使用API v2将图像上传到Docker Registry时出错
我正尝试使用以下API将Docker镜像（tarball）上传到私人Dockerregistry中。 我正在按照这里的文档： http : //docs.docker.com/registry/spec/api/
第1步：启动上传并获取位置URL
$ curl -v -X POST http://localhost:5000/v2/hello-world/blobs/uploads/ * About to connect() to localhost port 5000 (#0) * Trying ::1... * Connected to localhost (::1) port 5000 (#0) > POST /v2/hello-world/blobs/uploads/ HTTP/1.1 > User-Agent: curl/7.29.0 > Host: localhost:5000 > Accept: */* > < HTTP/1.1 202 Accepted < Content-Length: 0 < Docker-Distribution-Api-Version: registry/2.0 < Docker-Upload-Uuid: dd319793-f017-45b3-afe4-c8102363a8df < Location: http://localhost:5000/v2/hello-world/blobs/uploads/dd319793-f017-45b3-afe4-c8102363a8df?_state=SB2605fFM_7KNkYTHjVrVQVT62dufwXNTw9QzO2_aRR7Ik5hbWUiOiJoZWxsby13b3JsZCIsIlVVSUQiOiJkZDMxOTc5My1mMDE3LTQ1YjMtYWZlNC1jODEwMjM2M2E4ZGYiLCJPZmZzZXQiOjAsIlN0YXJ0ZWRBdCI6IjIwMTUtMTAtMjdUMjI6MjU6MjEuMTM0MTI5MDNaIn0%3D < Range: 0-0 < Date: Tue, 27 Oct 2015 22:25:21 GMT < Content-Type: text/plain; charset=utf-8 < * Connection #0 to host localhost left intact 第2步：使用位置URL上传实际的Docker镜像
$ curl -v -H "Content-type: application/octet-stream" -H "Content-Length: 13824" --data-binary @/tmp/hello-world.tar -X PUT -L "http://localhost:5000/v2/hello-world/blobs/uploads/dd319793-f017-45b3-afe4-c8102363a8df?_state=SB2605fFM_7KNkYTHjVrVQVT62dufwXNTw9QzO2_aRR7Ik5hbWUiOiJoZWxsby13b3JsZCIsIlVVSUQiOiJkZDMxOTc5My1mMDE3LTQ1YjMtYWZlNC1jODEwMjM2M2E4ZGYiLCJPZmZzZXQiOjAsIlN0YXJ0ZWRBdCI6IjIwMTUtMTAtMjdUMjI6MjU6MjEuMTM0MTI5MDNaIn0%3D&digest=tarsum.v2+sha256:97bbb955c700a6414fd48ae147986e9b42c0508c8a766cea61e7e3badf0f7dde" * About to connect() to localhost port 5000 (#0) * Trying ::1... * Connected to localhost (::1) port 5000 (#0) > PUT /v2/hello-world/blobs/uploads/dd319793-f017-45b3-afe4-c8102363a8df?_state=SB2605fFM_7KNkYTHjVrVQVT62dufwXNTw9QzO2_aRR7Ik5hbWUiOiJoZWxsby13b3JsZCIsIlVVSUQiOiJkZDMxOTc5My1mMDE3LTQ1YjMtYWZlNC1jODEwMjM2M2E4ZGYiLCJPZmZzZXQiOjAsIlN0YXJ0ZWRBdCI6IjIwMTUtMTAtMjdUMjI6MjU6MjEuMTM0MTI5MDNaIn0%3D&digest=tarsum.v2+sha256:97bbb955c700a6414fd48ae147986e9b42c0508c8a766cea61e7e3badf0f7dde HTTP/1.1 > User-Agent: curl/7.29.0 > Host: localhost:5000 > Accept: */* > Content-type: application/octet-stream > Content-Length: 13824 > Expect: 100-continue > * Done waiting for 100-continue < HTTP/1.1 400 Bad Request < Content-Type: application/json; charset=utf-8 < Docker-Distribution-Api-Version: registry/2.0 < Date: Tue, 27 Oct 2015 22:29:02 GMT < Content-Length: 131 * HTTP error before end of send, stop sending < {"errors":[{"code":"DIGEST_INVALID","message":"provided digest did not match uploaded content","detail":"digest parsing failed"}]} * Closing connection 0
另外，我使用sha256sum如下：
$ sha256sum /tmp/hello-world.tar 97bbb955c700a6414fd48ae147986e9b42c0508c8a766cea61e7e3badf0f7dde /tmp/hello-world.tar
我在这里可能做错了什么？ 如何解决DIGEST_INVALID错误？
这是一个简单的例子，应该让你走上正轨：
local reponame=foo/bar local uploadURL local numBytes=10000000 # 10 Megabytes uploadURL=$(curl -siL -X POST "https://registrydomain/v2/$reponame/blobs/uploads/" | grep 'Location:' | cut -d ' ' -f 2 | tr -d '[:space:]') blobDigest="sha256:$(head -c $numBytes /dev/urandom | tee upload.tmp | shasum -a 256 | cut -d ' ' -f 1)" echo "Uploading Blob of 10 Random Megabytes" time curl -T upload.tmp --progress-bar "$uploadURL&digest=$blobDigest" > /dev/null
