      deploy: Make ganeti1 a synnefo backend · 7bdced4c
      Dimitris Aragiorgis authored
      This is done by making True the synnefo option in the ganeti1
      section. This way the VMC component will require some other
      components (Image, GanetiCollectd, ArchipGaneti, etc.) that are
      needless in a regular Ganeti cluster.

      deploy: Refactor fabfile · ac8113ce
      Dimitris Aragiorgis authored
      The fabfile is now responsible to find the target nodes for each
      execution context. It practically gets the corresponding component
      for each role and invokes its setup() method.
      
      To get the execution context for each action we use fabric's execute()
      and update the context based on env.host.
      
      Some things can be done concurrently (setup of each VMC node).
      To do so, we use the fabric's @parallel decorator.
      
      Additionally we support setup of a single component/role on a target
      node or even the execution of a single method of a component.

      deploy: Refactor components module · 3699d1fe
      Dimitris Aragiorgis authored
      Up until now components were simple objects decoupled from fabric
      execution. Their methods were just returning a list of bash commands
      which utils module was executing in the correct context.
      
      This patch changes this rational. Specifically:
      
      A Component() gets initialized with an execution context that is a
      configuration snapshot of the target setup, cluster and node. A
      component implements the following helper methods: check, install,
      prepare, configure, restart, initialize, and test. All those methods
      will be executed on the target node with this order during setup.
      
      Additionally each Component class implements admin_pre, and
      admin_post methods which invoke actions on different components on
      the same execution context before and after installation. For
      example before a backend gets installed, its FQDN must resolve to
      the master floating IP, so we have to run some actions on the ns
      node and after installation we must add it to cyclades (snf-manage
      backend-add on the cyclades node).
      
      Component() inherits ComponentRunner() which practically exports the
      setup() method. This will first check if the required components are
      installed, will install them if not and update the status of target
      node.
      
      ComponentRunner() inherits FabricRunner() which practically wraps
      basic fabric commands (put, get, run) with the correct execution
      environment.
      
      The fabfile practically gets the target nodes for each role from the
      configuration and uses the roles module which knows the
      role-component mapping to get the target component with the proper
      execution context. Then it just invokes the setup() method.
      
      Each component gets initialized with an execution context and uses
      the config module for accessing global wide options. The context
      provides node, cluster, and setup related info.
      
      We introduce some helper decorators that wrap methods of Component
      class and update its execution context (self, self.ctx):
      
      - parse_* executes the wrapped method and parses the output.
        The desired vars (user_id, backend_id, user_uuid, etc.) are
        stored in the execution context and made available to other
        methods.
      
      - update_admin initializes the admin roles (NS, Astakos,
        Cyclades, etc.) of the current context and make them available
        under self.NS, self.ASTAKOS, etc. These have the same execution
        context of the current components besides the target node
        which gets derived from the corresponding config.
      
      - update_cluster_admin initializes the cluster's admin role
        and make it available under self.MASTER.
      
      - run_cmds runs the list of returned commands in the target node
      
      The update_ns() method of NS component gets the
      self.ctx.admin_fqdn and invokes nsupdate accordingly.

      This is used to get the target component for each node.
      It has a role-component mapping and should be used like:

      where the ctx is a Context() with proper node, role, cluster, setup.

      Dimitris Aragiorgis authored
      This module will be used as a common execution context
      just like fabric's env. A context is basically the node, role,
      cluster, and setup that a components gets installed. The new
      Context class is a configuration snapshot for the given context.
      It exports helper methods to get the node's and cluster's info, etc.
      This class is used to initialize the target component class.

      This is used to keep track of the deployment status. The status file
      is kept under the 'state' dir. The check() method is used to find
      conflicting components or the ones that have already been installed.
      The update() method adds an entry in the node's section. If in dry-run
      this file is not written back to permanent storage (kept in memory).

      deploy: Add config module · f6532cfc
      Dimitris Aragiorgis authored
      This module reads the configuration and includes
      several methods for extracting info. It gets
      initialized with the command line arguments.
      
      It reads the DEFAULT section of synnefo, vcluster, and deploy conf
      files and evaluates their options in a sense that once it gets
      imported, one has easy access to generic configuration variables,
      e.g. config.synnefo_user.
      
      On the other hand the setups, nodes, ganeti and packages conf files
      are proper ConfigParser files with sections and default values.
      
      nodes: All info needed for each node.
      ganeti: All info needed for each cluster.
      setups: All role-nodes mappings for each setup and each cluster.
      packages: All special package versions for each OS.
      
      The get_info() helper method gets a node or cluster identifier
      (e.g. node2, ganeti1) and returns a FQDN object with all related
      options as attributes.
      
      The get_package() helper method is used to get the special version
      (if any) of a package.

      To install a minimal Ganeti cluster for QA run:
      
       snf-deploy ganeti-qa
      
      This will create a ganeti cluster. The test instances will resolve on
      the local nameserver. On the client node it clones the official repo
      and installs all required packages required for ganeti development.
      A sample qa json file is uploaded under /tmp.
      
      To run the qa go to the client node and run:
      
       # cd ganeti
       # python ganeti-qa.py /tmp/qa-sample.json --yes-do-it
      
      Note that the installed version in the qa cluster should be the same
      used in the qa source.

      deploy: Extract synnefo's components from ganeti · de81d118
      Dimitris Aragiorgis authored
      The components PithosBackend, Image, GTools, and GanetiCollectd
      are related to Ganeti but used only by Synnefo.
      
      Define new role, named 'snf-ganeti' to include those components and use
      it with the `snf-deploy ganeti` command.
      
      Install ganeti-instance-debootstrap so that we have a working os
      provider.
      
      snf-image takes a lot of time to be configured (curl,
      snf-image-update-helper, wget debian-base image) and is not needed
      for a simple Ganeti cluster (i.e. QA cluster).
      
      Move wget of debian base image to Image component and not nfs.
      In order not to download many times check if it already exists
      in the proper path.

      Merge pull request #28 from cstavr/feature-unicode-handling · 8d477a6d
      Ilias Tsitsimpis authored
      This patch-set fixes a number of issues relative with handling unicode strings.
      These commits try to avoid mixing bytestrings and unicode objects, by decoding
      bytestrings as early as possible (Input) and encoding unicodes as late as
      possible (Ouput). In the API the encoding that is used is always 'UTF-8'. In
      the CLI the encoding that is used is the user's preferred encoding.
      
      Besides unicode issues, this patch-set fixes handling of image metadata
      (Plankton) which are views as HTTP headers. Since, image metadata must be valid
      HTTP headers, metadata keys and values which contain user defined values must
      be properly quoted and unquoted where needed.

      When writing Pithos+ mapfiles with direct I/O enabled Archipelago takes
      care to use properly aligned and sized I/O based on the basic block unit,

      produce the wrong mapfile.
