Set an imagePullSecret as the default for all Pods and Deployments. Image: /myregistry/myimageįor more information on configuring Pods to connect to private registries, consult the Kubernetes documentation. If you used the doctl-based instructions, use registry- instead. In the previous control panel-based example, the secret was named do-registry, so that name is also used here. In the Deployment spec, provide the name of the imagePullSecrets. Set an imagePullSecret on a per-Pod or per-Deployment basis.
Reference the secret you just uploaded as an imagePullSecrets. from-file=.dockerconfigjson=docker-config.json \ Here, we’ve named the secret do-registry: kubectl create secret generic do-registry \ Once you have the credentials on your machine, upload them to your cluster as a secret.

Then, click Download Docker Credentials to download the credentials as a JSON file. To download credentials from the control panel, navigate to the registry page. Obtain credentials from the control panel and upload them manually to the cluster.
Use the registry kubernetes-manifest command to download the credentials for your registry and upload them to your cluster as a secret: doctl registry kubernetes-manifest | kubectl apply -f. Upload the credentials of your registry to your DigitalOcean Kubernetes cluster. To create a secret using kubectl and specify it as an imagePullSecrets: Option 2: Manually Create and Reference Secrets as imagePullSecrets For more information, consult the Kubernetes documentation. To do so, add imagePullSecrets to the service account or workload. You can also use the generated secrets with the other service accounts or for a specific workload. Namespace: all namespaces other than kube-system Once this secret is created, DOKS internally copies the secret data to all other namespaces as shown below: The secret is created in the kube-system namespace of the Kubernetes cluster. To add or remove secrets from the namespaces, click Edit. If you want to use the generated secrets as imagePullSecrets for a specific workload or other service accounts, see Using the Generated Secrets. From then on, you only need to configure the container image name in your workloads. The default service account in each of those namespaces is updated to include the secret in its image pull secret. Once the secret is added to all the namespaces for the selected Kubernetes clusters, the control panel displays the namespaces which have the secret associated with them.
#HOW TO USE DOCKER AND KUBERNETES UPGRADE#
Upgrade your cluster version to continue with the integration. The control panel displays an error message if the control plane of the cluster is unavailable or the version of the cluster is not compatible with the registry integration. Select the clusters you wish to add and click Save.
In the DigitalOcean Kubernetes integration section, click Edit to display the available Kubernetes clusters. Visit the registry page and click the Settings tab.

#HOW TO USE DOCKER AND KUBERNETES PATCH#
Only the latest Kubernetes patch versions, 1.19+, can be integrated with the registry. This generates a secret, adds it to all the namespaces in the cluster and updates the default service account to include the secret, allowing you to pull images from the registry. In the control panel, you can select the Kubernetes clusters to use with your registry. Option 1: Adding Secret to All Namespaces in Kubernetes Clusters (Recommended) Using kubectl: Manually create secrets using kubectl and then specify them as imagePullSecrets for your Kubernetes clusters.Provides 1-click integration of the registry with DigitalOcean Kubernetes clusters and allows you to use images from the registry in your Kubernetes workloads. In the control panel: This is the recommended option.You can integrate DigitalOcean Container Registry with DigitalOcean Kubernetes using one of the following options: Integrate Your Registry with DigitalOcean Kubernetes Cluster You can then use the docker tag command to tag your image with the fully qualified destination path, and docker push to upload it: docker tag // For example: docker login -u ZDRhYzzzz -p ZDRhYzzzz
#HOW TO USE DOCKER AND KUBERNETES PASSWORD#
If you’re in an environment that doesn’t have doctl or want to use an existing API token, you can simulate what doctl registry login does by using an API token string as the username and password when calling docker login. This can be revoked at any time by navigating to API in the DigitalOcean control panel. Under the hood, this generates a DigitalOcean token that grants docker access to your account.
