Kubernetes 镜像源

Kubernetes 镜像问题

Kubernetes 很多都是 Google 提供的地址,在国内很多镜像拉不下来导致服务部署失败,以下列举 Kubernetes 集群部署过程中部署失败的替代方案.

Kubernetes 集群部署

查看需要拉取的镜像:

$ kubeadm config images list
k8s.gcr.io/kube-apiserver:v1.14.1
k8s.gcr.io/kube-controller-manager:v1.14.1
k8s.gcr.io/kube-scheduler:v1.14.1
k8s.gcr.io/kube-proxy:v1.14.1
k8s.gcr.io/pause:3.1
k8s.gcr.io/etcd:3.3.10
k8s.gcr.io/coredns:1.3.1

See Posting Source Code for supported languages

初始化的时候报如下错误:

error execution phase preflight: [preflight] Some fatal errors occurred:
	[ERROR ImagePull]: failed to pull image k8s.gcr.io/kube-apiserver:v1.14.1: output: Error response from daemon: Get https://k8s.gcr.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

先拉取镜像:

docker pull mirrorgooglecontainers/kube-apiserver:v1.14.1
docker pull mirrorgooglecontainers/kube-controller-manager:v1.14.1
docker pull mirrorgooglecontainers/kube-scheduler:v1.14.1
docker pull mirrorgooglecontainers/kube-proxy:v1.14.1
docker pull mirrorgooglecontainers/pause:3.1
docker pull mirrorgooglecontainers/etcd:3.3.10
docker pull coredns/coredns:1.3.1

查看如下:

$ docker images
REPOSITORY                                       TAG                 IMAGE ID            CREATED             SIZE

mirrorgooglecontainers/etcd                      3.2.24              3cab8e1b9802        4 months ago        220MB
mirrorgooglecontainers/pause                     3.1                 da86e6ba6ca1        13 months ago       742kB

分别修改上述镜像的标签:

docker tag mirrorgooglecontainers/kube-apiserver:v1.14.1 k8s.gcr.io/kube-apiserver:v1.14.1
docker tag mirrorgooglecontainers/kube-controller-manager:v1.14.1 k8s.gcr.io/kube-controller-manager:v1.14.1
docker tag mirrorgooglecontainers/kube-scheduler:v1.14.1 k8s.gcr.io/kube-scheduler:v1.14.1
docker tag mirrorgooglecontainers/kube-proxy:v1.14.1 k8s.gcr.io/kube-proxy:v1.14.1
docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1
docker tag mirrorgooglecontainers/etcd:3.3.10 k8s.gcr.io/etcd:3.3.10
docker tag coredns/coredns:1.3.1 k8s.gcr.io/coredns:1.3.1

最后清理:

docker rmi mirrorgooglecontainers/kube-apiserver:v1.14.1
docker rmi mirrorgooglecontainers/kube-controller-manager:v1.14.1
docker rmi mirrorgooglecontainers/kube-scheduler:v1.14.1
docker rmi mirrorgooglecontainers/kube-proxy:v1.14.1
docker rmi mirrorgooglecontainers/pause:3.1
docker rmi mirrorgooglecontainers/etcd:3.3.10
docker rmi coredns/coredns:1.3.1
