Now that Gitlab offers its own image registry, it is possible to use it directly in our K8s environment! If you missed the info (which is starting to date now), I refer you to this article.
To add the Gitlab private registry in Kubernetes you have to create a secret :
> kubectl create secret docker-registry regsecret --docker-server=registry.gitlab.xyz --docker-username='' --docker-password='' --docker-email=""
Where :
--docker-server regitry gitlab
--docker-username user gitlab autorisé à acceder au registry
--docker-password son mot de passe
--docker-email son email
We will check secret creation :
> kubectl get secret regsecret
NAME TYPE DATA AGE
regsecret kubernetes.io/dockercfg 1 19h
Show details :
> kubectl get secret regsecret --output=yaml
apiVersion: v1
data:
.dockercfg: eyJiXXXXXXteoirutXXXXetusrnXX=
kind: Secret
metadata:
creationTimestamp: 2017-08-07T13:32:09Z
name: regsecret
namespace: default
resourceVersion: "2783"
selfLink: /api/v1/namespaces/default/secrets/regsecret
uid: cfeXXXb7-7b74-XXX-XXX907-4iu8237492
type: kubernetes.io/dockercfg
It’s now possible to use images from your registry directly in your deployment.
Example
apiVersion: apps/v1beta1
kind: Deployment
metadata:
name: test-registry
spec:
replicas: 3
template:
metadata:
labels:
app: my-app
version: v1
spec:
containers:
- name: my-app
image: registry.gitlab.xyz/images/my-app:latest
imagePullPolicy: Always
ports:
- containerPort: 80
imagePullSecrets:
- name: regsecret
See where we call secret :
imagePullSecrets:
- name: regsecret
Enjoy !
