When doing a rolling restart we recommend disabling shard allocation to
avoid unnecessary recoveries. However, this advise is unnecessary or
even harmful when restarting nodes that do not carry any data like a
pure ML node.
This commit adds a deprecation note to the multiple data paths doc. It also removes mention of multiple paths support in the setup settings table.

This commit introduces a dedicated envirnoment variable ES_JAVA_HOME to
determine the JDK used to start (if not using the bundled JDK). This
environment variable will replace JAVA_HOME. The reason that we are
making this change is because JAVA_HOME is a common environment variable
and sometimes users have it set in their environment from other JDK
applications that they have installed on their system. In this case,
they would accidentally end up not using the bundled JDK despite their
intentions. By using a dedicated environment variable specific to
Elasticsearch, we avoid this potential for conflict. With this commit,
we introduce the new environment variable, and deprecate the use of
JAVA_HOME. We will remove support for JAVA_HOME in a future commit.
As per the new licensing change for Elasticsearch and Kibana this commit
moves existing Apache 2.0 licensed source code to the new dual license
SSPL+Elastic license 2.0. In addition, existing x-pack code now uses
the new version 2.0 of the Elastic license. Full changes include:
- Updating LICENSE and NOTICE files throughout the code base, as well
as those packaged in our published artifacts
- Update IDE integration to now use the new license header on newly
created source files
- Remove references to the "OSS" distribution from our documentation
- Update build time verification checks to no longer allow Apache 2.0
license header in Elasticsearch source code
- Replace all existing Apache 2.0 license headers for non-xpack code
with updated header (vendored code with Apache 2.0 headers obviously
remains the same).
- Replace all Elastic license 1.0 headers with new 2.0 header in xpack.
Today's network config docs are split into "Network", "HTTP" and
"Transport" pages, with unclear relationships between them. We often
encounter users with weird configs that indicate they don't really
understand how these settings all relate. In fact these pages are all
very interrelated, and the HTTP and Transport pages are almost all only
for advanced users. This commit brings these docs into a single page and
rewords some things to try and guide users away from the advanced
settings unless their configuration needs all the extra complexity.
It also adds a section entitled "Binding and publishing" which clarifies
the meanings of the `bind_host` and `publish_host` parameters. This is
also a common source of confusion amongst users.
It also clarifies that many of these settings accept a list of
addresses, and warns that this may not be what you want. Closes#67956.

We were depending on the BouncyCastle FIPS own mechanics to set
itself in approved only mode since we run with the Security
Manager enabled. The check during startup seems to happen before we
set our restrictive SecurityManager though in
org.elasticsearch.bootstrap.Elasticsearch , and this means that
BCFIPS would not be in approved only mode, unless explicitly
configured so.
This commit sets the appropriate JVM property to explicitly set
BCFIPS in approved only mode in CI and adds tests to ensure that we
will be running with BCFIPS in approved only mode when we expect to.
It also sets xpack.security.fips_mode.enabled to true for all test clusters
used in fips mode and sets the distribution to the default one. It adds a
password to the elasticsearch keystore for all test clusters that run in fips
mode.
Moreover, it changes a few unit tests where we would use bcrypt even in
FIPS 140 mode. These would still pass since we are bundling our own
bcrypt implementation, but are now changed to use FIPS 140 approved
algorithms instead for better coverage.
It also addresses a number of tests that would fail in approved only mode
Mainly:
Tests that use PBKDF2 with a password less than 112 bits (14char). We
elected to change the passwords used everywhere to be at least 14
characters long instead of mandating
the use of pbkdf2_stretch because both pbkdf2 and
pbkdf2_stretch are supported and allowed in fips mode and it makes sense
to test with both. We could possibly figure out the password algorithm used
for each test and adjust password length accordingly only for pbkdf2 but
there is little value in that. It's good practice to use strong passwords so if
our docs and tests use longer passwords, then it's for the best. The approach
is brittle as there is no guarantee that the next test that will be added won't
use a short password, so we add some testing documentation too.
This leaves us with a possible coverage gap since we do support passwords
as short as 6 characters but we only test with > 14 chars but the
validation itself was not tested even before. Tests can be added in a followup,
outside of fips related context.
Tests that use a PKCS12 keystore and were not already muted.
Tests that depend on running test clusters with a basic license or
using the OSS distribution as FIPS 140 support is not available in
neither of these.
Finally, it adds some information around FIPS 140 testing in our testing
documentation reference so that developers can hopefully keep in
mind fips 140 related intricacies when writing/changing docs.
We lost the `logger.transport.name` line in #65169 and I incorrectly
extrapolated from what was left and mangled it further in #66318. This
commit fixes things.
Today the docs use `logger.org.elasticsearch.transport: TRACE` as the
example for adjusting the logger config. This is a dangerous thing to
suggest since that's one of the most verbose loggers we have. An
accidental copy-and-paste of this example into a busy cluster can
cause damage.
This commit suggests `logger.org.elasticsearch.discovery: DEBUG`
instead, which is much more benign.
It also corrects the order of the levels and notes that `DEBUG` and
`TRACE` are only for expert use.
Closes#62758.
Include the Stack log4j config in the Docker image, in order to
make it possible to write logs in a container environment in the
same way as for an archive or package deployment. This is useful
in situations where the user is bind-mounting the logs directory
and has their own arrangements for log shipping.
To use stack logging, set the environment variable `ES_LOG_STYLE`
to `file`. It can also be set to `console`, which is the same as
not specifying it at all.
The Docker logging config is now auto-generated at image build time,
by running the default config through a transformer program when
preparing the distribution in an image builder step.
Also, in the docker distribution `build.gradle`, I changed a helper
closure into a class with a static method in order to fix an
issue where the Docker image was always being rebuilt, even when
there were no changes.
The _Important Elasticsearch configuration_ docs lists a number of items
that you should consider before moving to production. Today this list
does not include configuring snapshots, even though they're very
important to have in production. This commit addresses that omission,
removes some repetition from the introductory paragraphs, and notes that
this config is handled for you on Cloud.

Running the Elasticsearch Docker image with a different GID is
possible but trappy, since at present all the ES files are only
readable by the user and group. This PR documents a Docker CLI flag
that fixes this situation, by ensuring the container user is added
to the default group (which is `root`, GID 0).
I also added a test for this case, and refactored the Docker tests
to use a builder pattern for constructing the `docker run` command.
The existing code was becoming unwieldy and hard to change.
This commit clarifies that the preferred method for setting the heap
size is via jvm.options.d and that using the ES_JAVA_OPTS environment
variable is discouraged for production deployments.
Closes#51670, closes#50838.
Introduce a tiny base image for Docker builds. It aims to create a basic filesystem with as little as possible, which is mostly glibc, busybox and bash. A statically-built curl is also provided.
We still use CentOS 8 as a base. All the fun stuff happens in the Dockerfile.
There is no point in timing out a join attempt any more. Timing out and
retrying with the same master is pointless, and an in-flight join
attempt to one master no longer blocks attempts to join other masters.
This commit removes this unnecessary setting.
Relates #60872 in which this setting was deprecated.
The current `tee` command appends a definition to
`/etc/apt/sources.list.d/elastic-{version}.list`.
This can lead to duplicate lines and significantly slow apt-get
operations.
This updates the command to overwrite rather than append.
Plugin discovery documentation contained information about installing
Elasticsearch 2.0 and installing an oracle JDK, both of which is no
longer valid.
While noticing that the instructions used cleartext HTTP to install
packages, this commit replaces HTTPs links instead of HTTP where possible.
In addition a few community links have been removed, as they do not seem
to exist anymore.
Today there are a few places in the transport layer docs where we talk
about communication between nodes _within a cluster_. We also use the
transport layer for remote cluster connections, and these statements
also apply there, but this is not clear from today's docs. This commit
generalises these statements to make it clear that they apply to remote
cluster connections too.
It also adds a link from the docs on configuring TCP retries to the
(deeply-buried) docs on preserving long-lived connections.
