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.

Verify operation
We recommend that you verify NTP synchronization before proceeding further. Some nodes, particularly those that reference the controller node, can take several minutes to synchronize.
Run this command on the controller node:
# chronyc sources 210 Number of sources = 2 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^- 192.0.2.11 2 7 12 137 -2814us[-3000us] +/- 43ms ^* 192.0.2.12 2 6 177 46 +17us[ -23us] +/- 68msContents in the Name/IP address column should indicate the hostname or IP address of one or more NTP servers. Contents in the S column should indicate * for the server to which the NTP service is currently synchronized.
Run the same command on all other nodes:
# chronyc sources 210 Number of sources = 1 MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* controller 3 9 377 421 +15us[ -87us] +/- 15msContents in the Name/IP address column should indicate the hostname of the controller node.
