Arvados

<emyr> what should the permission key file used by keepstore contain ? there doesn't seem to be any mention of this on the keepstore install doc page : http://doc.arvados.org/install/install-keep.html
<brett> emyr: It should contain a single line with a long random alphanumeric string. It should be the same as the blob_signing_key that you set in the API server's config/application.yml.
<brett> There are comments in config/application.default.yml that explain in a little more detail.
<emyr> I've got past that bit. I'd suggest you make a mention of it on the keep install page as people installing it from scratch will just immediately go to the install instructions and expect to have the information there.
<emyr> Now I'm on to the bit about installing the SSO server. The command 'bundle install' doesn't work for me. is there a list of pre-requisites somewhere ? Again it would be handy if there was a link to the pre-reqs from the install documentation.
<brett> emyr: Yeah, I agree, it's sort of a known weak point in our documentation. Can you paste the error you get when you try to run `bundle install`?
<tetron> brett: emyr maybe we could file some tickets on specific things missing from the documentation?
<tomclegg> (hm, is sso-server still in openid-limbo?)
<brett> tomclegg: That's the last update I heard about it.
<tetron> cure is getting coffee then he can answer that
<emyr> initially i just got command not found. I did 'gem install bundler' which enabled the command - this should be mentioned in the docs.
<emyr> anyway, the error I get now is...
<emyr> Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:13:in `<main>' Gem files will remain installed in /var/lib/gems/1.9.1/gems/bcrypt-ruby-3.1.2 for inspection. Results logged to /var
<emyr> happy to go through theis as a guinea pig so you can improve the docs by the way :-D
<tetron> emyr: ah. I think that falls in the category of things that's totally obvious if you're a ruby developer and totally not obvious if you're not
<emyr> yup...not done any ruby
<tomclegg> (might be better off using https://auth.curoverse.com with the ID/secret in arvados/docker/config.yml.example)
<emyr> python, C++, java, perl, tcl, php yep....no ruby :-D
<tetron> emyr: ah, you need to install Ruby 2.1
<emyr> ok. I'll do that. Should I just install the latest ruby from source into /usr/local ?
<emyr> this machine is running ubuntu 12-04 LTS
<tomclegg> emyr: I'd recommend skipping the "install SSO" step and going to "install the API server" at least until @cure comes back with coffee
<tomclegg> emyr: it leads you through installing ruby 2.1, for one thing
<tetron> emyr: http://doc.arvados.org/install/install-api-server.html
<tetron> we should probably have a "prerequisites" page
<tomclegg> that install-api-server page is supposed to have all the prerequisites
<emyr> yep. but coming up with a list can be harder than it seems. At least if you have one it gives you something to keep up-to-date as you get feedback on failed builds

Issues I have come across so-far :

• The documentation referred to the package and executable 'keep' but this had been changed to 'keepstore' Docs are now updated.
• for the SSO install, the command 'bundle install' doesn't work out of the box on a vanilla ubuntu install. Need to install the bundler ruby gem - obvious for a ruby dev but not those without ruby experience. A pre-requisites page along with advice on how to get them installed on typical machines (e.g. out of the box ubuntu LTS) would be handy. We have ubuntu 12-04 at our institution so the ruby is a bit out of date. I will install a later version of ruby from source and carry on with the 'install-api-server' section for now.

Another issue...
When getting the api server up and running, I'm running into the following when doing the database initialization step...

root@host:~/arvados/services/api# RAILS_ENV=development bundle exec rake db:setup
arvados_development already exists
arvados_test already exists
rake aborted!
Refusing to start in development mode with missing configuration.

• blob_signing_key

I can't see any metnion of blob_signing_key in the docs.

now running in to this issue...

http://stackoverflow.com/questions/4368789/error-must-be-owner-of-language-plpgsql

I will remove plpgsql from template1 and see if that allows progress

ran in to various issues with the db setup, possibly due to a partial setup previously that ran into an issue. I dropped databases arvados_development and arvados_test and then redid the rake command which completed without error.
