I want to use pulumi to set up ECS with an image from a private docker registry (GitLab). Is there a way to specify the secret in the container defintion?
I'm trying to set up a new ECS cluster (awsx.ecs.Cluster) with a Service (awsx.ecs.EC2Service) running a Task with a container (awsx.ecs.Container). The image for the container is stored in a Gitlab private docker registry.
In the AWS console I would've created a Task with a container and selected Private repository authentication. This allows setting an arn to a secret in secrets manager containing credentials as described in Private Registry Authentication for Tasks.
I haven't found a way to set this in pulumi though.
then you would need to do it like you normally would in kubernetes.
Create a docker registry secret (set its type to kubernetes.io/dockerconfigjson) and make pod reference that secret, so add imagepullsecrets to pod spec.

In order to deploy an application using docker and a remote registry:
Using docker client, execute docker login so that the credentials will be stored either directly in $HOME/.docker/config.json or on a credential store specified also in $HOME/.docker/config.json. Then use the docker create command to start the application.
In kubernetes, a secret can be generated using the docker registry username and password. Then, the secret can be injected in the helm-chart using imagePullSecret. then, helm install command can instruct kubelet to pull the image inside the created container inside the scheduled pod. To update the image registry, the image name and pull secret can be updated before re-installation.
I have three questions:
How can I set the username and password or inject these credentials for the services in docker-compose without having to run docker login first in each deployment host ? (as in nu
Can I populate a credential store specified in a $HOME/.docker/config.json using docker login command on one machine, then specify the same credential store in $HOME/.docker/config.json of another machine, then use the answer of the previous question to inject or pull the credentials
if the docker daemon checks for the credentials inside the credential stores that is specified in $HOME/.docker/config.json, then what is the use of the helper program ?
I have a private registry at the url registry.lab.example.com where I can push images to from my master node in ocp cluster. When I go about launching a new app referring an image from this private registry, the lookup fails with a error message that the image is not found.
oc new-app --docker-image=registry.lab.example.com/openshift/nginx
My private registry is not even polled to look for the images and that'y why the deployment fails. Is there a way I can add this private registry in the list of to be searched repositories when docker tries to find an image?
There's --add-registry option for docker daemon in RHEL's docker branch (see registry-externally-accessible, check if it's fit to your environment). In addition, you can configure the registry a primary docker source (see pull-through-cache).
Is there anyway to proxy or mirror the following Docker registries with my own Private Docker Registry?
Google Container Registry
AWS EC2 Container Registry
Azure Container Registry
Quay.io
DockerHub
I want to use a Private Registry to store all Docker Images I need.
I want to pull Images without changing the repo/image:tag name when doing a docker pull? For example, with Nexus if I want to do a:
docker pull gcr.io/google_containers/metrics-server-amd64:v0.2.1
I must change the repo name:
docker pull mynexus.mycompany.com/google_containers/metrics-server-amd64:v0.2.1
Is there any docker/kubernetes config that says if someeone does a pull if a gcr.io Image just go to mynexus.mycompany.com instead and use as a pass thru cache.
GCR, ECR, ACR and Quay.io not supported current docker
Try this proxy
https://github.com/rpardini/docker-registry-proxy
https://github.com/rpardini/docker-caching-proxy-multiple-private
In Sonatype Nexus,
create a "docker (proxy)" repository.
create a "docker (group)" repository.
In the group, repository, add both the proxy and any hosted repos
You should now be able to refer to the group repository URL, qualified with your image names and tags, to retrieve any image in any repository that the group can see. You will need to set-up individual proxies for each of GCR, Quay, etc. Also, your image build processes will need to push to the one of your hosted repositories, NOT to the group repository. You push to your hosted, and pull from your group.
I am trying to use Docker + Kubernetes for my application management.
I have installed kubectl, kubeadm, kubelet (got the steps from google docs) for Kubernetes cluster.
Now cluster is having 2 node(1 Master, 1 Child)
I have a customize Dockerfile , how can it use it as a Kubernetes pods ?
If this is not possible,
How to transmit the docker build to the Kubernetes child from master.
You could use a private Docker registriy outside or inside the cluster or work with local (pre-pulled) images.
Outside the cluster you might want to look at these:
Docker registry image
Jfrog Artifactory registry
Sonatype Nexus
Dockerhub private registry
Google private registry
Amazon ECR
Quai.io registry
Azure registry
Inside the cluster you might want to look at the Private Docker Registry in Kubernetes
If you're not interested to use a registry, you could also build the image on every Kubernetes node so that Docker doesn't have to pull it. To avoid that Kubernetes tried to pull anyways you would then have to set the imagePullPolicy of your containers to Never. That's described within the official documentation.
Dockerfiles create images which are used by pods, Kubernetes only uses your created docker image it doesn't build docker images for you. I think what you want to do is:
create an image from your dockerfile by using docker build
send that image to dockerhub using docker push
create a kubernetes deployment that uses your image https://kubernetes.io/docs/user-guide/deployments/
That should get you in the right direction but you will have to read up more :)
I've set up an OpenShift Origin 1.1.3 cluster. Now I'm pulling images from a private registry. This registry is 'insecure'. It has self-signed certificates and credentials to authenticate. I'm able to perform a docker login and to pull the image manually on my node.
The problem is that only that node can access the image. So when I'm scaling my pod (based on that image), all replica's will run on that specific node. Other nodes are not able to pull or use the image.
So I want to create an image-stream for my image:
oc import-image --insecure=true ec2-xxx:5000/image
But: message: you may not have access to the Docker image "ec2-xxx:5000/image"
reason: Unauthorized
I read about creating a secret. I created it:
oc secrets new-dockercfg mysecret --docker-server=ec2-xxx:5000 --docker-username=*** --docker-password=*** --docker-email=any#mail.com
How do I have to add this secret to my image-stream? And is this the right approach?
#cloudnoob his answer helped me a lot.
But the main problem was that I've created my secret in the wrong way.
I saw this after starting the OpenShift master with loglevel 5.
Unable to find a secret to match https://ec2-xxx:5000/v2/test/image/manifests/83
So I had to create my secret with https (it's called insecure with selfsigned certificates but it's using https):
oc secrets new-dockercfg mysecret --docker-server=https://ec2-xxx:5000 --docker-username=*** --docker-password=*** --docker-email=any#mail.com
After this step I had to perform the steps of cloudnoob. Adding the secrets to the service accounts. After that the import is a succes.
Openshift Origin Doc
To use a secret for pulling images for pods, you must add the secret to your service account. The name of the service account in this example should match the name of the service account the pod will use; default is the default service account:
$ oc secrets add serviceaccount/default secrets/ --for=pull
To use a secret for pushing and pulling build images, the secret must be mountable inside of a pod. You can do this by running:
$ oc secrets add serviceaccount/builder secrets/
