最终,我正在尝试获取字符串数组,例如通过头盔配置在我的js应用中['foo', 'bar']
。
./ vars / dev / organizations.yaml
...
organizations:
- 'foo'
- 'bar'
...
./ templates / configmap.yaml
...
data:
organizations.yaml: |
organizations: "{{ toYaml .Values.organizations | indent 4 }}"
...
./ templates / deployment.yaml
...
containers:
args:
- "--organizations-config"
- "/etc/app/cfg/organizations.yaml"
...
index.js
...
const DEFAULT_ORGANIZATIONS_PATH = './vars/local/organizations.yaml'
const program = require('commander')
program
.option(
'--organizations-config <file path>',
'The path to the organizations config file.', DEFAULT_ORGANIZATIONS_PATH)
.parse(process.argv)
function readConfigs () {
return Promise.all(configs.map(path => {
return new Promise((resolve, reject) => {
fs.readFile(path, (err, data) => {
err ? reject(err) : resolve(yaml.safeLoad(data))
})
})
}))
}
readConfigs()
.then(configs => {
let organizationsConfig = configs[3]
console.log('organizationsConfig = ', organizationsConfig)
console.log('organizationsConfig.organizations = ', organizationsConfig.organizations)
...
上面的输出是:
organizationsConfig = { organizations: ' - foo - bar' }
organizationsConfig.organizations = - foo - bar
如何修改头盔配置,以使organizationsConfig.organizations
为['foo', 'bar']
答案 0 :(得分:4)
获取所需输出的一种方法是更改:
...
organizations:
- 'foo'
- 'bar'
...
收件人:
organizations: |
[ 'foo', 'bar']
因此helm将其视为单个字符串。我们碰巧知道它包含数组内容,但是舵只认为它是一个字符串。然后我们可以直接在configmap中设置该字符串:
organizations: {{ .Values.organizations | indent 4 }}
这是the grafana chart does的作用,它首先迫使用户以所需格式指定列表。也许您希望从helm值中获取一个数组并将其转换为所需的格式,在我看来,这是json格式。为此,您可以遵循example of the vault chart。因此,configmap行变为:
organizations: {{ .Values.organizations | toJson | indent 4 }}
然后,用户输入的Yaml可以与您最初拥有的一样,即真正的Yaml数组。我尝试了此方法,但它确实有效,但我注意到它提供了双引号内容,例如["foo","bar"]
另一种方法是:
organizations:
{{- range .Values.organizations }}
- {{ . }}
{{- end }}

有时候,根本原因是您忘记了用引号将每个项目括起来:
organizations:
{{- range .Values.organizations }}
- {{ . | quote }} # <-- SEE Here
{{- end }}
