Pranav Salunke de38f2767f install: Updates syntax for training labs parser.
Training labs parser will allow us to automatically parse RST code
to BASH. This BASH code in turn will be invoked by install-guides for
validating the install guides. To provide the correct information to the
parser for generating BASH code, there are a few changes required to the
RST syntax.

Introduces the following changes to RST syntax:

  - `.. end`

    This tag provides information for the parser to stop extracting the
    given block which could be code, file injection or configuration
    file edit.

  - `.. endonly`

    This tag provides information for the parser with the correct
    distro-switch logic for identifying distro-specific code.

    For .. only:: tags, it is better to avoid nesting. If nesting
    is not avoidable then it is preferable to add the .. endonly
    tag to close the outer block immediately.

  - Extra new lines in code-blocks

    Some commands in the code-blocks provides the expected output of the
    given command. This is not a BASH command which we want to run but
    rather some visual niceness for the users. These new lines provides
    the parser information to identify the end of the command. This
    basic logic would be something similar to find '\r\n' which at least
    for python means new empty line.

  - `mysql>`

    Introducing this operator for mysql commands. This could potentially
    be changed to `pgsql>` or similar for other SQL type databases.
    This allows the parser to identify mysql commands and then run
    them in mysql instead of in 'sh' or 'bash'.

  - `.. path`

    Introducing this tag to provide the parser with the information with
    the path of the configuration file. Using the description text for
    the same is not reliable since the description text may not be
    consistent.

This commit should ideally introduce all the syntax changes required for
the parser to convert the code-blocks in here to BASH code. These
changes should have no impact on the HTML output of the RST code.

Create a volume

  1. Source the demo credentials to perform the following steps as a non-administrative project:

    $ . demo-openrc
  2. Create a 1 GB volume:

    $ openstack volume create --size 1 volume1

    +---------------------+--------------------------------------+
  3. After a short time, the volume status should change from creating to available:

    $ openstack volume list
    
    +--------------------------------------+--------------+-----------+------+-------------+
    | ID                                   | Display Name | Status    | Size | Attached to |
    +--------------------------------------+--------------+-----------+------+-------------+
    | a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1      | available |    1 |             |
    +--------------------------------------+--------------+-----------+------+-------------+

Attach the volume to an instance

  1. Attach a volume to an instance:

    $ openstack server add volume INSTANCE_NAME VOLUME_NAME

    Replace INSTANCE_NAME with the name of the instance and VOLUME_NAME with the name of the volume you want to attach to it.

    Example

    Attach the volume1 volume to the provider-instance instance:

    $ openstack server add volume provider-instance volume1

    Note

    This command provides no output.

  2. List volumes:

    $ openstack volume list
    
    +--------------------------------------+--------------+--------+------+--------------------------------------------+
    | ID                                   | Display Name | Status | Size | Attached to                                |
    +--------------------------------------+--------------+--------+------+--------------------------------------------+
    | a1e8be72-a395-4a6f-8e07-856a57c39524 | volume1      | in-use |    1 | Attached to provider-instance on /dev/vdb  |
    +--------------------------------------+--------------+--------+------+--------------------------------------------+
  3. Access your instance using SSH and use the fdisk command to verify presence of the volume as the /dev/vdb block storage device:

    $ sudo fdisk -l
    
    Disk /dev/vda: 1073 MB, 1073741824 bytes
    255 heads, 63 sectors/track, 130 cylinders, total 2097152 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00000000
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/vda1   *       16065     2088449     1036192+  83  Linux
    
    Disk /dev/vdb: 1073 MB, 1073741824 bytes
    16 heads, 63 sectors/track, 2080 cylinders, total 2097152 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00000000
    
    Disk /dev/vdb doesn't contain a valid partition table

    Note

    You must create a file system on the device and mount it to use the volume.
