Skaffold 图像标记的环境变量

Question

I'm just starting using Skaffold for Kubernetes development and I'm not able to tag the docker images created as I intended with environment variables as shown

tagPolicy:
    envTemplate:
      template: '{{.SERVER_DEV_IMAGE_TAG}}'
    # dateTime:
    #   format: "2006-01-02_15-04-05.999_MST"
    #   timezone: "Local"

using dateTime works as expected but I'm not sure I'm setting correctly the environment variable I mean to use..

I added export SERVER_DEV_IMAGE_TAG=dev to zshrc via vim ~/.zshrc or code ~/.zshrc but still but image has the :latest tag..tried SERVER_DEV_IMAGE_TAG="dev" but didn't make a difference..

what am I doing wrong? Many thanks Cheers

Maybe you need double-quotes around the template? Like

template: "{{.SERVER_DEV_IMAGE_TAG}}"

I say this because single quotes ' do not expand the variable defined in your environment and will translate to a literal SERVER_DEV_IMAGE_NAME . If put inside double quotes " , this will be exanded and interpreted as $SERVER_DEV_IMAGE_TAG .

Otherwise, there is no reason for this to not work. As per the docs here .
