我正在尝试为我们的产品编写Helm Charts。图像存储在GCR私人仓库中。所有组件的图表都已准备就绪,但我正在尝试在图表中为imagePullSecrets编写YAML文件。我已经阅读了here,
中的图表提示我也知道如何用:
创建imagePullSecretkubectl create secret docker-registry mydockercfg \
--docker-server "https://eu.gcr.io" \
--docker-username _json_key \
--docker-email not@val.id \
--docker-password=$(cat your_service_account.json)
但我不知道如何将“your_service_account.json”的内容填入该图表的values.yaml的密码。我可以更改名称“your_service_account.json”以更新values.yaml的密码。
目前,我的实施如下:
$ cat values.yaml
secretName: gcr-json-key-test
imageCredentials:
registry: us.gcr.io/xxxxx
username: _json_key
password:
secrets.yaml的内容:
$ cat templates/secrets.yaml
apiVersion: v1
kind: Secret
metadata:
name: {{ .Values.secretName }}
labels:
app: {{ template "fullname" . }}
chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"
release: "{{ .Release.Name }}"
heritage: "{{ .Release.Service }}"
type: kubernetes.io/dockercfg
data:
.dockerconfigjson: {{ template "imagePullSecret" . }}
_helpers.tpl的内容:
$ cat templates/_helpers.tpl
{{/*
Expand the name of the chart.
*/}}
{{- define "name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{/*
Create a default fully qualified app name.
We truncate at 63 chars because some Kubernetes name fields are limited
to this (by the DNS naming spec).
*/}}
{{- define "fullname" -}}
{{- $name := default .Chart.Name .Values.nameOverride -}}
{{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{- define "imagePullSecret" }}
{{- printf "{\"auths\": {\"%s\": {\"auth\": \"%s\"}}}" .Values.imageCredentials.registry (printf "%s:%s" .Values.imageCredentials.username .Values.imageCredentials.password | b64enc) | b64enc }}
{{- end }}
然后使用
$ helm install ./secrets --set imageCredentials.password "$(cat ./my_service_account.json)"
会导致错误:
错误:此命令需要1个参数:图表名称
我该如何解决这个问题?

可以使用以下步骤创建和部署它:
<强>步骤:强>
使用docker_username和docker_password
创建base64编码的字符串$ echo -n "docker_username:docker_password" | base64
ZG9rY2VyX3VzZXI6ZG9ja2VyX3Bhc3N3b3Jk
将步骤1 中获得的编码字符串作为 auth 键的值放在以下Json中,并填写所需的详细信息。
{
"https://eu.gcr.io":
{
"username":"docker_user",
"password":"docker_password",
"email":"docker@gamil.com",
"auth":"ZG9rY2VyX3VzZXI6ZG9ja2VyX3Bhc3N3b3Jk",
}
}
将此 json 缩减为由单引号括起的字符串:
'{"https://eu.gcr.io":{"username":"docker_user","password":"docker_password","email":"docker@gamil.com","auth":"ZG9rY2VyX3VzZXI6ZG9ja2VyX3Bhc3N3b3Jk"}}'
为上述Json字符串创建base64编码字符串,如下所示:
$ echo -n '{"https://eu.gcr.io":{"username":"docker_user","password":"docker_password","email":"docker@gamil.com","auth":"ZG9rY2VyX3VzZXI6ZG9ja2VyX3Bhc3N3b3Jk"}}' | base64

按以下格式创建secret.yml:
$ cat templates/secrets.yaml
apiVersion: v1
kind: Secret
metadata:
name: {{ .Values.secretName }}
labels:
app: {{ template "fullname" . }}
chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"
release: "{{ .Release.Name }}"
heritage: "{{ .Release.Service }}"
type: kubernetes.io/dockercfg
data:
.dockercfg: {{ .Values.dockercfg }}
将步骤4 中获得的编码字符串放在value.yaml中:
$ cat values.yaml
secretName: gcr-json-key-test
dockercfg:
使用以下命令安装图表:
$ helm install ./secrets -n release_name --set dockecfg="eyJodHRwczovL2V1Lmdjci5pbyI6eyJ1c2VybmFtZSI6ImRva2Nlcl91c2VyIiwicGFzc3dvcmQiOiJkb2NrZXJfcGFzc3dvcmQiLCJlbWFpbCI6ImRvY2tlckBnYW1pbC5jb20iLCJhdXRoIjoiWkc5clkyVnlYM1Z6WlhJNlpHOWphMlZ5WDNCaGMzTjNiM0prIn19" --debug
或将其存储在文件(.dockercfg)中并使用以下命令
$ helm install ./secrets -n release_name --set dockecfg="$(cat ./.dockercfg )"
希望这会有用...... !! :)
