      Fix ctl node reboot races on Liberty/Ubuntu 15.10. · 74df028a
      David Johnson authored
      Reboots of the ctl node for the Liberty version would result in
      failures to startup mysql, and this renders all openstack services
      inoperable.
      
      Recall that in the common case (because we have many testbeds whose
      nodes only have one expt interface), we setup the openstack mgmt lan as
      a VPN over the control net between all the nodes, served from the nm
      node.
      
      Well, mysql binds to and listens on the ip addr of the mgmt net device,
      and when the ctl node is rebooted, mysql starts long before openvpn can
      bring up the vpn client net device.  Moreover, rabbitmq would fail to
      start for the same reason, and rabbitmq is the AMQP messaging service
      that underlies all openstack RPC.
      
      For various reasons, it's not sufficient to just make the mysql
      initscript (which on 15.10 is still legacy LSB!) depend on the openvpn
      legacy LSB initscript.
      
      So I wrote a little initcript (embedded in setup-controller.sh) that
      spins in a sleep 1; loop, looking for the mgmt net to get its known IP
      from the openvpn client.  It has reverse dependency on mysql, so it runs
      to completion before mysql starts.
      
      Then, we had to handle the rabbitmq case... but rabbitmq has a modern
      systemd unit file, not an LSB initscript.  So I wrote a systemd unit
      file that invokes my mgmt net LSB initscript to wait for the mgmt net
      IP... and that has a reverse dep on rabbitmq-server.service.
      
      Now all is good.  mysql and rabbitmq-server are certainly blocked for a
      few extra seconds, while the VPN comes up, but all the openstack
      services themselves are written defensively to handle RPC server
      disconnects, or database disconnects (doh).

      Add a very simple extension mechanism. · 0e98185b
      David Johnson authored
      User has to include a tarball containing a single dir which in turn
      contains a script called setup.sh .  This tarball must be installed into
      /tmp/setup/ext .  Minimal, but who cares, it works for now.

      Add Liberty support and configurable Keystone API version support. · 0dd7c424
      David Johnson authored
      Add Liberty support.
      
      Add keystone v3 support.  Now you can choose which version of keystone
      to run... all combinations tested exception Juno with v3.
      
      Make node type and link speed configurable.
      
      Make token and session timeouts much longer by default (so people don't
      get logged out so quickly), but also configurable.
      
      Keystone is now served by WSGI through Apache on Kilo and Liberty.
      
      Memcached keystone token caching is disabled for now; it causes
      intermittent problems; so using SQL for now.
      
      Add localhost to /etc/hosts file.  This doesn't cause problems anymore,
      if it ever did.
      
      We now use the `openstack' CLI command for >= Kilo, instead of the
      per-service client CLI tools.
      
      Stick with ovs agent even in Liberty -- even though the default is now
      linuxbridge, it seems.
      
      In general, get rid of nearly all the rest of the cat <<EOF ... EOF
      stuff and replace it with crudini --set/--del.  A touch slower, but much
      cleaner.
      
      Also in general, improve the Kilo support so that it more closely
      matches the docs.

      Support dynamic addition/deletion of compute nodes. · 1dc78db1
      David Johnson authored
      Also, adds a geni-lib script that generates an rspec instead of printing
      it (although print still works at portal) and generates input for
      CM::AddNodes() when requested.  This generator is stateful; it tries
      to avoid generating new nodes with previously-used IPs or client_ids;
      thus it is a separate object.  It is designed so that it can be imported
      into a script, and the importing script can look for special
      DYNSLICE_GENERATOR variables to use its rspec foo to create a slice and
      add nodes in some semantic way.

      Make package installation optional, and separate install/upgrade. · b2634d01
      David Johnson authored
      Quit trying to apt-get packages if they're installed, unless the
      user selects the new DO_APT_UPGRADE option.  Always install was nice
      in the beginning, but it is no longer the best use case, and it can
      cause uncertainty when failures happen (i.e., if new versions of
      packages get installed that the scripts can't handle).  So now there
      are three apt options in the scripts and in the geni-lib script:
      
      DO_APT_UPDATE -- updates the apt cache (often hard to do pkg
        install/upgrade if the cache is out of date); defaults to 1
      DO_APT_INSTALL -- if this is set 0, we don't install *anything*
        other than critical deps (think python-m2crypto); defaults to 1
      DO_APT_UPGRADE -- if this is set 1, we always run apt-get install
        to either install and/or upgrade OpenStack packages and deps.
        The big change is that this now defaults to 0 -- so packages are
        not upgraded from their current versions if they exist.

      A nasty hack to get pubkeys into Openstack "portably". · 6def427b
      David Johnson authored
      This is really, really ugly.  So, keystone and nova don't offer us a way to
      upload keypairs on behalf of another user.  Recall, we're using the adminapi
      account to do all this setup, because we don't know the admin password.  So,
      the below code adds all the keys as 'adminapi', then we dump the sql, do some
      sed magic on it to get rid of the primary key and change the user_id to the
      real admin user_id, then we insert those rows, then we cleanup the lint.  By
      doing it this way, we eliminate our dependency on the SQL format and column
      names and semantics.  We make two assumptions: 1) that there is only one field
      that has integer values, and 2) the only field that is an exception to #1 is
      called 'deleted' and we just set those all to 0 after we jack the whacked sql
      in.  Ugh, it's worse than I hoped, but whatever.
      
      This is one of the sickest one-liners I've ever come up with, but it
      works like a charm!

      Serial console support. · f905c8e7
      David Johnson authored
      Openstack doesn't yet have 1) serial console client builtin to
      dashboard, nor 2) serial console log + r/w serial console access.
      
      So right now, you have to choose if you want to enable r/w console
      access via CLI client, or if you want to be able to view serial logs in
      the dashboard web UI; default is the latter (logs).
      
      If you enable r/w consoles, we download a simple websocket console
      client, setup a little frontend script, so users can type
      
        $ /root/setup/novaconsole.sh <instancename>
      
      and get to the console.  Escape is ~.  In addition to the console CLI
      tool, we have to grab the latest version of the python websocket
      library, cause the one in Ubuntu 15.04 is horribly out of date and
      doesn't seem to support binary/base64 websockets, which the console CLI
      tool requires (as does the server).

      Lots of new features, especially drastically improved network config. · a9265ea7
      David Johnson authored
      Setup several kinds of networks: tunnels, flat networks, flat networks
      multiplexed via vlans over physical networks (where openstack doesn't
      manage the vlan ids), and real vlan networks (where openstack *does*
      manage the vlan ids).  Tunnels always go over the first flat data net.
      
      Be very flexible in terms of assigning IPs; generate them ourselves
      if they dind't come to us, or if user wants to use our generated ones.
      I tried to be smart (enough) with this.
      
      Setup VNC-based consoles on x86-64; working in dashboard.
      
      Don't put plaintext admin password in profile anymore; instead, expect
      a hash of the admin password.  Replace the temp admin password in the
      keystone database with the hash we get.  But, since the CLI tools
      all require real user auth, setup a secondary 'adminapi' account
      that is a real admin, and use that to see admin-openrc.sh for CLI
      tools, and for all our configuration, and places where the services
      use a real admin account to auth.  Also, push the admin password
      hash all the way into our instance images.
