我正在尝试设置私有Docker Registry并将图像保存到AWS S3实例。注册表似乎工作正常 - 它启动正常,我可以通过https进行身份验证。我遇到的问题是我收到了一个保存到S3的错误,因此我假设S3 IAM策略存在一些权限问题。
docker run
命令如下所示:
docker run -p 443:5000 \
--link redis:redis \
-e REGISTRY_STORAGE=s3 \
-e REGISTRY_STORAGE_S3_BUCKET=my-docker-registry \
-e REGISTRY_STORAGE_S3_ACCESSKEY=**** \
-e REGISTRY_STORAGE_S3_SECRETKEY=**** \
-e REGISTRY_STORAGE_S3_REGION=us-east-1 \
-v `pwd`/auth:/auth \
-e REGISTRY_AUTH=htpasswd \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
-v `pwd`/certs:/certs \
-e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/my.com_chain.crt \
-e REGISTRY_HTTP_TLS_KEY=/certs/my.com.key \
-e REGISTRY_STORAGE_CACHE_BLOBDESCRIPTOR=redis \
-e REGISTRY_REDIS_ADDR=redis:6379 \
registry:2.5
S3 IAM政策如下所示:
{
"Version":"2012-10-17",
"Statement":[
{
"Effect":"Allow",
"Action":[
"s3:ListAllMyBuckets"
],
"Resource":"arn:aws:s3:::*"
},
{
"Effect":"Allow",
"Action":[
"s3:ListBucket",
"s3:GetBucketLocation"
],
"Resource":"arn:aws:s3:::my-docker-registry"
},
{
"Effect":"Allow",
"Action":[
"s3:PutObject",
"s3:GetObject",
"s3:DeleteObject",
"s3:ListMultipartUploadParts",
"s3:AbortMultipartUpload"
],
"Resource":"arn:aws:s3:::my-docker-registry/*"
}
]
}
错误日志条目是:
level=error msg="error resolving upload: s3aws: AccessDenied: Access Denied\n\tstatus code: 403, request id: 2B224..." auth.user.name=my-user go.version=go1.6.3 http.request.host=my.domain.com http.request.id=13b79c07-... http.request.method=PATCH http.request.remoteaddr="xx.xx.xx.xx:41392" http.request.uri="/v2/my-test/blobs/uploads/467d94ea-2a77...?_state=zQd-..." http.request.useragent="docker/1.12.0 go/go1.6.3 git-commit/8eab123 kernel/4.4.15-moby os/linux arch/amd64 UpstreamClient(Docker-Client/1.12.0 \\(darwin\\))" instance.id=8a8db6f1-8fe4 vars.name=my-test vars.uuid=467d94ea-2a77 version=v2.5.0
我在其他应用中使用了类似的文件上传策略,所以我不确定问题出在哪里。我需要在IAM策略中更改哪些内容以允许注册表保存到S3存储桶?
答案 0 :(得分:1)
请检查S3 IAM角色是否已分配给正在使用其访问密钥的IAM用户。您还可以将此角色分配给EC2实例,并避免使用此访问密钥。
