= Elasticsearch X-Pack

A set of Elastic's commercial plugins for Elasticsearch:

- License
- Security
- Watcher
- Monitoring
- Machine Learning
- Graph

= Setup

You must checkout `x-pack-elasticsearch` and `elasticsearch` with a specific directory structure. The
`elasticsearch` checkout will be used when building `x-pack-elasticsearch`. The structure is:

- /path/to/elastic/elasticsearch
- /path/to/elastic/elasticsearch-extra/x-pack-elasticsearch

== Vault Secret

The build requires a Vault Secret ID. You can use a GitHub token by following these steps:

1. Go to https://github.com/settings/tokens
2. Click *Generate new token*
3. Set permissions to `read:org`
4. Copy the token into `~/.elastic/github.token`
5. Set the token's file permissions to `600`

```
$ mkdir ~/.elastic
$ vi ~/.elastic/github.token
# Add your_token exactly as it is into the file and save it
$ chmod 600 ~/.elastic/github.token
```

If you do not create the token, then you will see something along the lines of this as the failure when trying to build X-Pack:

```
* What went wrong:
Missing ~/.elastic/github.token file or VAULT_SECRET_ID environment variable, needed to authenticate with vault for secrets
```

=== Offline Mode

When running the build in offline mode (`--offline`), it will not required to have the vault secret setup.

== Native Code

**This is mandatory as tests depend on it**

Machine Learning requires platform specific binaries, build from https://github.com/elastic/machine-learning-cpp via CI servers.

The native artifacts are stored in S3. To retrieve them infra's team Vault service is utilized, which 
requires a github token. Please setup a github token as documented: 

https://github.com/elastic/infra/blob/master/docs/vault.md#github-auth

The github token has to be put into ~/.elastic/github.token, while the file rights must be set to 0600.

= Building documentation

The source files in this repository can be included in either the X-Pack Reference or the Elasticsearch Reference. 

NOTE: In 5.5 and later, the Elasticsearch Reference includes X-Pack-specific content when it is built from this repo.

To build the Elasticsearch Reference on your local machine:

* Use the `index.asciidoc` file in the docs/en directory.
* Specify the location of the `elasticsearch/docs` directory with the `--resource` option when you run `build_docs.pl`.

For example:

[source, txt]
-----
./docs/build_docs.pl --doc elasticsearch-extra/x-pack-elasticsearch/docs/en/index.asciidoc 
--resource=elasticsearch/docs --chunk 1
-----

For information about building the X-Pack Reference, see the README in the x-pack repo.

To build a release notes page for the pull requests in this repository:

* Use the dev-tools/xes-release-notes.pl script to pull PRs from the x-pack-elasticsearch repo.  Alternatively, use the dev-tools/xescpp_release_notes.pl script to pull PRs from both the x-pack-elasticsearch and machine-learning-cpp repos.
* Specify the version label for which you want the release notes.
* Redirect the output to a new local file.

NOTE: You must have a personal access token called ~/.github_auth with "repo" scope. Use steps similar to "Vault Secret" to create this file. 

For example:
[source, txt]
-----
./dev-tools/xes_release_notes.pl v5.5.2 > ~/tmp/5.5.2.asciidoc
-----

== Adding Images

When you include an image in the documentation, specify the path relative to the location of the asciidoc file. By convention, we put images in an `images` subdirectory.

For example to insert `watcher-ui-edit-watch.png` in `watcher/limitations.asciidoc`:

. Add an `images` subdirectory to the watcher directory if it doesn't already exist. 
. In `limitations.asciidoc` specify:
+
[source, txt]
-----
 image::images/watcher-ui-edit-watch.png["Editing a watch"]
-----
 
Please note that image names and anchor IDs must be unique within the book, so do not use generic identifiers.
