Below is the performance comparison for building a sample Go application into a container image and pushing this image to Artifact Registry Note In this chart cold builds do not cache layers either in the build machine or in the container registry In contrast warm builds cache both layers if caching is enabled by default and skip pushing the layer blobs to the registry if they already exist ko vs local Docker Engine ko wins here by a small margin This is because the docker build command packages your source code into a tarball and sends it to the Docker engine which either runs natively on Linux or inside a VM on macOS Windows  Then Docker builds the image by spinning up a new container for Dockerfile instruction and snapshots the filesystem of the resulting container into an image layer These steps can take a while ko does not have these shortcomings it directly creates the image layers without spinning up any containers and pushes the resulting layer tarballs and image manifest to the registry In this approach we built and pushed the Go application using the following command ko vs Buildpacks on local Docker  Buildpacks help you build images for many languages without having to write a Dockerfile It s worth noting that Buildpacks still require Docker to work Buildpacks work by detecting your language and using a “builder image that has all the build tools installed before finally copying the resulting artifacts into a smaller image In this case the builder image gcr io buildpacks builder v is around MB so it will show up in the cold builds However even for warm builds Buildpacks use a local Docker engine which is already slower than ko And similarly Buildpacks will run custom logic during the build phase so it is also slower than Docker In this approach we built and pushed the Go application using the following command Conclusionko is part of a larger effort to make developers lives easier by simplifying how container images are built With buildpacks support you can build container images out of many programming languages without writing Dockerfiles at all and then you can deploy these images to Cloud Run with a single command ko helps you build your Go applications into container images and makes it easy to deploy them to Kubernetes or Cloud Run ko is not limited to the Google Cloud ecosystem It can authenticate to any container registry and works with any Kubernetes cluster To learn more make sure to check out ko documentation at the GitHub repository and try deploying some of your own Go services to Cloud Run Related ArticleStreamlining Cloud

GCP	Cloud Blog	Discover and invoke services across clusters with GKE multi-cluster services	https://cloud.google.com/blog/products/containers-kubernetes/introducing-gke-multi-cluster-services/	Discover and invoke services across clusters with GKE multi cluster servicesDo you have a Kubernetes application that needs to span multiple clusters Whether for privacy scalability availability cost management and data sovereignty reasons it can be hard for platform teams to architect implement operate and maintain applications across cluster boundaries as Kubernetes Service primitive only enables service discovery within the confines of a single Kubernetes cluster  Today we are announcing the general availability of multi cluster services MCS a Kubernetes native cross cluster service discovery and invocation mechanism for Google Kubernetes Engine GKE the most scalable managed Kubernetes offering MCS extends the reach of the Kubernetes Service primitive beyond the cluster boundary so you can easily build Kubernetes applications that span multiple clusters  This is especially important for cloud native applications which are typically built using containerized microservices The one constant with microservices is changeーmicroservices are constantly being updated scaled up scaled down and redeployed throughout the lifecycle of an application and the ability for microservices to discover one another is critical GKE s new multi cluster services capability makes managing cross cluster microservices based apps simple  How does GKE MCS work GKE MCS leverages the existing service primitive that developers and operators are already familiar with making expanding into multiple clusters consistent and intuitive Services enabled with this feature are discoverable and accessible across clusters with a virtual IP matching the behavior of a ClusterIP service within a cluster Just like your existing services services configured to use MCS are compatible with community driven open APIs ensuring your workloads remain portable The GKE MCS solution leverages environs to group clusters and is powered by the same technology offered by Traffic Director Google Cloud s fully managed enterprise grade platform for global application networking Common MCS use casesMercari a leading e commerce company and an early adopter of MCS “We have been running all our microservices in a single multi tenant GKE cluster For our next generation Kubernetes infrastructure we are designing multi region homogeneous and heterogeneous clusters Seamless inter cluster east west communication is a prerequisite and multi cluster Services promise to deliver Developers will not need to think about where the service is running We are very excited at the prospect Vishal Banthia Engineering Manager Platform Infra Mercari We are excited to see how you use MCS to deploy services that span multiple clusters to deliver solutions optimized for your business needs Here are some popular use cases we have seen our customers enable with GKE MCS High availability Running the same service across clusters in multiple regions provides improved fault tolerance In the event that a service in one cluster is unavailable the request can fail over and be served from another cluster or clusters With MCS it s now possible to manage the communication between services across clusters to improve the availability and resiliency of your applications to meet service level objectives Stateful and stateless services Stateful and stateless services have different operational dependencies and complexities and present different operational tradeoffs Typically stateless services have less of a dependency on migrating storage making it easier to scale upgrade and migrate a workload with high availability MCS lets you separate an application into separate clusters for stateful and stateless workloads making them easier to manage Shared services Increasingly customers are spinning up separate Kubernetes clusters to get higher availability better management of stateful and stateless services and easier compliance with data sovereignty requirements However many services such as logging monitoring Prometheus secrets management Vault or DNS are often shared amongst all clusters to simplify operations and reduce costs Instead of each cluster requiring its own local service replica MCS makes it easy to set up common shared services in a separate cluster that is used by all functional clusters Migration Modernizing an existing application into a containerized microservices based architecture often requires services to be deployed across multiple Kubernetes clusters MCS provides a mechanism to help bridge the communication between those services making it easier to migrate your applicationsーespecially when the same service can be deployed in two different clusters and traffic is allowed to shift Multi cluster Services amp Multi cluster IngressMCS also complements Multi cluster Ingress  with multi cluster load balancing for both East West and North South traffic flows Whether your traffic flows from the internet across clusters within the VPC between clusters or both GKE provides multi cluster networking that is deeply integrated and Kubernetes native  Get started with GKE multi cluster services todayYou can start using multi cluster services in GKE today and gain the benefits of higher availability better management of shared services and easier
