kubernetes - Kubernetes + Helm-仅在新版本/更改时重新启动Pod

Question

每当我运行基本的deploy命令时，一切都将重新部署到我的环境中。是否有任何方法告诉Helm仅在进行更改后才应用这些东西，或者这仅仅是它的工作方式？
我在跑:

helm upgrade --atomic MyInstall . -f CustomEnvironmentData.yaml

我在 Helm Upgrade documentation中没有看到任何表明该功能的东西。
除非必须，否则我不想弹跳整个环境。

您可能应该使用helm diff upgrade https://github.com/databus23/helm-diff

$ helm diff upgrade - h
Show a diff explaining what a helm upgrade would change.

    This fetches the currently deployed version of a release
    and compares it to a chart plus values.
    This can be used visualize what changes a helm upgrade will
perform.

    Usage:
diff upgrade[flags] [RELEASE] [CHART]

Examples:
helm diff upgrade my-release stable / postgresql--values values.yaml

Flags:
-h, --help                   help for upgrade
    --detailed - exitcode      return a non - zero exit code when there are changes
--post - renderer string the path to an executable to be used for post rendering. If it exists in $PATH, the binary will be used, otherwise it will try to look for the executable at the given path
--reset - values           reset the values to the ones built into the chart and merge in any new values
    --reuse - values           reuse the last release's values and merge in any new values
    --set stringArray        set values on the command line(can specify multiple or separate values with commas: key1 = val1, key2 = val2)
--suppress stringArray   allows suppression of the values listed in the diff output
    - q, --suppress - secrets       suppress secrets in the output
    - f, --values valueFiles      specify values in a YAML file(can specify multiple)(default[])
    --version string         specify the exact chart version to use.If this is not specified, the latest version is used

    Global Flags:
--no - color   remove colors from the output
