= 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.

= Build

- Run unit tests:
+
[source, txt]
-----
gradle clean test

- Run all tests:
+
[source, txt]
-----
gradle clean check
-----

- Run integration tests:
+
[source, txt]
-----
gradle clean integTest
-----

= Building documentation

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

NOTE: In 5.4 and later, the Elasticsearch Reference includes X-Pack-specific
content that is pulled from this repo.

To build the Elasticsearch Reference on your local machine, use the `docbldes` 
or `docbldesx` build commands defined in
https://github.com/elastic/docs/blob/master/doc_build_aliases.sh

== 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.
