来自文件的新Kubernetes ConfigMap-加号? [英] New Kubernetes ConfigMap from file - plus sign?

问题描述

只需运行以下命令即可从文件创建新的ConfigMap:
kubernetes create configmap foo --from-file=foo

Just ran the following command to create a new ConfigMap from a file:
kubernetes create configmap foo --from-file=foo

创建成功.

现在我跑步时，
kubernetes get configmaps foo -o yaml

Now when I run,
kubernetes get configmaps foo -o yaml

我在结果输出中看到以下几行:

I see the following lines in the resulting output:

apiVersion: v1
data:
  foo: |+
    VAR1=value1
    VAR2=value2

此行中的加号是什么意思?
foo: |+

它没有出现在我的其他任何ConfigMap中.

It doesn't appear in any of my other ConfigMaps.

推荐答案

|+不是特定于kubernetes的，它是yaml的一部分.

|+ is not kubernetes specific, it's part of yaml.

来自 http://lzone.de/cheat-sheet/YAML :

# + indicator (keep extra newlines after block)
content: |+
   Arbitrary free text with two newlines after


foo: ...
