Then you have to mount the CA file in some directory in the nodes in the cluster and include that mounted file in a configs section in the registries.yaml file .

In order to push to this registry, you will need to make it accessible as described in the next section. Once your registry is up and running, we will need to add it to your registries.yaml configuration file. Finally, you have to connect the registry network to the k3d cluster network: docker network connect k3d-k3s-default registry.localhost . And then you can test your local registry . Pushing to your local registry address \u00b6 As per the guide above, the registry will be available at registry.localhost:5000 .

We will verify these two things for a local registry (located at registry.localhost:5000 ) running in your development machine. Things would be basically the same for checking an external registry, but some additional configuration could be necessary in your local machine when using an authenticated or secure registry (please refer to Docker\u2019s documentation for this).

Then you have to mount the CA file in some directory in the nodes in the cluster and include that mounted file in a configs section in the registries.yaml file . For example, if we mount the CA file in /etc/ssl/certs/my-company-root.pem , the registries.yaml will look like: mirrors : my.company.registry : endpoint : - https://my.company.registry configs : my.company.registry : tls : # we will mount \"my-company-root.pem\" in the /etc/ssl/certs/ directory. ca_file : \"/etc/ssl/certs/my-company-root.pem\" Finally, we can create the cluster, mounting the CA file in the path we specified in ca_file : k3d cluster create --volume \" ${ HOME } /.k3d/my-registries.yaml:/etc/rancher/k3s/registries.yaml\" --volume \" ${ HOME } /.k3d/my-company-root.pem:/etc/ssl/certs/my-company-root.pem\" Using a local registry \u00b6 Using the k3d registry \u00b6 Not ported yet The k3d-managed registry has not yet been ported from v1.x to v3.x Using your own local registry \u00b6 You can start your own local registry it with some docker commands, like: docker volume create local_registry docker container run -d --name registry.localhost -v local_registry:/var/lib/registry --restart always -p 5000 :5000 registry:2 These commands will start your registry in registry.localhost:5000 . In order to push to this registry, you will need to make it accessible as described in the next section. Once your registry is up and running, we will need to add it to your registries.yaml configuration file. Finally, you have to connect the registry network to the k3d cluster network: docker network connect k3d-k3s-default registry.localhost . And then you can test your local registry . Pushing to your local registry address \u00b6 As per the guide above, the registry will be available at registry.localhost:5000 .

We will verify these two things for a local registry (located at registry.localhost:5000 ) running in your development machine. Things would be basically the same for checking an external registry, but some additional configuration could be necessary in your local machine when using an authenticated or secure registry (please refer to Docker\u2019s documentation for this).

Things would be basically the same for checking an external registry, but some additional configuration could be necessary in your local machine when using an authenticated or secure registry (please refer to Docker\u2019s documentation for this). First, we can download some image (like nginx ) and push it to our local registry with: ```shell script docker pull nginx:latest docker tag nginx:latest registry.localhost:5000/nginx:latest docker push registry.localhost:5000/nginx:latest Then we can deploy a pod referencing this image to your cluster: ```shell script cat <<EOF | kubectl apply -f - apiVersion: apps/v1 kind: Deployment metadata: name: nginx-test-registry labels: app: nginx-test-registry spec: replicas: 1 selector: matchLabels: app: nginx-test-registry template: metadata: labels: app: nginx-test-registry spec: containers: - name: nginx-test-registry image: registry.localhost:5000/nginx:latest ports: - containerPort: 80 EOF Then you should check that the pod is running with kubectl get pods -l \"app=nginx-test-registry\" .","title":"Testing your registry"},{"location":"usage/guides/registries/#configuring-registries-for-k3s-v091","text":"k3s servers below v0.9.1 do not recognize the registries.yaml file as described in the in the beginning, so you will need to embed the contents of that file in a containerd configuration file. You will have to create your own containerd configuration file at some well-known path like ${HOME}/.k3d/config.toml.tmpl , like this: # Original section: no changes [plugins.opt] path = \"{{ .NodeConfig.Containerd.Opt }}\" [plugins.cri] stream_server_address = \"{{ .NodeConfig.AgentConfig.NodeName }}\" stream_server_port = \"10010\" {{- if .IsRunningInUserNS }} disable_cgroup = true disable_apparmor = true restrict_oom_score_adj = true {{ end -}} {{- if .NodeConfig.AgentConfig.PauseImage }} sandbox_image = \"{{ .NodeConfig.AgentConfig.PauseImage }}\" {{ end -}} {{- if not .NodeConfig.NoFlannel }} [plugins.cri.cni] bin_dir = \"{{ .NodeConfig.AgentConfig.CNIBinDir }}\" conf_dir = \"{{ .NodeConfig.AgentConfig.CNIConfDir }}\" {{ end -}} # Added section: additional registries and the endpoints [plugins.cri.registry.mirrors] [plugins.cri.registry.mirrors.\" registry.localhost:5000 \"] endpoint = [\"http:// registry.localhost:5000 \"] and then mount it at /var/lib/rancher/k3s/agent/etc/containerd/config.toml.tmpl (where containerd in your k3d nodes will load it) when creating the k3d cluster: k3d cluster create mycluster \\ --volume ${ HOME } /.k3d/config.toml.tmpl:/var/lib/rancher/k3s/agent/etc/containerd/config.toml.tmpl","title":"Configuring registries for k3s &lt;= v0.9.1"}]}
