Custom volumes with gltlab-runner helm installation - kubernetes

Question

For faster builds I want to reuse my gradle-user-home in gitlab-runner. To achieve this I created a pvc and want to mount it on my build-containers. Can I do this with the default helm-chart?

Answer 1

So if you see here. There are no PVCs (Physical Volume Claims) or PVs (Physical Volumes) defined on the default Helm Chart.
You'd have to have something like this:
volumeMounts:
- name: gradle-user-home <== add this
mountPath: /path/to/home
subPath: home
- name: runner-secrets
mountPath: /secrets
- name: etc-gitlab-runner
mountPath: /home/gitlab-runner/.gitlab-runner
- name: scripts
mountPath: /scripts
{{- if .Values.certsSecretName }}
- name: custom-certs
readOnly: true
mountPath: /home/gitlab-runner/.gitlab-runner/certs/
{{- end }}
resources:
{{ toYaml .Values.resources | indent 10 }}
volumes:
- name: runner-secrets
emptyDir:
medium: "Memory"
- name: etc-gitlab-runner
emptyDir:
medium: "Memory"
- name: init-runner-secrets
projected:
sources:
{{- if .Values.runners.cache }}
- secret:
name: {{ template "gitlab-runner.cache.secret" . }}
items:
- key: accesskey
path: s3-access-key
- key: secretkey
path: s3-secret-key
{{- end }}
- secret:
name: {{ template "gitlab-runner.secret" . }}
items:
- key: runner-registration-token
path: runner-registration-token
- key: runner-token
path: runner-token
{{- if .Values.certsSecretName }}
- name: custom-certs
secret:
secretName: {{ .Values.certsSecretName }}
{{- end }}
- name: scripts
configMap:
name: {{ template "gitlab-runner.fullname" . }}
volumeClaimTemplates: <== Add this
- metadata:
name: gradle-user-home
spec:
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 10Gi
Note the this is only a rough draft template. You'll have to convert to the appropriate Helm template if you want to make it a Helm chart. (This happens to be a Golang template)
You don't have to modify the template if you don't want to. You can directly modify your deployment if you'd like with: kubectl -n <namespace> edit deployment <gitlab-runner-deployment>
Also if you are using PVCs (Physical Volume Claims), you'll have to define a default Kubernetes Storage Class
Hope it helps!
