Build and deploy Go applications on Kubernetes


ko: Easy Go Containers

Travis Build Status GitHub Actions Build Status GoDoc Go Report Card

ko is a simple, fast container image builder for Go applications.

It's ideal for use cases where your image contains a single Go application without any/many dependencies on the OS base image (e.g., no cgo, no OS package dependencies).

ko builds images by effectively executing go build on your local machine, and as such doesn't require docker to be installed. This can make it a good fit for lightweight CI/CD use cases.

ko also includes support for simple YAML templating which makes it a powerful tool for Kubernetes applications (See below).



Install from Releases

VERSION=TODO # choose the latest version
OS=Linux     # or Darwin
ARCH=x86_64  # or arm64, i386, s390x
curl -L${VERSION}/ko_${VERSION}_${OS}_${ARCH}.tar.gz | tar xzf - ko
chmod +x ./ko

Install using Homebrew

brew install ko

Build and Install from Source

With Go 1.16+, build and install the latest released version:

go install


ko depends on the authentication configured in your Docker config (typically ~/.docker/config.json). If you can push an image with docker push, you are already authenticated for ko.

Since ko doesn't require docker, ko login also provides a surface for logging in to a container image registry with a username and password, similar to docker login.

Choose Destination

ko depends on an environment variable, KO_DOCKER_REPO, to identify where it should push images that it builds. Typically this will be a remote registry, e.g.:

  •, or
  • KO_DOCKER_REPO=my-dockerhub-user

Build an Image

ko publish ./cmd/app builds and pushes a container image, and prints the resulting image digest to stdout.

ko publish ./cmd/app

Because the output of ko publish is an image reference, you can easily pass it to other tools that expect to take an image reference:

To run the container:

docker run -p 8080:8080 $(ko publish ./cmd/app)

Or, for example, to deploy it to other services like Cloud Run:

gcloud run deploy --image=$(ko publish ./cmd/app)


Aside from KO_DOCKER_REPO, you can configure ko's behavior using a .ko.yaml file. The location of this file can be overridden with KO_CONFIG_PATH.

Overriding Base Images

By default, ko bases images on This is a small image that provides the bare necessities to run your Go binary.

You can override this base image in two ways:

  1. To override the base image for all images ko builds, add this line to your .ko.yaml file:
  1. To override the base image for certain importpaths:

Naming Images

ko provides a few different strategies for naming the image it pushes, to workaround certain registry limitations and user preferences:

Given, by default, ko publish ./cmd/app will produce an image named like<md5>, which includes the MD5 hash of the full import path, to avoid collisions.

  • --preserve-import-path (-P) will include the entire importpath:
  • --base (-B) will omit the MD5 portion:
  • --bare will only include the KO_DOCKER_REPO:

Local Publishing Options

ko is normally used to publish images to container image registries, identified by KO_DOCKER_REPO.

ko can also publish images to a local Docker daemon, if available, by setting KO_DOCKER_REPO=ko.local, or by passing the --local (-L) flag.

ko can also publish images to a local KinD cluster, if available, by setting KO_DOCKER_REPO=kind.local.

Multi-Platform Images

Because Go supports cross-compilation to other CPU architectures and operating systems, ko excels at producing multi-platform images.

To build and push an image for all platforms supported by the configured base image, simply add --platform=all. This will instruct ko to look up all the supported platforms in the base image, execute GOOS=<os> GOARCH=<arch> GOARM=<variant> go build for each platform, and produce a manifest list containing an image for each platform.

You can also select specific platforms, for example, --platform=linux/amd64,linux/arm64

Static Assets

ko can also bundle static assets into the images it produces.

By convention, any contents of a directory named <importpath>/kodata/ will be bundled into the image, and the path where it's available in the image will be identified by the environment variable KO_DATA_PATH.

As an example, you can bundle and serve static contents in your image:


Then, in your main.go:

func main() {
    http.Handle("/", http.FileServer(http.Dir(os.Getenv("KO_DATA_PATH"))))
    log.Fatal(http.ListenAndServe(":8080", nil))

You can simulate ko's behavior outside of the container image by setting the KO_DATA_PATH environment variable yourself:

KO_DATA_PATH=cmd/app/kodata/ go run ./cmd/app

Tip: Symlinks in kodata are followed and included as well. For example, you can include Git commit information in your image with:

ln -s -r .git/HEAD ./cmd/app/kodata/

Kubernetes Integration

You could stop at just building and pushing images.

But, because building images is so easy with ko, and because building with ko only requires a string importpath to identify the image, we can integrate this with YAML generation to make Kubernetes use cases much simpler.

YAML Changes

Traditionally, you might have a Kubernetes deployment, defined in a YAML file, that runs an image:

apiVersion: apps/v1
kind: Deployment
  name: my-deployment
  replicas: 3
      - name: my-app

...which you apply to your cluster with kubectl apply:

kubectl apply -f deployment.yaml

With ko, you can instead reference your Go binary by its importpath, prefixed with ko://:

      - name: my-app
        image: ko://

ko resolve

With this small change, running ko resolve -f deployment.yaml will instruct ko to:

  1. scan the YAML file(s) for values with the ko:// prefix,
  2. for each unique ko://-prefixed string, execute ko publish <importpath> to build and push an image,
  3. replace ko://-prefixed string(s) in the input YAML with the fully-specified image reference of the built image(s), for example:
    - name: my-app
  1. Print the resulting resolved YAML to stdout.

The result can be redirected to a file, to distribute to others:

ko resolve -f config/ > release.yaml

Taken together, ko resolve aims to make packaging, pushing, and referencing container images an invisible implementation detail of your Kubernetes deployment, and let you focus on writing code in Go.

ko apply

To apply the resulting resolved YAML config, you can redirect the output of ko resolve to kubectl apply:

ko resolve -f config/ | kubectl apply -f -

Since this is a relatively common use case, the same functionality is available using ko apply:

ko apply -f config/

NB: This requires that kubectl is available.

ko delete

To teardown resources applied using ko apply, you can run ko delete:

ko delete -f config/

This is purely a convenient alias for kubectl delete, and doesn't perform any builds, or delete any previously built images.

Frequently Asked Questions

How can I set ldflags?

Using -ldflags is a common way to embed version info in go binaries (In fact, we do this for ko!). Unforunately, because ko wraps go build, it's not possible to use this flag directly; however, you can use the GOFLAGS environment variable instead:

GOFLAGS="-ldflags=-X=main.version=1.2.3" ko publish .

Why are my images all created in 1970?

In order to support reproducible builds, ko doesn't embed timestamps in the images it produces by default; however, ko does respect the SOURCE_DATE_EPOCH environment variable.

For example, you can set this to the current timestamp by executing:

export SOURCE_DATE_EPOCH=$(date +%s)

or to the latest git commit's timestamp with:

export SOURCE_DATE_EPOCH=$(git log -1 --format='%ct')

Can I optimize images for eStargz support?

Yes! Set the environment variable GGCR_EXPERIMENT_ESTARGZ=1 to produce eStargz-optimized images.

Does ko support autocompletion?

Yes! ko completion generates a Bash completion script, which you can add to your bash_completion directory:

ko completion > /usr/local/etc/bash_completion.d/ko

Or, you can source it directly:

source <(ko completion)

Does ko work with Kustomize?

Yes! ko resolve -f - will read and process input from stdin, so you can have ko easily process the output of the kustomize command.

kustomize build config | ko resolve -f -


This work is based heavily on learnings from having built the Docker and Kubernetes support for Bazel. That work was presented here.

    I haven't actually tested pulling/running this on different platforms (I don't have any), so YMMV, but publishing works 👍

    I don't actually like this very much because I've made every package deal with a new abstraction (I've called it Steve so that we don't ever merge this) that can represent either base image or a base manifest list. A better approach would probably be to make everything deal with a manifest list to simplify things.

    When pulling base image:

    • if it's a manifest list, pass that along as the base
    • if it's an image, wrap it as a singleton manifest list

    When publishing the artifacts:

    • if it's a singleton manifest list, unwrap it and publish just the image
    • otherwise, publish it as a manifest list

    This isn't perfect (what if the user actually does want to publish a singleton manifest list?), so maybe it's not the best idea. Open to suggestions :)

    If SBOM publishing was opt-in I'd say this is WAI and fine, but it's going to be a pretty bad experience for happy ko users who push to Quay (and other similar registries) when they upgrade to the next release.

    Should we log-and-continue if SBOM publishing fails?

    Being on GitHub Actions, its build process and logs are more visible and publicly auditable.

    If this proposal is accepted, I'd like to suggest adding a warning when defaultBaseImage is not set, saying that the change is coming in a future release.

    If you want to retain the existing base image, simply add defaultBaseImage: To opt-in to the change before it's imposed on you automatically in a future release, defaultBaseImage:

    Then we cut a release with that warning, wait a release, change the default base image and remove the warning.

    ko hangs when used with ASDF installed Go

    I am able to reproduce either a bug, or a misconfiguration that could perhaps use a better error message of some sort.

    The reproduction is here at StevenACoffman/repro.


    If you clone that repo and run:

    cd sub
    ko publish -B --bare --local --platform=linux/amd64 --push=false .

    The terminal will just hang there until you hit Ctrl-c.

    At which point, it will then say:

    However, if you delete the .ko.yaml file in that directory and run it again, things work as you'd expect.

    rm .ko.yaml
    ko publish -B --bare --local --platform=linux/amd64 --push=false .

    I have tried a number of different possible values for "main" and "dir" and "id" in the .ko.yaml file, including omitting them altogether. For instance, setting the main: to the values, ., and main don't seem to affect this hanging behavior.

    .ko.yaml contents:

  • ko stops building containers after Golang updates

    ko stops building containers after Golang updates

    After each minor Golang version bump (e.g. 1.13.2 -> 1.13.3), ko apply no longer builds container images but happily applies the yaml untransformed, which leads with image pull errors on the cluster. After reinstalling ko, it works again as expected.

    Ideally ko would continue to work after a Golang update, but if not, it should fail loudly and demand to be reinstalled.

  • [WIP] Feature: Add support for verifying base image policies.

    [WIP] Feature: Add support for verifying base image policies.

    :gift: This implements the very basics from my recent comment on #356.

    This still needs a bunch of work, but some playing with it and go run seem to demonstrate what I'd hope for.

    Things I'd like to do still:

    • [x] Add validation that warns/errors if aspects of CIP irrelevant outside K8s are used (e.g. match:, includeSpec:),
    • [x] Expand unit test coverage significantly,
    • [x] Move pkg/policy upstream to sigstore/policy-controller to facilitate using this in other projects with similar ease (e.g. kaniko, buildpacks, ...)
    • [ ] e2e tests with verification failures

    /kind feature

    Nested config doesn't resolve build path as expected

    Hi, I'm struggling with using a nested config. It doesn't resolve the build path as expected and therefore the build options are not used.

    I created a minimal reproducible example here:

    The expected output in this project is: tag is used but I didn't manage to get the tag to be used ko.

  • enable guessing local environment os/arch by using local as option for platform flag

    enable guessing local environment os/arch by using local as option for platform flag

    Some of the tools are supporting to accept local as a value for their platform flag, such as Docker Buildx, regctl. So, can we do the same thing for ko instead of throwing an error like the following:

    $ ko build -B  --platform local --tags buildinfo .
    Error: failed to publish images: error building "ko://": no matching platforms in base image index

    CNCF TAG-Runtime Discussion/Presentation (?)

    Hello ko team,

    I'm one of the co-chairs of the CNCF TAG-Runtime. I believe you had an agenda item to present the project in our meeting. For example, it would be great to learn things like the roadmap, tech, community, general overview of the project.

    Feel free to add it to our agenda or reach out to me (raravena80 at at your convenience.

  • v0.9.1(Sep 21, 2021)


    v0.9.0 was released incorrectly, and should not be used.

    The full commit log since the previous release is available here:


    • enable ko's logic to be embedded in other Go programs
    • enable base images from the Docker daemon (ko.local)
    • add support for Go build flags
    • annotate built images with base image annotations
    • build working Windows images
    • implement ko deps
    • deprecate --watch

    😍 Thanks 😍

    ko wouldn't be possible without the work of its dedicated contributors. Thanks to @halvards @HeavyWombat @jonjohnsonjr @imjasonh @mattmoor

    Due to a bug in our release process, v0.9.0 does not include artifacts that would normally have been built using goreleaser. fixes this bug, and is included in v0.9.1, which you should use instead.

    1. Accidentally included d7b989a in this patch release, which may be breaking. Mea culpa -- please yell at @jonjohnsonjr to fix it if you're broken.
    2. More descriptive error messages than "importpath foo is not supported".
    3. New repo naming strategy --bare to publish everything under KO_DOCKER_REPO.
