AWS supports the creation and use of credentials that are only valid for a
fixed period of time. These credentials comprise three parts: the usual access
key and secret key, together with a session token. This commit adds support for
these three-part credentials to the EC2 discovery plugin and the S3 repository
plugin.
Note that session tokens are only valid for a limited period of time and yet
there is no mechanism for refreshing or rotating them when they expire without
restarting Elasticsearch. Nonetheless, this feature is already useful for
nodes that need only run for a few days, such as for training, testing or
evaluation. #29135 tracks the work towards allowing these credentials to be
refreshed at runtime.
Resolves#16428
Similarly to what has been done for s3 and azure, this commit removes
the repository settings `application_name` and `connect/read_timeout`
in favor of client settings. It introduce a GoogleCloudStorageClientSettings
class (similar to S3ClientSettings) and a bunch of unit tests for that,
it aligns the documentation to be more coherent with the S3 one, it
documents the connect/read timeouts that were not documented at all and
also adds a new client setting that allows to define a custom endpoint.
Now the blob size information is available before writing anything,
the repository implementation can know upfront what will be the
more suitable API to upload the blob to S3.
This commit removes the DefaultS3OutputStream and S3OutputStream
classes and moves the implementation of the upload logic directly in the
S3BlobContainer.

This commit updates the s3 repository docs to clearly mark settings as
part of the s3 client settings, as well as those that are secure and
must be stored in the elasticsearch keystore.

The s3 repository plugin has "third party" integ tests which rely
on external service and configuration setup. These tests are really
internal verification of the plugin (and should be moved to real integ
tests). Running them is not something a user should do, and the
documentation has been out of date for all of 5.x. This commit removes
the docs, removing potential confusion for users.
Currently the default S3 buffer size is 100MB, which can be a lot for small
heaps. This pull request updates the default to be 100MB for heaps that are
greater than 2GB and 5% of the heap size otherwise.
and be much more stingy about what we consider a console candidate.
* Add `// CONSOLE` to check-running
* Fix version in some snippets
* Mark groovy snippets as groovy
* Fix versions in plugins
* Fix language marker errors
* Fix language parsing in snippets
This adds support for snippets who's language is written like
`[source, txt]` and `["source","js",subs="attributes,callouts"]`.
This also makes language required for snippets which is nice because
then we can be sure we can grep for snippets in a particular language.
We have 1074 snippets that look like they should be converted to
`// CONSOLE`. At least that is what `gradle docs:listConsoleCandidates`
says. This adds `// NOTCONSOLE` to explicitly mark snippets that
*shouldn't* be converted to `// CONSOLE`. After marking the blindingly
obvious ones this cuts the remaining snippet count to 1032.
We weren't doing it before because we weren't starting the plugins.
Now we are.
The hardest part of this was handling the files the tests expect
to be on the filesystem. extraConfigFiles was broken.
* changes `throttle_retries` to `use_throttle_retries`
* removes registering of all individual repository settings when the plugin starts. Not needed
* adds more comment about deprecated method in AWS SDK we need to implement though in a Delegate class within our tests
The syntax highlighter only supports [source,js].
Also adds a check to the rest test generator that runs during
the build that'll fail the build if it sees `[source,json]`.
I initially wrongly put this setting under `cloud.aws.s3.` prefix which does not make sense. It should be placed at the same place as `max_retries`.
Also applied @tlrx comments. We should set this even if max_retries is not set (when using default values).
Also added some documentation about this setting.
We can be better at checking `buffer_size` and `chunk_size` for S3 repositories.
For example, we know that:
* `buffer_size` should be more than `5mb`
* `chunk_size` should be no more than `5tb`
* `buffer_size` should be lower than `chunk_size`
Otherwise, setting `buffer_size` is useless.
For the record:
`chunk_size` is a Snapshot setting whatever the implementation is.
`buffer_size` is an S3 implementation setting.
Let say that you are snapshotting a 500mb file. If you set `chunk_size` to `200mb`, then Snapshot service will call S3 repository to snapshot 3 files with the following sizes:
* `200mb`
* `200mb`
* `100mb`
If you set `buffer_size` to `100mb` (AWS maximum size recommendation), the first file of `200mb` will be uploaded on S3 using the multipart feature in 2 chunks and the workflow is basically the following:
* create the multipart request and get back an `id` from AWS S3 platform
* upload part1: `100mb`
* upload part2: `100mb`
* "commit" the full upload using the `id`.
Closes#17244.
When using S3 or EC2, it was possible to use a proxy to access EC2 or S3 API but username and password were not possible to be set.
This commit adds support for this. Also, to make all that consistent, proxy settings for both plugins have been renamed:
* from `cloud.aws.proxy_host` to `cloud.aws.proxy.host`
* from `cloud.aws.ec2.proxy_host` to `cloud.aws.ec2.proxy.host`
* from `cloud.aws.s3.proxy_host` to `cloud.aws.s3.proxy.host`
* from `cloud.aws.proxy_port` to `cloud.aws.proxy.port`
* from `cloud.aws.ec2.proxy_port` to `cloud.aws.ec2.proxy.port`
* from `cloud.aws.s3.proxy_port` to `cloud.aws.s3.proxy.port`
New settings are `proxy.username` and `proxy.password`.
```yml
cloud:
aws:
protocol: https
proxy:
host: proxy1.company.com
port: 8083
username: myself
password: theBestPasswordEver!
```
You can also set different proxies for `ec2` and `s3`:
```yml
cloud:
aws:
s3:
proxy:
host: proxy1.company.com
port: 8083
username: myself1
password: theBestPasswordEver1!
ec2:
proxy:
host: proxy2.company.com
port: 8083
username: myself2
password: theBestPasswordEver2!
```
Note that `password` is filtered with `SettingsFilter`.
We also fix a potential issue in S3 repository. We were supposed to accept key/secret either set under `cloud.aws` or `cloud.aws.s3` but the actual code never implemented that.
It was:
```java
account = settings.get("cloud.aws.access_key");
key = settings.get("cloud.aws.secret_key");
```
We replaced that by:
```java
String account = settings.get(CLOUD_S3.KEY, settings.get(CLOUD_AWS.KEY));
String key = settings.get(CLOUD_S3.SECRET, settings.get(CLOUD_AWS.SECRET));
```
Also, we extract all settings for S3 in `AwsS3Service` as it's already the case for `AwsEc2Service` class.
