Discussion:
Since I've been having troubles with installation, I've digged a bit and found out that the permissions inside Kubernetes tarballs changed between 0.16.0 and 0.17.0. I've downloaded both tarballs, extracted them into separate directories and then extracted the Kubernetes server tarballs. This is what I get: I suppose, there has been a concious decision to restrict the world's access to those binaries. However, this breaks the installation routine mentioned above and probably makes life a bit more difficult in several other places. I'd be thankful for a correction if this wasn't intended or a pointer to the appropriate commit it this is legit -- I'd correct the installation.
assigning this to you to decide who the eventual assignee should be :)
Any news on this front? 0.20.1 is still restricted.
Apologies for the issue. It wasn't intentional -- likely an artifact of build scripts being run by different people? I'll check out 0.20.2 as I build it to make sure it has the right perms.
Apologies, but 0.20.2 didn't include fixed permissions. I now understand the issue, : "make release" builds a tarball using the permissions on files in your local git tree. I had "umask 027" set when I cloned, so those in-the-repo files had no world-readable perms. Setting "umask 022" before running "make release" is not enough -- it has to be part of creating the local tree when cloning. I'll update instructions and the next release (20.3 or 21.0) should fix this issue. And longer term, we need to put a bit more effort into releasing from a known-good environment and not rely on a developer's workstation's idiosyncrasies -- sorry this bit you.
I can't repro Trying again a different way, but I don't think the umask before clone should do anything (in particular, umasks aren't "sticky" on files, they're sticky to processes.)
And let's pretend on my personal fork isn't woefully out of date (who uses master on their personal fork? I should really just delete that that thing.) Comment updated.
Ah, I see the problem now.

works fine for the server tar, but the full tar also packages examples, etc., and for that, tar tends to just pick up the permissions of the git tree. Got it.
I'll take this. I'm going to write a script to build official bits, and this is easy enough to fix along the way.
Seems not fixed as of Kubernetes 1.0.7
sorry about that. is doing the 1.1.1 release and has been improving release scripts -- is 1.1.1 good re: permissions?
was not built by .
Reassigning to as release-oncall. Quinton, I can mentor or advise as necessary.
And yeah, is fine: There's no real bug here. There was a process issue that occurred with 1.0.7. We can rebuild the binaries if we need to.
FYI, leaving this issue closed, as per 's comment above. If anyone disagrees, please re-open this issue.
