This switches the docs tests from the `oss-zip` distribution to the `zip` distribution so they have xpack installed and configured with the default basic license. The goal is to be able to merge the `x-pack/docs` directory into the `docs` directory, marking the x-pack docs with some kind of marker. This is the first step in that process. This also enables `-Dtests.distribution` support for the `docs` directory so you can run the tests against the `oss-zip` distribution with something like ``` ./gradlew -p docs check -Dtests.distribution=oss-zip ``` We can set up Jenkins to run both.

== cat nodeattrs
|
|
|
|
The `nodeattrs` command shows custom node attributes.
|
|
For example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_cat/nodeattrs?v
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[s/\?v/\?v&s=node,attr/]
|
|
// Sort the resulting attributes so we can assert on them more easilly
|
|
|
|
Could look like:
|
|
|
|
[source,txt]
|
|
--------------------------------------------------
|
|
node host ip attr value
|
|
...
|
|
node-0 127.0.0.1 127.0.0.1 testattr test
|
|
...
|
|
--------------------------------------------------
|
|
// TESTRESPONSE[s/\.\.\.\n$/\n(.+ xpack\\.installed true\n)?\n/]
|
|
// TESTRESPONSE[s/\.\.\.\n/(.+ ml\\..+\n)*/ _cat]
|
|
// If xpack is not installed then neither ... with match anything
|
|
// If xpack is installed then the first ... contains ml attributes
|
|
// and the second contains xpack.installed=true
|
|
|
|
The first few columns (`node`, `host`, `ip`) give you basic info per node
|
|
and the `attr` and `value` columns give you the custom node attributes,
|
|
one per line.
|
|
|
|

|
|
=== Columns
|
|
|
|
Below is an exhaustive list of the existing headers that can be
|
|
passed to `nodeattrs?h=` to retrieve the relevant details in ordered
|
|
columns. If no headers are specified, then those marked to Appear
|
|
by Default will appear. If any header is specified, then the defaults
|
|
are not used.
|
|
|
|
Aliases can be used in place of the full header name for brevity.
|
|
Columns appear in the order that they are listed below unless a
|
|
different order is specified (e.g., `h=attr,value` versus `h=value,attr`).
|
|
|
|
When specifying headers, the headers are not placed in the output
|
|
by default. To have the headers appear in the output, use verbose
|
|
mode (`v`). The header name will match the supplied value (e.g.,
|
|
`pid` versus `p`). For example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
GET /_cat/nodeattrs?v&h=name,pid,attr,value
|
|
--------------------------------------------------
|
|
// CONSOLE
|
|
// TEST[s/,value/,value&s=node,attr/]
|
|
// Sort the resulting attributes so we can assert on them more easilly
|
|
|
|
Might look like:
|
|
|
|
[source,txt]
|
|
--------------------------------------------------
|
|
name pid attr value
|
|
...
|
|
node-0 19566 testattr test
|
|
...
|
|
--------------------------------------------------
|
|
// TESTRESPONSE[s/19566/\\d*/]
|
|
// TESTRESPONSE[s/\.\.\.\n$/\n(.+ xpack\\.installed true\n)?\n/]
|
|
// TESTRESPONSE[s/\.\.\.\n/(.+ ml\\..+\n)*/ _cat]
|
|
// If xpack is not installed then neither ... with match anything
|
|
// If xpack is installed then the first ... contains ml attributes
|
|
// and the second contains xpack.installed=true
