bosh-davcli

A CLI utility the BOSH Agent uses for accessing the DAV blobstore.

Inside stemcells this binary is on the PATH as bosh-blobstore-dav.

To update dependencies, use gvt update. Here is a typical invocation to update the bosh-utils dependency:

gvt update github.com/cloudfoundry/bosh-utils

You can run the unit test with ginkgo as follows.

ginkgo -r -race -progress -mod vendor .

The command sign generates a pre-signed url for a specific object, action and duration:

bosh-davcli <objectID> <action: get|put> <duration>

The request will be signed using HMAC-SHA256 with a secret provided in configuration.

The HMAC format is: <HTTP Verb><Object ID><Unix timestamp of the signature time><Unix timestamp of the expiration time>

The generated URL will be of format:

https://blobstore.url/signed/object-id?st=HMACSignatureHash&ts=GenerationTimestamp&e=ExpirationTimestamp
