@diasdavid the js-ipfs-api test failures look like an issue on your end. Could you confirm and let me know when there is a fix?

[whyrusleeping]

the docker thing needs fixing too, fun.

@whyrusleeping the error is:

Because the key we selected to get on tests was Identity, see:

https://github.com/ipfs/interface-ipfs-core/blob/master/src/config.js#L37-L43

I can update the tests to use some other key, is this decision final with regards to not being able to access Identity from the API? How does the go CLI do it then? Some special whitelisting for go-ipfs cli?

[whyrusleeping]

@diasdavid yeah, you can't access anything containing the private key via the api in any way (including the CLI). You could use identity.peerID if you wanted
