  when we use K8s to build clusters, there is always a hurdle ahead: Google Container Image (gcr.io). K8s, as the son of google, has no reason not to use the google mirror library. The default container of yaml in the cluster configuration file needs to be pulled from gcr.io. However? In China, we have to face google hard, but fortunately we can still use docker hub. In order to successfully build a k8s cluster, we must solve the immediate problems. I provide two ideas for reference only:

1. Agent. The question of the agent will not be mentioned, and the agent will be installed directly after it is completed. A lot of blog are written on the Internet, and so do mine. But you need to pay attention to one problem: do not proxy your own cluster network segment, pod network segment.

two。 If you convert an image in gcr.io into an image in docker hub, you can download it locally and use tag to become a container in yaml requirements, or you can directly change the image in yaml to docker hub image.

 -search for relevant images on docker hub. Someone must have made the conversion. Make sure the tag is consistent.

 -automate building docker images, refer to building docker automatically using github

 -download the mirror agent created by others directly. Thanks to Anjia, Anjia blog, Anjia github author successfully synchronized all gcr.io images to docker hub by using github + travis ci + docker hub. The usage also refers to his blog.

Although   has explained how to use it on his official blog, he later made a slight modification and only mentioned it on github, and he has no additional comments on his blog, please pay attention.

The specific changes in   are as follows:

K8s.gcr.io/ {image} / {tag} gcr.io/google-containers/ {image} / {tag} anjia0532/google-containers. {image} / {tag}

  gives an example:

Docker pull k8s.gcr.io/federation-controller-manager-arm64:v1.3.1-beta.1eq (equivalent to) docker pull anjia0532/google-containers.federation-controller-manager-arm64:v1.3.1-beta.1
