在头盔安装之前将go二进制文件移动到吊舱的惯用方式是什么？

Question

I use CircleCI to build a go binary that I want to run in a pod installed by Helm charts. I want to move the binary from CircleCI to the remote cluster so it's available when the pod starts. I know it's possible with volumes, like ConfigMap or Secrets but I'm not sure what the best way to do this.

I once made it work with a private docker registry and a kubernetes Secrets for the credentials of the registry but I don't like this option. I don't want to have to build and push a new docker image on every binary change.

version: 2.1
jobs:
  build_and_deploy:
    docker:
      - image: circleci/golang:1.12.7
    steps:
      - checkout
      - run: go get -v -t -d ./...
      - run: go build cmd/main.go
      - run: ...
      - run: helm install

workflows:
  version: 2
  build:
    jobs:
      - build_and_deploy:

The expected result should be a new binary available on the cluster every time the job runs.

Your CI/CD should simply build a Docker container with that binary. Then you should push it to the private repository. Cluster should download the binary.
