 1 | # Description
 2 | Copy-Paste Ready™ how-to for using private [Gitlab Container Registry](https://docs.gitlab.com/ce/user/project/container_registry.html) with [Kubernetes](https://kubernetes.io).

 5 | #### Copy and edit example env file accordingly
 6 | ```bash
 7 | cp dockercfg.env.example dockercfg.env
 8 | ```
 9 | 
10 | #### Export variables from dockercfg.env
11 | ```bash
12 | eval $(cat dockercfg.env)
13 | ```
14 | 
15 | #### Export additional variables
16 | ```bash
17 | export REGISTRY_NAME=`echo $DOCKER_REGISTRY_SERVER | sed -e 's/^http:\/\///g' -e 's/^https:\/\///g'`
18 | export DOCKER_IMAGE_FULL_PATH=$REGISTRY_NAME/$DOCKER_IMAGE_PATH
19 | ```
20 | 
21 | #### Create secret in the Kubernetes Cluster
22 | ```bash
23 | kubectl create secret docker-registry gitlab-registry \
24 |   --docker-server=$DOCKER_REGISTRY_SERVER \
25 |   --docker-username=$DOCKER_USER \
26 |   --docker-password=$DOCKER_PASSWORD \
27 |   --docker-email=$DOCKER_EMAIL
28 | ```
29 | 
30 | #### Test
31 | ```bash
32 | cat <<EOF | kubectl apply -f -
33 | apiVersion: v1
34 | kind: Pod
35 | metadata:
36 |   name: foo
37 | spec:
38 |   containers:
39 |     - name: foo
40 |       image: $DOCKER_IMAGE_FULL_PATH
41 |       imagePullPolicy: Always
42 |   imagePullSecrets:
43 |     - name: gitlab-registry
44 | EOF
45 | ```
46 | 
47 | #### Check if the image was pulled successfully
48 | ```bash
49 | kubectl describe po/foo | grep -i pull
50 | ```
51 | 
52 | ### Cleanup
53 | #### Remove pod
54 | ```bash
55 | kubectl delete po/foo
56 | ```
57 | #### Remove file with environment variables
58 | ```bash
59 | rm dockercfg.env
60 | ```
61 | #### Unset environment variables
62 | ```bash
63 | unset DOCKER_REGISTRY_SERVER
64 | unset DOCKER_USER
65 | unset DOCKER_EMAIL
66 | unset DOCKER_PASSWORD
67 | unset DOCKER_IMAGE_PATH
68 | unset REGISTRY_NAME
69 | unset DOCKER_IMAGE_FULL_PATH
70 | ```
71 | 
72 | ✅ Sharing the secret across multiple Kubernetes namespaces 🎉
73 | ```bash
74 | export NAMESPACE=gitlab
75 | kubectl get secret gitlab-registry -o yaml \
76 |   | sed "s/default/$NAMESPACE/g" \
77 |   | kubectl -n $NAMESPACE create -f -
78 | ```
