使用API 将容器上载到注册表V2（2.5.1）

问题描述 投票：1回答：1

嗨，我正在尝试使用API​​将docker容器上传到私有docker注册表。

使用docker命令似乎一切正常：

docker pull ubuntu:16.04
docker tag ubuntu:16.04 <PRIVATE-REGISTRY-IP>:5000/ubuntu/16.04
docker push <PRIVATE-REGISTRY-IP>:5000/ubuntu/16.04

我正在尝试使用API​​上传相同的图像，我做了什么：

  • 使用docker save ubuntu:16.04 -o ubuntu.tar导出容器
  • 解开容器文件tar xf ubuntu.tar
  • 用curl上传所有图层
  • 用curl上传清单

好的，阅读the doc，这些图层必须分别用PUTxswpoi获得它们的摘要，并且在完成之后，清单应该也是sha256sum <LAYER-FILE>到注册表

卷曲电话详情:)

PUT

我还尝试使用最小内容生成手动清单，但也从清单PUT中获取错误：

我发现只有一篇文章真正描述了这个，这有用。

Client: Version: 1.12.1 API version: 1.24 Go version: go1.6.2 Git commit: 23cf638 Built: Tue, 27 Sep 2016 12:25:38 +1300 OS/Arch: linux/amd64 Server: Version: 1.12.1 API version: 1.24 Go version: go1.6.2 Git commit: 23cf638 Built: Tue, 27 Sep 2016 12:25:38 +1300 OS/Arch: linux/amd64

本文介绍了使用V1配置和Manifest创建和上传一个图层到谷歌注册表，但它是学习这个概念的良好基础。

如果网站消失，我会把这个概念放下来，所有这些都归功于该文章的作者https://www.danlorenc.com/posts/containers-part-2/。

基本上在创建清单之前，您需要创建一个v1 + json配置，并将其作为blob上传，其中V1 + json配置包含带有内容摘要的层，而不是blob。

github.com/dlorenc

使用配置和层，您可以定义清单：

cat <<EOF > config.json
{
  "architecture": "amd64",
  "config": {
  },
  "history": [
    {
      "created_by": "Bash!"
    }
  ],
  "os": "linux",
  "rootfs": {
    "type": "layers",
    "diff_ids": [
      "sha256:$(gunzip layer.tar.gz --to-stdout | shasum -a 256 | cut -d' ' -f1)"
    ]
  }
}
EOF

现在您可以上传图层：

# We need to know the size and digest of our layer and config:
size=$(wc -c layer.tar.gz | awk '{print $1}')
digest="sha256:$(shasum -a 256 layer.tar.gz | cut -d' ' -f1)"
config_size=$(wc -c config.json | awk '{print $1}')
config_digest="sha256:$(shasum -a 256 config.json | cut -d' ' -f1)"

cat << EOF > manifest.json
{
  "schemaVersion": 2,
  "mediaType": "application/vnd.docker.distribution.manifest.v2+json",
  "config": {
    "mediaType": "application/vnd.docker.container.image.v1+json",
    "size": $config_size,
    "digest": "$config_digest"
  },
  "layers": [
    {
      "mediaType": "application/vnd.docker.image.rootfs.diff.tar.gzip",
      "size": $size,
      "digest": "$digest"
    }
  ]
}
EOF

上传Config，基本上与图层相同的代码：

# Check to see if the layer exists:
returncode=$(curl -w "%{http_code}" \
            -o /dev/null \
            -I http://<PRIVATE-REGISTRY-IP>:5000/v2/ubuntu/blobs/$digest)

if [[ $returncode -ne 200  ]]; then
    # Start the upload and get the location header.
    # The HTTP response seems to include carriage returns, which we need to strip
    location=$(curl -i -X POST \
               http://<PRIVATE-REGISTRY-IP>:5000/v2/ubuntu/blobs/uploads/ \
               -d "" | grep Location | cut -d" " -f2 | tr -d '\r')

    # Do the upload
    curl -X PUT $location\?digest=$digest --data-binary @layer.tar.gz
fi

并通过推送清单标记您的图像：

returncode=$(curl -w "%{http_code}" -o /dev/null \
    -I http://<PRIVATE-REGISTRY-IP>:5000/v2/ubuntu/blobs/$config_digest)

if [[ $returncode -ne 200  ]]; then
    # Start the upload and get the location header.
    # The HTTP response seems to include carriage returns, which we need to strip
    location=$(curl -i -X POST \

    curl -X PUT $location\?digest=$config_digest --data-binary @config.json
fi

备注

  • 示例代码不执行授权。
  • 不适用于curl -X PUT \ http://<PRIVATE-REGISTRY-IP>:5000/v2/ubuntu/manifests/16.04 --data-binary @manifest.json 内部注册表（400无效清单）
  • 需要手动重定向openshift online starter，因为它返回400与blobs gitlab-registry和HEAD的位置标题
