google gcr.io、k8s.gcr.io 国内镜像

1、首先添加docker官方的国内镜像

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://registry.docker-cn.co"]
}
EOF

2、gcr.io镜像

根据开源项目：

https://github.com/anjia0532/gcr.io_mirror

作者将gcr.io相关镜像pull下来，然后push到docker官方仓库，相关转换语法如下：

语法

gcr.io/namespace/image_name:image_tag 
# 等价于
anjia0532/namespace.image_name:image_tag

# 特别的
k8s.gcr.io/{image}/{tag} <==> gcr.io/google-containers/{image}/{tag} <==> anjia0532/google-containers.{image}/{tag}

批量转换

# replace gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1 to real image
# this will convert gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1 
# to anjia0532/google-containers.federation-controller-manager-arm64:v1.3.1-beta.1 and pull it
# k8s.gcr.io/{image}/{tag} <==> gcr.io/google-containers/{image}/{tag} <==> anjia0532/google-containers.{image}/{tag}

images=$(cat img.txt)
#or 
#images=$(cat <<EOF
# gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1
# gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1
# gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1
#EOF
#)

eval $(echo ${images}|
        sed 's/k8s\.gcr\.io/anjia0532\/google-containers/g;s/gcr\.io/anjia0532/g;s/\//\./g;s/ /\n/g;s/anjia0532\./anjia0532\//g' |
        uniq |
        awk '{print "docker pull "$1";"}'
       )

# this code will retag all of anjia0532's image from local  e.g. anjia0532/google-containers.federation-controller-manager-arm64:v1.3.1-beta.1 
# to gcr.io/google-containers/federation-controller-manager-arm64:v1.3.1-beta.1
# k8s.gcr.io/{image}/{tag} <==> gcr.io/google-containers/{image}/{tag} <==> anjia0532/google-containers.{image}/{tag}

for img in $(docker images --format "{{.Repository}}:{{.Tag}}"| grep "anjia0532"); do
  n=$(echo ${img}| awk -F'[/.:]' '{printf "gcr.io/%s",$2}')
  image=$(echo ${img}| awk -F'[/.:]' '{printf "/%s",$3}')
  tag=$(echo ${img}| awk -F'[:]' '{printf ":%s",$2}')
  docker tag $img "${n}${image}${tag}"
  [[ ${n} == "gcr.io/google-containers" ]] && docker tag $img "k8s.gcr.io${image}${tag}"
done

3、 pull-google-container 工具脚本

为了方便pull container，我们可以编写一个shell脚本辅助：

vim pull-google.sh:

  image=$1
  echo $1
  img=`echo $image | sed 's/k8s\.gcr\.io/anjia0532\/google-containers/g;s/gcr\.io/anjia0532/g;s/\//\./g;s/ /\n/g;s/_/-/g;s/anjia0532\./anjia0532\//g' | uniq | awk '{print ""$1""}'`
  echo "docker pull $img"
  docker pull $img
  echo  "docker tag $img $image"
  docker tag $img $image
~                           

然后放到/usr/local/bin

chmod +x  pull-google.sh && cp  pull-google.sh /usr/local/bin/pull-google-container 

就可以愉快的使用pull-google-container 命令了

pull-google-container gcr.io/google-samples/gb-frontend:v4
gcr.io/google-samples/gb-frontend:v4
docker pull anjia0532/google-samples.gb-frontend:v4
v4: Pulling from anjia0532/google-samples.gb-frontend
Digest: sha256:aaa5b327ef3b4cb705513ab674fa40df66981616950c7de4912a621f9ee03dd4
Status: Image is up to date for anjia0532/google-samples.gb-frontend:v4
docker tag anjia0532/google-samples.gb-frontend:v4 gcr.io/google-samples/gb-frontend:v4
