如何解决从Helm k8s的values.yaml中获取docker映像和标签作为键/值对
我有一个Docker映像列表,我想将其作为环境变量传递给Deployment.yaml
values.yaml
contributions_list:
- image: flogo-aws
tag: 36
- image: flogo-awsec2
tag: 37
- image: flogo-awskinesis
tag: 18
- image: flogo-chargify
tag: 19
deployment.yaml
apiVersion: batch/v1
kind: Job
metadata:
name: container-image-extractor
namespace: local-tibco-tci
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
backoffLimit: 0
template:
metadata:
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
nodeSelector:
kubernetes.io/os: linux
restartPolicy: Never
containers:
- name: container-image-extractor
image: reldocker.tibco.com/stratosphere/container-image-extractor
imagePullPolicy: IfNotPresent
env:
- name: SOURCE_DOCKER_IMAGE
value: "<docker_image>:<docker_tag>" # docker image from which contents to be copied
我的问题如下。
- 这是将docker映像和标签数组作为deployment.yaml的参数传递的正确方法
- 我将如何从values.yaml中替换Deployment.yaml中的
和 ,并应为每个docker映像和标签触发增量作业。
解决方法
这就是我要做的,为列表中的每个图像创建一个工作
{{- range .Values.contributions_list }}
apiVersion: batch/v1
kind: Job
metadata:
name: "container-image-extractor-{{ .image }}-{{ .tag }}"
namespace: local-tibco-tci
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
backoffLimit: 0
template:
metadata:
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
nodeSelector:
kubernetes.io/os: linux
restartPolicy: Never
containers:
- name: container-image-extractor
image: reldocker.tibco.com/stratosphere/container-image-extractor
imagePullPolicy: IfNotPresent
env:
- name: SOURCE_DOCKER_IMAGE
value: "{{ .image }}:{{ .tag }}" # docker image from which contents to be copied
{{ end }}
如果使用此贡献列表之外的值(发行名称,env等),请不要忘记更改范围{{ $.Values.myjob.limits.cpu | quote }}
。 $.
很重要:)
编辑:如果您在循环的每次迭代中都没有更改名称,则每次都会覆盖配置。使用不同的名称,您将创建多个作业。
,您需要按以下步骤修复deploy.yaml:
{{- range $contribution := .Values.contributions_list }}
apiVersion: batch/v1
kind: Job
metadata:
name: container-image-extractor
namespace: local-tibco-tci
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
backoffLimit: 0
template:
metadata:
labels:
app.cloud.tibco.com/name: container-image-extractor
spec:
nodeSelector:
kubernetes.io/os: linux
restartPolicy: Never
containers:
- name: container-image-extractor
image: reldocker.tibco.com/stratosphere/container-image-extractor
imagePullPolicy: IfNotPresent
env:
- name: SOURCE_DOCKER_IMAGE
value: "{{ $contribution.image }}:{{ $contribution.tag }}"
{{- end }}
