Re: unauthorized trying to deploy docker container



Thanks Dan. However I sent a subsequent message saying that there was an error in the URL. I think the message is misleading though as it should trigger a 404 Not Found error and not an Unauthorized one.

I'm trying to deploy a couchdb container on openshift, and have created 3 yaml files to this end:

a persistent volume
a persistent volume claim
a deployment config

However, I'm getting the following error upon deployment

Failed to pull image "

docker.io/centos/klaemo/couchdb sha256:d33822ecaae2e6247243b24c5c72c525714d77b904105f71679fbad04756bc96
": unauthorized: access to the requested resource is not authorized

The container is hosted on docker's public registry so wondering what this message means...

​I tried pulling that image myself with `docker pull` and got the same error, which means access to the image requires docker hub authentication. You need to create a secret in OpenShift which contains the pull credentials and then reference that secret in the pod defined in your deploymentConfig. Here's some more information about image pull secrets in Kubernetes and OpenShift:

https://github.com/kubernetes/kubernetes/blob/master/docs/user-guide/images.md#specifying-imagepullsecrets-on-a-pod
https://docs.openshift.org/latest/dev_guide/image_pull_secrets.html

If that's not enough to get you moving, please reach out!
